I'm on Froyo leak no root or Cognition. Same results as you. The GPS is usable if I keep in on the dashboard. As long as I hold it in my hand or in the car roof then the connection becomes unstable. I guess we will have to live with it. I have no issues with locking or sustaining lock.
[Captivate Android Development] TheSopranos16:
Is it the car roof above it or the fact that you hold it in your hand that messes it up? Sounds like we have GPS Antennagate lol
[Captivate Android Development] Darryl Henley:
I'm having the same problem on Cog 5.5
[Captivate Android Development] pkley:
I'm not having that problem, mine worked on two hour long trips, but like others I had to hold it next to the window for it to track correctly, I couldn't put it on the dash due to how windy the road was.
[Captivate Android Development] krupawan5618:
I know people already know that this forum is the step in the right direction, but I just wanted to reaffirm this notion...

I thought that my GPS was for sure busted until I implemented these Jupiter files. I now know that my GPS is capable of getting a fix, although not entirely accurate. I will test it in the morning on the way to class...
[Captivate Android Development] ewingr:
Either one.

More specifically when holding...if I lean forward and hold it up in the window so no roof overhead, it may work for the most part, but occasionally get the blue circle. But if I mount it in the ugly window suction cup hangey tird thing, it works pretty much great all the time.

That being said, I have yet to navigate through some of the city areas I know my past unit to have problems hooking to wrong streets, and likely won't be able to be past those sites for a while.

I guess I can live with it like this, as I don't use the GPS all that often, but want it to work spot on when I do.

More time will tell.
[Captivate Android Development] Dani897:
ok i did one more test, my gps turns off after 5-10 minutes when i set lbs test mode to ms based. in stand alone it seems to work, at least for 20 minutes( i didnt have hours to go driving around to test it fully ), im not sure its not a coincidence but it seems to be the case. i was begining to believe that lbs test mode settings only worked in lbs test mode but it does seem to influence the way it acts in google maps. even if it doesn't work like it should.

what are the chances that we can find the cause of the gps turning off when set to ms based? is this a problem others are having?
[Captivate Android Development] thejonesyboy:
GPS never locks

I know this problem has probably come up earlier, but my GPS doesn't work AT ALL, and hasn't ever worked since JF6.

I've since tried previous SRE updates and all successive versions of Cognition. (I've been following the forums for a while now). I tried stock JI6. I'm currently at JI6 with Cog 2.2b4 and Jupiter v6, but still, no lock even after waiting several minutes in google maps.

I never get any lock at all with only 'Use GPS satellites' selected. Using 'Use wireless networks' does give me 500m - 1500m accuracy but this never reduces as it seems the GPS is doing nothing.

Someone please please help me :-(

I love my beautiful phone but something is wrong with her. I hope it is me doing something wrong :-)
[Captivate Android Development] xetrev:
I pretty much noticed the same thing on an hour trip i took a couple of weeks ago. If i held it near the drivers side window it worked pretty good but if i put it on the dash by the windshield it was SPOT on.
[Captivate Android Development] Dani897:
i have the body glove case and it gives me a bit of grip so what i do is wedge the phone between the dash and the wind shield. works great, what i really want though is a way to mirror the image and use it as a hud, i get a nice readable reflection off the windshield.
[Captivate Android Development] creepyncrawly:
Here are some things to try before you give up on your phone's GPS:

Turn off Use Wireless Networks.

1) Use "LBSTestMode | Get Position Test" under an open sky and let it run for 20 to 30 minutes before you decide your phone is not capable of getting a lock.

If you are not familiar with LBSTestMode, it is already on your phone, you just need to know how to open it. There is an app on the market called LBSTestModeLaunch, or use AnyCut or Launcher Pro to set a shortcut the the LBSTestMode activity. There is also supposedly a phone dialer code that works with froyo to open the application.

2) Tweak the settings in LBSTestMode and try 1) again. You can find many threads with information on which settings to tweak. Probably the main one is to set the server to supl.google.com, port 7276, although people report differing results.

3) Download and install the "GPS Status" application from the market, then go to "settings | GPS & Sensors | Manage A-GPS state" and click on the "download" button in the resulting dialog. This will download an almanac that will help the GPS find the satellites. Presumably you would need to make sure AGPS is turned on in settings in LBSTestMode.

