[Info/tutorial] How to manually configure a-gps server - Touch Diamond, MDA Compact IV General

Hi there,
This topic is about my experience of configuring a-gps manually with a French operator. This may help others.
I installed a few day ago the last french official HTC ROM (see here)
My Diamond is SFR branded (French Vodafone), and after upgrading from the native SFR ROM to the HTC one, I felt a slowdown to get a good GPS signal for the apps I use: Googlemaps and iGo8. The signal also seemed less accurate.
I decided to investigate this way.
First of all, some elements that may be obvious for most of you, but reminding them does not hurt:
A-gps is a system that enhances GPS performance, by connecting to an a-gps server. As a matter of fact, this server makes use of cellular network signal to locate you faster. For further informations, see Wikipedia a-gps article.
AFAIK, a-gps is different from Quick GPS (see here) In particular, config values for a-gps and Quick GPS are located in different registry keys on Diamond.
Now let's get deeper into a-gps:
You can, once again AFAIK (and you'll correct me if I'm wrong ), use two kinds of a-gps server:
Your mobile vendor's server (i.e. HTC)
Your operator's server
I remembered that on some phones (at least Nokia N95), you have to define manually your a-gps server when using SFR network.
For Nokia, the problem is that the port used by the vendor's server is blocked by SFR WAP connection.
This is not the case of HTC a-gps server, since using HTC rom does not inhibit a-gps: it only seemed slower to me than with my SFR rom.
Here are the registry parameters for a-gps, on the original HTC ROM:
Code:
[HKEY_LOCAL_MACHINE\Software\HTC\SUPL AGPS]
"EnableAGPS"=dword:00000001
"ServerPort"=dword:00001C6B
"ServerIP"="10.1.101.63"
"QosPerformance"=dword:00000059
"QoSAccuracy"=dword:00000032
"TimeBetweenFixes"=dword:00000001
"NumberFixes"=dword:3B9AC9FF
"GPSMode"=dword:00000002
I guess "10.1.101.63" is the IP address of an HTC's a-gps server (?!)
I then downgraded to native SFR ROM, and here was the same key:
Code:
[HKEY_LOCAL_MACHINE\Software\HTC\SUPL AGPS]
"ServerURL"="geoloc2.sfr.fr"
"GPRSConnection"="WAP SFR GPRS"
"Network"="WAP SFR GPRS"
"EnableAGPS"=dword:00000001
"EnabledPrivacyMethod"=dword:00000000
"CloseConfirmMsgTime"=dword:0000003C
"PrivacyMethod"=dword:00000000
"EnableLocInfo"=dword:00000001
"ServerPort"=dword:00001C6B
"QosPerformance"=dword:00000059
"QoSAccuracy"=dword:00000032
"TimeBetweenFixes"=dword:00000001
"NumberFixes"=dword:3B9AC9FF
"GPSMode"=dword:00000002
As you see, the server is defined with its URL, "geoloc2.sfr.fr" (known as one of SFR's a-gps servers), and some parameters are different.
Of course, you have to replace "WAP SFR GPRS" by the network connection you want to use.
I upgraded to HTC ROM again, and set the operator's rom values.
Now I've got the feeling that it's harder, better, faster, stronger (and more accurate).
By the way, QuickGPS is configured in the following key: [HKEY_LOCAL_MACHINE\Software\HTC\QuickGPS].
Note that, on SFR branded rom, this key does not even exist.
Hope this helps.

I've wondered why Quick GPS seems to replace the A-GPS feature on the diamond. QuickGPS doesn't seem to do a damn thing for me. From cold boot, I can stand in open air for 5 minutes until I even start to get a peek at a couple of satellites. How can we be sure that QuickGPS is even working at all?
I used to own a Nokia N95 that had the A-GPS feature, the GPS inside the N95 was pretty average. But with the A-GPS feature you could at least get a lock in under 10 seconds, every time. As long as you had configured your positioning server, (supl.nokia.com) and you had a data connection, then it was consistently under 10 seconds from cold boot. Without A-GPS it was more like 5 minutes plus, basically what I'm seeing on the diamond.
As people have noticed, using tools like Advanced Config to enable A-GPS breaks the GPS completely. Probably because of the missing settings such as you have outlined above, (I noticed these settings while poking around in the registry recently too). I wonder how we can find out what the server names for other countries are and get this working for eveyone.
Also, the IP address 10.1.101.63 is a private IP address so I guess that explains why it fails when you switch AGPS on, that address will never be contactable, so they must have used it for some kind of internal testing - but if it's working for you (with your new settings) then why did HTC choose to leave it broken for the other ROMS....

Well... Since I updated to this last HTC rom, QuickGPS "does work". I mean, it is an installed program, therefore available in "programs" list, and when I launch it, I can "download" data to update it. Though I don't have a cue of what use is made of this technology on Diamond.
I've always used Advanced Config to enable A-GPS, and it has always worked for me. But if it breaks the GPS, I guess you can do it from the registry by setting "EnableAGPS" value to 1.
I also tested a N95 8Go recently, and I had the same results.
But I'm not sure to understand your need: Diamond has both A-GPS and QuickGPS. I don't think QuickGPS is very efficient, but A-GPS is.
I do also think that setting the "ServerIP" value to "10.1.101.63" must work worldwide, since I bet this is HTC's a-gps server.
With this, GPS signal takes about 30 seconds to lock (at first use after soft-reseting, but may be under 10 seconds for next uses).
Did you give it a try?

