I know there are MANY threads to the GPS issues and I am not having problems with GPS lag. I have searched and read and already have the tweaks installed (running the Elite rom rc2 which already had all the tweaks setup) and changed the no data sleep timeout to 1.5 seconds. I also tried on my original radio version, 32 and now have 28 and see no difference in GPS lock times. It will never lock on using Google Maps or iGuidance. In google Maps it says "seeking gps satellites (0)..." for about 5 min then says your gps receiver is having trouble tracking satellites etc. The only way I can get it to work is to use GPS Test, let it get a lock which usually take 5-10 mins, then close GPS Test and open either Google Maps or iGuidance and it will then work fine.
What is also strange is that when using GPS Test, the only way I can get it to work is to have the GPS info set to auto. It will scan then find the gps on com port 4 and 9600 baud. Then it will start up and try to lock on. The next time I run it it will already be on com port 4 and 9600 baud but won't find the gps device. I have to set it back to auto, and restart GPS Test, then it finds it.
There has GOT to be a way to fix the gps lock time on this thing. I have tried with A-GPS on and off and tried with quick-gps and saw no difference in lock speeds. Interesting thing though, I guess Google Maps will using cell tower location to identify where you are? When I use it without gps being turned on, or while it is searching for satellites, and I click "my location" it gets a fairly accurate location on the map.
It seems to me that the issue is with the com port and communication. Almost like the gps won't come out of sleep mode or something and gps test is the only program that can "wake" it.
Thanks for any info.
I am in the exact same situation as you. My TP fails to lock satelites 98% of the times i try.
I have read everything posted about TP GPS on this forum, i have tryed most ROM's and almost all available radio's, i have tryed most tweeks and all that in different set-up.
And after all that my GPS lock's rarely (2-5% of the times i try), and most importantly it doesent seem to be related to the radio nor to the ROM. At this moment i tend to think that i was unlucky with my TP that perhaps is from a lot of TP's with retarded GPS module.
From the forums it seems that most of the ppl dont experience this extrem problem with the GPS, it seems that most of the ppl around only experience laggy gps module update.
Atm i am still waiting for Elite RC3 hopeing that perhaps they'll bring a new gps driver, that will solve my problem.
In case Elite RC3 doesent help i will revert to stock hard-spl/radio/ROM and ill take it to the warranty service.
Sadly this problem with the GPS from my TP blackens my experience with it.
Are you guys sitting in your homes trying to get a lock? because then it is very unlikely you'll ever get a lock.
I have to go outside and wait about 1 minute to get a lock and then its fine. However, I DO have to use the HTC gps tool to get a lock before I can use google maps or any other gps program.
I am outside with no obstructions. I did find this app and may play around with it. So far I havne't been able to get it to get a lock unless I use GPS Test first.

My Telus Touch Pro locks in 3-5 seconds every time after modifying the GPS and adding the correct IP settings for Telus' AGPS. This combined with OCN8 makes for an excellent GPS device.
The guide for the GPS hack was from this forum, just can't recall where.
I have the same problem with GPS Test as you all described. I am now running qsqa's PROven ROM and I noticed following: GPS Test often fails to start-up the GPS receiver, but VisualGPSce worked every time I tried. It is a free software, included in the PROven ROM. If u use a different ROM, you can download it from here: http://www.visualgps.net/VisualGPSce/default.htm
Give it a try, it sure helped me!!!!
How to fix the gps on the Samsung captivates GPS.

This does nothing. It makes it marginally better at best (read: not better at all). If you're really having that much trouble, flash to KB1 and use the PlumbBob GPS fix. Those ACTUALLY do something.
For most your suggestion will give them the most lag and least accurate GPS positioning.
I suggest you in stall Adams GPS fix to your phone, that or use ga_D's. (gadnarf_gpstweak_att)
Both are much better than what Samsung has provided...
There is also plumbBob GPS fix, but when I tried his version 2nd Beta 6, my GPS only saw 2 sats with no locks even with 10+ minutes of waiting... I did not try version 1 of his fix.
As for the GPS settings, use either Standalone or MS Based(some drift with this setting, much less than ms assisted) . Set your support server to google, distance to 80 and good luck...

