GPS

Hi.
I know this might already be confirmed but I did a simple logging on com4 and found that the gps i really there. Will go out later today and test it again but this time outside. I attach the logging to.
One more thing, it´s kinda strange the gps is always on, atleast htc could disable the gps for real if they´r not gonna use it. The battery time would increase alot.

GPS is enabled, how more i read about it it has to do with something like no antenna is connected. When i use the GPS test tool it finds a GPS on com4 and have one sat in screen.

lol
to cold here to go outside, put mine by the window the other day and got one sat with GPS test.

Here is mine, I found also one sat, it was inside the house before the window. GPS is working but its no sensitive enough, could be no antenna.

Where can I get the software to access the GPS? Sorry for the simple question, I've been looking around online and can't find it.

Thanks. I only get one satellite as well.

Im very happy!! 1 sat. is better than no sat.
hope we can get GPS running for real.. soon

As jockyw2001 also wrote: We need pics of the inside of S730, both pre-production (with antenna) and current production model/or service manuals of Kaiser and s730. Then we will be able to see how the antenna looks like and where is it connected.
Idea!!
Is it possible to make (by HTC) the hardware switch on s730 board, which is disconnecting the antenna?
Then, the antenna could exist and the new ROM could enable this feature in future.

Is there anyone here in the forum that actually has GPS working and getting a few sat signals etc.
it will be intresting to see if there is any difrerences in there registry. If someone has it working can they post the reg. info so we can compare.

GPS is not always on. It has some power saving timeout and 'wakes up' when communication port is openned and GPS data are read.
On the COM4 is not directly GPS, but GPS intermediate driver (someone knows it from PPCs), that allows more application can read from one COM port.

oh
something else i thought of is there a working driver for the gps on the phone or not? Im not really sure if it needs one.
Also i found a pdf of the msm7200 chipset. not that much to look at but you can see the gps etc and how its wired and i presume an antena at the end.
Follow the link http://www.3gchipsets.co.kr/download_library/pdf/msm7200_chipset.pdf

Here is a s730 with GPS:
http://forum.xda-developers.com/showthread.php?t=337796&page=2

yes it was a preproduction model. In the official models its not working. We need to find out what is difference between both models

I am still new to the smartphone world so I cannot be of too much help, but this is what i've seen thusfar;
With GPS Test I have gotten sats on com 2,4 and 7, every satellite I pick up is at 0 on the little map locator screen. The GPS tool never gets past GPS starting up, stays fixed at 1D and no other info gets downloaded.
My testing has been in very cloudy weather over the past few days here in Texas, today though its nice and clear so I hope to get more done. I played a little with the baud rate but nothing came of it. When I did pick up a sat it was gone in 10 - 20 seconds. I did at one point pick up two at once, both in the same direction. Overall I have seen 6 different satellites, only 2 at once, and all from the same location. Could be thats the only open direction I had for visibility at the time.
I do remember reading somewhere that the GPS chip had a small antenna actually built onto it. Hopefully we can get it working soon.

could you find out where you have read it?

This is one place, I cannot find the other place, it was their blog or one of those other sights that has a blog in playing with the pre production unit they talked about its processor and GPS... I'll try to dig it up.
Getting really annoying having the tool stay in "GPS starting up" mode none stop. Need to find the HTC version that the pre prod. phones were using or figure out how they nerf'd it.

Yes, I think I saw the same blog forum, but this blog is out now :/.

How to activate GPS? [TyTn II]

Hello all,
I've been looking for a way to start my GPS when I want it, I want the red led to blink at me!
The only way I can get it to work is with googlemaps or tomtom, that software then magicly activates the module for me. Why can't I do that, I am your master little computer!
Also if I try other software like nav4all and amazegps, I just get the message: No GPS device found. It's driving me crazy.
I would be very gratefull if someone could please tell me where to find the switch, button to activate the GPS module when I want it on. And maybe also tell what I am doing wrong in relation to other software that tells me I do not have GPS.
Thanks allot!
Loeder

Compatible software switches it on whenever you wish master.

Whats wrong with the orange flashing light you get with Tomtom working? As far as I know, without any jiggery pokery installing cabs, the red light is reserved only for low battery or problems so if you're really keen to have a flashing red light, let the battery discharge below 5% (that ought to give you a few mins usable GPS usage).

You can if you learn programming skills and write a module to load and use the devices GPS driver. These products you have that don't detect the TyTN IIs GPS capability don't have that built in, hence they cant 'see' any GPS. A simpler way is just to write to your preferred GPS software provider and ask them to make it compatible with your device or buy/use something that already is fully compatible.