Yes I have i too, and it connects and downloads data ok. But does it speed up a GPS lock? I don't think it does. I've hard reset and just run TomTom without QuickGPS and then with QuickGPS and I cannot for the life if me see any difference at all. In TomTom Satellite screen, you can see no data. If it was working, you should see all Satellite 'numbers' in their respective little boxes and then the tracking would begin almost immediately. But I'm not seeing this.

Many people have said that enabling A-GPS (via advanced config or direct reg edit) makes the GPS stop working completely i.e. never getting a lock. If you have got this working for you, as far as I know, you're one of the first! Lucky you!

No that IP address is within a private non-routable range for internal private networks and cannot be reached from the internet. Read this if you want more info.
I do agree though on the A-GPS being better, and with my experience with Nokia phones A-GPS is excellent. I don't understand what it is that QuickGPS is trying to do, because there is nothing quick about it. I thought it would be similar to A-GPS (in how it actually works) but now I'm confused :/

Now that's the sort of time we all should expect when using an assisted/quick GPS aid to the actual GPS chip. It should be lightning fast. So to me it says QuickGPS is pretty lame, as everyone is using it by default in all ROMS and there are many many people complaining about the GPS not getting a lock at all. So it can't possibly be working properly. And if it is, it still sux.
I'm going to try and replicate those settings you have above on my Diamond and see how it goes. I'll post back shortly.

OK well I've put all those settings in, but still no luck. It is not working. I've been waiting several minutes and still cant even get a fix.
It's not out of the realms of possibility that SFR's A-GPS server can only be used by SFR customers. After all, they assign you your IP address when you connect to the web on your diamond so they could easily lock it down so that random people cannot use it. In fact that would make a lot of sense.
I think we're close, but I guess we need to find a SUPL A-GPS server that is open to the public, maybe? Or certainly at least find out if HTC has one that we can use that is accessible via the internet... Maybe someone else has some ideas?

you can try: "supl.nokia.com" instead of "geoloc2.sfr.fr"

Have you tried this, and what port does it use?
I'd been playing some more and found out having it enabled really screws things up - TomTom thinks it has a lock, then it doesn't, then it does, then it doesn't, etc. It's really bugging out. So I just switched it off.
I'm really interested to know though if A-GPS will help with the ongoing GPS-Lag/inaccuracies problem, some poeple have reported that the lag is fixed in the new OS builds floating around but I can confirm that it is not fixed - in fact it felt like it was worse!
This GPS is causing too many headaches!!!

I'm also in Australia and i'm having the exact issues as you in regards to GPS lag and inaccuracies, i do however get a fix quite quickly, first time after a ROM change it takes a while but after that its somewhere between 30 sec and 1 min 30. I have changed my rom many times updating to all the latest custom ROM's, still its inaccuracy remains, its about 40 metres off on my device. I live inhouse number 16 and yet it tells me I'm at house 20. Like WTF........
What a pain in the arse!!!!

I got ip adress of HTC aGPS server!
its the 64.14.59.165
you got to just change the htc stock server of the diamond to this and its working well for me.

Tell me about it. Mine is about 50m off 90% of the time, sometimes it looks like it might be ok. The other thing I noticed today is that the 'speedo' in TomTom i.e. the bit on the status bar that tells you how fast you're going - which is usually very accurate - still tells me I'm going 15km/h, then slowly counts down to zero anything up to 20 seconds after reaching a complete stop! I am starting to regret spending money on TomTom. But to quantify that, I don't blame THEM, I'm just pissed I've shelled out so much for the Diamond + TomTom and the fkng things dont work properly. We have to get to the bottom of this!

Yep, its all the same issues I'm having, but not just with tomtom, I'm using iGo8 and garmin XT with no success.
This was written by me on another thread complaining about the GPS.
I called HTC support Australia and informed them off its fault with GPS lag and its accuracy, I informed them that over 50% of users are having this issue on the XDA forum, they told me that no fault has been logged and there isn't an issue, It may be time to call up the tech support and make some noise to get this issue resolved. its a pain in the arse and it shouldn't be happening.
I also called up Hong Kong Customer support the other day and they said the exact same thing...... i think.... the chicks English was just deplorable.
I think i may call the Australian HTC support again, and just irritate the **** out of them, hopefully this time they may have a solution for me.

Is IgO 8 working with A-GPS enabled?

Update/Refresh of GPS data
Maybe a stupid question, but how can I update the a-GPS data or does the device update the data automatically?

pls delete

Well, it does seem to be some kind of Navigation related server - I am trying now...

Well, it doesn't seem to have made a difference - but I will test some more...
lowrider - where did you find that IP?

What is the data amount when using AGPS ?
Are some data only transferred when opening TomTom ?

It should be only a few KB send, and then a little more KB received.
It should only happen when the GPS is activated (e.g. you start TomTom) and then the A-GPS would kick in then. It should not transfer any more data unless you lost the GPS signal, then it would assist the GPS in getting a lock again, and therefore transfer another few KB.

Kaiser GPS Enhancement Guide...

