I have had GPS receivers previously as well as used some, both normal consumer as well as aviation grade GPS systems. Now I have the Kaiser/TyTN II and I am impressed with how sensitive it is! For not losing signal or dropping position I am amazed, good stuff!
BUT ... since it uses so much battery when the GPS is running, I sometimes turn it of for a while, then on later on again. Especially when moving a lot while being turned off (flying or driving), turning it back on can sometimes give problems getting a new fix! Sometimes it gets a fix quickly, but it is hundreds or thousands of miles off. I know it is complicated 3D math for a GPS to aquire its position, and I know it is possible to get a false lock, but the GPS receivers I have tried and had previously never accepted a bad fix.
The unit knows where the satellites are supposed to be, given the time and approximate position, so that is what it assumes. But when it has been off, and then on again and only moved some hundred miles, it can get this false position fix that it cannot get out of easily. If I turn it off again and wait until none of the previous satellites are in view (flying for another hour for instance), it finally realizes it has to start over with a new fix. Older GPS units I used/had often had an option of making a cold start fix (search the sky, autosearch or other names for basically the same thing). It is also sometimes possible to specify or change the last "known" position of the GPS to make it easier for it to get a new fix again. The latter requires that you either can find your rough position in a map or you know a rough lat/lon position.
So, two questions:
1) How do I break a bad fix, tell the unit it is on a wrong path - do a renewed search the sky?
2) How can I change the "previous GPS position" so the GPS unit is forced to assume another position?
I have some GPS applications where you can change the last know position, but it only seems to stay in the program, it is not fed back into the GPS receiver.
No comments here? Must be others with the same problem. Even the oldest, most basic GPS units had an option to enter position manually, or to enforce a new search from scratch. There must at least be some kind of reset function! (NOT hard reset, thanks!)

I tried google maps and discovered that my actual position was off by some 50 meters from where I actually was. Then I also discovered that in the area I was, if you superimposed the roads on top of the satellite image in Google maps, it was also set off, by about 10 meters only.
Ever since I tried Google maps, my GPS fixes correctly and updates data all the time, but with some programs speed remains 0 and direction remains north even if I move around. After re-flashing the original rom everything is back to normal. Do you know why this happened?
I have got the same problem.
Once after using TrackMe and once after getting my position in Virtual Earth Mobile.
Both times i have used the gps only for a short while and then closed it. On the next start the position has been several hundreds of kilometers off and the speed shows several hundreds kph although I stand still.
Both times the gps has not been ok until the next day.
I have tried to soft reset and also updated the Quick GPS with no result.
I found this thread Kaiser GPS positioning problems which looks a lot like the same.
I have been using the GPS a lot more frequently recently and at first I thought it was these two apps, but now it seem more general. Before I used TomTom on a few occasions with no problem, but then the GPS was on for a longer period.
Anyone else?
i got a question on gps. HOw fast does your tytn ii gps find signal? mine takes forever like 3-4 min? is there a way to increase the signal search? thanks
Which radio are you using?
Mine takes couple of seconds max.

I think it depends upon the radio a lot. Some radios are very quick (I am currently using NIKI XX.17 as I need quick GPS locks - now takes seconds not minutes), others are not.
When I first got my kaiser, T-mobile vario III the GPS was very quick to get a fix taking less than one minute to get the first fix after boot up and subsequently a matter of a few seconds.
Unfortunately this was about the only thing that was quick though, so I installed one of Dutty's ROMs which vastly improved the overall performance of the device for most tasks, except getting a GPS fix which all of a sudden was intolerably slow, sometimes almost impossible.
I experimented flashing various radios but nothing seemed to make much difference so I kind of gave up. The other day I upgraded again, to Dutty's latest ROM and all of a sudden my GPS performance is back to how it was when I first got the kaiser, despite the fact the radio version included in the rom is the same as the one I had before. So I'm very pleased about this, but also perplexed. I don't know what factors influence the speed of getting a GPS fix but for me Dutty's latest ROM is good so maybe you should try that.
One thing that I did notice is that getting a GPS fix was always quicker when travelling in the car not standing still.

