GPS messed up

Someone help if possible! My GPS on my Tilt was working perfectly with Google Maps and LiveSearch... but today i turned it on and it's locking onto a position about 500+ miles away. I have VisualGPS installed and it now is only locking onto a max of 3 satellites (but sees many more satellites) when it used to lock onto about 6+! It also thinks i'm at 57,000 feet and somewhere over the gulf of mexico when i'm currently in south carolina on a trip! I tried soft resetting about 5x and ran QuickGPS a few times as well... nothing has fixed it. Any suggestions?

did you install anything new or do anything major like settings or drop the phone?

Nope...it was working fine one day, and not working the next... phone wasn't dropped and no new software was installed and no settings were changed. Not sure if the chip is malfunctioning or not...but it does lock onto a location... the wrong location.... but it is consistently putting me in somewhere in alabama at the moment

Hi UTZorro
I can't really help you with your problem but I did notice on mine the other day that the satalites would drop in and out quickly and never lock onto more that 3. It was a very clear day with clear view of the sky. The co-ords were out by quite a long way because of it. The DOP was never very good. I restarted and it seemed to solve the problem but it wasn't a good sign. I know I hadn't dropped mine and the quickGPS data was current.
I also noticed that the voice in tomtom was all over the place.. I had to reinstall tomtom to fix the problem and put the voice on the main memory. At the time I thought it might be my 4GB SDcard but now I'm not so sure.

Hi
Have you tried leaving it on for several minutes? GPS on these sorts of devices make several assumptions as they try to lock on quickly so you don't have to wait, sometimes that initial lock is wrong due to these assumptions. Either turn it on and leave for it around 10-15 minutes in clear view of the sky or try running QuickGPS, that may help.
I've had this happen now and again, just leaving it for several minutes to get a "proper" fix and all is well.

I saw the same problem, i was driving and according to my gps i was going 485 km/hr and i was "flying": above the sea. kept the copiliot log as thought it was funny
I rebooted my kaiser and it went back to normal

This randomly happens to me also on a Stock HTC rom. Not too often though so not a major problem.
Reboot fixes it ...

I had the same problem last week. I Soft reset the device and removed the battery before it booted back up. After about a minute I put it back in and it was OK again.

happens to me as well, soft reset solves the problem... also if you have your GPS app on your SD card removal fixes this as well, very peculiar problem

I second this: I had strange behavior after a lockup and it took several tries with 10minute or so open-sky accesses to clear up:

Go sit on a park bench for 15 minutes or so with the GPS on and open in an app which shows the satellites in view - like TomTom/Mapopolis/whatever and see if you don't eventually get back up to the 7+ birds you normally get.
Good luck!

recently this error has been happening more frequently to me with TomTom, restarting doesnt seem to fix it all the time anymore... does anyone know what causes this? It constantly showes me somewhere in Ontario, Canada about 500 miles from where I actually am.
Is there a way to disable and re-enable the GPS chip via software similar to what a hard-reset does but without the 30 seconds+ downtime associated with the hard-reset?

This is being caused by Quick GPS. If you have not connected to the internet via Activesync for a while then when you first start your internal GPS or lose sat coverage it diverts to the last stored Quick GPS data for the most prominant 3 sats (they show up as full signal when you look a gps data in you mapping SW) that should be in your area.
Either sync at least every 5 days (on a PC with T'internet connection) or disable quick GPS and be patient for a lock.
Hope this helps.

Hi
I had the same problem, but it seems I found a solution.
I'm not 100% shure, but for what I remember I had this problem very often. like every time I was starting navigation it was wrong, so I had to soft reset - Everthing was fine - till next time when it was wrong again - and soft reset and again, again and agian.
It was so annoying - then on a Polish forum a guy wrote somethign about downloading quickGPS data (what he read here) and quickGPS was the solution, but for me it was to disalbe every sync function - because I set to sync evertime it was possible I believie that was it.
Now I'm using kaiser for about a week and testing it 2-3 times a day. and it never failed. I'm not 100% shure it was it - but it looks fine now.

So after a few days after I originally posted with this problem, it noticed it had spontaneously fixed itself after my flight back to town and I pinpointed what fixed it. (keep in mind i have stock Tilt Rom, QuickGPS was updated at the time (about 25x to be exact) and I had even hard resetted and it didn't fix it)... but here's what did fix it interestingly enough:
So, for some reason, if you have flight mode enabled on the phone, then you turn on the GPS (which I admit I did while bored midflight wondering how high up we were) it MAY get messed up like what happened to me. The only way to fix it is by putting the phone back in flight mode turning the GPS back on and then turning it off again and re-exiting flight mode. I have no idea why flight mode and the gps would be related in this siutation (it makes no sense to me)... I didn't believe it myself until I repeated this experiment twice!!! So, i'm posting this for reference to anyone who may have the same problem in the future if their phone was in flight mode and their GPS got activated and then subsequently messed up! Any thoughts?

problem with gps?

is anyone else having massive gps problems?
tomtom is setup correctly to use the internal gps but it either tries connecting forever and getting nowhere, or it eventually picks up 1 satelite and thinks im in canada..
I've just put on dutty's rom but was having problems before also.
any ideas?