I see a lot of people with GPS problems these days & most of them have to do with not getting a fast enough satelite fix. There are several things you can & should do to enhance you Kaiser & it's GPS capabilities.
Firstly, use HTC's QuickGPS. Your device has to locate, communicate with & track numerous navigation satelites to get a fix that can be used by your navigation software of choice. Typically your device will need this information from 3 - 5 satelites, however there can be as many as 14. Each Satelite has Almanac information, this information contains suck as the current location, speed & Orbitital Patterns. This is where QuickGPS comes in. QuickGPS downloads this almanc information from servers & helps to guide your device the most appropriate satelites in your area. downloading the QuickGPS data at least once a week is key to maintaining quick satelite locks with your device.
Second, I see a lot of people using the HCT GPS Tool from the Polaris. WHY? Sure it can help to jump start your GPS, but there are other more functional programs out there that accomplish the same thing & much more.
Enter GPSGate! GPSGate is a light weight GPS utility that can be installed on a storage card & I could not live without. It is easy to use, it configures itself, it WILL jumpstart your GPS & allows you to do some amazing things otherwise impossible. GPSGate is a semi-commercial software developed by Franson. A trial version is free to download & the only difference between the free & the pay version is that the pay version allows you to Connect to GpsGate Server or GpsGate.com for sharing or logging over the Internet. GPSGate will help speed things up for you & also do many other things. Whenever you launch GPSGate, you GPS chip is immediately initialized & goes to work. Starting GPSGate before your navigation software or selecting the auto-start function gets your device working on connecting to the satelites NOW!
Ever tried running TomTom & Live Search at the same time? Usually it won't work & sometimes will freeze your device. Not when you use GPSGate. GPSGate will not only start your GPS faster, but it will also let you share the Kaiser GPS among several applications all at once.
GPSGate will let you use external GPS devices with your Kaiser & it will also allow you to use your Kaiser as a GPS receiver for other devices such as laptops, over A/S or Bluetooth connections. In fact, you can share the Kaiser's GPS over a network, ActiveSync, Bluetooth or HTTP. It will also allow you to Multiplex and split NMEA streams. GPSGate will communicate fast & flawlessly with a simultaneous multitude of programs. It will also allow you to start & stop your GPS Session on the fly.
I use TomTom, but I frequently use Live Search at the same time because POI's are always changing & new ones are added. Live Search is much better @ finding New things like restraunts & allows me to add them into my contacts & then select them thru TomTom all without having to start & stop each program allowing me to keep my focus on the road where it belongs.
Just download & install the cab, launch the program, follow the 2-steps on the screen & you're done.
Most of the important functionality is intact without licensing, (I think everything except the server based tracking & logging)

Share your position online using GpsGate.com
Track your friends on a map, see a remote person in Google Earth and more...

Not that hard to find.

I don't understand why this is useful. The GPS is already sharable in the Kaiser. I've run multiple GPS apps at the same time with no problems. The only use for GPS gate that I can see is uploading your position to their server.

If you use iGuidance 4 and are using a 6.1 rom, GPSGate is not only useful, it is required in order for your map to update. Others have reported that GPSPROXY will also work, and it is free.
Thank you, thank you, thank you!
I have been playing with 6.1 ROMS for two weeks and was about to give up because I could not get GPS to work properly (yes I tried everything that was recommended!) I was about to give up and revert back to a 6 ROM... and like a pheonix from the ashes I saw your post. Franson GpsGate did the trick. My GPS is working better than ever, heck my phone is working better than ever, many thanks to Sleuth and to you for fixing that last very frustrating and important glitch.

Then I'm just lucky I guess. I'm running 6.1 and I have Beeline GPS, TomTom and Live Search all running just fine. No GPS Gate or GPSProxy loaded.

Yes you are lucky. Many Tilt users are, but for the unfortunate, for what ever reason, we have GPS issues and this solved it at least for me. But I am curious... if you GPS is operating so wonderfully... why are you in this thread?
the same reason I am in here probably, to see what everyone is talking about and to see what kinds of GPS issues are out there that people are having. I know mine is working just fine but still checking out what is going on in case I run in to issues or see someone with issues that I might be able to help out or point them to this thread.
I read every GPS thread. I'm always on the look out for some way to disable Static Navigation. So far, no luck.
My original post in this thread was to ask what does this software give me that I don't already have. The stock GPS is intended to be sharable. If it does work like it's supposed then no proxy software should be necessary.
GPS quality varies widely from one Tilt to the next...
I have 2 Tilts and I can tell you one of them gets almost instant GPS lock while the other one struggles to ever get a lock.
I'm awaiting a second warranty replacement from at&t as the first one they sent has crappy GPS also. I've already warned them that they will continue shipping me Tilts under warranty until I get a replacement that works as well as my 2nd Tilt does.
One thing I like about GPS Gate is the Tray Icon. It would be better if the tap & hold menu had an option to toggle the GPS on/off.
It is nice that you can also use it to provide GPS feed to your laptop if you have such a need.

