Hmm, I did try and track myself on the bus this morning and it did seem to have a problem finding me - it kept flipping between near where I was and about halfway back home. Used it walking down the street and again it didn't seem to be very good at nailing where I was (HD2 seemed much better). I've enabled location via cell location as well as GPS, so I'll see if that makes much difference.
This doesn't sound too promising :/
I've been using my iPhone 3G to track my runs when I head out, and I assumed the Galaxy would do just as good (or better!) at it. Hopefully it's something they can fix with a software patch and not a hardware problem...

Did you get it from Expansys? I am trying to find out whether it is just a batch or it is a more generic issue.
I too am seeing poor performance with the GPS. Seems to be a hardware issue.
I did a test over the weekend comparing my Galaxy S with a friend's HTC Desire. Using one of the many GPS utilities the Desire was consistently seeing and locking more satellites when stood in an open area outside. When running Google maps and showing the current location I found that the "accuracy circle" (for want of a better description) was growing and shrinking several times a minute causing the map to zoom in and out.
I've also noticed that the compass is almost unusable and showing a much lower signal compared to the Desire. I did perform the figure of 8 calibration several times.

Nope, got mine from Handtec. Really hope it's just a software issue that can be easily solved! Also noticed that google homepage in browser keeps saying I'm in China?!
Think I've read somewhere that samsung galaxy (the first one + the spica) have a broken gps driver causing such issues...don't remember if it was in sportypal forums or for a similar application. Very sorry to hear it's not fixed.
Nope I tried out google navigation at the weekend and was really impressed by the accuracy, it made my old tom tom look really bad.
So can we say that GS favours google navigation?
Can anyone confirm that?
This is very worrying, GPS is important for me, I don't want to have another N97 on my hands... fingers crossed it's a software issue....

I've not noticed any problems in Google Navigation. It found me almost instantly, and was so accurate in terms of showing me where I was while driving that there was almost no perceivable lag.
Whatever people are seeing it very unlikely to be a hardware issue, most phones use GPS chips from only 1 or 2 suppliers, its much more likely something temporary like a driver issue.

TravUK, have you tried google maps - did you have any problems with it? (although I assume navigation would be using the same data to find you)

Yep, Maps works fine, including latitude. Also used Waze which took a little while to get a fix, but was also ok.
Well the journey home was much better! Probably helped that I was sitting by the window on the top deck of the bus, but I managed to get a much better fix, using both google maps and navigation. It wasn't like 100% accurate or anything, but certainly no worse than my hd2. Hardly got the large blue circle, but it did think I was in a field a few times, but that's to be expected. To note, didn't seem to make much difference whether I had both gps and cell data selected, or just gps.
My gps works perfect. Google maps finds it instantly and waze and speedometer apps work fine too. Localization is spot on. The gps even connects when I'm inside the house wich my Diamond never did.
I tested Navigon, which can be download from Market for a tryal period of 30 days now, and it working great on my Samsung i9000
it may be a firmware issue , everyone who is having problems should post the sw. version for comparision with others
Comparison of Galaxy GPS and iPhone 3G gps.
Hey everyone,
There's been some discussion regarding the "quality" of the GPS function in the Galaxy S, and after testing it out today, I sure hope it's a software bug or I'm going to be very disappointed.
This is my run as recorded by my iPhone 3G (with Fitnio): http://dl.dropbox.com/u/810054/samsung_fail/Picture%203.png
Now this is the same run as recorded by my Galaxy S (with RunKeeper): http://dl.dropbox.com/u/810054/samsung_fail/Picture%202.png
Take a wild guess which one actually reflects reality. Can anyone shed light on if the new "leaked" firmware fixes these problems?
They're all based on standard chipsets so its unlikely there's anything wrong with the GPS receiver itself. I hope it gets updated soon as it seems to be affecting a fair number of people.
Okay so now that I have my vibrant I tested it out (only a few times) but I did test it in different applications, websites, and maps and navigation. Yes in the gps and compass apps it doesn't pick up at all compared to my slide BUT in every other application, on google where it finds your location, on yelp, movie phone, maps, and navigation it finds my location each and every time. It doesn't get me lost, it doesn't show me going in a different direction, and it doesn't show me somewhere else.
What if the configurations or settings are different with samsung, what if the third party app is not completely accurate? Why else would every other program find my location if the app says I am not found by even 1 satellite? I think the"fix" is just a change of setting that helps the app not the gps or the phone.
Time will tell but for me it us working fine for now.

