Nothing helps.
It seems, GPS driver sure, that altitude MINUS 150 meters is wrong and do not return position to OS. But actualy altitude of Dead Sea ~ -400
Now I can't check this issue now
1. I'm on GB now.
2. Point, where GPS lost is about 80km from my home and I've no plans to visit it in near future.
But It already checked 2 times.

Hi. Have the same problem. Below -165 meter, gps cannot fix until you get higher altitude. nothing helps

Today I had the same issue near Dead Sea. No problem with iPhone.

In IOS & Android the GPS is already useless since there is no proper navigation like the one in Nokia phones

What are you saying? There are very good navigation solutions for Android. Sygic, Navigon and TomTom will be released in October.

same here - more info
Having the same issues: below -168M, no GPS fix.
More info:
-Aside this issue, no other issues with the GPS – the GPS function perfectly, locks quickly etc (above -168M)
-Below -168M, the GPS continue to have good satellites viability (at least 5-9 are fully ‘green’), yet the data (location, altitude, etc are frozen).
-The above occurs with all GPS application i tried (several status / navigation apps).
-using other phones GPS (e.g. some Alcatel with 2.3.4) at the exact same locations, their GPS is o.k.
-upgrading from Android 2.3.7 to 4.0.4 did not solve the issue (both cyanogen)
-I tried the "[root] GPS Control SiRF StarIV" app – did not solve the issue
- Planning to try "GPS Aids" app - not sure exactly what it does/will it help...

Didn't try to modify the gps.conf file.
Quick search on the web, seems like most suggestions to modify the file are related to improving the performance (faster gps lock) -not resolving complete lack of locking.
Do you have a specific recommendation/idea what to change in gps.conf file for this specific problem we have? if so, can you please explain
why?
(note that here is no lock performance issue here. its simply completely stop showing position below certain height)

Well, its worth a shot? But before you do, are you using the internal gps or the bluetooth gps? If your using one, try switching to the other?

I tested a GB ROM 2.3.6. It did not loose lock if coming from a high place, bit when I was already at the dead sea and opened GPS Test, it did not lock again even with 12 satellites in view and with good signal. I believe it is the GPS chip Firmware that causing the problem, so there is no fix for it.

This doesn't belong in the development section, and you should use the search function.

Thanks, NOsquid
I tried the listed instructions with little success. Then I tried the "warm start" selection and get very quick locks with more satellites in use than ever before. Ill try navigation and see what happens with continuous use.
Yeah, just keep testing for yourself. The problem allegedly is one of improper caching so the warm start may end up screwing you - see satellites but not lock. The cold start may take a little longer, and you need 3g.
Allegedly
I don't know if this is relevant, but there is an app called gps booster that really works in less than ten seconds to acquire a lock on gps. You may want to check it out...
It's legit because algorithms are used to estimate gps satellite locations.

Maps and Navigator trouble... =\

Hi guys,
Well... I have installed recently CM7 6.5 and Kernel 18.1. I changed the kernel version (to v18) because of the big battery drain and i can't use Maps and Navigator!
I don't remember if i tried it with Kernel 18.1, but when i open these apps, they keep loading, and loading, and screen's light turns off and nothing... they don't run!
I have tested other apps, and they run normally, the trouble is in these two apps...
=\
Someone have a solution?
Obs.: I have installed street view too and i don't use 3G.
Thanks!
Nobody knows about it?
Please, someone! Help me!

I reflashed maps application and for my surprise, the app run normally, without any problem... maps and navigator.
Well... i closed the app and when i tried it again, a problem appeared. I can see only the last map charged... if i search for any adress, it keeps charging, and charging, and the new map doesn't appear. In the navigator, the app can't find my location...
What curious case! Anybody knows what i can do to fix it?
Thanks!
Obs.: I can reflash maps several times and it works until i closed it, after sometime running the app.

You need a WORKING DATA connection, period. You can prefetch some 10 "maps" (IIRC 10 miles diameter) in latest versions to avoid that.

AGPS Patch - Need some testers for Official support

Well, my goal for the upcoming v2.0 of my aGPS Patch is to bring support to five more devices. This is one of the devices I selected!
I'm looking for some testers to see if the patch will effectively work.
It simply replaces gps.conf in /etc/ to be much better performing.
You can download v1.3 by clicking here.
To install, use Root Explorer or ES File Explorer to copy the new one over. Reboot. Give GPS a try! I recommend GPS Status. If your device uses ClockWork Recovery, you can simply flash the ZIP.
A reference thread can be seen at http://forum.xda-developers.com/showthread.php?t=1250226.
Also, I'd love for someone to send me the gps.conf currently on their device.
Thank you for assisting me in the determination if this version works.
Attached is the gps.conf in my P500. I'm not sure if it's the same as original gps.conf in LG's stock ROM, since I'm currently using a custom ROM (andy572's Phoenix with Gingerbread 2.3.4), but IIRC Andy didn't tweak the gps so it might be the same.
I can't flash the zip (using AmonRa recovery, disabled verification) but I'll try using File Expert to put it in /system/etc/ later.
I've had word a week ago it worked swimmingly with this device...
Look forward to your results.

i think gpsconf is better in noejns void froyo final
I've changed the gps.conf. Nowhere near an rigorous test, but my results using GPS Status are:
Before - Fix in 112s, 5-6 satellites, didn't note the error
After - Fix in 28s, 7-10 satellites, error 5-10 m
Seems to work. Will try your note #2 and test in more locations later.
Do you think it'll do any good if I add my country-specific server (id.pool.ntp.org) to the file?
Will test tonight
I've attached my gps.conf; I'm using default 2.3.3 with only a custom kernel. I haven't used gps since upgrading to 2.3.3 (used void. before, there gps was really snappy)
However, can you tell us how we can test with gps status? I can't really tell when the gps gets a lock...