Which is strange... Normally GPS's are quicker to fix when stationary rather than moving...
I'll be getting mine soon, so once I have it, I will test with the T-Mobile standard and - if I get it installed, being a WinMob n00b myself that is by no means certain! - with Dutty's latest...

It is strange isn't it? But I'm sure it was true in my case. For example I once walked to work with the GPS switched on as a test, I was holding it in my hand so it had a direct line to the sky at all times. When I got there about fifteen minutes later it still hadn't got a fix. The next day I drove somewhere and after about two minutes it had a fix.
As long as I'm outside (or in the car) under clear sky, I get a lock in Google Maps or Telenav in only a few seconds. Inside my apartment, but near a window, Google Maps will eventually get a lock, but it can take it 3-5 minutes to do so. In my office, which also has a window but which faces out to a courtyard surrounded by brick walls (and up 5 stories above my floor), I just cannot seem to get a fix at all.
Outside with clear sky above though, moving or stable, it is very quick - never more then 10s and usually far less.
What kind of buildings and other obstructions were around you? In order to get enough fixes to pinpoint your location it will often have to see sats out to some pretty steep angles. One guy we met who does commercial GPS systems showed us where the birds were from out on a beach. The 4th one was only something like 20 degrees above the horizon out over the ocean.
Well i have a question.
When i use TomTom or IGO the position on the screen is always about 50 meters off to where I actually am.
So since IGO & TomTom Both have the same behaviour i guess i should look at the GPS module.
My old S730 was always spot on... when i looked at the screen and saw a turn on the left, there actually was a turn to the left.
Anybody knows how this can be solved ?
My TD2 does not have this problem, perhaps there is an issue with your particular phone?
I thoght about it before and found out that it was not inaccuracy but the delay GPS chip needs to calculate your position. Do one test. Some time when you stop at a red light and you know you've waited for about 5 secs, check your position then. I believe it will be accurate then.
I noticed that some GPS's try to calculate your current position based on direction and speed you had few seconds ago. I found out about it one time when I waited at the red light in a long tunnel. Obviously there was no signal there, but when I stopped, GPS kept on showing that I was moving about 40MPH for several seconds before it finally showed lost signal message.
Some GPS's do calculate your position ahead of time and some don't.
Maybe it was because i had assisted GPS turned on...
If you do a search on AGPS LAG (ANY HTCPRODUCT WITH AGPS) then you will see enough posts that speciffically deals with this problem...
My old phone is SPOT ON with TT and my new 2 times faster phone is less accurate, and in a street with lots of turns, take a-lefts etc it's quite important to rely on the machine. And when the machine says turn left on the next corner, is that left the one i am currently at or the one 20 meters ahead from where i am now....
It should be just as with my old phone spot on
Well disabeling AGPS definitely works...
I am now about 20 meters behind all the time. This seems acceptable although I keep finding it strange that my older phone was way more accurate.....
you mean disable QuickGPS or disable AGPS in Advanced Config??
It is definitely a lag issue, not a precision issue: my TD2 internal GPS is at least as accurate as my Qstarz bluetooth GPS logger, and this one has a dedicated large antenna and good GPS chipset. TD2 sensitivity is also comparable, maybe even better inside building, and the time before locking a signal from coldstart is also comparable or better...
BUT there is a lag of maybe 30 m around 50 km/h in my car, and it is is indeed quite noticeable for driving directions...No big deal for me, as I do not rely on voice instruction but always have a quick peak at the screen (I was bitten by ambiguous instruction often enough in the past with other GPS system to have developped this quick peak habit ;-) )..but this lag is indeed anoying...
I'd like to try the TD2 using the external GPS through bluetooth, if I find time to do it this WE I will post my conclusions...