I trust the above addresses this (although I suspect your usage of 'module' above means this is no surprise to you).

At least the MWg Zinc II has it built-in to the COMM MANAGER - not that I would see a need for it since good application should be able to find and use the GPS module anyway, however, it tells me that there should be a way in WM to turn it on manually!

Loeder:
Most GPS apps have settings menu where you can set the GPS settings, for the Tilt/TyTN II/Kaiser, COM 4 and 56000 always worked for me.
Flying Kiwi:
The red light Loeder is talking about is the "GPS Active" light, not the "low battery" light.

Thanks for the help!
I actually installed some sort of device driver that made my GPS crash everytime, now a hardreset saved me but the good thing is that I can now run (http://www.amazegps.com/welcome.php) free navigation that does the job same as TomTom (to think i almost spent €50,-).
Still, it is ... quit annoying that they did not put a simple button in the comm menu or otherwise...
TyTn II has been great sofar.

Yes but when you spend that €50 you get maps loaded for your location, so if you don't have a 3G or Data connection when your trying to figure out where the hell you are you can at least see roads to travel on. This is the one thing that bugs me, I don't live in the city so when I'm out "Joy Riding" and want to find where I am going sometimes I don't have a cell signal so my phone is useless with Google or Live or this amaze program, Plus I purchased a version of streets and trips but of course they are not nice enough to include a WM version with your laptop version so now if I want that on my phone i have to buy it AGAIN... I may go that route since looking on Tom Tom even if I was able to install the V7 cab they don't sell US&Canada maps... Or at least I can't find where to buy them from.
Scratch that... Microsoft doesn't have a version to go with streets and trips since the 05 version I think... so Now I'm limited to navigation programs that require a data connection... WTF... Unless someone can tell me where TomTom is hiding their US maps on the map purchase page for Navigator 7

If you want to turn your GPS on, then use a little app called GPSViewer or VisualGPSCE, both are freeware and attached for your convenience.

There is another application called GPSTest.exe, it is attached.

Turning it on does not mean it can automatically be used
Irrespective of whether a utility is used to turn on GPS, I don't imagine it would enable a non-compatible package that can't initialise GPS itself, to work with the TyTN II though.... or will it?

Thanks MACkjam, another little usefull apps, all i knew was just GPSTest and it's incridible.
My main app for GPS was still Garmin XT, free map available for Indonesian region.

I would once again say thank you for all the help, and the programs you posted allong with your replies.
I hope this thread will be helpfull to others aswell.
@Berretafreak: I have never not have a signal sofar in europe, but I'm sure there are places, even in europe, that do not provide a decent signal. Also I have a regular TomTom .

The zinc ii does NOT show gps and does not have the traditional mgr. It says wireless.
BTW tt7 nav with na maps is available and works perfect.
I have tried some com cabs but they do nada.

Diamond GPS inflight

Hello! I used my Diamond inflight (from cockpit B-737) using NAVGPSpro 4.5 its didnt work , but on the ground i can use all my GPS programms. I have tried to switch ON/OFF phone, soft reset, started all my programms but.....
Could someone help me please? Why Diamond dosent work inflight?
P.S. Glofiish X900 working well. And sorry for my english, i am from Russia

I am no expert, but are you maybe travelling too fast for the Diamond GPS to lock on?

You need to have an extra satellite fix for aviation software to give you your altitude.

But X900 working excellent. What are restriction to use Diamond GPS? I didnt find its. NAVGPSpro is special programm for aviation. And one more: sometimes i have had successful attempts.

i'm gonna go with this answer, it sounds cooler.

I've tried Diamond inFlight using IGO8, TOMTOM7 also OZIExplorer and it worked fine. It takes some time to find satelites for the first time.

Possible that the heating elements in the windows are limiting the GPS reception? Do your 737s have the eyebrow windows?

1.May be but X900 working well.
2. No they are closed by panels

i was able to get the GPS Cycle Computer to work, but with no altitude measurement. top speed = 503 mph
tomtom 7 would not work. waited several minutes, no sat lock.

isnt this illegal??
radio communication is supposed to fk up the flight instruments n stuff.

if that was true then every osama fu*kstick wanna be would be bringing down planes just by turning on the gps. the fact is back in the 70's and 80's there was a problem with interference but the technology is better now so its not really a problem any more.