If you read the instructions...
You have to run GPSTEST first, to lock on, then minimize, then tomtom

Try it outdoors. No, really!
Been playing with TomTom for the first time today. Tried all day at work and it wouldn't work - kept coming up "No GPS Device" at first then switched to "Waiting for Valid GPS Data" or something. Anyway, kept trying with QuickGPS on, put the phone by the window, come back 10 minutes later and still "Awaiting". After 2 hours, gave up. Tried switching the TomTom on in the car on the way home, and within a minute it was happily directing me home (correctly).
Turns out the best advice I've read is "USE IT OUTDOORS OR IN THE CAR." I just thought I knew better and that a large window on the 3rd floor was just as good. Turns out it's not - and I'm an idiot for thinking I knew better than the experts here!!

I have no problem using the GPS inside my apartment sitting on my couch.

GPSTEST just sits with "GPS starting up"..
and like I said, I was having problems before duttys rom.
its absolutly pissing down outside now so it could be that.. but I havnt been able to use tomtom for a few days (including out in the car) so any other ideas?

Are you using the version of TomTom that supports the internal GPS? because if you aren't it won't find the GPS signal.

yes, and I have it configured to use it correctly.. (com4, 4800bps)

so it seems it might have just been the ****ty weather and me being indoors... its all good again

you dont have to minimize it, you can run, lock in, and then close it, then open TomTom...
Also, do not, i repeat, DO NOT play with the external GPS configurations, it can permanently mess up your GPS, and only way to fix it is hard reset...even if you put the settings back to default, it will mess it up...i remember reading this info on the forums, im sure it still applies...but ya said its working so good for you!
oo and also make sure you dont cover the GPS antenna in the back or you will lose signal or get weak signal...

GPS Problem

Yes, I know, another GPS thread. Not ideal, but search won't allow 'GPS'.
Plus I have searched 'manually' through alot of threads but to no avail. I still have a problem with my GPS. Basically, I can't get any GPS reception. I've tried different ROMs, radios, hard resets, soft resets, updated QuickGPS, run GPS Test, taken battery out, everything I think! I just have nothing. On GPS Test, all I have is a screen showing:
'GPS Starting Up' (Fix 1D, HDOP 0.00)
It just stays on that screen FOREVER. I'm beginning to think I might have a hardware problem.
Can anyone suggest any ways to test the GPS further? I know it's a pain having another GPS thread, but I really didn't know what else to do.
Hope someone has some sort of solution.
P.S. Note to mods: maybe enable 3 letter word searches? Some words are crucial, such as GPS, sim, etc.

In the gps settings on gps test have you changed the baud rate to 4800

Click to collapse
yes. i've tried all the baud rates just to be sure. I also get no response in Google Maps. Just nothing. It's detecting that I have a GPS unit integrated into the device, but no signals are being picked up. Does the fact GPS Test is stuck on 'GPS Starting up' signify anything? It seems strange it doesn't say 'Cannot connect to any satellites', or something similar. Or is 'GPS Starting up' the same as saying that? I'm just totally lost.

I should have said, I have been trying this outdoors as well. Not indoors.

Now, this is an extremely long shot. I just checked my battery and my phone. My phone is marked (under where the battery would be) as a DIAM100. The battery is marked as DIAM160. I've seen on the forum before different numbers like this meaning different things, and also different batteries creating GPS problems. Anyone ahve any idea about this? It's so frustrating!

Well to answer your question above my phone also states its a DIAM100 and the battery also states DIAM160 and my GPS works flawlessly.
I dont really know what to suggest to you.
Hope there is someone in this forum that can help.
Good luck

Clean install, QuickGPS data, then run GPS Test...
When you are running GPS Test after a clean install with updated data from QuickGPS only do you get any bars at all? Typically you start with nothing, then yellow bars pop up (and disappear....) eventually turning to green. Need at least 3 green bars to get a decent fix....

I'm not getting anything. It just stays on the 'GPS Starting up' display. No bars, nothing.

I has the same problems with setting up GPS after flashing with various ROMS. The answer was found within these forums, can't remember who but credit to you, simply back up your settings and hard reset. After I did this GPS has worked flawlessly getting a fix in under a minute. Hope this helps.

Forgot to mention AGPS is turned off using Advanced Configuration, available from this forum, and using CoPilot 7.

I've already Hard-resetted multiple time on multiple roms. I'm just getting nothing. AGPS is already off too.

Flash with another ROM... hard reset after FLASHING.... and then start HTC_GPS_TOOL

Last resort, then warrenty return I suspect
If it has never worked since new then it sounds like flaw with the device, and perhaps a return to store...very unlucky. Last resort might be to change your Hard-SPL but thats getting desperate

What should I be seeing in HTC_GPS_TOOL? It is all very confusing. Lots of numbers and stuff. Seems to be repeating a five line sequence. Doesn't seem to be linking to any satellites.

