I've been (mostly) lurking on XDA boards for a couple of years, having had a Droid X, Droid Charge, and lately an Inspire. I am a confirmed flashaholic, and historically rarely stick with one ROM for longer than a few weeks.
The Inspire though, presents an interesting and somewhat frustrating problem. In a nutshell, I am unable to hold a GPS lock for longer than 3 minutes at a time on anything other than a Sense ROM. In digging around on the boards, it is clear that this is a known issue on the Inspire (Desire HD too) running anything built off of CM7. Now, for the average user this might not be a huge deal, but I drive a tow truck for a living and rely heavily on GPS for trips, every night.
I have attempted each and every fix available for this problem, with no lasting success. It's a shame because on occasion I love to run pure CM7, and the Inspire has a superb CM7 hybrid available in Absolution. And now the AOSP ICS builds are nearing completion, but they still present a problem due to the CM7 parts used. Why am I stuck with Sense on this device in order to use Navigation effectively?
To be clear, I love this phone, not going anywhere, and I've got Sense 3.5 growing on me just fine, currently running Mikrunny, but I do miss the stripped down speed of CM. Why was this never addressed by Cyanogenmod's team? It's documented, even on CM's own boards. Can't blame the devs here, they are working off of source that is inherently bugged, or deficient, IMHO. Have tried countless market app fixes, GPS Test, GPS Status, etc. Found a great thread on the Desire board that greatly improves the number of satellites visible to the device and the speed of the fixes, but none help hold a lock longer than 3 or 4 minutes at a time. Frustrating.
Purpose for this thread? Well, to vent a little I guess, but more importantly to see if anyone with deeper knowledge than me on the topic has further insight...a HEAVY GPS user like myself perhaps?

the problem lies in google maps. least from what ive read and experienced. if you use different navigation or gps software theres no problem at all.
give Waze a try
OK. Will give Waze and/or Sygic a shot. Thanks for the reply.

If you toggle your gps off then back on after you've opened and gotten a lock in navigation and it will
Stay locked.

I'm having very good fixing and holding on black ice ROM with crypted's agps fix ( http://forum.xda-developers.com/showthread.php?t=1252011), specifically the "at&t flavored" option.
I am also using CM7 and I found that modifying my gps.conf as described in this thread really helped me. I was having troube getting a lock at all, would try for 10 minutes, but now I can get a lock in under 1 min.

I use GPS Status to get the A-GPS data.
https://market.android.com/details?...wsMSwxLDEsImNvbS5lY2xpcHNpbS5ncHNzdGF0dXMyIl0.
I've also found that turning the gps off and back on at the initial signal loss works well. I field tested my inspire using an ics rom on a 2.5 hr road trip. It did lose the signal within the first 2 minutes, but toggling the location services button fixed it. After the first drop I kept the signal for the entire trip, both ways
I may have found something, but I need a few others to try it out and see if it is reproducible.
If folks here are comfortable modifying their build.prop file can anyone give this a shot and post back here if it worked for them?
Change
ro.product.model=Desire HD
to
ro.product.model=Inspire 4G
Reboot.
Test the GPS without toggling.
A couple of caveats. I'm running on the BlackIce ROM (a CM7 derivative which does have the gps toggle issue still) and I have applied crypted's AGPS patch (which improved the lock considerably but did not fix the toggle bug).

Doesn't make a difference. Download GPS Status from the market. Before you fire up Google maps run GPS status first. As soon as it downloads the assisted gps data fire up Google maps and you will be good to go.
GPS Status is useful but it doesn't address the toggle annoyance.
Did you actually try the build.prop edit?
I also use blackice with crypted's 3.1 gps patch. Google navigation is buggy, but I like to drive my very light car out in the stocks on the twisties where their is edge, gprs, or nothing. So, I use Navigon. It's gotten better now that garmin bought them and the routing engine is leaps and bounds better than Google. It works flawlessly.

Are you serious? Its a $40 freakin app! https://market.android.com/details?id=com.navigon.navigator_checkout_us&hl=en
I'm dead serious. It's worth every penny if you need gps and don't want to be subject to the propagation of radio frequency for your map data. It works very well. Some people ***** about it not working, but my guess is that they are incompetent. Also, navteq has the best map data for North America. I can uncheck a box and it'll route me on rural roads that would require a custom rock crawler to traverse.
Also, I tend to get the best gps and everything else results with radio 12.65.60.29U_26.14.04.28_M.