Well you can do gps tests within the os that say basically the same thing...
Ive used my gps with google navigate nermous times with no problem. in fact, it guided me on a 160mile trip just fine... What problems are people having with their gps?
Well, I've only had the phone for a day, so I'm still getting used to the quirks coming from a G1. GPS so far is the biggest disappointment. Android has been pushing location based stuff since the beginning, so the lack of a solid GPS is really screwing up some of my favorite apps. Locale for instance, it's worthless. It can't ever find me. The G1 always worked fine with it on Donut, Eclair, and Froyo.
Google Maps is the ONLY app I have that seems to even be able to get a rough idea where I am, and even then its circle is pretty big, about 4 city blocks. That's not GPS, that's network location, and it's fine for what it is, but not good enough when there aren't a lot of cell towers around. At home, it puts me out in the middle of a corn field. All the time I'm in maps, the GPS icon is up there blinking at me, telling me it can't lock. I've seen it work a couple times, for a short while. In GMaps and in GPS Test. But it takes a LONG time. The G1 could get a lock indoors in about 10 seconds. The Vibrant takes minutes, even with the A-GPS turned on in the test menus. That's insane. And it's not any better outside with a clear sky view. That might be acceptable, if it could hold the lock, but it doesn't.
Even stranger, in GPS Test, I get a single colored bar saying it's using that signal. There are 6 more with the same or higher signal strength being ignored. Very odd. Something is wrong with this GPS. It could very well be software, but Samsung needs to get on this and fast. If I can't find a way to get acceptable GPS performance within my 14 day period, I will likely return it. That will really suck, as otherwise I really like the device, but I need a decent GPS.

This has been my experience as well, and I found the same thing when trying a friend's phone. If only T-Mobile/Samsung would acknowledge that there is a problem and say they are working on it...
No problem here
But as I came from the G1 I use Google Maps exclusively. I haven't had a single problem with it. Inside my house I can get a fix on my location on the map, exactly where it should be. Are you guys using the TeleNav?

I have the same issue... I can only ever lock on to 1 sat. This is not right. My G1 would lock on to many birds.

I wonder if GPS Test is either wrong about that, or more likely, getting bad data from the OS or GPS driver. IIRC they are just parsing the NMEA data from the GPS driver, so "garbage in, garbage out". You don't get 20ft accuracy with 1 satellite being used.
I fooled with the settings in the "GPS fix 101" thread and got the thing working decently. Took a number of tries, and we'll see if it keeps working over time.
This really is something that TMO and Samsung should acknowledge and at least promise a fix for. Preferably with a close release date. And we shouldn't have to wait for Froyo either, get us a fix for JUST the GPS and a lot of people would be VERY happy. Well, that and the compass, that thing is even more worthless than the GPS before the fixes.
For the poster with Google Maps working, did you try with network locations disabled? Is the GPS icon in the status bar flashing or solid? If it's flashing, you DON'T have a GPS lock. Maps seems to be really good at using the network location stuff. I also enabled Skyhook in the GPS settings screen and Maps really seems to like that. Doesn't help with GPS performance though.

Wow.. that statement was idiotic. Maybe you aren't having the GPS issues that others are having but this thread is helping me debug and decide weather or not I'm keeping the Vibrant or returning it.
You guys are not alone. There is obviously something wrong with either the hardware, or the software. Either way, the buyer's remorse period is halfway through, and neither company has said so much as a peep.
I will definitely be returning my device by the time the remorse period expires. What a shame that would be, because I really love this screen. All it would take is for T-Mobile and Samsung to acknowledge the problem, and state that a fix is on the way.
Here's my post, detailing my contact and findings with the two companies.
It's been a few days now, and I've heard nothing back. Never a good sign.
EDIT. Got it working
Care to share?
Is anybody's working to satisfactory? Or am I the only one?
I never really used GPS till I got this device and only from the complaining here had it really got me interested . Although I use GPS maybe 3 times a year, I've made it a point to use it every drive I take to see if its still working.
I always get a lock within 5 seconds to at most a min. Stationary or moving don't matter. I've never had my phone say location not available.
My phone always sees 11 or more and only locks on to 3 or 4 once it locked 7...
When I hit navigate to then a destination it instantly finds me and routes me. While driving it every now and again has a blue circle but that's usually during lots of overpasses turns on freeways and etc. For the most part it has no circle ...
I will admit every now and again it'll lose route and not reroute so I back out and hit navigate again and back to navigating.
Its even found me in portland Oregon in the city.
So my question is, although GPS could be better I.e. faster lock, more birds to lock on and tracking while moving, it still has served its purpose and found me my way a few times when I'm lost.
On the way home I will use it again and it will find me almost instantly and navigate me all the way home...
Am I lucky? Or do others work good enough to get around, yes could be better, but is yours good enough like mine to where even if they don't fix it, its not that big of a deal cause for the most part for me it works?
Another thing is I'm beggining to think its hardware and software. Reason is messing with the settings does improve or have different results, but on the other hand the gps fixes seem to give everyone different results and why would Samsung release them all with poor GPS just to supposedly fix it in a few weeks/ wouldn't it have been easier to fix then ship em out?
Who knows, no one is for sure, but I just want to know who's is atleast satisfactory like mine? Maybe I just don't have high GPS standards cause I don't use it to get 1 meter off. If I'm atleast 50 meters away I think my eyes and brain can help me find the other 50 meters.
So are you satisfied even though it needs improvements? I am. I don't think it needs fixed, but as Samsung says "optimized".
Please no there are many GPS threads comments this is a little different ...
Is your GPS useless, or does it get the job done, not how you wish, but gets it done?
Edit: this is no gps fixes. Pure stock.
Mine isn't as terrible as some people say on here, but there are definitely problems. Latitude, for instance, often falls back to network location even with a clear view of the sky. Driving, it will randomly drift far enough that the GPS goes to rerouting mode, trying to bring me back on course. And there are times that it just refuses to get a lock for 10-15 minutes, though luckily that doesn't happen too often. Definitely worst GPS performance than my G1.
But, all that being said.. Not so bad that I'm really stressing about it. I'll give Samsung/TMO a few more weeks for an update and hopefully they patch up the issues with Froyo. If not, or if the update gets delayed, I'll start tinkering with the fixes from the forums.
mine works fine too. quick to lock, navigation works perfectly. i was locking on 3-4 satellites last time i tried.
it's not very good indoors, and often has trouble determining location, but outdoors it has been completely satisfactory.
this is all with gps on, and use wireless networks off, btw. completely stock, and the compass works fine too.

