What do you mean ?

You obtained best performance with XWJPA ? applied this fix to XWJPA and got best performance ? Are you asking for this update.zip to be flashable on XWJPA ?
[Galaxy S I9000 Android Development] °Dexter°:
Oops,not so clear,i guess :D

I had the best gps performances ever using XWJPA "base rom"...so i was asking for a flashable package based on XWJPA gps files,to use them with other versions (axura,JPO,JP5,etc)

XWJPA gives best GPS performance

EDIT 27/11

XWJPA best GPS rom. Don't go with JM9 fix if you're on WXJPA. JM9 is quite good - but it's not better than XWJPA (in my tests)! I tested this as written above, by monitoring sat.lock + S/N with "GPS Test" sw from Chaincross.

So yesterday I installed DOC's XWJPA v8, hence my JM9 gps-fix was overwritten. So started testing again and to my big suprise I saw an even more stable sat.lock (not jumping around) and a better S/N ratio (33-45).

This is by having the settings "as is" with std. firmware! Well not quite, cause there is actually one small tweak that I do - and I don't know if this is related or not, but I strongly believe it works, and it results in 9-11 sat.lock with high S/N.

The tweak is:

> Go to SGS tools (download from Marked)

> Go to "Secret Codes"

> And find "GPS-Test and settings (LBSTestMode)"

> Click on "Application Settings"

> Scroll down to "Accuracy"

> Change this to 40 (50 is default). Tried different values from 20-100, but 40 gives the best result

> Go back one step and "Delete GPS Data"

> Reboot phone

> Go outside (or go to a window) and start GPS Test. Face phone vertical for best reception

> Wait for a solid lock, that is 8-10 sats

> Done and ready to go

IMPORTANT

Always be sure that you have a proper sat.lock before moving around! This has shown to be THE biggest cause to error and a very jumpy GPS performance. Also, as mentioned, the SGS gets the best GPS signal while facing vertical and not with any fingers on the back. So if you use in your car, get a holder!

With these setting I alwys get a lock within max 30 sec and typical to 5-10 sec. This together with constant lock on 8-12 sats (typical 9-11) while driving around.

My Wisepilot Navigation sw is truly rocking with these settings and it hasn't lost me even though I tested it through some very-tiny-close-to each-other-parallel-roads in between blocks.

:D:D:D:D:D:D:D:D:D:D:D:D:D:D

EDIT 3/12

Now running Doc's v9 of XWJPA and GPS is still rock solid (changed accuracy to 40, as mentioned above). Truly happy with the GPS now

[Galaxy S I9000 Android Development] Malorkus:
I flashed this on my Captivate on top of Cognition 2.3b6. Used GPS and sensor aiding but not Wireless networks. Google Navigation maintained a lock over my 1 hour commute for the first time ever.

Appreciation Post

Wonderful thing i must say!

I first did the tweaks told in some previous posts on this thread. It didn't work (tested only for 5 mins though), lost all hopes. Then I installed the GPS fix from CWM. Rebooted, checked the tweaks, they were still there. Now I use my GPS... and.... BOOM! Awesome accuracy, awesome sat locks!

God bless you people! I don't earn, the day I do, my first donation goes to Doc and then you!

Was just wondering, If you could release GPS fix for Doc's every ROM that comes out, with some advertisement around the forums, you'll receive loads of donations. (srry if this suggestion offended you in anyway)

Love you people, THanks a lot, you have no clue how much you've pleased me with your talented work!

Thanks again.

Update on GPS settings 4/12

Today I did a very thorough test using SGS as GPS navigator and the result was truly great! I must say - after fumbling around with the settings - my SGS is now performing as good as my g'd old garmin nüvi 660!

Since my former post, I've updated my rom to Doc's XWJPA v9 (great rom btw) and running YA-OK v1.40 kernel with ext4 all lagfix enabled. So today I had to go for 500 km and I choose SGS to navigate me (I'm using Wisepilot as navigator). BTW, the test was made in Denmark, Scandinavia.

You might wonna take a look one of my old posts here:

http://xdaforums.com/showpost.php?p=9447294&postcount=123

While driving, I was monitoring "GPS test software" to see how good SGS would maintain a sat.lock and at what S/N ratio it would perform while I was changing the settings constantly.

I have now reached a conclusion which very clearly gives me the best result. And funny - I'm almost back to where I started (see old post in link above). Just to refresh, with new setup, here's what to do to get SGS rocking as GPS navigator.