With HTC Gps tool you can make a "cold reboot" of your gps. This means it removes any data in the gps. - Do that, go outside and wait for 10 minuttes. This usualy works for me.
You can get the gps tool on my homepage www.maritime-billeder.dk/htc-diamond.html

Could you possibly give me a step-by-step process of making the cold reboot? Thanks.

Using HTC GPS Tool (latest version best), in the menus select Q7200 for chip, 4800 baud, and COLD restart of GPS....have you had this issue from new? Has the GPS ever worked on your device?

Nothing was working. Getting a new handset from Orange tomorrow.

GPS same problem
evilskanker, I have exactly the same problem. the user "pietrucci" on this forum also sent his device for repairs as nothing helped, not even flashing everything back to stock.
this is SO frustrating and if I can't get it to work I'll never flash any **** like this on my device again.

Which version is the latest of HTC GPS Tool, I was supprised to see you have chip model selection which I don't have. Mine is exactly looks like this one: http://www.youtube.com/watch?v=wOesPtnXP9o
Is mine the old one? No wonder I couldn't get cold start working.
But how come the version you have doesn't have "clear memory" option?
I'm going to give a shot with your version tomorrow since it is too cloudy outside tonight.

Tilt / AT&T stock 6.1 ROM and GPS issue - kills radio

Here is the situation:
I have the aforementioned phone, bloatware not installed. A couple of days ago I tried using Live Search's GPS function and could not get a lock. AFter that, I had radio issues - icon would switch from E to G to H then show no signal. Spent a majority of the time in the no signal mode. Soft reset, restore using sprite backup, even a hard reset didn't clear it up. Resorted to re-flashing the stock ROM, which cleared the problem. Every time I try using anything that turns GPS on (HTC GPS Tool, TT7, Live Search) I end up with the same problem, only resolved by re-flashing the ROM. And, of course, calling AT&T and asking their "tech support" anything that is actually technical makes their little brains overheat. Seems that they have no idea about doing anything with the GPS other than running TeleNav.
I have not found any posts describing the same problem. I don't know if it is the radio version that is the culprit (1.65.21.18), or perhaps a faulty GPS chip, or what. Perhaps it is time (especially since the phone is no longer under warranty) to either find a cooked ROM (of which the selection is endless) or venture off and make my own (something I currently just don't have the time to learn).
And one other thing... while flshing the third time, the progress bar reached 13%, the phne went back into bootloader, and the SPL number changed. When I started flashing it was 3.56, and after the 13% glitch the SPL showed as 3.02... seemed odd...
Any insight into this is greatly appreciated.
If anyone has any insight into this, it would be greatly appreciated.

I believe this thread is discussing this issue: http://forum.xda-developers.com/showthread.php?t=397728
I've been having the same issue as well. The long thread I linked doesn't give much help. The majority of the answers are "use a cooked ROM" - which i'm not interested in.
The other suggestions are to try another program like Quick GPS, and a program called GPStest. Not sure 100% how you use the GPStest to help it, but I boot it up along with Googlemaps when I need a signal.
I've found if I stay still (not moving in car) I can get a lock somewhere between 2-15 minutes - it varies a lot. However, after a cold lock (no soft reset) my connection times are less than 30 seconds.
But I feel your pain - it can take a very very very long time for googlemaps to connect.

Sorry, the issue is not that it takes a long time for GPS to get a lock, it is that it screws up my radio - after activating GPS with any program, my service goes to hell.
As for a cooked ROM, I would rather learn to make my own so I can get it just how I like it, but I barely have the time to scratch myself anymore, let alone start fiddling with that.

Oh sorry, I am guilty of skimming your post.
But on a side note, you should really make time for scratching yourself - It's a necessity that really should not go ignored.

TomTom Not Finding Satellites

For some reason TomTom7 is no longer finding any satellites after upgrading to EnergyRom 3.0, 052809 version. It worked previously, and both Google Maps and GPS Test are still able to see many satellites in only a few seconds. But TomTom is picking up nothing but the AGPS signal, which only updates every 5 seconds or so. Anyone have any fixes or settings to try to make it work again? Or should I revert back to the older rom that worked previously and just make due?

I've had same issue...I found that it just doesn't show the constellation...if u just "trust" it and wait a few minutes it will catch your position and it will be able to navigate even tough it still doesn't show any sattelite...hope this helps

Alrighty, maybe I'll take a long drive today and see if it picks up anything after awhile. It was working so great earlier in the week with the old rom, I'm mad I just didn't leave it alone.
It gets something even though there are no GPS satellites being picked up, but it only changes my position every few seconds, instead of a couple times a second like it was doing. I assumed this is the AGPS, but I'm not exactly sure what that does, so perhaps not.
But, thanks for the help.

Mine doesn't seem to show a signal anymore, but it does work. Like what was said, just give it a try and trust it.