But the question is, will it come on by itself without having to toggle it off and on? Mine gets a fast fix and will stay connected so long as I toggle it off and on and don't let the screen time out or close the program. Any of that happens and I have to toggle it again. This is with CM7 nightly 260.
I am using a stock Inpire 4g (for now). FWIW, If Google maps/navigation is the first app to attempt to access the GPS after the GPS has been turned on, it will never get a signal lock for me. I have to run GPS Status (a great app) before trying anything else. Sometimes this means toggling GPS off and back on, running GPS Status, waiting for lock, and then resuming Google maps/navigation. Even if I start Google, realize my mistake, and then run GPS Status with Google still in the background, GPS Status will "see" as many as 10 satellites with strong signals, and never get lock. I only have to run GPS Status once after GPS has been turned on. Then, if I leave the GPS on, I can use any other app as much as I want with no problems.

After flashing to Cognition 2.3, I've never got a loc again, and now cog2.4, still no loc. and between them I've tried Doc's i9000 roms, none of them can find even one satellite in the sky.
My GPS used to work, although always took 30 seconds to get a fix, it worked most of the time, and now it's totally in hell.
So I'm asking, is it because leaked roms don't have optimized GPS settings or is it just my GPS chip broke sometime? I'm really thinking about replacement...
I think it has to do with cognition as dg doesn't implement any gps fixes. This happened to me too when I was running cog but as soon as I switched roms (with some lbs tweaks) my gps was fine again. Run another rom and apply some fixes and you should be good to go.

Go through and experiment with LBSTESTMOD configurations. That is all I had to do with Cognition 2.4, and it worked.
I have had the same problem with that cog build. The only real time I use the gps is when I go for a run. I have never had a problem getting a lock on my run but with this version i have almost no chance of getting a lock at any time. So my opinion is the gps problem Is only related to this version.

The one I am on (Android Revolution 5.1.8) and GingerBeast (2.1.2) I had before this, I generally got lock in seconds, and with an accuracy of 5-10m.
I would say the GPS on sense based roms with the correct gps.conf file works just as good as the stock rom.
Right now I'm using Android Revolution 5.1.9 and I get almost instant lock (about 5 secs) and 5~7m error.
Radio and RIL also play a very large part in it as well, I have had great luck leaving the gps.conf file as is and just flashing the updated stock radio/RIL combo. Locks in seconds unless obstructed.
This also includes CM7 Nightlies after 57ish.

Works fine for me on cm 7. I don't turn it off and on. With gingerbread its really not necessary in aosp type roms it only activates when needed the power drain is minimal.
funny, i just flashed back to the stock rooted rom with sideloading (http://forum.xda-developers.com/showthread.php?t=1058042) because I've realized I had ZERO dropped calls or connection issues on the stock rom. i was using ar4g 3.7 anyways because I found it to be the most stable and quite quick. wish it had a custom kernel.
back to the point, I had issues getting GPS working on that too, even with matching ril and radio. hopefully I won't have any more issues with this rom
For myself, it was much better when I was on stock rom, but since I love testing out new roms, I've learned to live with it... At least it'll still work most of the time.

Dang I was just playing with this guz I'm kinda a GPS freak, and this Inspire, if one thing sucks, it's the GPS. Forver to get locks, and closest accuracy radius ever achieved is 7 meters....any suggestions? GPSFix, GPS Essentials doesn't seem to help. Ugh...guz me likes me my accurate GPS on my phone thingy....I was hoping that when I root it would improve but this feature probably doesn't get a whole lot of attention form the devs (?)
Edit: It is marginally better than the aged iPhone 3G I had, but I took it apart when it almost dead (I kilt it off by some wild ass idea I was going to refurb it) and there were signs of oxidation around the GPS antenna, which makes sense because my perception was that the performance degraded over time.
After upgrading to cm7.1 rc1 my inspire can't get a gps lock. I'm starting to get a little bored of cm7 anyways so I'm looking for other roms to try, preferably AOSP.
The only feature that I must have is volume button music control.
any recommendations?