GPS is passive-recieve-only, its based on a bunch of satellites sending accurate timestamps to you for triangulation. So no, it won't **** up nav systems any more than listening to the radio.

On the next picture, the altitude profile show some gap (i put some pink in the image): 6 500m to 3 500m in one second.
Those gap appear also on the map : the step on the red trace.
I've got no explaination for those gaps:
My flight was at 4 000m or my descend is stronger than the altitude profile show.
I'm not sure it is safe to trust the altitude given by the GPS in a plane.

That's the common misconception.
It is illegal for passengers to leave on radio communication devices during a flight. However in most cases its harmless.
I remember reading that only a few frequencies which do interfere with aviation communication. and these frequencies are NOT currently being used by ANY mobile phone networks.
Haha, i do love it though when i play with my Diamond on the airplane while having it on flight mode, and people around me are like staring.... and thinking OMFG THAT DUDE IS A TERRORIST HE HAS HIS PHONE ON!!!!!!! I even had a old couple remind me that i have to turn off my phone.... haha very amusing.

WTF is wrong with the Kaiser's GPS

Seriously, I've seen it be slow, mysteriously not work until after a soft reset, suck down all sorts of battery..... but this...... this is new.
Trust me, this picture is not doctored. And my desk is not moving at 117mph. And I live over 210 miles from where these coordinates are. You just gotta see the picture. It's been like this for 30 minutes so far, and right now I'm actually moving at 142mph. My desk would actually be CLEAN if it were moving that fast you'd think! ahem!

QuickGPS, same thing a lot of people use for sanity checking their GPS. GPSToday refused to get a fix, so I fired it up to let it run and I discovered the GPS was reporting that nonsense.

The Kaiser's GPS is crap, but generally if it's "warmed up" it will work fine inside. My house is all wood, so it is fine in that regard.
I've used GPSes for several years and had the Tilt almost a year, this was not a new experiment I was doing. At least, not intentionally!

Mine isn't crap at all. It's better than most and certainly better than my wife's Xperia. The Tilt is somewhat different to the TyTN II and also depends on what rom you have etc etc etc. In fact the rom plays a huge difference in the gps and other apps.

Nope, it's complete and utter crap. If you don't think so, you haven't used a decent GPS ;-)

This has happened to me on two occasions in the past - seemingly completely at random. Stopping & starting the GPS didn't solve the problem on either occasion (actually just stopping TomTom and then restarting it a couple of minutes later). The only solution was to soft-reset it.
I think I was relatively near to the location the GPS thought I was, I also seem to remember it was only showing one satellite as sending valid data and it was this data that was erroneous (obviously the Kaiser was at fault). However a soft-reset solved the problem and I haven't seen this behaviour for about 4-months.
One soft reset every four months would be a blessing.... Other issues on the phone mean it gets a soft reset at least once a week anyway

a gps only get positions
speed and the rest if calc from
when it gets new positions
if not moving speed and compas and all that
is based on absent data and if you have
a very poor signal like you get in doors
those calc's can act up

What does your GPS do that my WM 6.0 ROM equipped TyTN II cant? Cold satellite locks in about 30 seconds, hot satellite locks nearly instataneously? You don't get that with your TyTN II? Ah but then you have a WM 6.1 ROM - say no more. Is it any coincidence that MACkjam also has a WM 6.0 ROM? The hardware is capable enough, as long as the right ROM is used and in this regard newer is not better.

Has this been confirmed? It does not really coincide with my experiences.
The history of my TyTn II:
- stock 6.0
- radio 1.65.14.06
- GPS worked fine
- stock 6.1 flashed
- GPS worked fine for a long time
- GPS started getting weaker and weaker, gradually over time
- PDA Corner Ultimate V21 ROM flashed
- radio 1.71.09.01 flashed
- GPS keeps getting weaker, nothing seems to help
Currently, it MAY connect on the highway after 5+ minutes, or it may not. Or even later. Never sooner. Once I have a lock, it is steady, though. Walking around town will never give me any lock anymore, not even after 30 minutes. Not even in the park, which is not very small. I have tried clear skies. Using TomTom, Google Maps, or GPS Test all at once or seperately makes no difference. My GPS is practically useless by now.
Is there anything that could be done to fix this? I should be much interested.

What would you accept as confirmation? Is a long thread here at xda-dev about *Hopeless* GPS after 6.1 Update? sufficient for you? Is the fact that while you had WM 6.0 on your Tilt, your GPS was fine (the whole time) good enough? I've had my TyTN II since 1 October 2007 and the GPS performance has not deteriorated under the signature ROM to any noticeable degree (although when it had WM6.1 on it, the difference was very noticeable).