I use to have the same problem as you, so, I've tried the tweak referred in this post http://forum.xda-developers.com/showthread.php?t=514912 and it did the trick for me.
I use iGo8 and NDrive and the accuracy improved a lot, it's almost spot on, no matter what speed I'm driving.
Regards,
I was in my mates Audi TT the other day. He has the built in GPS in the dash board. I noticed there was as much lag as you see on an HTC device.
Also was in a car a few months asgo with someone who had a stand alone TomTom device and that too had lag.
Unless you're paying thousands of Dollars for millitary grade navigation equipment, i wouldn't spare the lag issue another thought.
Not long now ...
There's a bigger lag comming if the media are to be believed (and based on everything that comes from the tele, radio and newspapers these days - there're probably not - they can't even get the weather right)

Diamond1 paid £150 was spot on. No Lag. The speed indicator on tomtom was very accurate, not like on the diamond2 where it takes over 2 seconds to show a speed change. I am surprised that not many people have noticed the slow and inaccurate GPS performance of the D2.
im considering buying this phone,but i hear there's problems with the GPS. my current phone has a great GPS receiver and i use it a lot for day to day navigation.How much will i be disappointed if i were to expect the same from the galaxy s?

Here in holland I have no problems with the GPS reception...
Personally, I found that straight out of the box the gps was dreadful, but an hour later after I did the simple gps fix, it navigated me on a hundred and fifty mile round trip with no problems at all.
The fix is simple and easy and takes literally no skill. When you take your sgs out of the box, see if the gps works for you, then try the fix. If there is still no joy then take it back and say the navigation is busted and you want a different handset.
I'd certainly say its worth trying at least. Chances are can get it working and everything else that you like about droid is better on the galaxy .
It's worth remembering that the gps is not battery friendly and you'll need a potent (2A output)car charger to keep you running on the move.
Sent from my GT-I9000 using XDA App
Basically, in summary:
1) In late firmware, the lock is quite quick, especially compared to car GPS units. Maybe not as fast as some other phones, but fast enough. Certainly faster than my Garmin Forerunner
2) The accuracy boundaries on this phone are wrong sometimes (at least in XXJM5), but this may be a bug in that specific pre-release.
3) With JM5, the unit seems to only lock onto 8 satellites max, but, some people are saying apparently newer firmware's are locking onto more
4) People are complaining of issues getting locks when moving with the unit. However, I've experienced this on ALL GPS units I've owned. AGPS should help with this though (but I've never tested initial lock whilst moving except in a firmware where GPS was 100% broken for me).
5) In some cases, the GPS goes skitzo, this might be fixed in later firmwares
6) Finally, sometimes the track is a bit off to the side, and doesn't handle cornering well.. This is likely related to (2). But this makes it useless for fitness at the moment
Anyway, the GPS is usable, but there are serious accuracy problems with it still. Samsung has said that they are working on optimising GPS for a September update. My best advice is wait until then, because if it isn't fixed in September, the possibility that it is due to poor hardware design seems to grow significantly..
thank you for your valuable input,this forum really is the best on the internet.I'm gunna be buying it next month anyway,so lets see if the update fixes the GPS or not.To be honest,theres no other phone that can match it,so theres no alternative to this phone even if the GPS IS dodgy
The GPS sucks so hard that I'd rather use a regular map for navigation.
My Galaxy S has no gps problems. The first time i went out from house to check GPS accuracy I got GPS signal after 3 seconds. It's stable in 100% cases.
Acquiring signal is not the issue. I don't understand why people keep comparing signal to accuracy. it's not the same thing.
Exactly, there are people in other topics that are just inflating the whole issue, their claims are way exaggerated, and the original issues has already been fixed on newer firmwares, yet they refuse to accept it.

Go for a 20min jog then and show a track of your perfect GPS. I have a lower standard than many of them, but all tracks I saw lost lock excessively at some point or another..
I haven't tried it myself, but can on tuesday.
damn,so many different opinions on this issue.also not being able to track my runs is a BIG minus but still not a deal breaker.day-to-day city navigation is a must though.
It's just as simple as that - you don't check gps functionality just by its fix time. you put it in your car, and start driving - if it's accurate (highly unlikely), gewd. if not - go back here and whine.