With these settings I constantly have 8-11 sat-locks no matter where I'm at! Next to that, SGS is now even very fast at locking sats while driving. It's pretty amazing how good SGS actually are. So try it out and see if it works for you too.

> Open SGS tools (download from Marked)

> Go to "Secret Codes"

> And find "GPS-Test and settings (LBSTestMode)"

> Click on "SUPL/CP Setting"

> In the SERVER FQDN Type, you should see it set as "Custom config"

> Change this to "AUTO config"

> Go back one step

> Click on "Application Settings"

> Scroll down to "Accuracy"

> Change this to 70 (50 is default). Tried many different values from 20-100, but 70 gives the best result

> Go back one step and "Delete GPS Data"

> Reboot phone

> Go outside (or go to a window) and start GPS Test. Face phone vertical for best reception

> Wait for a solid lock, that is 8-10 sats

> Done and ready to go

One funny thing I noticed. Everytime I stopped at a gas station and went for some coffee, Wisepilot wrote "No GPS signal" when got back (left SGS in car)?! I experienced this every time I went for coffee or water. I don't know if SGS is doing this nor if Wisepilot is the sinner. The funny thing though is the instant I got into the car again, the GPS signal turned on again. Hmmm - I guess the proximity sensor is doing that and maybe/probarly to save some power while not driving. I didn't feel any disturbance from that, the gps signal was on again before I even had started the car.

BUT - back to the beginning. Follow the steps above and (finally) get SGS to work good as gps-navigator.

[Galaxy S I9000 Android Development] Lalaca:
It has already been mentioned earlier in this thread, that the supposed JM9 fix only changes two files -- glgps_samsungJupiter in /system/bin/gpsd and jupiter.xml in /system/etc.

For what it's worth mentioning, those two files in XXJPM, XXJPO, and XXJPA are actually identical (with each other, not to JM9). Possibly all Froyo releases so far. I've been following teriemer's posts about the accuracy settings, and have tried them myself with decent results. There is an improvement, but nothing quite as brilliant as teriemer describes. Perhaps it's just because of where I live.

Due to a few serious errors due to custom roms and flashing, I've had to revert to Eclair XXJM8 several times over the last couple of days, and tested out the GPS on a whim. Two-second lock with 11 satellites -- outperforms any configuration I've tried in Froyo, which is quite a shame.

But I digress. As for me, I'm not too convinced that this "fix" based on JM9 is the universal solution. It hasn't worked very well for me, but it might for other people. Rather than that however, I would personally recommend trying what teriemer has done and see if that gets any better results. I would appreciate some comparisons from other people so that we may collectively draw a more informed conclusion on what works.
[Galaxy S I9000 Android Development] teriemer:
1. Try delete GPS data. And how is your SGS mounted while driving. My SGS is placed in a (passiv) car holder while driving, facing vertical. The holder is placed in front of the mid-ventilation channel, so it's close to the windshield although not directly in the windshield. Actually I do see a small increase i S/N ratios when I place SGS directly in the windshield, ~ +10%. But so far, the extra S/N ratios is not needed and by having SGS in front of mid-vent-channel it's also easily reachable by hand.

2. I get this in 5-10 sec. In clear view I get 3-5 sats with S/N ratios around 40-46 (green bars > 40). When placed in the car holder, S/N's are ~35-42.

3. I'm not running the JM9 fix. I'm using the script the comes along with XWJPA. Don't know if Doc changed this in his (great) customized rom, but I don't think so.

PS - what kind of software are you using to test with? GPS test? Cause if I go testing with Google Maps, I don't get as good results as when I test with Wisepilot. This is although that "GPS test" shows good results!? So I believe that using Google as test only, doesn't give the right picture.
[Galaxy S I9000 Android Development] vBB:
Thanks, it would be nice to try original XWJPA gps because after flashing JPA rom I didn't try its gps but I went for JM9 fix, and now, I don't know which is better. Someone will say that JM9, but another will say that JPA, and now I have muddle-headedness :confused:
[Galaxy S I9000 Android Development] Lalaca:
1. Naturally, I delete the GPS data. But surely not for every run? In my car, I place the phone horizontally, after having read a thread in the General forums about the antenna being located laterally on the left side (our left) of the device. I've also tried other orientations, but the results are mostly similar.

2. My locks take more than 5-10 seconds, on average. Sometimes it'll even take a good 30 to even find a decent number. Even under clear open sky. Signals are also on the weak side. I have yet to get more than two satellites with 40+ strength. Usually it'll be about two or three in the high thirties, and the rest flailing about wildly.

