Tilt GPS VS SIRF III [pics]

I thought I'd do a signal comparison with the new tilt. I used TomTom gps viewer for ease of use.
Here are my results.
Patio area:Fairly covered, narrow view to N and E 45* at best, mostly 80*ish
SIRFIII

Tilt on Patio: NO FIX
Next I went to the car. Its in parking lot surrounded by buildings, about 45* clear on 3 sides, 60* on one side....
SIRFIII At sunroof
Tilt at sunroof
I used the sunroof because I typically put the SIRFIII receiver in the sunroof slider for best signal, this is obviously not possible with the tilt so I also tested at the console...
Next post....Pic limit...

SIRFIII at console
Tilt at console
Notice the Tilt at sunroof is nearly = to SIRFIII at console...
Now I tried one to test the SIRFIII's capabilities.
Inside garage with door closed on bottom floor of 3 story building on the console....
I couldn't believe it still got a fix on there, I'm amazed
And of course
Tilt in garage on console...NO FIX (duh)
If anyone else has results/input please do add.

I am inside the building, and still get result!

Same here. =/

me too. I get no fix inside my 2 story house with no trees around. I lose fix even inside a train that is travelling through a wide open area.

2 stories above me.
For me it basically works every where I have tried. Locks under 5 seconds. Used to have the Ipaq 6945 and took almost a minute to lock and never got a lock inside buildings. I do know know how well this compares to external ones since I never got the chance to try any. Overall very satisfied.

I have never got a fix inside a room and I think this is quite obvious.
And basically I dont really care, why do I need to use GPS inside a room?
The thing that really important for me:
- How is it perform? Do you get signal lost quite often?
No, I dont. I have the same experience when using my old Magician+BT-338 Sirf III external GPS.
In some rural area in Belgium I noticed the Kaiser GPS has only 1 bar of signal, and it worked fine.
- How fast is it to get satellite fix after exiting a tunnel?
Again, same experience with my old SirfIII GPS.
- How fast is it to get the first satellite fix after turned on?
Very fast, between 5 - 30 seconds The same experience with my old SirfIII GPS.
Well, at least, thats my own experience.
For sure, SirfIII GPS could be more powerful than the NMEA of Kaiser, but the NMEA is powerful enough
At first I was quite skeptical about this NMEA vs SirfIII, but not anymore.
Next week, another test ... 450 km driving to Germany

I find my Kaiser VERY slow to get a lock. Even outside with no obstructions. More than two or three minutes in most cases.
I'm comparing to a Garmin Nuvi 660...
Only software I have tried is the GPS photo and Google Maps.

The Kaiser GPS is A-GPS, meaning it can use mobile phone signals to aid a fix.
Personally, going from a bluetooth sirfIII to the kaiser GPS, I don't notice a difference in accuracy in day-to-day usage.
Fix time, however, with the Kaiser, is much, much quicker. 5 seconds max usually.

Have you updated the GPS quickfix software? This downloads the satellite positions in advance so that it does not have to download them from the satellites, which is low bandwidth and subject to interference. Even if you could see every satellite, you won't get a "lock" until it knows where the satellites are and can do the triangulation.

I have always been able to get a fix inside my living room. The only place (inside) where I have not been able to get a fix is at my workplace, but, then again, I don't get cellphone signal at workplace either.

It seems we either had a poor experience with it, or a great one. I'm using the ATT ROM.

AGPS (Assisted GPS) is disabled in AT&T's ROM. Can someone with the HTC ROM check HKLM\Software\HTC\SUPL AGPS\EnableAGPS?
On the AT&T ROM EnableAGPS is disabled, or set to 0 and the GPSMode is 2. What are these values on the HTC ROM?

Seems Assisted GPS are disabled in HTC too. Can be enabled changing the EnableAGPS?
What are the advantage of using instead of QuickGPS?
Thanks.

AGPS will help get your location using the cell network. I will enable it and see if it help getting GPS locks while indoors.

Did it help at all ? Very intresting

It did not help at all. The server configured in the registry is for Orange in France. Unless we find one server that works for us in the US, I don't think we can use this feature.

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.

gps
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

WM 6.0 ROM/Radios give better GPS performance

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).

Are you sure about that radio at that stage? 1.65.xx.xx series radios are meant for WM 6.1
- 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

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!
Kiwi, thank you very much for your elaborate reply!

Yes, thank you for that thread, it comes pretty close to confirmation.

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).