More than anything I was bored & wanted to write (Got my replacement & had time to kill while Sec. Unlocking, Flashing, etc.), lol.
Really I'd see a lot of Noobies complaining about not being able to use multiple proggies & having issues giving gps a quick jump. This post was really just kinda intended for the noobie that doesn't have the skill or patience to set up multiple port connections for the GPS. With GPSGate they don't have to. It all wil run thru the same V-port without them having to do any changes manually. I find that using GPSGate there is NO DELAY in the new application receiving the GPS data. Before GPSGate, every time I switched programs my device would hang for a bit. I also noticed a lot of people using or including HTC GPS Tools in roms for a jump start of the GPS device, & I figured why not something more useful.
+ I know that while a lot of us know about these programs, not many new guys do & when I'm out & about, occasionally I like to use my laptop W/ Streets & trips because all my customer routes are in there. This way I can use it for navigation & construction updates on long drive days. Of course I know not everyone has a nerd mobile like my truck with a PPC & Laptop Mount cradle, lol...but you never know.
Do these proxies keep the GPS receiver running all the time? what does that do to battery life?
It does what you TELL IT to do. You can start or stop the GPS on the fly. OF COURSE if you leave the GPS running it will drain the battery faster. But it only keeps it on for as long as you keep it active. Using the proxy itself will not change the discharge rate of your battery to any noticable degree.
Search for Franson GPSGate. You can read your heart out about it.
What should you put the baud rate to?
I mean I would assume higher means better but since my kaiser takes 10 minutes to get a lock I haven't really bothered doing any proper comparisons.
In any case all I get for the ten-fifteen minutes I've had this running is "GPS data but no position, running ok"
(Pretty much like GPS Tool, it runs and shows a lot of sattelites but never gets a lock. It does once in a while but it seldom and it'll always take ~10 minutes)
I have run quick gps.
This is with a cooked rom and a new radio though.
With my stock rom/radio I got a lock within 2-3 minutes after starting tomtom.

GSLEON3,
Although my GPS works within much problems or 3rd party software so far, I do appreciate your post on this as it clearly is helpful at his point of the ROM development.
I too am having troubles with my GPS. I have only had my tilt for a week or so but I can't seem to get the GPS to work well enough to be truly useful.
I have GPS Gate installed and it sometimes gets a lock and sometimes it doesn't. I have tried both TomTom 6 and iNav v3 and v4 with and without GPS Gate. I can generally get a lock sitting still and sometimes I can get a lock moving but anytime I try to use the navigation to go anywhere it either looses its lock within 10 minutes OR it only is able to track 1-3 satellites and thus HORRIBLY inaccurate showing me tracking between 50 and 500 yards from my actual location (if there are side roads or streets it almost never has me on the correct road). I have tried changing the position of the device to get better reception with no change.
I have also tried several different ROMS with different radios with no change. Are there some settings in GPS gate that I need to change to get better performance or do I have a defective unit? Any help would be appreciated.

I'm glad you were bored to write this. I, for one, thinks its a good source of info and a possible set of solutions for GPS issues. I dont think you can have too much possible solutions, so thanks for posting this up!
thanks much for taking time to post valuable information. i for one am no noob to windows mobile, but am too GPS. so, i definitely am willing to check into anything that could possibly boost performance of any component. thanks again and it does help alot with the new tool. one question i have is about the virtual port driver. the message comes up and ask me to soft reset for the virtual port driver to be installed, so i do. when i run the tool again it does the same thing, to me, indicating the driver didnt install. i go into advanced options and check the status and it says my driver memory is low, please soft reset. any ideas and thanks again.
GPS working Better at higher baud
I have been experimenting with changing the settings for my GPS in GPSGate. I posted earlier that I was having trouble getting it to work reliably and that I would frequently loose lock and not be able to get it back.
Here is what I have found works best so far:
Radio: 1.64.08.21
COM: 4
BAUD: 57600
Emulating: COM 1
TomTom: COM 1 at 57600
I really don't know why this works better but I have been able to consistently HOLD a lock once I get one. I still have trouble with it sometimes taking a VERY long time acquire a lock but once I have one it is working well. I will post if I find anything that works better.
If anyone has insight on this or finds any better settings please post.

Two problems with the XDA Ignito - Please Help

I have two problems at the moment with the XDA Ignito. It is a great handset otherwise.
The first problem is not one that concerns me too much. It is when I add recipient to a SMS and click to send, it shows an error message saying the format of the number to send to isn't correct or something similar but asks if I want to send anyway. I know that sending texts works fine though apart from that error which is just a little annoying if it is going to pop up every time I want to send a message.
The second problem is one that annoys me quite a bit more. It is to do with the GPS. I believe at the moment, it is getting the location from mobile phone masts and not the GPS satellites.
In GoogleMaps, it is saying My Location is within 1800m of a greyish/blue pale circle and there is a brighter circle in the centre of the big circle.
I've seen a video on YouTube of one using the HTC Touch Diamond and they have managed to track the satellites fairly quickly and my friend who also has the same handset as me says his GPS works fine. Takes a few minutes to connect to several satellites he said.
If anyone wants to know my GPS settings, I have program port on COM4, the hardware port is None and baud rate (or whatever it is is set at 4800) and mangement of GPS by software is set to be managed automatically.
I can admit that I have not tried this outdoors yet but have sat at a window with this so it should be working.
I think I've read somewhere about incoming beams being set on receive all incoming beams can affect this working? Is this correct? Oh, and all the other settings are defaults. Using the standard O2 ROM that came on the device. Think its dated the 8th Aug if that is any help.
Thanks in advance to anyone that can help.
I must also add, there does not appear to be any QuickGPS listed under programs. Where could it be?
Can anyone confirm whether this is normal? I understand those with a HTC Official ROM will have it but not sure why with my O2 ROM it is not listed. Could it still be installed yet not listed under programs for some unknown reason?
i can't help you with the sms problem, however with the gps - you will likely not get enough reception on your gps receiver indoors, since the satellites must be in sight, at least three of them to be able to determine your position by triangulation. so go outdoors and try it again, then it should work.
For some reason, o2 appear to have decided to remove QuickGPS. Whilst using the o2 rom I never got a gps fix even leaving the device for around an hour sat on the window sill.
I got fed up, flashed a new HardSPL and Dutty's ROM onto the device and then updated the QuickGPS data. This worked perfectly and within a minute or two I had full gps lock and tomtom was able to pin point my position accurately.
On a seperate note, line of sight isn't particularly important I found as I can sit in my living room around 4 metres from any window and it picks up satellites from cold as quick as standing outside. This is the same with my old phone as well (artemis) which managed to pick up a fix very promptly even tho it uses a different gps chip.
O2 haven't included QuickGPS as this functionality is supposedly included on the chipset and downloads the data from the carrier signal.
I found that with Assisted GPS enabled, my phone was tracking location using mobile phone masts, as soon as i turned it off the GPS performance was fine. (You can use Advanced Config to do this)