I'm the same, I don't use GPS that much, but when I do it works fairly well. Its not the best I've used but it gets the job done. Only once when I was driving on the freeway could it not lock on.
I remember reading that a GPS fix leaked for the Captivate and it seemed to fix the issue. And the new SGS phones coming out for Verizon and Sprint seem to have better luck with GPS.
For me too GPS locks 95% times. However Navigation is the only application that crashes my phone once in a while....and I dont like that
Mine seems OK, with the light use I've given it. Haven't tested it out with route-tracing software like some have -- but for just getting an accurate lock, it seems on par with other phones I've used. (Maybe a little slower to lock.)
I had tested my GF's Samsung Moment alongside my Vibrant many times and the Moment hooks to GPS quickly and consistently. I cannot think how Samsung could implement an inferior GPS in their flagship phone!
My gps works flawlessly, when I read all these threads its hard to remaster because everyone I use gps it takes a matter of seconds to lock in and route me to my destination. Even in my area of living which is outside of the city it is very vet close to where I actually am and even right on. I would be frustrated if it didn't work as I do use my gps every so often but it is precise in my experience and I'm very happy with the final product.

I now have two GPS's in two of our cars. The primary reason for buying a GPS a while back was so I could meet up with guys that I often 4wheel with in various locations. I would get lost when somebody told me to meet them in a city that I didn't know very well. My wife saw how handy my GPS was and took it. I finally got a G1 and it was used as a backup in case the wife wouldn't let me use "My GPS".
Anyways fast forward a year or so. We bought a second GPS for her car. Why because she got the new one of course.
Now that I have 2 GPS's in my cars my phone has been well a secondary or I should say hardly ever used. However when I'm on foot and I get backwards its always been nice to know I could fire up my GPS and find my way somewhere. Lord knows I've been lost a few times in down town Seattle. Wandering around and firing up maps and then using the by foot option has saved me many times. Sure it didn't have to be accurate since all I needed to know was do I walk 3 blocks north then 1 to the west or is it 3 blocks to the west then 1 block to the north?
The Vibrant GPS works when I need it, but honestly I really wish it was a bit more like the G1. Its nearly useless when I use CardioTrainer and a few more apps.
I have had my Vibrant for about 45 days and the GPS has been awful since day one. I have tried some of the fixes which did help a little bit but I still have problems. The GPS cuts on and off so much that Cardio Trainer is pretty much useless most of the time. It has started to freeze on me while attempting to use Cardio Trainer today, which necessitated pulling the battery. The GPS normally shows me about 2 of 3 miles from where I actually am. The compass is just about totally useless. This is a wonderful phone and would be a fantastic phone if the compass and GPS just worked normally. I am starting to be concerned with the phone starting to freeze up as it has not done that in the past.
Mine worked great for a few weeks. Even though it wouldn't lock more than 3 or 4 satellites the performance was completely satisfactory. Then it got a little quirky with accuracy and my position started jumping around a lot. Then it started positioning me miles from where I actually was sometimes, causing Maps to lock up, causing the entire phone to lock up, and generally being unreliable.
Over the past week or so I've had to reboot the phone half the time I try to use the GPS in order to get it to work. I can usually get it to work at a satisfactory level eventually, but it's far from painless. I haven't tried any of the "fixes"...my GPS settings are stock.
On my first phone the GPS and phone in general was a disaster.
Once returned, my second phone is "ok" for driving assistance use, it takes awhile for a lock but it works. But I otherwise leave GPS turned off or else my phone will randomly shut down/reboot.
With trepidation I applied a no lag fix and it has turned my opinion of the phone from "meh" to wow (even though I was not even sure I had a lag problem, but little did I know).
So if GPS gets fixed and 2.2 deployed, and assuming 2.2 solves lag or a no-lag fix is implemented for 2.2, then I will be very happy. But it sure seems like a bit of grief to get to that point. Anything goes wrong down that path, and I'll focus on HTC or other devices... cause for similar past issues with hardware I never buy HP