Not sure if it's related but one of the causes of deterioration over time with regard to battery reliability, is that the contacts get dirty. If the battery isn't transferring all its power to the GPS circuitry of the phone (GPS is very power hungry) then this would explain poor GPS performance. If you have some contact cleaner or Iso Propyl Alcohol and Q Tips, use them to give the battery terminals and spring contacts a careful but thorough clean (making sure not to bend the spring terminals). You'll also need to be careful not to get the cleaner anywhere other than on the cotton bud and connectors as there are moisture sensor stickers on the phone which could be triggered if they get wet. You could also try cleaning the 4 corner gold connectors and plate on the back of the battery. This connection (along with the antenna sticker) seems to have some effect on RF signals.
FWIW I've had occasional glitches as originally referred to in this thread. I've put it down to radio interference as in each case I was in an area where I imagine there were strong amounts of residual/stray? RF in combination with tall surrounding buildings. My GPS also said I was travelling at about 120 mph at the time. Powering off then straight on again didn't fix it and I actually couldn't get it to work properly again until I got home and after I synched with my PC (maybe something to do with a QuickGPS update).

I flashed to hard SPL 3.56 from 3.29 and now I get a GPS fix consistently in under a minute.

WM 6.0 works!

In fact, it was my brother's phone then, and he said he never had any trouble with his GPS under 6.1, so that I did not expect the critical change to have happened at the switch from 6.0 to 6.1. I rather thought it was some hardware gradually deteriorating.

I apologize, my brother flashed to 6.1: I hadn't thought of his flashing the radio as well, which seems obvious in hindsight. I don't know what radio he had at the time.
According to your advice I tried the stock 6.0 ROM including radio 1.27.12.11, and it worked! Thank you very much! I remember searching for GPS fix threads a while ago, but somehow I never found these useful threads. With this ROM+radio my GPS always connected within 1-2 minutes from the window sill, excellent.
But then it gets interesting. I flashed PDA Corner Ultimate X2 V5 (WM 6.5) while keeping the old radio. GPS still worked like sunshine! So I guess in my case it is this old radio that does the trick. I got no sound, of course, so I changed to 1.71.09.11 as recommended by the ROM's chef. Then GPS worked as badly as before, though perhaps a trifle better (not sure). In any case it was not workable.
I think I should try some other old radios as well, to see whether one of those is compatible with both WM 6.5 (or 6.1) and my GPS.
About your advice of cleaning the battery's contacts: good to know, but I suspect that this is not my problem at the moment. Because 1.) I often get seven green bars in GPS Test and still 15+ minutes before a fix, and 2.) my GPS worked like a charm with the old 1.27... radio.
Now I think I must switch back to 6.0 again. I hope I will not be put off too much by the disdvantages, I have never used 6.0 before. I don't care about the menus, I never use them anyway (rather SPB Mobile Shell and Ultimate Launcher). What other disadvantages are there to 6.0? Can you recommend a good custom 6.0 ROM + radio?

I had tried the flash to 3.56, too, but I didn't notice any difference, alas.

I just tried the NIKI radio 1.58.11.07: it works very well! My GPS gets a cold fix as fast as with 1.27.12.11, usually under 1 minute. Unfortunately, no sound either (using WM 6.5).

Have we been tricked on AGPS by SE?