Advanced Config?
I think Advanced Config is a program that you install on your device. Gives you all sorts of options to make modifications to settings and tweak the device to improve on performance. I'm not sure I want to try this at the moment. Would rather have the device working as I think it should be using the current O2 ROM that came on the device.
I'm going to check out the GPS again when I go out later on and see if it works.
I still have a problem with the Text messaging where an error pops up before sending the message. Says something like format is not right for the phone number even though I have added the person from the contacts list. For some reason it just doesn't like the format the number is in.
Everything else with the device is fine though.
Oh one more thing, just out of interest, is it possible to obtain QuickGPS (CAB file) without having to change ROM? I once got the HTC Streaming Media application for my XDA Orbit from somewhere on this site.
Thanks.
I'd also be interested in Quick GPS as the GPS lock on my Ignito is terrible compared to my Orbit 2....
I've had a dig around and all I can find are failry incomprehensible registry hacks etc etc.
I've desabled AGPS via Diamond Tweak and I'll see if it's any quicker to get a lock now....
I'm a bit confused to bbe honest!
I've been outside with the GPS. It is amazing just how accurate it is now.
One thing I've noticed though is when I had a play around with the device this evening. It was asking me to enter my system and sim pins one after the other as though I had switched the device off. The device must have some how reset itself while in my pocket or maybe due to a period of inactivity.
I have pretty much the same power settings as what I had on my XDA Orbit.
I have the screen and phone power to standby or whatever it is called after 1min when running on battery and 10mins when connected to mains, could that trigger this in the XDA Ignito?
Thanks.
Still got to look into the SMS issue. Might be O2 settings related but got a feeling it is software.
glad you got your GPS working mate!
Still got the problem with the SMS error dialog box popping up before allowing me to send the message. Anyone have any ideas on how I'd get rid of that?
Thanks.

AGPS - any proof of it working/providing benefit? (new topic - pls read!)

Now please no groaning when you see this topic. I know the GPS has been hammered to death on these forums; this post is my vein attempt to see if one particular area of interest of mine has at all moved forward.
(let's also side-step the whole "does your GPS lag?" issue here too!)
(..and, for clarify, I'm referring to AGPS as in the use of the mobile phone network to 'assist' positioning by use of triangulation in areas of poor/no GPS reception, and NOT the use of QuickGPS to download current sat. info in an attempt to get a quicker initial fix)
I used to use TomTom Navigator v7.450; it worked (of a fashion! ) although one specific thing that never worked was that whenever AGPS was enabled (using AdvancedConfig or similar) TomTom would get a signal and then immediately drop it again.. on/off on/off etc.. the fix being to disable AGPS.
I must admit I'm suspicious about HTC having their stock ROMs with AGPS disabled by default - especially as this was initially a 'selling point' of the device and part of the sales blurb ("not only does it have GPS but really good GPS using AGPS".. oh the irony!) - have they themselves ever got it to work?!?!
Now TomTom Navigator v7.910 is out (have just installed it myself, currently waiting for an updated map to download). I have seen it muted that this now works with AGPS on the Diamond or maybe the Pro (ie. someone reports the above bug, yet claims it now works having moved to v7.910). Can anyone else confirm this? More importantly, can anyone confirm AGPS has given the Diamond any GPS-related benefit what-so-ever?? (ie. great if it doesn't stop TomTom working anymore, but does it actually improve it like it should?).
I'll of course try it out myself later today or over the weekend and report back.
Hope this makes sense.. cheers.
just tried TomTom 7.910 (9185) with AGPS enabled, and cant say i noticed much difference.
seems the same now with it enable or dissabled. Cant be sure tho, havent done a long journey yet.
Will update later/tomorrow.