MS Assisted = uses cell towers only to determine position. Intended to be used for 'dumb phones' that are not GPS equipped or where only 'coarse' location data is required.
MS Based = uses cell towers to provide approximate location for initial fix, then GPS thereafter.
Thing of it is, Samsung's configuration interface for the GPS is so silly that changes in LbsTestMode don't always really affect anything. If you're getting good results after applying this 'fix' it's just coincidental, or perhaps that you'd finally used GPS long enough to get almanac and ephemerides downloaded over the satellite signal and your GPS was able to function unassisted.
What about this has anything to do with development?

I decided to make this a separate post...
My original phone had all sorts of trouble - GPS was the worst. I don't know what my original one was, I do recall I'd applied the OTA update that was supposed to fix the GPS issue - it didn't.
So I got a warranty replacement phone - it worked fine out of the box, but the next day it was doing the same old crap.
This one came with the OTA update pre-installed. It's a "1010 rev. 0.4" if I'm reading the sticker under the battery correctly...
I read countless pages of stuff online, tried various "fixes" that were posted, all with similar results.
One discussion I read was posted by a guy who claimed some GPS expertise, and indicated that the problem was in the driver - to paraphrase from memory it was something like the cache was getting corrupted and the HW/driver wasn't cleaning it up.
He basically said that they needed to write a new driver, but until hen you could use a 3rd-party app to clear the cache and re-download clean data from the satellites.
I found a (FREE!) app called "GPS Status & Toolbox" by author "EclipSim" (Disclosure: I have NO CONNECTION to this guy, just like his app!)
It has 2 menu options:
"Tools -->Manage A-GPS State-->Reset" and
"Tools -->Manage A-GPS State-->Download"
After doing those, it will usually grab a fix within 15 seconds at most. Once it's "timestamp" is updating every second (you'll see, in the app) I can then switch to Google Maps and it too will get a fix before too long.
Another nice thing about the GPS Status app is that it shows you how many satellites you "see" vs how many you're connected to. When it only sees one or 2, or when it sees a bunch but isn't connecting, you can be sure you need to reset/download again...
This thing DOES eat battery - so it's a good idea to be plugged in, or to kill the app once you've got Maps working the way you need it to...
Yes - it's a PITA to have to do all this to get a basic function of this high-dollar phone to frigging work - but it beats having it NOT work...
Hope this helps someone!

Tested again last night on two rides. Worked great even sitting in the cupholder. Major improvement over my original Captivate which was returned for speaker problems.
not really much better for me.

Plumbob didnt do much for me. I am pretty well convinced that with the utmost optimization, the crappy hardware in the captivate can operate marginally well at best.
Ryans Plumbob fix does work. Its a much better improvement over stock on defected models. I had a 1009 and it worked great but the tracking and navigation were still buggy unless the phone was placed on the dashboard. (Always had a larger blue circle and would skip at times).
Finally gave up and noticed that the local atnt is a device service center. Went in and got a refurbed 1008 with stock 2.2 and the navigation is excellent. Even sitting in my lap...
I mean you all should still have the 1 year warranty. Just find a service center and exchange your phone. Hell the refurbed one I got was in better cosmic condition then my original.

i know everyone will tell me im wrong but try running the samsung gps restore app once then remove it from your phone. it is free in the market. and i assure you t doesn't revert to stock settings. atleast not in any location that i am aware of. i have checked the jupiter .xml and secgps.conf and lbs test mode before and after running the app and it doesn't revert anything. but it does seem to clear errors that may be caused by messing with settings without haveing a proper jupiter.xml or config file first. for instance on old roms if i chose msbased mode in lbs test mode it would work for 6 minutes and turn off. even after reverting the settings and clearing gps data the gps would turn off after 6 minutes. running gps restore or doing a factory reset were the only two things that would make my gps work again.
also yes google maps and captivates dont agree with each other 100% of the time. it is thought by some that the gps is recieving interference from the cell antenna (that's one theory at least) so the more data you use as you navigate the more issues you might see if that is true. try a gps app that downloads the maps to the phone. it takes up alot of space but if the app agrees with the phone it is worth it. in the past i had trouble with some aftermarket apps as well while others swore the same apps had solved there navigation problems, so try a few and find one that works. navdroyd is great on my phone.
also, though people are raving about plumb bob's fix, i have more blue circles with it. the problem is the msbased mode. it doesn't work on my phone very well. (back to the data/interference theory) i instead use Da_g's fix the control plane version with lbs test mode supl settings set to control plane and i turn off dynamic accuracy. and i use the kc1 modem. there are other modems with good gps but kc1 has the best call quality of them.
My GPS stopped doing accurate readings when i flash roms with the ziggy gps fix. the only way that it gets accurate(within 20m) is with wifi on and connected, if its off it says accurate within 3700m. Thats not too accurate if i might say, anyone else having this problem/ found a fix for it?