Add a compass fix to that list and I'm there with ya.
After applying the gps fix I haven't had a problem since. I use the gps daily and have only had 1 restart. Had my vibrant since day 1. Maybe I just got lucky.

I completely understand the need to get the GPS fixed, but I have to honestly ask...why do so many people seem so worried about the compass?
Are there that many of you out there that wander around using the compass all the time ? Is it because of apps like Layar ?
Using a smartphone as a compass/gps on a hike is useless if you plan to be out more than a few hours so that can't be it.
Is it just the principle of the thing ... that they provide the feature so it should work properly out of the box?
I'm not trying to be a wise ass here...I'm honestly curious.

In a word: yes.
While I don't use Layar much, it would be great if it worked. I've tried to use Google Skymaps several times and gave up due to the compass completely freaking out when I hold the phone up to, you know, look at the sky. It's nice the have a working compass for Google Maps...even if it's just for street view. Yelp taunts me with directional functionality that doesn't work, and I could go on. In general I'd like to know that apps that use the magnetometer to detect orientation (and who knows what will come along that will use that functionality) will work. I don't think that's too much to ask.
Now, I also do a lot of city navigation on foot, and having a compass to figure out which way to walk when I come up from a subway on my way to a meeting is a huge help. Seriously. At that point I don't have a GPS because I've been underground.
I've used Android devices (like the G1) that are old-ish, and I've used Android devices that are not considered high-end devices with working compasses, so yeah, on principle I expect my high-end $500 device to work at least as well as they do. Had I known about the worthless compass before I purchased the phone it would have given me pause...I probably would have at least considered another device. It bugs me that such a simple piece of functionality being broken will prevent me from using apps and features that I'd otherwise find useful on my expensive device.
Now I have a Swiss Army knife with a broken saw blade. Yeah, it's just the saw blade, but I paid for one with a working saw blade, dammit, and it wasn't cheap.

that sucks dude. i just noticed what you were saying about google sky map, mine was tripping out for a little while but then it finally settled down. can't really tell if it's pointing in the accurate direction because it's daylight
my compass has worked just fine on maps though. it always points me in the right direction, and even the compass on the "gps status" app is correct, birds locked on or not

If I hold the phone "just right" I can usually get the compass to work ok in things like Maps where accuracy isn't terribly important. It's still painfully slow compared to other Android devices I've used, though. Most I've seen have nearly instantaneous compass updates when you turn...on my Vibrant (both of them) I have to wait a while for it to settle down before I can tell how it's reading. When I hold it in an odd position...like you do for Skymaps...it's all over the place. Sometimes it works, but it's hard to tell unless you're manually keeping track of which way is North, which kinda defeats the purpose, eh?

This post is intended for troubleshooting and finding solution to the GPS on Galaxy S ONLY
For arguing, dissing, and the sort, please go in this thread:
http://forum.xda-developers.com/showthread.php?t=722476
Post here your findings, your solutions and your attempt at finding a better fix for the GPS.
If you happend to try something and it doesn't work, please state it also
And keep away from none relevant facts
Here's my finding so far:
The way the device is put (in a pocket or in a car) seems to greatly influence the signal and the streight of it. The antenna is (apparently) situated in the upper left part of the backplate, just outward by the Sim card. if the signal is obstucted or not facing the right spot, it might get a hard time getting a fix.
Someone might confirm this and I will try to record a couple of track while the device is place differently in my pocket to confirm it has an effect.
I'm using it for:
Mostly keeping track of my working with Sporty Pal. As for now, I get an error rate of under 3%, wich is acceptable as far as I go but a lower rate would certainly be taken
As for navigations and Trapster, it's still pretty "on the spot", I'm drinving a 1995 Acura Integra, so I don't know if the insulation of the vehicule could affect the signal and the device is always on a spot where it "sees" the sky.