Thanks for taking the time etc.
Interesting, because..
I've just taken a wonder outside and found I'm still getting the signal constantly being lost bug (looking at the screen that shows the sat. bars I have a good signal for a few seconds, then this goes and 'No GPS device' is displayed, then good signal back again and so on).
On this Diamond I'm using ROM 1.93.401.2 the the supplied radio (1.0.25.05), as I suspected this 'improvement' (potentially) noticed by you/others is more likely a result of a ROM/radio update and not a TomTom software update (guessing this AGPS bug isn't the first thing you try after flashing is it?).
Hmm..
nb. I'm using the exact same version/build of TomTom as you
hmmm... yeh, i'm going on a 60+ mile journey later, so will have a play.
Using Dutty's 3.4 ROM and Radio is BS14...
I thought that the whole point of AGPS is so you could help you get a GPS fix when indoors. Which I always thought was an unusual selling point when the entire purpose of GPS software is to help you find your way in the outdoors. Perhaps it could be more useful for those new tagging services that are popping up.
Anyhow I've been running a fairly recent version of iGo8 using Dutty's Rom 3.3 and 3.4 (both with that new radio).
With AGPS turned off, GPS signal is quickly attained and holds strong outdoors. Nothing indoors, naturally.
With AGPS turned on (via Duttys "AGPS Settings" utility), GPS signal is as quickly attained and flickers fully on then fully off, repeating constantly. When indoors, nothing at all.
So, with iGo8, AGPS seems to be a non-runner.
By the way, I once read that AGPS has to be configured to your particular mobile provider. Perhaps that's the issue?
Same here, with a-gps enabled signal drops constantly
after my journey yesterday, had the same problems as above.
tried with TomTom 7 and iGo8
I've never had any problems with GPS apart from slow getting a moving fix when the unit is physically very hot.
The main benefit of AGPS for me is that you can get your location on Google Maps within 1500m or so without enabling GPS.
It also proves A-GPS works.

Hmm, I think this is thanks to googles effort, not AGPS... Google uses Google Gears API which can position you by using basestations and SSIDs.
AGPS is correcting/updating the GPS data with actual almanac data sent from you mobile provider...

Yeah Google Maps does this on its own without having AGPS enabled on the Diamond. I believe AGPS is supposed to be more accurate than 1000m - 1500m though.
Oh and I believe the way that Google Maps gets its position depends on your mobile provider. I used to get the message "your location is not available" constantly on my network but one day (simultaneously as the iPhone was released in my country), the location was available. So I believe that the network flicked a switch for this technology to work.
AGps and TomTom
Hi,
agps have need to run to:
1) Carrier to inform MobilePhone here is (Is a Base Station Issue)
2) Public information about position
On mobilephone if is enable i think is need to have different information, and tomtom have old pattern to process agps information.
With googlemaps have new process and can use.
With my diamond agps run (googlemaps)
Cityhunter71
Please, don't mix the Google technology and A-GPS. They have nothing in common.
Google maintains their own privately held database of GSM-cellids which GMM can query to determine your position based on the current cellid.
A-GPS is a technology where the GSM-basestation itself receives GPS-satellitedata and relays it to the device. With this additional data, the GPS-receiver in the device is supposed to achieve a faster fix.
Have fun!
a-gps works with 7.450
i remember once that it was taking forever for the satelites to be found yet is was updating my postion on the map constantly via a-gps (which im sure was enabled by default in stock rom as ive never changed it)
a-gps is useful inside because you usually have your phone with you and to find a route, you need gps
Apologies for my erroneous post.
I realised my error today when I installed Google Maps on an ageing Blackberry I had unlocked to play with.
Started it up and lo and behold there was my location....thought I'd better head back here to suffer my shame ...LOL
Thanks for the input guys.
So - in summary:
Even with later ROMS / radios / software applications, there is still yet to be seen any benefit from the Diamond (theoretically) having an A-GPS capability.
RUBBISH!!
I personally subscribe to the theory that there is a missing link between the A-GPS driver type software and an info feed from the likes of the network operator, ie. it's all very well it picking up info on the network but without a back-end database to translate this it's useless.
As far as purpose goes.. I personally think A-GPS sounds on paper to be a great idea. Not a replacement for GPS, nor to be used exclusively indoors, but a good aid/starting point. For example, if I'm sitting in an unfamiliar office in London and wanted to use TomTom to navigate me a route to where I want to get to, A-GPS could provide TomTom with a rough starting point. Similarly, I often find myself launch a nav program (when I'm lost!) and standing there for up to 5 mins waiting for a fix.. at least this would give me an approximation from which I could probably work out myself where I was from looking around me. In my mind when you first fire up TomTom on the Diamond A-GPS should simply put you in the right postcode and start doing its stuff while the GPS seeks out its signal, and not still show me as being either at Home or its last known destination. But in any event - it seems not to work!! Bugger!!
I thought that aGPS was also to help hold a GPS signal when in tunnels, canyons, heavy forest cover (ie.Redwoods in this area, many tower to well over 300 feet!) or any situation where the signal from the satellites may be impaired, or even blocked completely.
Im running Duttys 3.5 and with AGPS on I will get a signal for 10 seconds, then it goes for a second, then back for 10. then gone. Turned AGPS off and all is well.
I can confirm that AGPS does work, some parts here in Finland it works and someplaces it does that on off thingy. once when I was just playing with my tomtom it got signal where it would never get it without it. but mostly here it doesnt work properly so i disable it.
But in Helsinki (larger city) it works properly and helps getting signal fast beneath tall buildings.
But yeah it doesnt work in my hometown so its kinda rubbish here.
Maybe it has something to do with how new are nearby cell towers or something. dunno
In Trondheim, Norway it worked with Telenor and gave me a signal indoors, but when I use it together with TomTom the signal gets lost periodicly, really really annoying since "everything" is already there. Probably just something with the co-operation with the regular GPS or something?
I think i got it to run.
I use tt7.910 on diamond with htc 1.93 dutch rom
My mobile provider is mobistar.
I can get a lock inside, tough it's slow(ie not as fast as outside).
When I fire up tt7 the almanac data is showing in the satelite screen.