The X1 has been marketed and advertised as having aGPS but thus far it seems no one can get it working. It seems SE no longer maintains a working SUPL aGPS server. The server found in the settings is in the 10.1.x.x IP range which is NOT a real server. It is a private IP (look up network address translation on wikipedia to see what that means). I am tired of 5-10 minute locks sometimes and terrible performance in a city with tall buildings. I am getting ready to visit NYC and this will probably render my GPS useless. When I visited Georgetown which isnt even as dense, the GPS went nuts. Do you think we can do something about this? Does anyone know any public SUPL aGPS servers? Also can someone with a completely stock X1 ROM post the contents of the following reg key:
[HKEY_LOCAL_MACHINE\Software\HTC\SUPL AGPS]
Please post your ROM version if you do. Thanks!
*edit. Please read!*
Ok, let me throw in a little explanation to aid this conversation. A stand alone GPS works by listening to satellite signals and calculating your distance from each satellite it hears. In order for this to work the gps reciever needs to know where in the sky the satellites are. The satellites broadcast what is called ephemeris data that contains this info. This is why your initial lock can take quite some time. If you start listening in the middle of the broadcast you must wait for it to start again. If you loose signal during the broadcast you need to wait for it to start over. Once you have the ephemeris data you can begin working on a fix.
QuickGPS is NOT aGPS. What QuickGPS does is download the ephemeris data from the internet so that you dont need to download it from the satellites. This can speed up your initial lock.
aGPS is another thing entirely. It is not a carrier service. All you need for aGPS is a GPS reciever and an internet connection of ANY kind and an aGPS server to connect to. You could use wifi. Since you have a phone though and you are moving it makes sense to use a cellular connection. In this case your carrier can only charge you for data transfer. Lastly, your carrier may maintain their own aGPS server. aGPS has several functions. First it detects the cell sites you are connected to to get a rought idea of where you are (like google's mylocation feature). Now that you know where you are you know which satellites to look for (since aGPS also does have ephemeris data). Once you start recieving GPS signals, rather than calcutaing a fix yourself you can send the info about the signals to the server which has a much more powerful CPU. It will calculate a fix for you and send you your position.
Another thing. GPS software does not need to be in any way aware of aGPS or QuickGPS. These are both utilities used directly by the GPS reciever itself to help get a fix. GPS programs use a standard API to get position information from the GPS reciever. How the underlying reciever goes about getting that information is of no importance to the GPS program. Wouldnt it kind of suck if every GPS software had to have its own algorithm for calculating a GPS fix from satellite location data? These are not simple calculations (one of the reasons it is nice to have a server doing the calcs for you). This is why there is an API for this.
Hope this clears up misconception and leads to a more informed discussion of the issue. Posted from my X1 with Opera Mobile 9.7 on my way to NY with CorePlayer playing the music and iGo8 navigating running in the background. I love this phone.

On my X1 with German stock R3A it looks like that:

"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

aGPS seems to be switched off!? Here has been another discussion about that issue.

From what I know, AGPS is a service provided by your operator. You need to enable it
in "Settings->Phone->Services" to get the right settings. Maybe this IP is just dummy.

is agps the thing used to get a quickgps signal, if so mine works. u have to manually update sometimes (lasts 7 days).
might not be the same thing, not sure

I've been able to update my QuickGPS also with A-GPS turned off - it must have been useless until now...

My X1a (stock NAM R3A) has following values...
[HKEY_LOCAL_MACHINE\Software\HTC\SUPL AGPS]
ServerIP: 10.1.101.63
EnableAGPS: 1
GPSMode: 2
NumberFixes: 999999999
QoSAccuracy: 50
QosPerformance: 89
ServerPort: 7275

QuickGPS is something the GPS software should use. Enabled or disabled, if iGo8 for example does not use it, it's all the same. And I can't tell for sure if iGo and Garmin are using it.

No offence, guys..
But here we go again, with the a-gps. I wonder why a-gps is mostly discussed and asked by Sony Ericsson users And wonder why just SE users always feel tricked...
1) Let's think.. So with the IP thingy you expect that the a-gps will connect to an internet server, right?
Myself, I've never experienced problems with GPS in X1. Living far away from a crowded city, the reception is fine. And in the city, no problems as well. During AS, it downloads the coords through quickgps and later my GPS gets fixed in about 20s (that's when Tomtom or other GPS app is able to navigate). Of course in URBAN AREAS.
2) if you look here, it has been discussed http://forum.xda-developers.com/showthread.php?t=413893
If you google the ip 10.1.101.63, you'll find that everybody is talking about it almost everywhere, but nobody actualy knows, how the a-gps on HTC should work (coz nobody ever saw it working and people are know poorly about what that really is) - if triangulation or something else..
So no problem at all. Coz triangulation through cells won't help you with navigating at all.
Cheers
edit: sorry for being arsey

where can i find the file to check? my phone is completely standard. is it not possible to have both gps systems turned on and it use what ever is best at the time?

of course it is going to be switched off! Why would it be on if you were not using it!
If you want everything to work 100% properly then use a official rom like me