Uptime about 16h
Known Workaround
1-TrackerBooster (available on the market)
This is a booster for the GPS, if you have issue where the position goes all around randomly, try installing and running this apps before running your GPS application. It was tested with SportyPal and gave amazing result.
2-BlueTooth GPS, some users have tested this solution here
http://forum.xda-developers.com/showthread.php?t=818688
you can most likely find one under 30$ and it should resolve the issue.

should work better. (Does not work on Froyo JPM).
well lets start with listing the known solutions
like for example using the external GPS receivers via Bluetooth
there are several tested and working Bluetooth GPS apps by our members in the Galaxy S I9000 Themes and Apps section of the forum
Thanks, corrected!
I did start a thread posting 2 videos with "solutions" where users can actually see those "gps solutions" in action eliminating any kind of speculation (seeing is believing), but the thread was removed with no warning or explanation...
Anyway here are the videos:
http://www.youtube.com/watch?v=BM2gm5DAOjM
http://www.youtube.com/watch?v=p6QnNMxuCig&feature=related
In both videos, sgs's gps performance is flawless with or WITHOUT any assist (2nd video)like agps or aid of from an external bluetooth gps receiver (like in the first video).
In the meantime I already did 5 more driving tests, always running Motonav and so far no need for using my external bluetooth gps device.
The firmware is JPH, not customized and no lag-fix of any kind (not needed)

Right, I dont want to start an argument and the video's above are very usefull.
But I think it's possible that the navigation software you are using is optimised and more than likely programmed to keep you on the road, rather than drifting all over the place.
I noticed this while in the car earlier. When using "google maps" my position was often miles out and all over, however when using the "google navigation" it kept me on the road and appeared to track my location really well.
So from a navigation by road point of view I don't have a problem.
So i thought a compare of SNR levels compared to a differant phone might help, so i took a photo of my sgs running GPS Test, next to a Orange Sanfrancisco/ZTE Blade. Both are running froyo, both had gps and a-gps turned on. Both were next to eachother, both were left to settle for five minutes after the apps were started. Both were connected to exactly the same wifi connection. Finally the ZTE was connected to 02 network, and the sgs is on orange.

From what you can see in the photo's the levels are pretty similar. Maybe with the sgs gaining a higher level on average compared over all satelittes it found.
Now with both devices sat next to eachother this is fine, however on moving around the sgs kept loosing its lock on the sattelites and stopped using them, however the blade kept its lock better. The blade seemed to keep its lock even with the SNR of some satelittes getting very low, however the sgs lost its lock at a far greater snr level.
Now I don't know a great deal about gps, but it seemed to me like the sgs gave up its lock far easier than the blade. Maybe this is what is causing our problems, maybe once it has given up this lock, the sattelite information is decreased causing a less accurate location.
Now I don't know how this could be rectified, but I imagine it is either driver related, or maybe some code in the actual gps chip itself. But im not 100% sure. It would be great if someone more knowledgable than me could give us their two pence.
betoNL: Thanks for the TrackerBooster apps, I've done a run this evening with it and it's trully amazing!! With it, I don't see any "jumping around" issue at all. If anyone has any issues where the position goes "randomly", they should try TrackerBooster.
SkinBobUk: Thanks for the sharing, I'll try GPS test and post image with and without TrackerBooster to compare
personally iv used the gps quite a lot to navigate around the U.A.E and most of it was using the trapster program to keep an eye on radars/speed traps while driving.
testing the gps is totally random, the results are never improving, simply random.
sometimes id get a fix in seconds and other times it wouldn't (guess its an SGS thing), playing around the settings i found the best combination to be...
Session Type: Tracking
Test Mode: S/W Test
Operation Mode: MS Based
Start Mode: Hot Start
GPS Plus: ON
Dynamic Accuracy: ON
Accuracy: 500
Use SkyHook: ON
Use PC Tool: OFF
tho accuracy is high at 500 the test showed better lock on gps and a max of 20m error, with accuracy i found out that the smaller the number , the harder it is for gps to get/maintain a lock ( even with high SnR numbers between 25-40 maintaining a lock was hard, the SGS was jumping around which gps to lock on ) and with a high number it would maintain the lock for a longer period of time. Highest i found was 500 and anything beyond that wont even activate the gps when running the get position test.
last weekend iv been on a fishing trip and needed the gps help , it was working amazingly accurate up to 5m error thruout the trip but every 5 minutes or so it would hang/freeze and the solution was to restart the program which was fine by me.
Conclution is that GPS is simply unreliable being in its Random State
(when under a lot of testing the gps would freeze/hang and a phone restart is needed to get it back up {switching gps off and back on doesn't help}) , i found a small app in the market called GPS optimisation by octy which should optimise signal reception but for me it doesn't but rather fixes the gps and gets it back from its frozen/hung state - time it takes to restart the phone = more than a min but this app does it in seconds
hope this accuracy options helps you people out in getting better/longer locks on gps
I also use tracker booster with sportypal combined, it provide great accuracy