[CAB] T-Mobile USA AGPS FIX

First and foremost I want to say that this would not have been possible without the XDA-Developers community, especially Da_G!! So say thanks to them!!
This has been tested by me and I can confirm that it works.
I use an AT&T Fuze on US T-Mobile's network. Obviously my phone is SIM unlocked.
I recommend you use the Blackstone Radio 1.10.25.25. NOTE: You must be security unlocked to flash the Blackstone Radio or any other radio from a Device other than the Raphael.

This cab file has made it possible for me to lock onto upwards of 7 satellites each and every time in less than 20 seconds. From a cold start(after a reset) I can lock in less than 20 seconds outside. From a warm start it's more like 5-10 seconds.
Inside my bedroom with no visibility at all I can lock onto upwards of 7 satellites in about a minute.
With all that said... Here's the cab file:
WARNING!! USE ONLY ON USA T-MOBILE!! Do not use on other carrier without making the appropriate registry edits!
WARNING!!This requires a data connection so do not use if you do not have a Data Plan or are willing to pay any charges to your account. I'm not responsible if you use this cab file and get a bill in the mail for hundreds of dollars because you didn't have a data plan.
For AT&T could I just edit the carrier to "medianet" or what ever we use? along with the nokia settings ? I'll play and see what happens later today. Thanks for your contributes!
I have the same phone as you dharvey, with an AT&T fuze unlocked for T-Mobile. However, I did not hard-spl mine because I have no idea if my phone is security unlocked or not.
My GPS works just as fast (under GPS Test), and can get a lock quickly without the cab. I'm looking at the registry edits and I'm just curious if this will improve GPS capabilities on my phone. Before you did the registry edits on your phone, what was the speed of your GPS before? Did you use GPS test? Or am I too far behind on the AGPS discussion?

Yes if you just wanted to make the manual registry changes without installing the cab and use "MEdia Net" (yes capital E) and use the Nokia settings it should work. Don't see why you would want to though AT&T has their own AGPS Servers.

HardSPL does not require a security unlock. Only if you wanted to flash a non-Raphael Radio like me would you need to security unlock the phone. This cab will install for you but I can't guarantee it will work for you unless you have a similar setup to me.
The time it took for me to get a GPS lock on my phone before making the above changes was upwards of 2 minutes. Now I'm down to 10-20 seconds without the extra.bin from QuickGPS.
Also I'm not using GPS Test. I have the same results with any GPS program I use from Google Maps to TomTom to GPS Test.

does anyone have agps working with at&t. as in you are able to be in a basement and using tomtom get your location.... im not talking about by the window and 30sec to connect. thanks
it took me almost a min from cold start (after soft reset) but only about 5-10 second after that. not bad at all considering that it used to take me upward for 3-5 mins with a lot of helps from other program (quickGPS + gpsToday) It was a bit cloudy outside, that might be the reason why it took much longer but still a huge improvement from my previous set up.. and now i don't have to start up anything else prior.
Thanks!

Nothing is going to give you position data in the basement. Nothing. AGPS? Forget it. Even if your carrier gives location data on the user plane to Tom Tom or whatever else, there is no way to get a lock underground.
I am amazed at what people expect GPS to be able do.

Especially considering the whole concept of GPS. GPS = Global Positioning System.
This is quoted directly from Wikipedia:
Basic concept of GPS
A GPS receiver calculates its position by precisely timing the signals sent by the GPS satellites high above the Earth. Each satellite continually transmits messages containing the time the message was sent, precise orbital information (the ephemeris), and the general system health and rough orbits of all GPS satellites (the almanac). The receiver measures the transit time of each message and computes the distance to each satellite. Geometric trilateration is used to combine these distances with the location of the satellites to determine the receiver's location. The position is displayed, perhaps with a moving map display or latitude and longitude; elevation information may be included. Many GPS units also show derived information such as direction and speed, calculated from position changes.

Click to collapse
GPS needs to be able to "see" the satellites in order to lock. AGPS(from what I understand) still needs a strong cellular signal in order to work too. If you don't have a strong cellular signal then how is it supposed to triangulate your position?
Using GPS in a basement will never happen. I'm shocked I can get a lock in my bedroom to begin with.

I'll 2nd this.... If I'm kidnapped and locked in a basement or dungeon of sorts, AGPS would enable me to load TomTom and I could find out where I was locked up.
On second thought, I could just call for help on my Rafael...
some conclusions about these AGPS settings using Orange in Spain as the data connection used to communicate with the Nokia AGPS servers.
It works!
AGPS data arrives to the mobile and help the GPS, to get Fixes.
but there is one small problem, as AGPS is now enabled, it seems that the GPS SW (gps test, google maps, gpstoolpro, gpstoday, tomtom...) waits for the AGPS datat to be processed before it tries to get a direct fix with the satellites. Sometimes this can produce a delay. I mean that before, the "kick gps tools" such as gpstoolpro, gpstoday used to get really quick fixes without the AGPS settings. Tomtom used to stay really longer if it was not kicked by them. Since now that i have AGPS, Tomtom can acquire a fix very fast, but the "kick gps tools" waits really longer until they get a fix becasue they seem to wait for the AGPS data to be processed..
So it seems that the AGPS settings make tomtom get faster cold & hot fixes, but slow down the "gps kick tools" cold & hot fixes.
before AGPS settings:
cold start:
gpstoday 15 sec
gstoolpro 15 sec
gps test 1 minute
tomtom 2-3 minutes
hot start
gpstoday 6 sec
gstoolpro 6 sec
gps test 15 sec
tomtom 1 minute
after AGPS settings:
cold start:
gpstoday 20-30 sec
gstoolpro 20-30 sec
gps test 20-30 sec
tomtom 20-30 sec
hot start
gpstoday 15 sec
gstoolpro 15 sec
gps test 15 sec
tomtom 20 sec
times are aprox.
What about your experiences with these AGPS settings?
Share please.
Dharvey, when you fire up google maps, are you using the "Use GPS" option for getting your location? Also, what do you have set in your "External GPS" settings? Did you put the "GPS program port" to COM4 as has always been suggested? Also, hardware port = none? Thanks for all your work on this.
Just a small note, the cab actually has a typo (and it's my fault b/c i was a little inebriated when I typed up the post containing the info, and have since edited it!)
nokia.supl.com should be supl.nokia.com
It still works because the IP address is used directly unless it fails, in which case it rolls over to the hostname. But still, fixing it now rather than whenever nokia moves the supl server to another closet and your a-gps breaks would be a good idea