With mine it took it a few minutes to get a good lock after I rebooted. Download the GPS Status app and it will show you how many satelites you are locked to. It might take a few minutes to connect but you should get 5-6 connections for a good position.
Where does it show how many satts your on
Sent from my HTC Inspire cm7 nightlies
It should show you a number right to the bottom right of the compass and it will tell you how many satelites it detects and how many you are connected to. It will look like 5/6 (five being how many are connected, 6 being how many are present). It might take a minute before that appears.

My current phone got stolen, so I need something on a budget for the meanwhile. I was thinking of getting a captivate since it has lot of development with stable ICS builds..
My only concern is the GPS ? I had heard there were problems initially with early galaxy S units, resulting in poor GPS performance. Do they still exist in ICS roms or were they fixed ? Also if anyone know were these on hardware side or if they were just software bugs?

There are several threads on the gps problem and it's not related to rom, per se. I am on GB and changing the etc/gps.conf file has made my GPS reliable. The position of the GPS antenna inside the phone is far from ideal and samsung didn't ship it with best settings in the gps.conf file.
if you search for 'gps.conf' you will find the threads. it is pretty simple to replace the gps.conf file or edit it.
Some ROMs include the gps.conf fix.

I love many things about my captivate, but the GPS is not one of them. There are fixes that help some, but it still seems too unreliable. If I'm driving it loses signal all too often.

For a decent gps signal I flash H3llstorm GPS Fix after flashing a Rom... Still Doesn't compare to other devices signal strength, but makes gps usable
It works on CM9, AOKP and MIUI
-Sorry for bad English
GPS, also, depend on your baseband version.some baseband firmwares consumes more battary charge, but gives better GPS signals. I use XXJVT modem and have no issues with GPS signal.
I figured out something cool. If I hold my captivate up to the windshield it will lock on nicely, whereas if it's in my lap when driving it won't. Then I have a windshield mount where I keep it. It's been working better. This has been true on AOCP and jelly bean.

After flashing to latest stable Cyanogenmod 9.1 my GPS is very good. I get 8 out of 9 satellite lock in about 5 seconds where it used to take 30-40 seconds with stock ROM and about 20-30 with 2.3.5 ROM I used for a while. That's in exactly the same spot right in front of my house.
that's the only thing i hate about Captivate @@
GPS is unbelievably weak, it has to combine with gps from mobile network, i can never use pure gps with only satellites @@
The GPS is my least favorite component of my Galaxy S.
I do use my Captivate as my GPS while geocaching.
I find that for best reception I have to hold the phone so the back is pointed up. To do this is is slightly over my head and I have to look up at it. Going though some trees and leaning over the phone it will loose connection. In the car driving I only find occasionally it will loose connection. In the mount on the dash it is in the ideal orientation.
My Transformer Prime tablet has an even worse GPS but the update external GPS add-on improves the GPS to be much better than the Captivate.
If it realy matters you can get a blue tooth GPS that can work with this and probably any phone you might upgrade to in the future.
I am running ICS on my phone and under Location Services there is GPS source to select different GPS. I just tried to connect using bluetooth to my Garmin car GPS but the only bluetooth functionality it has is to send sound to car stereo. and I could not even pair the Garmin with the Captivate.
Lots of bluetooth GPS receivers to choose from on eBay.
This thread might give you some more information of some of the units others have tried.

Honestly, you don't choose the Captivate for its GPS. Although, many ROMs have GPS fix and makes it usable. I can't say I had much issue with mine, it does the job it needs to do but depending on your connection, it might not be optimal. I did lose signal for a few seconds while driving but never lost signal to leaning over it tho eh
I almost want to say that the Captivate has the worst GPS out of most phones but I don't have much experience with other phones. The captivate is decent though and I think with the latest versions of JB, it seems to operate much better.

I've noticed that the google nav app maybe sensitive to the accuracy of the system time. When the clock is off by more that a few seconds, it seems to consistently report my position incorrectly, by 50 meters or more, in the same direction.
For example, when driving southbound, it will show me driving south, but 100 meters off the road to the east and this offset will persist until the clock is corrected.
I've installed clocksync app and set it to sync time every hour. It seems to help: Google nav doesn't give the persistant offset, but it does lose lock sometimes. I just toggle gps enable in the status bar and it recovers.
My gps.conf file uses the hellstorm fix. I am running GB debloated stock rom with Corn 7.06a kernel.