got the same feeling/issues/feedback when i tested the gps. trackerbooster and equivalent apps didn't really help me with the "lost lock too easily" issue
when its locked it seems to work fine (accuracy wise), but it keep losing the lock of all sats at once every now and then
On my SGS I have found that if I hold it with the screen vertical or tilted back slightly I get significantly higher signal than if it is horizontal. Also portrait is better than landscape by 2-3 dB.
Please write your firmware / Rom info and if it's stock or with Root/Lagfix
Currently, the only conclusion I can make is this combination is running flawlessly:
Accuracy on 20
Rom on JH2 (Stock for BellCanada)
TrackerBooster installed/enabled
NO lagfix
NO rooting
Latest run with this combination is right on the spot so far as jogging, I can clearly see where I cross the street or when I ran into a parking lot.
Imho, there are no special fixes or special settings to improve sgs's gps performance, just some "assist" or a-gps if you will.
There are all kind of a-gps possibilities besides the "standard" one that uses cellular towers wich in many situations can be unreliable.
Other types of "assist" are implemented by using the right software to simply download "fresh ephemeris data and injecting it to accelerate the first lock during a cold start* .
The big issue (again, in my opinion) is WHY the majority of the smartphones nowadays (and with that I mean NOT ONLY the sgs), are equiped wich gps chipsets that will require 'ASSISTING" ??
A couple of years ago, experts of the GPSPassion forum performed a comparison test between devices equiped with a sirfstarIII chipset and others with a-gps and the conclusion
was as I quote:
CONCLUSION
While the Qualcomm gpsONE chipset of the HTC P3600 performs better than on the Siemens SXG75 Linux Smartphone where it could take 10+ minutes to get a fix, it remains much less effective than the SiRFstarIII chipset used on most current GPS PDAPhones . This comparison also shows the impact of GPS Assistance (A-GPS) to get a fix and reduce the time to guidance. Even the "offline A-GPS" of the Mio A701 helps significantly, while the "Full A-GPS"(SUPL) of the Orange SPV M650 will bring extra speed and more so as the conditions deteriorate.
Overall, the GPS performance of the SiRFstarIII PDAPhones is excellent and does not pale in comparison with the performance of dedicated GPS systems like the TomTom AIOs as seen in this comparison done in the same area. Let's hope the upcoming GPS PDAPhones like the HTC X7500, the Eten X800, the Mio A501, etc...will maintain these high standards.

Well, their hope was is vain, cause even the very expensive so called high-end smartphones,
just stoped using sirfstar III chipsets or equivalent and using a-gps dependable ones,forcing users to find, configure or re-invent A-GPS solutions!
The good news (at least for me) is that the gps chipset of the sgs is LESS A-gps dependable than many other smartphones I tested, and even if it wasnt, I can always rely on the aid of my external bluetooth gps receiver(equiped with a sirfstarIII chipset), since programs like "bluetooth gps mouse" and "gps provider" work like a charm on the Android OS (see my first video: http://forum.xda-developers.com/showpost.php?p=8876869&postcount=5).
Another issue is that Google maps could be unreliable for car navigation and of course unreliable for testing as well: http://forum.samdroid.net/f9/maps-navigation-bug-missing-value-gps-accuracy-1247/

In the images earlier in the thread where someone posted two pics, one of the SGS and a matched one with another phone, the SGS seemed to be consistently 3 to 4 lower on the same satellite at the same time. That would likely be a hardware (antenna) issue, and could it be that is the problem with fluctuating results, that the reception is just too flaky?
To me, that is an eye opener. Id like to know if it would be likely for the software to cause a reported different in signal strength. You would think that the reported signal strength would be unchanged from the chip, through the driver to the reporting software, no?

Thank's for the input, but in wich conditions and where those pictures were taken? Are they taken with a camera or are they screenshots?
What I can say, eventhough I find OFFLINE software car navigation more reliable (and I always use up-to-date maps) they are not "optimized" to "keep me on the road" as you speculated, is more likely that the full A-gps (SUPL) on the Orange Sanfrancisco/ZTE Blade is better optimized than sgs's but then again that's speculation.
This discussion can go both ways:
A) The complicated way, mostly based on speculation, for instance: saying that Samsung or Google cannot handle A-gps protocols, I mean wich SUPL configurations to use, in wich regions, by wich carriers, with wich software and so on....
And: Nokia wants you to use the server "nokia.supl.com" on their phones and Google wants you to use "supl.google.com" on their phones, but how the different carriers, in different regions and the various software are dealing with those configurations? And again how to deal with full a-gps? And why do we have to( see my last post)?
B) The easy way: Just get a external bluetooth gps receiver (with a sifstarIII chipset or better) connect any gps software using "gps bluetooth mouse" or "gps provider" apps to it and get over with it !
I rest my case
P.s.- On my last 6 trips didnt even have to use the external gps, just the internal one...it is doing just fine;
i must have a specially blessed sgs or Holland is just a better place for gps navigation

A-GPS is only necessary for the initial lock and yes, Navigon, iGo et al are optimized to keep the position on the road.