Country specific NTP servers aren't necessary at all. Your device should get an NTP server near you and quickest for you from the NTP pool by default.

Well, open up the app once it's installed. Let it run for a few minutes and let the GPS learn about its fellow satellites near you. You should see 5-10 satellites depending on your location. After that, exit the app. Reopen it after a few seconds, see how quick the lock is. Further, you can see the Error accuracy on it as well.

Kind of a new newbie question. What do you guys have on, to lock in your locations? When I have data or wifi on, I get lock in seconds but when its off I rarely ever get a lock. GPS should work without having to have data or wifi on. I'll help out with the testing.

Gps will work without them yes. But agps will not. This will use agps data properly with ntp time servers to obtain a quicker and accurate lock.

Once all the data boxes on the app are filled in with data obtained for your location, you know you have a lock.
Also, once it looks it will flash a message at the bottom in the center saying the lock time. Mine will flash like 3 secs. But it won't stay on the screen but of another second or so. That's why I say see data filled in...

Okay, so do you prefer test data with or without agps? I'm asking because with agps I get a lock very fast even with the standard GPS conf...
That is, between 5s and 12s...
At least it isn't negative. So I think it's releasable because it can help users with problems. Any opinions on that viewpoint?

Use a testing app like GPS Status from the Market. Or, open up Maps when you're outside and see if you get a quick lock on where you're at. First time takes a bit and that's why I recommend GPS Status to let it "learn."
The flash failed for some reason. It said there was an error. So I tried to just replace the file using ES File Explorer, but it would not allow me to replace or delete the existing gps.conf file. I'm not sure what to do...?

There seems to be a tradeoff for me. I'm getting a higher error with your gps.conf, but I get the first fix instantaneously (fast enough that GPS Status doesn't bother to report the time) vs. ~10 seconds with the gps.conf included in my ROM. Both of them were able to lock on to up to 10 satellites, but the error was definitely lower with my original gps.conf.

i've just posted in mik's rom discussion thread:
sometime ago i posted here about gps problems. people were facing the same problem: not getting any satellite in view after first use of gps. clear/update agps solved the problem, but only for one following try.
then, i replaced my gps.conf file for this: http://forum.xda-developers.com/showthread.php?t=953630
i downloaded the one for brazil (my country), that was on his server. fix now is very quick, even though sometimes my accuracy is like 2km, but under 1 minute it's normal again (5~15m).
also, i've noticed sometimes it gets a fix with not even one satellite in view. this causes a huge offset in my position (imagine being in germany and your gps telling that you are in UK). but after a clear/update agps the problem is gone.
give it a shot.

[Q] GPS coordinates where?

Hi, where can I find the GPS coordinates in the stock GPS app? I don't want to send anyone just read from display.
Get yourself something like Ulysse Gizmos from the Market.
Can report DMS, UTM, etc... a few different heading/bearing options as well, and updates your AGPS data each time you launch it. It works with Maps as well, so you can see where you are on the map as well as knowing your actual XYZ.

Android GPS Problem

Hi, does anyone know why my car android system GPS is showing an incorrect time please? I have the android time and zone set to manual +1 BST. The picture shows the GPS Test app with the UTC and local times completely wrong to the actual time in the UK.

Could the GPS is taken it's time from the gps sat instead of locally set time..

I have checked my android device and I don't have this gps.config file. Anyway, I have tried a number of sat nav apps and they all seem to work off the local time. The Tom Tom app seems to always show an arrival time 2 hours behind which is what prompted this original post.
I prefer the tomtom app which is why this issue is annoying. Any more suggestions?

Did you check the tomtom forum?

I have been on the TomTom forum and had no joy there.
Maybe your device take it's time coordinates from the radio, like RDS.
Or it's just not supported.
Edit; disconnecting the satnav for an reset seems to work on some devices.
Sent from my Lenovo A820 using xda premium
That appears to be an Enco / EWay device, possibly for an e46. I have an Enco B046, which presents the same issue. The UTC time reported by the GPS is incorrect, and is actually off by 14 hours on my system. TomTom uses the time from the GPS to determine your time of arrival. Nothing like going on a 1 hour trip, leaving at 2PM, and having TomTom tell you you'll arrive at 1AM.
I'm pretty sure the GPS driver is poorly-written. It doesn't report location accuracy, which is why Google Maps / Navigation will not let you use Turn-By-Turn (driveabout) mode. Google Maps looks for ACCURACY_FINE to be true, which is defined as...I can't remember, but like, 40 meters accuracy or less, or something. The GPS driver on these units reports null, or possibly 0, depending on how it's extrapolated, for the location accuracy.
It's a system called Andrive which is very much similar. I think the firmware is faulty which the supplier is looking into although very slowly.