The big problem is that many of them seem to be testing quickly from their chair.. There is overwhelming evidence that the GPS doesn't work accurately, but barely any showing it does.. In fact, in one case, I saw someone claim the unit was working perfectly, but the track they showed was on a straight highway, and was fluctuating excessively between both sides of the highway. And the most vocal of those who claims it works perfectly don't seem to be posting logs..
There is also some confusion between whether it is "fitness grade" or "car grade". Car navigation GPS can snap to tracks, and has more room for accuracy errors, because it can assume you always exist on the closest road, and if you use directions, it can assume you took the correct turns when it told you to do so (and correct itself a bit later). That's what most car units seem to do, and it helps compensate for most inaccuracies. It can lead to a bit of pain though if you make lots of turns, some of which aren't correct. Some people are possibly happy because they have used dedicated car units before which suck (some navman's take at least 5 mins to get a basic lock, negating any benefits of having them), but, since some phones offer better directions apparently, people are complaining it should be better.
Fitness grade requires MUCH higher resolution to be usable, because the distance is shorter (generally), and if your GPS veers off course, it gives you a false indication of jogging distance. Garmin forerunners feel generally like they are within 1 or 2 meters a of the time (but occasionally veers off 3), but from what I've observed standing still, the flaws may be less visible when moving, but simply appear as slightly off course.
Then there are those people who stare at the SNR/locked satelites for hours at end without checking whether the long/lat is actually correct, or the accuracy boundary (they see 5m accuracy, but don't actually check if it is accurate within 5 meters). I was one of these, until I realised that the accuracy boundary was wrong..
Part of the issue also comes down to firmware though. People are using pre-release/leaked firmware (which might not even be complete) and are judging the GPS quality based on that. No comment needed except, don't assume that Samsung aren't working on fixes because there is no fix in pre-release firmware.
I haven't properly tested either though personally because I use a forerunner for jogging (waterproof), and since I fly, I prefer to use maps to understand locations better. I did notice though that leaving my phone on my desk for a long period of time sometimes allowed the signal accuracy boundary to not include me (ie, allow a position of 20m away from me, but show 5m accuracy) intermittently. And this might explain the fluctuations in position many others have gotten..
Either way, it is debatable. The biggest issue is that the assumption so far is that everyone got exactly the same hardware, and exactly the same revisions. But the other problem, is that GPS quality is open to opinion, because in some areas, roads are so far spread out that even inaccurate GPS works fine for driving. It really depends on your needs. But the facts are, the accuracy of the GPS isn't worth debating anyway currently, because Samsung have already told us they are "optimising" the GPS in Sept, which may make this unit as good as a garmin forerunner anyway. All any of us can tell you as that we'll know the TRUE potential of the unit after the september patch.
But for me anyway, I think the GPS is fine (I don't need perfect accuracy, even if I needed this as a fallback in a plane)
The GPS is bad to the point of being unusable for car navigation or fitness tracking. Yes you may get a lock in GGps test but when moving the reported location is all ov
er the place.

Case in point to illustrate what andrewluecke is trying to explain here about the accuracy not being exactly...well, accurate. Take a look at the attached screenshot. My GPS had a great fix with accuracy of 5m (the best it's able to report), stable for a few minutes, everything was working perfectly. Or so it seems. Except for the slight problem that I was actually standing where the red dot is... There's no scale on the screenshot, but it's a good 30-40 meters off. And that's quite common for me.

Exactly Case_. The point of the accuracy measurement is to say "you are somewhere within this range". But, with the Galaxy S, it isn't, and that shouldn't happen, at least not as often as it does (except maybe at the beginning whilst obtaining a lock"). Professional systems have something known as RAIM and FDE which detect when the accuracy may be incorrect due to external factors (such as shonky satelite, or serious atmospheric interference). But this happens a LOT, and I would have thought it affects GPS units equally (unless the Garmin forerunners in fact DO ship with fault detection, which could explain it, in which case, Samsung should implement fault detection and exclusion too, to make it usable).
Anyway.. What I am trying to say is summed up easiest with Case's post.