3. I'm not running the JM9 fix either. Not convinced it even helps. I was not aware that there was any kind of "script" that fixes GPS in Doc's rom. If so, I would assume the same exists in Doc's JPO version also, which is what I use. Very few of the files in JPA and JPO are different, and even then, the majority are for regional things. I have doubts that the functionality of these two versions would be significantly different.

4. Yes, I'm using GPS Test. Though for navigation, I've been using Google Maps Brut Mod. Perhaps it is a good idea to try another program and see if that gives me actual satisfactory results. My family and I have been laughing in the car over how slow GM is to keep up with us on drives. Also, the mechanical voice adds to the comic factor.

Anyway, thanks for your reports and your replies!

Initial results using teriemer's settings look very promising using Galaxy S in the UK. Got a fix on 9 satellites on a very cloudy day at my back door whilst having a brew, usually takes ages, got a fix on them in under 1 minute. Will report what it is like whilst driving soon.

So far so good, thanks.
[Galaxy S I9000 Android Development] ghosty_uk:
im also in the UK but getting really bad results, like no lock at all results, and can only see 1 sat, could you do me a favour and post exactly what settings you have, from the lbs menu, and any others that mite be relevent.

i have JPO Froyo, with z4root, and CWM installed, but cant get this jm9fix to install.

incedentially, i talked with samsung about there supposed GPS fix, as i was reluctent to send my phone away for 2weeks odd without a replacement, or lone phone while mine was being fixed, and i can confirm that all they will do is revert the phone back to factory default, so back to JF3, Back to factory GPS settings, i told them all i had done was upgrade the FW to JPO, but not modified the GPS, after going throught the settings over the phone with me, they agreed there was nothing that they could change, the broadcom chip is firmware upgradeable, but as yet there is no better FW than we all have on our SGS, so till a better one comes out, i think the only hope is workarounds or fixes that people come up with. i will however talk with my network, and the place i bought the phone from, to see what they can do.
[Galaxy S I9000 Android Development] teriemer:
1. You only have to reset once, after adjusting the settings, not every time you use the gps.

2. I don't think there is! That is, I have never heard of anything, so I'm asuming that Doc's rom is stock gps sw for XWJPA.

3. Maybe you should try Wisepilot? There is a 5 day free trial you can download from marked. Or you can buy a lifetime version, but you can also buy one week of usage, if that's what you need.

Check their pricing here:

https://www.wisepilot.com/nav11/site/portal.jsp?action=248

It's a really good navigation sw and by far the best I have ever used. Like I said earlier, I'm in no doubt, SGS with Wisepilot will as of now, replace my garmin Nüvi 660.

FYI, Wisepilot just won a big mobile gps-navigation test here in DK! The competitors was Google Maps Navigation, Navigon MobileNavigator, Copilot, Route 66 and Ovi Maps.

Cheers :):):)
[Galaxy S I9000 Android Development] vBB:
I'm not sure if it will work but instead of making update.zip based on JPA, maybe it would be enough when we will replace these two files which JM9 update.zip changed?

[Galaxy S I9000 Android Development] teriemer:
Well that's a good question! I don't know how to interpret Accuracy, but what I do know is that changing the value, affects how SGS locks on sats. If I go with a low value, say 30, I get almost no lock on any sats. 40 is way better, but as my latest has shown, 70 is the best value. I've seen in other threads on the Internet that 100 also have been used, so you might wonna try that out.
[Galaxy S I9000 Android Development] teriemer:
I have exactly the same settings. A quick (small) test gave this result, sitting in my living room while it is snowing a little outside. SGS laying on the couch next to me.

- sat.lock on 7 sats after 30 sec

- s/n ratio 23-34

2. attempt

- sat.lock on 6 sats after 25 sec.

- s/n ratio same as above

3. attempt OUTSIDE, next to our house (holding SGS in my hand)

Interesting topic. My GPS works quite well as it is but theres always room for improvement. It's too bad theres no 'undo' feature. Given that Im pretty happy with how my GPS is already, I wont risk breaking it as it looks like that happened to some others here.

BTW all the people that test their GPS indoors make me both grin and get annoyed at the same time. GPS is not meant to work indoors and results are extremely variable and pretty much meaningless.

You simply can not test a GPS inside. Nor can you really test it by taking it into your back yard. How many sats it sees doesnt say much about how accurate it is nor about how well it will track you in motion. The only way to test how well a GPS works is to take it on the road while driving/biking/walking for atleast half an hour, and use MyTracks or a similar program to review your journey on a map later, and see how accurate it is.

Ill keep following this thread in hopes of a 'restore old gps files' function.
