This doesn't belong in the development section, and you should use the search function.
Not sure what they did for the Vibrant, but you can try what's in post 81

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.

Hey I have looked around some is there a gps fix for the Fascinate?
Sent from my Nexus S using XDA App
Heh, didn't know it was broke.
good day.
GPS Aids v2 from the Marketplace fixed GPS for me and a few others that I know of. Run that once and check GPS status within the app. Ignore what it says about XTRA not being loaded/installed correctly.
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.

Did you actually try this one? Or are you just stating that?
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.

Hi was wondering if anyone has similar problems to me with the GPS not getting a fix. Most of the time it functions fine with Google navigation but there are times like tonight when it cannot get a fix. I downloaded the GPS status app from the market which showed only a couple of satellites where visable and it would lock on to any of them. I then went in to the tools part of the app and reset something called a-gps data (whatever that is?) Then I clicked the download link and it received some data. After that the GPS got an instant lock and has been fine since.
I just wondered if anyone else experiences these problems and if so how do you fix it. My nexus s never had a problem getting a fix I'm just curious as to why I'm having problems with this handset
Edit to say I updated to the latest maps yesterday so I wonder if that has anything to do with it?

this thread.
helped a lot of us out. agps is assisted gps iirc. instead of doing calculations itself, your phone downloads data instead (i think).
Thanks ill have a look at that thread. Seems to be working well for the time being but for how long I'm not sure
Sent from my GT-I9100 using XDA App
makes a world of difference. get a lock within 5 secs normally as opposed to upto 5 minutes!
just remember, if you flash a new rom, the conf file gets replaced. i was convinced that the rom i was on was causing poor gps until i replaced it with a backup off my sd card
So does this require root tommo? I haven't had chance to go through the whole thread yet as I'm not at my computer. I'm not rooted so would have to go through that procedure too
Sent from my GT-I9100 using XDA App
yeah, you need an app like root explorer to get access to the "etc" folder where the gps.conf file is.
very easy to do mind.
Thanks buddy ill give it a try once I get home

Does anyone know a way to keep GPS running when the phone goes to sleep? There are times when I want to have my location continuously reported to Google Latitude, and it's a terrible waste of battery to keep the screen running just to do that.
I'd thought there would be an easy answer to this, but I'm not finding one. There's a two-year-old XDA post on this question here without any real answers. And I found a post elsewhere that suggests that Tasker can make the phone keep GPS working when the screen goes off, but I don't see any function in Tasker for this.
Does anyone have any ideas?
Thanks, Alan

I found Tasker sucked the hell out of my battery, but nevermind... It depends on the app some of them will just pull GPS data when it is asked for, which im sure Latitude would do... What are you trying to achieve exactly?
EDIT: If you do try Tasker you can set it so certain apps will activate the GPS and certain screen times, hours of the day etc...
Thanks! I'm trying to find a way for Google Latitude (which I think just runs within maps) to record my path via GPS (say when I'm on a hiking trip) without the screen needing to be on constantly, which is the only way I've found to do that so far. But if you are saying that I can make a tasker profile which will tell my phone to keep the GPS on when Maps is running, then I think that would solve this! Or do you have a better approach in mind?

Sorry to bump this, but I thought you might like this better if you want to keep your GPS receiver always on when your screen is off (will drain your battery of course)

GPSTracker Lite, specifically made for what its name is. It tracks your path. I use it in my car, in which case the phone is always on the charger when this is running.
Hope this helped.

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.