The author of this program is very knowledable about GPS, and there is a lot of good information in the help files.

4) If you are able to get a lock in LBSTestMode by using Get Position Test, leave the test running by using the home button instead of the back button to return to the home screen, then open your map or nav or tracks program. Having the test program running in the background seems to help the map program keep the lock.

Hope it helps.
[Captivate Android Development] schtuka:
I tell ya. Today was the first time my phone had a consistant lock for entire drive to work (Lake Shore Drive about 8 miles) including my speed burst to 60 mph and sitting in the traffic. Never had that before. It only started to be off by 10-15 meters once I hit the streets between highrise buildings.

Funny part is that I actually deleted previously installed V.006 jupiter and gps.conf because of no positive results. Left secgps file alone.

Same settings:

supl.google

secure socket off

ms based

I do not know what happened to my GPS or what will happen in next few days, but the only things I did recently to my phone; I updated my kernel with 2e-recovery to get clockwork rom manager working and I disabled time sync and using ClockSync apk to sync with atomic time.

Oh, I also removed Ryan's OCLF.
[Captivate Android Development] foxbat121:
The mode setting only affects lbstestmode app. But once your successfully obtained lock and downloaded enough data to the phone, it will affect all the subsequent GPS lockability as long as you're not too far away from where you last get locked or too long in time (it expires in a few days).

Android OS support all the GPS modes (and the phone maker set the corresponding capbility bits to OS). It is the responsibility of the app to reuest which GPS mode it needs to use.
[Captivate Android Development] ScottyNuttz:
Has anyone expirimented with the GPS Optimisation software available on the market?You are supposed to run this program WHILE running a program that is accessing your GPS, and it will some how boost it.

http://www.appbrain.com/app/gps-optimisation/com.gps.opt

Anecdotally, I have not had a sat lock in a week, and when I tried this, I got one finally (not a strong lock... but a lock nonetheless).

I am curious about what exactly this program does, so if anyone has some info they'd like to share, that'd be good.
[Captivate Android Development] Xaltotun:
Can't find LBSTestModeLaunch anymore?

Anyone can kindly send me the URL for the package itself (as a direct apk download)? Or attach it here as a file?

I did not find it on the Market (is it because I am in Canada???) and I get the same result when I ask for a download URL from the developer's web site. I get the e-mail, click on the URL, and I get the "not found in market" message....
[Captivate Android Development] Cobra302:
thanks for this, i just downloaded it, updated and left it running, google maps indoors was almost an instant lock. the navigator even started to work properly instead of saying searching for gps! i hate that this is required each time to get it to work though. sigh.:(

[Captivate Android Development] Dani897:
this is what I thought but if application setting in lbs are set to ms based my gps fails after 5-10 min, not loses a lock or become in accurate, the gps turns off, the icon disappears from the notification area, and it will not regain a lock till I restart maps. this only happens in google maps, my tracks works fine. I'd say it was coincidence if the symptom wasn't repeatable.

edit: consistently dies after 6 minutes in clear view of the sky, but if lbs test mode application settings is set to stand alone, it works without a hiccup.
[Captivate Android Development] Sulphur4724:
I don't think you have to do it each and every time you use the GPS. The info it downloads stays with you a couple of days, at least if you are in the general neighborhood of where you first did it. This is my experience anyway.

Mine is working pretty good atm. (But it definately HAS it's moments!) shep's jpk rom, loaded, none of the assist stuff turned on. (Maps complained about this. A LOT.) A 15 and a 25 mile trip, each way and it was spot on for both trips, both ways. No tracks. Sorry.

Oh, I have a dash mount btw.
[Captivate Android Development] MrByte:
I think I am going to give up on this phone. It seems as if some things can be solved with some software/configuration "tweaks", but there's definitively a hardware component. I am still within my 30 days, so I'll just go and exchange it and hope for one that works..... I've tried different ROMs/settings and they are all a hit and miss.....
[Captivate Android Development] ewingr:
I'm about to decide that it'll never be as functional as other phones' GPS implementations. Last hope is Froyo implementation on it, but I'm pessimistic about it.

I posted earlier about good results over 500 mile trip, but this morning, I had it showing be driving through a building.

