Which Country are you from Coz I think you. Have installed 2.3.4 manually (that is the europe version) and you are from a different country so GPS is slow and laggish !

I am in Canada and have had lousy GPS performance from the start. I flashed JVR with KG3 (Bell) modem and CSC. GPS works great.
I have tried different ROMs from stock to far from stock and different ROMs act differently on GPS performance.

Sorry to say but IMHO i9000 GPS is bad. You can make some settings mods to get faster fix but that's all. It is somehow working when you have good sats view (it reports good signal with fix from enough number of sats) but when for ex. driving trough inferior sat signal area (streets surrounded by tall buildings, etc.) you are out of luck. Fix position goes to hell.
I've experimented with my old wm phone, i780. It has not so good Qualcom GPS One chipset and I managed to send it's fix using BT to i9000. Guess what? It was ok! Sat fix was reported in i9000 as a poor accuracy but in fact it was ok and stable while using it with maps applications. Go figure! Old, bad i780 GPS shows better then "I can see more satellites with stronger signal and I have better accuracy" i9000 build in GPS.
After this test I connected external BT GPS on MTK chipset. I have to wait ~30 second for fix but after that I have no nasty surprises driving my car through "canyon" streets.

Its got nothing to do with the ROMs. I9000 is well known for its ****ty GPS.

Would you share with us, where you got this wisdom from?
My SGS works perfectly well regarding GPS performance for more than 6 months now not depending on my current location: US west coast and Hawaii it worked great as well as in Italy and various parts of Germany. Fix is usually the within seconds (presuming free sight to the sky). Also the android version had no influence: I started with stock 2.2, upgrading to various 2.2.1, 2.3.3, 2.3.4 and now 2.3.5 (also with different custom kernels).
Where and when did you having GPS problems get your SGS? Maybe there is batch with faulty soldered GPS antennas. However, I don't see a reason why the SGS should have a bad GPS performance in general.

Sounds like all it does is set the settings back to default, basically changing it to standalone rather than ms-based, and it still doesnt work

lol like Endgadget says... it will re-screw up your already screwed-up GPS by defaulting it back to the non-working default settings
Only thing that has ever worked for me has been the Jupiter tweaks on the Dev forum.

I bought my Captivate not long after they were release and never have had an issue with GPS....with Perception ROM I get a lock in less than 10 seconds INSIDE the house...its about half a block off but that's pretty accurate in my book

Dude.....Really? Half a block? That's not accurate man that's about as bad as everyone else's captivate . I'm sorry to be rude but I'm sick of people saying "its perfect" " it locks in half a second to 82 sats with 2 inch accuracy" . Post some proof of your awesome gps then do us a favor and share how you made it work because I'm pretty sure Samsung screwed them all up. Sorry for the rant.........
(I would bet that your "lock" INDOORS would be celltower triangulation and that no birds were actually locked as this is were many people assume there gps works when it in reality suck like everyone else's)
Sent from my Captivate that can't figure out were the hell it is in the world......
I'm really starting to think that the problem is in the antennas. I've never had a problem getting a lock pretty fast, yes lock, not agps approximate. However, it's getting it to keep a lock that is the problem. I always had the dreaded blue circle, or out right gps signal lost. However, for about 3 days straight it has been sunny. And for the first time I tried putting the phone up near the console, back outward and not downward, and it has been perfect. No circle, no lag, no problems. I never had to do this with my other phones. Hell, my WinMo device that I frequently use as bluetooth gps receiver works fine in the passenger seat, or floorboard for that matter. It just seems as if it has to be perfect conditions for the phone get decent gps reception, which to me seems like antenna problems.

The glgps daemon, jupiter.xml, and you! (How to make the GPS behave better)

Hi Vibrant owners!
I made a post over in the Captivate forum about how we can configure the GLGPS daemon in our phones (this is used to control the GPS behavior)
Attached are some update.zips with a new glgps daemon pulled from the Nexus S, secgps.conf and a jupiter.xml configuration inside. The GPS chipset is common among all SGS models, so this should work for you. Please try it, feedback is appreciated!
Sweet!

I know at least one model of Vibrant does (Bell), not sure about the others (CDMA does not I believe)
With the vibrant froyo leaks, we now use gpsd and jupiter.xml Samsung decided to make it the same across the board. At least for the i9k, cap and vib. Not sure aboit the epic and fascinate though

Wow. Your like saying that people doesn't have to fix their gps if yours has been already fixed.
im saying if you've upgraded to a new rom like most here then it should have been fixed. what kind of fix are you expecting a 100/100 Sat lock the instant you turn on the GPS app?

Yeah it should have been fixed, but to some it isn't. Maybe because of the hardware or other issues.

I'm not expecting that, we all just want it to be usable like having a better accuracy.
sorry it's getting late and my brain is not fully functional ^_^ though it is sorta confusing how the same hardware can produce different results with the newer 2.2 roms.
It's not the same though.
The antenna got revised in October 2010. See the post about the gps fix in the Vibrant general forum.