A simple test is to drive down the road using google maps, then drive back using google navigation. The differance couldn;t be more clear.
They have to be optimised to keep people on the road, if not then there is a problem with google maps, and i doubt that!

Actually, Google maps isn't perfect (if you check the satellite feeds, you'll notice the roads wont always align perfectly) , but anyway, you are correct. Car navigation apps do special work to allow large errors to be made by the GPS without freaking out. That wont work with normal tracks.
Testing consistancy
The problem here is that the testing must be consistent. What is needed is an application to:
1) Create tracks at the highest resolution possible
2) Record speed at many points
3) Maybe have OBD2 integration, so we can match REAL vehicle speed with the track
4) Record the satelites/snr values constantly on the track.
5) Have test scenarios, that takes into account the environment and speed. Because when walking at 1hz, updates of GPS are done every 2-3 meters, but at 100km/h, it's every 28m. We don't even have enough info to know how often updates are done, and some tracks are created by people who are in dense skyscraper ville. We simply can't compare the information at the moment
6) By comparing car tracks to google maps, you could even do some basic GPS benchmark type stuff!
Start with a proper testing procedure, create a means of gathering PROPER information, then we can finally start actually testing how reliable people's phones REALLY is! At the moment, we are simply comparing OPINIONS, because there aren't specific tests to follow. There is nothing scientific about this thread until a process to accurately compare results is created.

You raise valid points, but it is unrealistic to expect this kind of controlled testing from an Internet forum.
What I can tell you from personal experience is this: when I run Nexus one with Google Map and SGS with Google Maps at the same time while driving from work to home (or vice versa) the SGS consistently loses lock for about 30% of the route. When I go off the motorway it consistently thinks I am still on the motorway for about 10-20 after I have left it and then needs to reroute. Both the Nexus and SGS are running Android 2.2 and the same version of Google Maps. Nexus One (and an iPhone 4 which I also have) have none of this problems.
The point I tried to make earlier in this thread, admittedly not in the most polite way, is that all the settings discussed here are for AGPS. They only affect the speed of initial lock, not the functioning of the GPS itself. That is why none of the so called "fixes" work for people with non or poor functioning GPS. All that Samsung has done in various ROMs is to tinker with AGPS and also smoothing and predicting of the path while driving; they have not been able to address the underlying issue, which is the inability of the GPS receiver to keep GPS lock.
This can easily be tested by using something like "GPS status" application: it is able to download new GPS assistance data and acquire lock quickly. But if you keep this application running while driving, you will see that the GPS lock is lost many times - at least that is my experience.

When using TrackerBooster, not only the "first fix" is current, but all of them. I know that aGps just helps get it quicker, but how do you explain gettings track with 5% error rate to under 1% for the same track using the same software?
I don't know how this program works, but it does and, in the end, the goal is to use the GPS to what our needs are (mine is mostly to keep jogging tracks, with speed and accuracy as high as possible)
As I explained before, so far I can conclude that all my issues are fixed using trackerbooster. It seems like not all users have this kind of result and hardware (or built date) might affect some units, but many of us had good results with the addition of a GPS booster (of some sort).
I actually need gps quite a bit in my line of work. I bought this phone because of it. But, it just does not work. Some claim it works fine, but at the same time they are saying they get 5-10m lock! (thats off by 30ft!) With a borrowed motorola atrix i was getting 4.9 feet accuracy (thats like accurate by 2 steps!). I think I have come to the conslusion that it will never work, and samsuck doesn't even care! Why else would they keep releasing newer phones with the exact same problems? I'm gonna jump ship...everything else about this phone is awesome. Any ideas if HTC has good gps/reception? I am thinking about the incredible S. (and i'm not a troll, I have lived with this phone's gps issues for almost 1 year now).
Get a real GPS receiver, and don't expect it will be cheap if you want a real 4.9ft accuracy.
and for i9000 is about 15ft~30ft accuracy, quite good when compare to my garmin unit.
Samsung should get sued for that piece of hardware ****... but the i9000 is still the best phone
You should try Darkys 10.1 with Darky Core and JVO Modem. GPS works okay but no perfectly !
i do like this:
android market : gps toolbox , in settings has 2 options - download agps satelites and reset gps
1st i download the satelites data
2nd i reset gps
and after closing this app , i open my gps soft and it works , i use iGO
Why do i always hear people with problems my gps works fine since day one. even on the old roms. only with these newer ones i get real fast lock.
never had any problem with navigation software and driving my car
i a using sygic mobile maps because i dont wanna waste data with google maps.
And if your unit performs worse than everyone else's SGS, then you might consider bending the contacts that connect the GPS antenna inside. Seems they don't make good contact on many units.
There is a thread about it somewhere.