I guess I'll live with it, as it is good a very high percentage of the time. My analysis of other phones left me underwhelmed compared to the SGS unit.

What method are you using? Using root explorer you should be able to move it from your sd card to the correct place...assuming you are rooted of course.

[Captivate Android Development] hayslett4:
Okay, I've been holding off to see how well Jupiter V6 was working before posting. I was using the custom settings posted numerous times throughout numerous posts and only seeing 5-6 satellites with only 2-4 intermittent locks. I linked to LbsTestMode and used the following settings:

Application Settings:

Session Type: Tracking

Test Mode: S/W Test

Operation Mode: MS Assisted

Start Mode: Hot Start

GPS Plus: On

Dynamic Accuracy: On

Accuracy: 50

GPS Logging: Off

SUPL/CP Settings:

Server FQDN Type: AUTO Config

Server: h-slp.mnc410.mcc310.pub.3gppnetwork.org

Server Port: 7275

SUPL Secure Socket: Off

AGPS Mode: SUPL

I found and locked onto 8 then 10 satellites in about 20 seconds using GPS Essentials App, then I tried Nav and my position was found in about 5-6 seconds (after using GPS Essentials). This was at 2:45pm in Lynchburg, VA... relatively clear sky with a few clouds. Captivate was in my lap while sitting in the truck.

Just wanted to throw this out there and possibly try to help with this GPS stuff. I've heard that the settings in LBSTestMode are all just local and not global, but this is what has worked for me so far.

Take care!
[Captivate Android Development] newter55:
It is at the root of your internal memory...root explorer opens at this directory....just / then scroll down to system. You might need to click the mount r/w at the top to be able to change anything though

I had my phone rooted, with busy box installed from the market and root explorer and could see the ect directory but couldn't open it. I'm not entirely sure why.

There is another app called android mate that should work if you don't want to buy root explorer
[Captivate Android Development] Gr8Danes:
I have been doing some digging around, and I see that the GPS chipset is sandwiched behind the screen between the screen and the board. When I take the cover off the back of my phone and flip it over, I notice that my signal improves compared to face up. Also, like many, when you put it on the dash compared to just in your car (such as on your lap, or on the center console), the signal is improved. I am getting more and more worried that it is the location of the chip than a software problem. Does this chip use any kind of external antenna? or is it just the chip alone?

Also what other phones use this exact chip? and where do they locate theirs within the phone?

I really hope that I am wrong and that there is a fix. :(
[Captivate Android Development] newter55:
Did you mount as r/w? You should be able to get into everything with root explorer...including some stuff that will bork your phone

Posted from my phone using some technology I don't understand
[Captivate Android Development] Dani897:
Yes I did, I'm running a different rom now and not having the problem anymore, I was just making the point that some can't access /ect directory in root explorer. I still don't know what the problem was though.

And yes I know I borked it a few times, at least once with root explorer.

[Captivate Android Development] Dani897:
I had a similar issue, what are your lbs test mode settings?
[Captivate Android Development] slyguy2000:
Tried both hw test and sw test, with no change in performance. Works best as standalone, GPS plus on, cold start, everything else off. Using supl.google.com 7276, no secure socket, and control plane.

Delete GPS info, and I get lock in less than 20 seconds cold, and under 10 after that. Indoors I can hit 8 - 9 sats indoors with 20 - 36 in signal, and can maintain a moving 3d lock until it goes to sleep.

[Rom: leaked ji6 froyo, rooted, e2 recovery kernel patch, Jupiter006, removed bloatware, enabled sideloading]
[Captivate Android Development] slyguy2000:
The weird thing is, (using CoPilot) I can watch the GPS bars in copilot and have a continuous 3d lock while moving, and the sat signal bars are all rocking in signal strength and its like the GPS goes to sleep. The bars will freeze with like 10-12 says all locked in, and then at the top dock bar, it loses the GPS icon, and copilot says No GPS Signal with all the bars frozen in time from the last received sats. Does the same thing in GPS Status app, Navigation, Google Maps, Rmaps, etc... its like the GPS is going to sleep for powersaving or something.

you mean a re-flash of the same rom or changing to a new rom? I like the rom I am at, and have it almost perfect, just can't issue "Fix Permissions" in ClockWorkMod Rom Manager, and my GPS is flawless now except it currently has narcolepsy. othern than that, I am totally loving my Captivate now.