Use this IP-Adress: 64.14.59.165. (ping supl.nokia.com)
With this I get a lock within 1 second, without in about 10 sec. There isn't any data connection established,
but it seems to use one, if it has been enabled before (only for lock).
So, Basics now
AGPS is not QuickGPS. AGPS uses a database stored on a Internet Server.
It calculates your position by using this triangluar method (the cells of your provider) and can dertermin your position
quite exactly, so the GPS lock duration is reduced dramatically.
The triangluar method just tells the device: you're between those three stations, i.e. in that triangle.
QuickGPS downloads a database that contains the Location of the satellites in
your area, so the GPS device doesn't need to check all stallites, as it just can't connect to some.
This reduces lockup time as well, but won't work anymore if you move about 300km without enabling GPS.
AGPS will work anywhere and is more precise. Combining both brings the most effort.
Hope, this helps

how do i put that ip address in? and where do i have to go to turn on both agps and normal gps at the same time

Use a Registry Editor (for example PHM Registry Editor) and go to this key:
"HKEY_LOCAL_MACHINE\Software\HTC\SUPL AGPS"
There's a picture of it in post 2.
Set "EnableAGPS" to 1 and enter the IP Adress in the field "ServerIP", then restart your device.
With "normal GPS", I thing you mean QuickGPS? Just let it download the
desired data and its done.

Yup. My aGPS has been working from the start.

Diewi: you forgot the server port

Please read the explanation of GPS I added to the first post. It clears up a lot.

As explained in the first post this is not necessarily a carrier service but can be provided by your carrier. I did check the settings and did not see it there. Does anyone see aGPS as a service here?

No software needs to be aware of QuickGPS. QuickGPS data is use directly by the GPS reciever. Software all use an API to get the GPS position. How the underlying reciever gets that position makes no difference. Software does not need to be aware. QuickGPS is not the issue however. Please see the first post.
More replies later. My turn to drive.

Yeah, in the Service tab there's something called "Location Setting". I don't have this as
well, but there are many users and howtos report this. I think this just with the
expensive providers and contracts. It seems to set agps up automatically. But I'm happy it works without this.
@nevermind: The port is just the default one: 7275

a-GPS is something different.
Start of the GPS is slow for one reason. GPS has to download orbit data from the satellites. There is one 'rough data' package, that contains data for all satellites and is transmitted from all satellites. It should basically tell you 'which satellite is over the horizon at the moment'. That is also the reason you could enter your rough position in the 'cold' boot process. These days GPS receivers have so much channels, it makes little difference, so this function is not present in most todays GPS units.
Anyway, that is just a beginning. Then you have to download precise orbit elements. Ant those are transmitted only by each individual satellite, only for that satellite. It's not much data, few numbers. But there is no feedback, no handshaking, so if there is some error in receiving it, you must simply try again.
Especially in situation like car moving in city, this process can need many retries. Thus it can take long. You can see the GPS is downloading the data from the satellite for example in Garmin XT software. Downloading satellite has empty signal gauge (but corresponding signal strength), downloaded satellite (can be already used) is displayed with full gauge.
So basically .. you wait because you download few numbers from satellites 40.000 km away with no handshake. But wait .. downloading data .. that can GSM network do much better. And that is a-GPS. GPS software simply downloads the precise data for each satellite from webserver. This process can be controlled in QuickGPS app.
This is done in the GPS driver, so the mapping software does not have to have any support.
a-GPS is different then getting location from GSM BTS stations, which only some software supports (like Google maps).
Also a-GPS can indeed broke your fix, especially on Xperia. Sotimes the data from GSM network are downloaded wrong, or are old, no idea .. but if it happens, you loose signal very often (because unit tries to read position of satellites which are not above horizon) and the position may be off. In such cases: try to manually reload data in QuickGPS, or try to disable QuickGPS altogether.

Ah .. actually I may have it mixed .. and this could be Quick gps while a-gps indeed is location from BTS. But then it has nothing to do with GPS accuracy or speed. It will just give you rough location fast. And as far as my Xperia goes, in google maps it works perfectly.

Alright, I get your point, but from what I know AGPS is "better" than using sources like
QuichGPS. It gets your position more precise. Don't know how it's implemented, but this
seems to speed up lockup time, as many articles state it (and from what I experieced).
Maybe it just "validates" the data sent by satellite. But for me it works even without using
sofware that is explecity written to use carrier information (Meaning speedup).
From what I've seen Google Maps just takes the cell you're into and says: well about 5km there
you are. That's not AGPS from what I know.
But from the basic things you said, you're right.
Basicly I gotta say it works and is better than any other solution. Perhaps an
expert in GPS issues can clear this.
So, as a summary one can say the better the device knows where it is, the
faster the lockup is.
This discussion is getting more and more theoretical, isnt't?
What I advice everyone who is willing to use AGPS is to take the Registry
settings I posted above.
