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.
Regards
Phil

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:
http://forum.xda-developers.com/showpost.php?p=1650269&postcount=31
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?

Question about TomTom & its icon

iv just downloaded the latest tomtom, and its put a badge/icon on my today screen. AFAIK it doesnt actually do anything, it cant be clicked on or selected, and as a result id like to get rid of it.
iv tried going through the Tomtom settings, checking the today\items and deleting it from the registry under software\microsoft\todays\items but none of it gets rid of it.
Does anyone have a way of doing it?
cheers

You need to *uncheck* the Tomtom box in the today screen options and that icon will then only be accessible from the start menu. Thats what I did with my TyTN II and it works perfectly. If the box is checked you'll get that icon on the today screen.
BTW, if you're using the recently released HTC WM 6.1 update with HTCs Navigator 6.032 are you finding GPS performance to be much worse than before the upgrade (slow fixes and wild fluctuations in GPS reception bars even when stationary)?

thanks for the reply, ill give it a go.
Im a new tom tom & 6.1 user (just flashed one of duttys), so dont have any previous experience to compare it with, sorry.

I'm finding the Tom Tom (and other GPS apps) to be worse after the upgrade unfortunately - it's the only fault I can find with the new ROM. The problem for me is just the first fix after any soft reset - it always takes an age (up 10-15 minutes) which I'm sure wasn't the case before.
Subsequent fixes (after closing and later re-opening TT or another GPS program) are always much quicker, within 30 seconds even, so obviously once it's been initialised once it's fine, until the next soft reset when you're back to square one.

do you download the quickgps data after the soft reset, i believe that doesnt save when you do a soft reset, and the first lock you get from GPS, will be remembered and make it easier for the future connections.
I never have a problem with GPS connections, only tomtom and its poorly slow application refresh.

AFAIK it downloads in the background on a regular basis still, whenever I'm plugged into the PC at work (which is most of the working day) - whenever I check it, it always claims to be up to date, anyway. But I agree the behaviour is as if that data isn't there anymore... peculiar.

Then you're lucky! Mine now locks up regularly (2 or 3 times a day) and it never used to before the up?grade.

Although this part also applies to me, even after getting a fix, if I shut it down while I'm moving and start it up again after a couple of minutes its still much slower than it used to be in the same locations under WM 6.0
I'll email HTC and Tomtom about it as it's clear there's now a problem.

If you ever used HardSPL (or possibly even if you didn't) you probably need to flash the new HTC SPL - see the thread over in ROM development. It cured all the freezing issues for me.

I'm pretty sure it's an HTC issue, since I have the same problems using GPS in MS Live Search too. Unfortunately there's not much point in me emailing them, because mine is officially Vodafone branded and they don't support it.

Thanks for the tip. I'm the old school sort who believes the hardware provider should be responsible for fixing things, hence why I'll write when I get the time but I may try this later if I get annoyed enough! I've never installed HardSPL and this official HTC upgrade was the first flash I've subjected my TyTN II to.

In the end the buck stops with HTC and as they are responsible for my phone, I'll remember other branded users are also depending on a fix from them when I write.

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 expand...
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.

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.

Problems with GPS

Google Navigation is constantly giving me the "Searching for GPS..." message. Even when I use other navigation programs I still get the same message and the same blinking GPS icon in my status bar.
I have tried a number of things:
Flashed a new ROM (went from Cyan's latest to Dwang)
Reflashed the radio
Flashed the Danger SPL
Flashed Amon RAs Recovery
Nothing worked
There was a time when it worked, but that was a few months ago and I don't remember when it stopped working.
Just so you know I have tried it outdoors on a clear day, and I have reinstalled Maps many times.
If anyone has any ideas it would be greatly appreciated.

Try downloading the GPS status app from the market and see how many satellites your receiver can see. it needs atleast 4 for a good lock, at minumum 3. If your receiver can't see any, it may be defective

It cant see any.
Could something like flashing a ROM cause the GPS to become defective?

not likely. are you inside a building when doing this? I seem to recall way back when I first got my G1 in the preorder that we were told to properly calibrate the GPS by going outside, turning the GPS on, setting the phone down for 5-10 mins somewhere that had a clear 360 degree view of the sky and let it go to work. I did exactly that. Over a year later and it takes my GPS less than 10 seconds to drop to a 3m radius, unless I happen to be in a building, and even then its pretty good (I can generally get a 20m lock inside thick buildings like shopping malls, etc).
So give that a shot and see if it calibrates.

Well I left the phone outside for a solid half hour, and it still isnt finding any satellites. Any other ideas?
*EDIT*
I realized what is wrong. A few months ago i PEELED OFF THE GPS ANTENNA!! I just thought it was pointless tape on the back and it was already starting to loose its adhesive, so I just pulled it off. I feel like a grade-A moron.
Is there any other material I can substitute, or any way I can repair this?