Cog 2.2B6 + Jupiter 6 Results

Well, I foudn improvment, but still quite poor compared to Cog 2.16 or 2.17, even w/o Jupiter updates.

I'm moving back to 2.16 for now.

And, I am pretty discouraged about the GPS ever working like it should on this phone.
[Captivate Android Development] slyguy2000:
I did a full re-flash and it didn't help... what I did notice, was when I finished flashing my system was again back at Read Only, when I changed it back to Read/Write, I notice that my LBS settings changed... bizzare, so I reset them back to what I have been using, and now, after 2-3 mins, it goes to sleep for a few seconds, and then wakes back up... could that be the problem all along? When it wakes back up, it takes a few seconds to get a lock, and when it does, it's a wide lock, and doesn't get tight fix for a few seconds, and that is when I am driving through buildings, and on side streets...

at this point, I think it's driver related, or hardware issue...
[Captivate Android Development] MrByte:
Went today to AT&T. Was my last day of the 30. Swapped out phone. WHAT A DIFFERENCE!! Locks within a few seconds and now driving it actually shows where you are...... I will probably to the Cognition update... let's see how it behaves after that.

[Captivate Android Development] shinji257:
There have been various theories that I have seen. Someone mentioned that deleting gps data results in locks that hold even when moving. I was over at android central and their recommended setting involves using ms-assisted rather than ms-based or standalone. I did use ms-assisted and it seemed to grab a lock much faster. Now then it may have to do with the fact that I'm walking distance from a cell tower (a older cingular one) but I can't tell. I'll have to test it tomorrow to see. I did an indoor window test (too late to go outside right now) and with ms-based it maybe got 1 sat. On ms-assisted it listed like 9 right away. 2/3 of them disappears then came back. I got a lock in 5 minutes with 10m accuracy on lbstestmode. A lock occured on Google Maps within a few minutes and the gps icon had disappeared when I exited lbstestmode.
[Captivate Android Development] rogerhe:
I study survey in university, and i know the cell tower time has no relationship with location, the the GPS receiver will calculate the time as a parameter. And if you use AGPS, your almanac data is not come from cell tower but from the ntp site.
[Captivate Android Development] boomerod:
See my signature for what I'm running...my GPS locks very quickly on this setup, but tracking is still poor. I have not made any changes to the AGPS, or tried any of the jupiter files from this post.
[Captivate Android Development] crazililazn:
hmm, so i ran all the settings in the thread that xaltotun linked to:

http://xdaforums.com/showthread.php?p=8556517#post8556517

And I get locks within 10 seconds now. Have not tested any tracking so i will report on that soon.

Running Cognition B6

Update: When using MS based, tracking is terrible, the gps often misses the fact that i have turned and thinks i am continuing forward.

Using standalone is a bit better, but still has times where it misses the fact that i have turned.
[Captivate Android Development] askpcguy:
I can say for some reason when I tried the i9000 rom, I saw my GPS performance improve. Before lbstestmode would take a minute or more to lock and on i9000 it took seconds.

I'm sort of thinking about going back to i9000 but I dread the backup/restoring process!
[Captivate Android Development] derekedw:
Thinking of asking for a new phone. Is some of this caused by faulty hardware where newer phones have been corrected?
[Captivate Android Development] newter55:
I don't know if new is better. We got three captivates at the beginning of august and all were ok with gps but one developed an issue with the screen where everything was washed out..no clarity for some reason. As we were outside of the thirty days, had to do the refurb thing. The one I got back shows 6/28 in the rf cal date and the gps is petty much flawless...no swapping jupiter files needed, it just works. And although I change roms a lot, and I agree that the i9000's do improve it slightly, it never fails to work.

It's your Vulcan mind meld powers, I'm telling you, that's what it is. On a serious note, it really seems to be hit and miss for every one. Some work fine out of the box, some don't. The fixes work wonders for some people while for others nothing works. Mine was pretty bad and nothing really worked until I used Cognition's Froyo 2.2 b7. Now it's 95% fixed, it loses me at some intersections but finds me quick. I always run an lbstest before I fire up Nav and that seems to do the trick.