Garbled meaning induced by swype when posting from XDA app on SGS I9000.
at the beginning gps was not very good but after android 2.2 and newer fw gps is totally fine for me. outside and in car it works very good. btw data network is activated for me and it helps for faster fix...
I gave up on the Internal GPS after a few Months.
Purchased an External Bluetooth GPS Receiver and now have accuracy to around 5 meters at times.
Also easier as the GPS Receiver can be turned on the get Satellite lock then connected to the Phone.
GPS on JVO ROM is all you can get. It's not enough to lead you driving on a city. GPS antenna is too small, does not update position often enough, keeps using guessing instead of real GPS position (your previous speed is used to calculate the supposed position, something very bad when you're turning around many times).
It's good enough to use it walking outside the city (main reason for me), or in highways (smooth curves and slow change of direction), but the GPS on the Galaxy S is real ****. Worst than the one in my previous two phones, and worst than the one in many current phones.
I really don't understand why having a phone that big we keep having to deal with so much unuseful plastic. 1.5 cm above an below the screen. Just make the phone the same size as the screen. The speaker can go in the top, like in many Motorola models. The battery could be bigger. If they have to make an GPS antenna that's 5 cm long, make it, running along one side.
It's like the phone hanging after a call. I would not advise this device for anyone depending of his phone to receive critical calls at any time. This **** just hangs radomly and you have to force a reboot.
Just to let people know that I've spent all afternoon trying 3 different ROMS, 2 times each, and the GPS sensivity is better on XXJVO.
I flashed the deodexed versions from Ramad, and used GPS status app to test. Just flash the ROM, install GPS status, see how many satellites it detects.
JVJV9 and XXJVP detect 1 or less while on my desk
XXJVO detects 4 and gets a fix, and sometimes it mantains the fix
Next to a window, JVJV9 and XXJVP detect 5 or 6 satellites, get a fix but lose it, most of the time 0 satellites in green.
XXJVO detects 8 satellites, 7 in green all the time
Accounting for the fact that satellite positions change between one test and another, I repeated tests twice.
I tried XXJVP on the field last weekend and was unable to get a fix while on the car.
Phone is sitting now on my desk, and has 4 satellites in green and intermitent fix. Much better than the other ROMs that see 0 or 1 satellites sitting on the same spot.

Gmaps 5.x and above has cache option...I'm finding very useful. Plus offline navigation should be coming this summer
Personally, I've given up on the GPS.. Samsung should honestly be sued, but it is too expensive to do so.
It has gotten better with newer ROM's, but, the sensitivity still appears to be a joke compared to my years old garmin forerunner. It may be good enough for some people who use it for navigation (because, I'd imagine there are plenty of algorithms which can probably be employed). However, the track quality produced seems semi-laughable, and the GPS appears to be nowhere near the quality of a dedicated unit.
People also need to stop checking programs like "gps status". They don't tell you if the location is correct (because it wont show you on the maps). So the accuracy value means nothing (the accuracy value means nothing without RAIM/FDE anyway regardless of unit).
GPS doesn't work at all on my SGS.
I tried that 'push the upper part of the rubberplastic thingy' trick, no result.
Whenever I try to find my location in Google maps, it can only find the WIFI center about 1km away from here. I think that's thanks to the Use Wireless Networks setting. but the GPS in my own SGS has never ever succeeded in locking any satelites.
Must be a hardware fauly I guess?
I bought it in October IIRC.
I don't mind though, never had the need to use GPS.
But it just bothers me that I got a somewhat malfunctioning device.
No big deal though!
Its been working fine on mine.. The only time i had issues was with 2.2/2.2.1

Some data points:
The signal to noise levels reported by the test tools seem reasonable.
All GPS systems use averaging to get a lock.
All GPS systems use Kalman filtering, which filters and connects location and speed, to make the system work at all. The stronger the filter, the more stable the position. But this gives bigger problems in turns.
Dedicated receivers have a much bigger antenna and thus need less averaging to get a stable position.
Receiver software has 'modes' - for example walking and driving mode. In driving mode, movements at low speeds are suppressed.
GPS is still a work in progress; there must be a reason Samsung renamed LBStestMode into AngryGPS!