Good. Is there a "best" for GPS? Seems most JB have issues and several ICS as well from what I've read so far.
JB doesn't have GPS yet. That's its issue, but airfluip1 thinks he might have some ideas on how to fix it. Hopefully he'll get it working, or Erik will, or someone else maybe. But for now, skip JB if you need GPS.
ICS has 3 different options for GPS, and it's not always apparent which is better.
1) Assisted GPS. This requires having a build.prop file that tells your phone how to use GPS for this. Most of our ROMs want to do this, but end up in number 3 instead. There are directions on how to fix this if you aren't using Ultragen, or just use Ultragen which comes with this properly configured from the start. First connection to GPS may take 15-30 minutes, but it should be much faster after that.
2) Non-assisted GPS. This comes from flashing YAGF. It disables the assisted GPS and just uses the satellites fresh every time. This CAN be much faster, but won't work well in clouded/wooded/indoor areas.
3) Bad GPS. This is when 1 or 2 fail, generally number 1. The phone is told to use AGPS but it's disabled in the build.prop, or any of a wide variety of other issues. GPS will work... sometimes... but it's highly irregular.
Best option? Start with Ultragen (remember... 1.0.1, not 1.0, which had several major issues) and see if the AGPS is good for you. If you don't like it, flash YAGF and go to unassisted. Decide it's worse and hate it? Wipe the ROM (to get out the modified system files) and reflash Ultragen.
Or start modifying your own files, but be careful that your phone boots up. Don't use Microsoft Word or Notepad or Wordpad or any of those tools. Use a proper hex or *nix editor.

Just a suggestion, but the Pimp My Rom application https://play.google.com/store/apps/...sMSwxLDYsImNvbS5hbmRyb2d1aWRlLnBpbXBteXJvbSJd under GPS Tweaks will download the proper GPS files for location, or alternatively, you can install the GPS Status and Toolbox App https://play.google.com/store/apps/...wsMSwxLDEsImNvbS5lY2xpcHNpbS5ncHNzdGF0dXMyIl0 which you can set to download the newest AGPS File when you open it.
I am using AOKP ICS and have no issue with GPS. Was getting like 120 sec TTL for like 12 Satellites according to GPS Tools, which is not terribly life affecting for me.
Which... is irrelevant if your build.prop doesn't use those files. As I said. You can tell GPS Status to update every hour, but if the phone isn't set to use them, they're helping you as much as throwing the phone up 20 feet into the air (without twisting it). Slightly less, since they're using up storage and not getting your phone closer to the satellites.
That being said, the TopNTP app did have GPS modifications as one of its options. Not sure if it does the build.prop flag we need, but...
Wow, it seems the SGS4G may actually be worse than the Vibrant for GPS.

I've been testing a new kernel for Beastmode lately and was trying to get GPS to work. I flashed 3.1 google specific build and still no lockie. So I did what cryptic mentions in the OP and READ the notes. Well that note that I quoted up above is the thing that needs to be done for this phone to make GPS work. After I added that line to the build.prop and rebooted I got a lock in about 10 seconds indoors to an accuracy of 6 meters. Not bad for this phone at all.
Most of are ICS ROMs use CM as a base. So after going through and looking at most of their props NONE of them have that line. I don't know how it's escaped notice as long as it has. I've only tested it on CM9 8-29 build with Beastmodes yet to be released kernel. I doubt that it matters though. Flash the zip, add that line, reboot and you should be good to go.
So thanks to cryptic for this fix and one of the most detailed OP's I've ever had the pleasure of reading. And too erikmm(aka Beastmode) for the incentive to actually look into this.

Thanks ! Where can I download YAGF for a T959v ? Is Ultragen v1.8 also good or only 1.0.1 ?
Remember that you have to flash something that actually works on our phone, unless you're making your own franken-build.
Ultragen 1.01 is available in post 4 of the Ultragen thread. There is no Ultragen 1.8... at least, not here on XDA for our phone.
Regarding the GPS, it's the same YAGF2 from the Vibrant forums... it's just a generic-ish fix that may or may not placebo you.
Unfortunately, I don't understand the technical jargon regarding all the GPS options...maybe I'm better off not knowing.
However, I'm running CM9 with Proton kernel & LB6 modem and everything works (except, of course, for wi-fi calling).
No problems whatsoever with GPS. Battery drains a little fast but I have a zillion chargers laying around the house,
office, & car...no big deal.