Just a small note, the cab actually has a typo (and it's my fault b/c i was a little inebriated when I typed up the post containing the info, and have since edited it!)
nokia.supl.com should be supl.nokia.com

Good call. I'll fix this right now.
EDIT:: Cab file fixed with Da_G's correct URL.
So would using the Nokia servers still work if you were on AT&T?

I don't see why not. As long as you change the connection type to your carriers first this way your AGPS will still connect.

Nothing is going to give you position data in the basement. Nothing. AGPS? Forget it. Even if your carrier gives location data on the user plane to Tom Tom or whatever else, there is no way to get a lock underground.
I am amazed at what people expect GPS to be able do.

@everyone - correct me if im wrong but isn't the Agps on our phone supposed to give you an approximated location whether you are connected to satellites or not?

To buy or not to buy? also, cool whip.

Hi, I'm a new member, but more of a lurker. I originally planned to buy a Hermes but after reading about all the hardware problems I decided to go for the Kaiser. My question is, are there any major problems with the Kaiser? I know of the ImageON driver issues, are there any other hardware or software issues?
I don't think there's any fundamental problem with the hardware. The 3 Mp camera is not great, but what do you expect of a camera on a phone?
There a lot of ROMs, official and cooked, you can choose one that suits you.
Mine works pretty well with the original WM 6.0 ROM or the HTC official 3.02 one. With more recent ROMs or radio firmware I have problems with GPS fix times and access to WiFi routers.
Thanks for the fast reply!
I'm sorry to ask this in the Kaiser forum, but would going for the Hermes be worse than the Kaiser? They're essentially the same, except that I've read of a lot of h/w problems on the Hermes.
Hermes is awful next to the Kaiser. I still have mine here, had to use it while my Kaiser was being repaired a few months ago and it was just a PITA. Slow as hell, deeply embossed and lower quality screen,... But I can't talk of hardware problems with it.
If you get a 2nd hand Kaiser, the important points you need to check is that 3G is working (early units had faulty 3G hardware that would fail after some time, but most should have been warranty-fixed by now), and that the USB port is not broken as some tend to break it by shoving the stylus in it instead of the storage place.
I guess I know which phone I'm going for thanks!
One more question! sorry lol, I know the Kaiser has A-GPS, do you have to pay for it? If I put TomTom on my Kaiser will I have to pay for using the assisted GPS?
Also, is CorePlayer working fine on the Kaiser, mainly with xvid/avi files?
A-GPS aka QuickGPS will want to download a small file off the internet at least once a week, be it through Wifi, Activesync or whatever else is available to get satellite data and allow for shorter times to first fix, that's all. And if you don't want to use it you're not forced to, it will just take a little longer to get a fix.
So nothing to pay, except if you decide to download that little file over GPRS where your data fees would apply.
Coreplayer works fine, I personally reencode my videos in 320x240 divx for viewing with it. Never really tried anything else for video.
Alright, thanks amigo!

AGPS is not the same thing as QuickGPS (though it took me ages to realise).
Quick GPS is what you describe and is generally considered to be worthwhile.
AGPS is similar, but it downloads more specific information which (I believe) is based on which phone masts you're near - and therefore should be even better for getting a good fix. The problems are A - It will cost money if you have to pay for your internet connection and B - apparently (though I've never used it) it will sometimes update the data while you're actually using GPS and as a result lose your fix while you're driving somewhere. A lot of people don't like AGPS at all.

Well.. it is in some way. The problem is that AGPS can be implemented in different ways up to different extents...
The first thing is what is mentioned above - downloading ephemeris data from the net instead of getting it directly from the satellites, which would require continuous link with each satellite for about 1 minute. First fix time is thus shortened as the data for 1 week is stored locally. This is what QuickGPS and SeaSGEE do.
The usual "Disable AGPS" in KaiserTweak / Advanced Config is a second thing. It switches to a different position calculation algorithm that is supposed to work better in low signal conditions, by extrapolating the movement at the time signal is lost and trying to guesstimate how it could evolve everytime some signal is received. But many people don't like that as it's only giving decent results in certain conditions like driving, and when walking, geocaching etc it does nothing more than giving wrong info.
What you mention by using cell towers and an internet database is also something that can be done under the AGPS naming, but AFAIK it's not implemented on the Kaiser.
It sounds like you know more about it than I do so I'll bow to your greater knowledge