It seems the newer antenna did fix it - the older design is unreliable so "identical" hardware can have different GPS performance depending on how much the connection has worked loose.

if you compare to HTC model like HD2, you will see that vibrant is very slow altough gps is fixed...I once use htc hd2 with MDJ mod for android GPS is real fast, never more than one minutes from start ( case compared when u totally delete gps data) I don't know how HTC did it...just for your guy to concern
My GPS has never worked and I've tried every ROM and every fix. Sure I can get a lock on 8 of 12 satellites, and I can easily get 10 foot accuracy. As soon as I try to use Navigation, it sucks. It'll jump around by a few feet here and there, and that's enough to totally throw off the navigation. All of a sudden it thinks I'm the wrong street and its telling me to turn around.
im sorry guys, that sucks. mine has been fine for a while now. and i navigate quite a bit as I am new to Cali. Initially it truly pissed me off when I was on 2.1, telling me i'm staying on the highway when i infact took the off ramp etc... lol. I'd get a replacement.
Can anyone ever say the word GPS without sending everyone into a pissing frenzy?
BACK ON TOPIC:
OP which one do you recommend starting out on for us Vibrant owners?
I highly.. very highly recommend Sombionix' Nero 3. I've used a lot of roms and this one is very very fast. And I usually refrain from saying "fast" because most phones are initially fast when new roms are installed but this one definitely deserves it even after massive app installs and use.
I tryed out the google version and it killed my GPS it sees 12 birds but won't connect to any.
Which do I install? I have a Tmobile Vibrant. You have 3 files listed. Thanks.

[REF] Gingerbread GPS fixes and the vibrant - read before posting GPS fix

I'm seeing tons of GB GPS fixes for the vibrant even though most will not work.
I saw GPS files for the bell and virgin vibrant posted here and files for the
telus Fascinate 3G+. These files will not work because the vibrant carries a different hardware radio.
The T-mobile US Vibrant is a special variant as our phone is the only galaxy s device (other than the SGS4G) that has the 850,1700,1900,2100 bands, all other galaxy s variants have 850,900,1900,2100mhz bands. Our vibrant requires 1700 3g because thats what tmobile US uses for 3G, because of this difference we need a different hardware radio, That's also why we cannot use i9000 modems on the vibrant for tmobile US The bell and vibrant are just rebranded GT-i9000's and the Telus Fascinate 3G+ looks like a vibrant but may even be more similar to a captivate because of the hardware radio. Even though they may have the same styling or name it does not work because of the hardware radio.
The Captivate has a near identical (FM Radio is not present) hardware radio that allows it to use i9000 Modems and GPS files, same with the telus fascinate.
The vibrant and the SGS4G have different hardware radios to support 21mb/s HSPA+. These two hardware radios are similar enough to allow GPS to work but remain modems non-functioning. Romans GPS fix worked but had long lock times and poorly working compass.
Heathens Gingerbread gps fixed worked on the vibrant on 2.2 very well but fails on 2.3. What I think is the vibrant may have hardware similar enough to allow some files to work on one version of android but maybe completely useless on another version of android.
Just so you guys know,
Bell and virgins vibrants ARE NOT T-mobile US vibrants
Telus fascinates LOOK LIKE but ARE NOT T-mobile US vibrants
International galaxy s vibrants ARE Bell and Virgin Vibrants
Rodgers captivates ARE IDENTICAL to at&t captivates
The i9000 galaxy s and the bell and virgin vibrants HAVE NEAR IDENTICAL RADIOS to the rodgers and at&t captivates
Tmobile US SGS4G's are SIMILAR to the Tmobile US Vibrant

You're going to have to explain why the cell radio affects the GPS. There's a different antenna and GPS is not controlled by the radio firmware.

What I believe is that GPS hardware is some way tied to the cell radio. Like maybe the i9000 GPS is not compatible with the vibrants cell hardware.

Just one tip philliple...when trying to sound like you know something never use the term "what I believe is". Don't get me wrong I am guilty of it also. Instead you might say "correct me if I'm wrong but..." Gives your statement an air of confidence and knowledge yet gives you an out if in fact what you said is incorrect. And I do know how old you are, we all do so respect there.
That said you are correct the GPS does require data in our case cellular data. While we can use the gps without cell data, on a wifi connection for instance, because the GPS is on a phone the code for the drivers would be written to connect to cell service. Therefore GPS files, such as drivers (some files that don't require code to the network will work, such as GPS conf.), can not just be pulled from any phone. This is why the files pulled from the Vibrant 4G work and the ones from Captivate do not.
Here is a link to a little light reading for anyone that wants to learn more about the GPS on their phone...http://stackoverflow.com/questions/33637/how-does-gps-in-a-mobile-phone-work-exactly Pay close attention to the AGPS section. This is what our phone uses. Never-mind the fact that whats written in the link was posted a couple of years ago because it is still the same priciples.

Not being rude but all you did is give a long winded "our phone is unique" statement, something that anyone who has looked at this forum since getting a vibrant would realize...
Not really sticky material. Nice info though. Maybe talk the the author if the vibrant bible and you can get a link in his thread for info.... Still doubtful.
Btw, the current v1.5 gps fix from strictlyrude for the cm7 variants seems to work great for me outdoors.

I don't believe this is correct. Our phones have GPS hardware are capable of independent GPS, that is GPS without data assistance for a lock. It takes quite a bit longer without AGPS, but it is entirely possible. Try changing your GPS to standalone mode, disabling all other location services (via WiFi and via cell tower) and putting it into Airplane Mode, then launch Google Maps. You can obtain a lock.

[Q] Optimizing GPS reception

Yes, I know it has been discussed before. However I didn't understand what is the most recommended software solution(I have tried the hardware one).
As of now I didn't touch any settings, except changing the NTP Pool to my country.
If it matters, I'm on Infinitum Rom.
GPS aids, the donate version. Bad UI, but excellent results. Always works wonders for me. There's also fasterfix, but it's not as extensive.

Is there a hardware fix for the GPS on our captivates like there is for the Vibrant? Searched a few pages, and didn't really see anything.

2. where i897 is GPS antenna? if you can mark the location of the antenna gps in the picture.
thank you for your help.
By the way I'm Ukraine.
who may come in handy today an educated bet Founded location zhps antenna on i897. Well, then disassemble the phone and the antenna to be under the speaker if the speaker remove the antenna located in the top right corner of the board. Who can come up with how to enhance signal reception, write.