Interesting, I attempted the same thing and I am unable to get a lock when I disable the Google Location Services.
I'm running on Das BAMF 1.3.2 with the kernel update 3a which includes gps fix/enhancement from Ziggy.
I've been testing how quick I get locks when using the Navigation and I am still seeing a considerable amount of time before it finds a GPS signal. I've also used GPS Status from the Market to reset and download GPS data but I haven't really seen a difference.

Used this method and Ziggy's GPS mod and I get a lock within seconds as opposed to 10 minutes. If I turn on Google Services it goes back to a 10 minute lock time so I think it has more to do w/ the Google Services rather than modifying the GPS Config through Root Explorer.
Edit: I will add that initially my phone will say "GPS Location is Currently Unavailable" and 2 seconds later it gets the GPS lock /shrug
Well mine stays searching when the Google location is off, never gets a signal. What is the stock gps server so I can switch it back?

Well I just found that as long as WiFi is toggled on, the gps will lock on no matter if there's a connection or not. Tied into he WiFi somehow?

That is odd that WiFi affects the GPS locking. I'm trying to find anything I can on this. "Searching for GPS..." in Navigation is annoying as heck.
I also had a sneaking suspicion that toggling wifi on and off caused gps lock issues, I was using another rom at the time, but for some reason, all of those problems ceased when I flashed TeslaCoil and completed the gps conf fix.
Not withstanding, gps should lock quickly using only stand alone, and right now, my gps works splendidly

You can grab it here:
Improve GPS lock - credit Ziggy471
It edits the gps.conf so the NTP_SERVER=us.pool.ntp.org
That comes default on the roms I use tho. Still attached to WiFi switch. What's the closest lock you can get with your gps?

i was having GPS issues with the last two bamf kernels. google maps seemed to lock onto my location after a few seconds or a minute, but other apps that tried to use the GPS would never lock on. i noticed when you go into google mapls, the GPS icon/animation appears on the status bar.
the GPS icon would never appear for other apps that tried to use GPS when using the bamf kernels.
with the stock TB kernel, all is well.
Ok, gps is definitely tied in to WiFi. Without WiFi on its 3400m away and with it on is within 20-50m. That only happened with the ziggy fix so maybe if anyone could show me the original settings for the stock gps server file I could change back and forth and test what the problem is.

So I rewrote the gps.conf back to the original north-america setting and that fixed the problem. Any clue why ziggys rewrite of a word in that setting would mess it up so much? And how is it ppl are supposedly getting improvements with that, like what exactly?
Sent from my ADR6400L using XDA App
I don't know what the rhyme or reason would be for this gps issue, because it's so random, there is no pattern to this mess:
1. Got the phone, gps worked great.
2. Rooted phone, still worked great.
3. Flashed first rom, Virus to be exact, still worked great.
4. Several days later, with no rhyme or reason, I noticed that Cardio Trainer had not picked up location
5. Factory reset, problem still persisted, could not lock on to any birds, confirmed with gps test app.
6. Flashed CWR of stock rom post root, still not working.
7. Flashed RUU stock from fastboot, working again perfectly.
8. Have flashed 2 non stock roms since, BAMF 1.3.1 and first TeslaCoil (current) and gps still working perfectly
I can't think of what could have possibly caused this, but now that gps has been stable for about one week and I haven't been using wifi, over the weekend I'm going to toggle between wifi and 3g and see if it causes any issues.

Joanni, I'm having the exact same issue that you've been having. With Google services on, I get the wide area. If I turn it off, I get nothing. The only way I get a lock is with WiFi on. I'm currently running Virus ROM.
I know enough to be dangerous when it comes to digging into my phone. I generally just follow well polished instructions. How would one go about trying your fix?

Joanni just edited the gps.conf file to read NTP_SERVER=north-america.pool.ntp.org
That was the original setting. It has been said that changing the setting to us.pool.ntp.org has fixed peoples GPS locking issues but in my testing I found no benefit either way. What I have found, is that turning WiFi on will enable the GPS to have better accuracy in finding your location (20 meters to 50 meters in my case). This is exactly what the popup says, the first time you launch Google Maps.
If you wanted to check what your gps.conf file has set as the server, you can use Root Explorer and browse to /etc/gps.conf
There is also an app in the Market called FasterFix that will change the server to north-america.pool.ntp.org for you.
Hey all,
I'm using a rooted TB running BAMF 1.3.2, and my GPS location is anywhere from 5 blocks off to like half a mile off, usually. This is the case whether I'm using Google Location Services, Verizon GPS Services, or Standalone GPS.
Any ideas on how to fix this?
Try the new radio and latest Rom version. Or use the app gps status to reset your gps.

GPS way offArrow
My GPS jumps around based on what ROM I have installed. Right now I am using the Twisted Sense 1.51 and it's perfect.
The app called gps status, go outside and run it for a bit. Look at how many satilites you hook up to. Clear the caches in google maps and it should lock in your position.

GPS doesn't work...
Yeah.... so... GPS was working fine the other day. Location would jump around on the weather widget, but would work just fine using Google Maps or Glympse.... Now I get nothing. No satellites, and it's like it's not even looking. GPS Status, GPS Essentials and a couple others, and nothing at all. If i turn off verizon location and google location, all the apps act like i don't have any location service at all...
Still using stock rom, all I did was root, and GPS was working fine until yesterday.
Any ideas?
Edit: noob mistake. Shelled out the 4 bucks for root explorer, modified gps.config (mounted as ro with the free aps), rebooted and works just fine. Also bought the xda app cuz you guys have helped me with my tmo dash, vz touch pro, and vz imagio. Happy flashing everyone!
Hey again,
So, still no luck with the GPS. Upgraded to BAFM 1.6.3. Upgraded radio to 1.13.605.7 (1.16.00.0402w_1 CMDA) -- first one in The Obligatory Thunderbolt Radio Thread.
Still: my position is like 10 blocks off, and if I don't have Google Location Service turned on, it doesn't find my position at all, just as always.
Is there ANY help for my poor GPS?
mine was acting crazy also but with a diff rom. i got the new CDMA and old LTE and that fixed my problem. it would say i was 10miles away from my house or were ever i was

Nope.... the problem is it can't find any satellites....
And i want offline gps works. not online AGPS.
tried this one twice but still my gps can't find any satellites
I am in the same situation. My GPS used to work and then it stopped. I can't even remember what I flashed or whether it stopped straight after rooting.
I've tried a whole lot of different ROMs (JB/ICS/GB, AOSP/Sense) so its not a ROM issue. I've used the AGPS patch and all those other GPS apps that are supposed to diagnose and fix the GPS, non have worked. I have eventually put it down to a hardware fault and conceded that my GPS will not work.
I'm not wondering about flashing another radio. Will that make any difference ?
No, radio has nothing to do with GPS. If it's faulty - it might just be a disconnected antenna.
Enable data
I know its not the perfect solution but by enabling mobile data and the GPS you do get a precise fix on your location and it barely drains your allowance.
Mobile data doesn't affect GPS. All it does - it enables downloading almanac and ephemeris (satellite path charts, that tell the GPS where to look and for which satellites) instantly from the dedicated internet servers, and it also allows more precise clock synchronization - all that to make the lock faster. It doesn't help maintaining the lock.
And even without mobile data, at least 1-2 satellites should be visible almost immediately.