It most certainly is an issue. It takes a minute or longer to acquire a lock in some cases despite stationary and clear line of sight.
The people who stomp their feet with "The GPS is fine" are no different than the iPhone4 users who claim there is no attenuation in their phones.
In my case with the DDJG4 update, I see some minor issues.
Once in a while when I am at home (indoors with no visible satelites) my location shifts from bangalore to toronto. All my stuff changes to that. It looks like AGPS is not turned on or buggy becuase 80% of the times it works well. Does anybody else face the same problem ?
So when my phone takes me to toronto, i restart the phone and everythng is back to normal
SOmetimes, the location service fails to find where I am and shows Toronto in Google website. Is there anyway to avoid this.
It's just like what most people say, you can get a fix, and GPS seems fine. Try to use it, and it's a whole different story.
Somebody on the forum posted a link of a run, where the SGS GPS went everywere but on the straight line, it even made a hilarious loop. Too bad i can't find it.
People need to stop saying "Firmware updates fixed it already" as that's just not true.
Hah, there it is, posted by sjdean.

I have had continuous issues with the Droid 3. One of my biggest issues is that the GPS seems completely unstable. I have tried turning on/off GPS options, etc...
Weather I try to use Google Maps or another application such as Endomondo, it cant maintain a lock. It seems to be able to locate me within 12 - 30 feet and then within a mile!!!
Using an application like Endomondo (running, cycling, etc), is completely useless. It can't track my location at all and when it does lock on, it only holds for a few seconds and then gone again.
I took the phone in to Verizon with a complaint about the GPs and screen issues (http://forum.xda-developers.com/showthread.php?t=1239980) and the rep said both were normal for this phone...
Has anyone figured out a way to resolve this problem?
I, too, have the same issue with GPS. I use SportyPal Pro, and cannot use my Droid 3 when running/walking. I can go for a 5 mile run, and SportyPal will show I had ran 6 miles. I can run north to south in a straight line, and when finished, SportyPal will show that I went east and west as much as 400-500 feet off of that straight line and because of that can add anywhere from .1 miles to .5 miles to that 1 mile run.
It is so unreliable that I will use my older decommisioned Droid2 to run with. It works perfectly with the same software.
If anybody has any suggestions, I'm all ears.

Are you using it for navigation only? Or a similar application for running/walking?
The reason I ask is because I do not notice a problem during navigation. It works great for that without any problems. Until I get to downtown Chicago. I almost expect problems there. Even with my Droid2.
i've only had issues with my gps in areas with lte. when im at college im in a city with lte support and my gps doesn't work (my friend who has an X also has issues with his gps when in areas with lte). when im home where there isnt lte support my gps works fine.
No it's not hardware mine works flawlessly and almost instantly fixes position, tho i have modded the gps.conf found in the etc folder. Details for tweaking this for your region can be found here:

Many thanx to 75markus for this.
Since we don't have a recovery yet to flash a zip you will need to edit the gps.conf file manually.

The problem I was having with the GPS from Day 1 is that I would occasionally notice that it would not start up at all when openning a GPS-dependant app (such as Maps or Weatherbug, etc). Whenever that happened, I would have to restart the phone, and then the GPS would be able to initialize again... at least, for a while.
Eventually, I was digging around in the setting and found the "VZW location services" option under "Location & security settings". I unchecked that option and, ever since, I've had no problem with the GPS. It seems that th VZW-based location services were causing the problem. Of course, since then, I've rooted and frozen all of the VZW bloat, so I might be able to turn that option back on with no ill effect. Still, it was as simple enough fix.
My issue might not sound exactly the same as yours, but you could give this a try and see if it helps.

I have been experiencing the exact same problem and temporary solution (restarting) since day 1, on both my first and second droid 3's. Difference is, I've had VZW location services unchecked since around the time I first got the phones, and I am still experiencing the problem... even as recently as last night. I just double-checked the setting, and indeed, VZW location services is stil unchecked.
Once I have lock I usually have no problem continuously using GPS. Last night, I tracked a two and a half hour walk using the My Tracks app, including a 45 minute stop for dinner indoors. For the first 10 minutes, it couldnt find a signal, so I restarted. It got a lock almost instantly following the restart and never lost it after that. I had the app running for the whole excursion. As expected, it got a little confused while I was inside, but automatically picked the signal right back up when I got back outside and tracked my entire walk back home.

When you look at your walk on the map, is it true to where you actually walked? If I do that same walk on my phone, it will show me deviating off course as much as a 1/2 block and then back. I can tolerate that deviation once and maybe twice during my runs/walks. However, mine does it the majority of the time, adding bogus mileage to my walks/runs.

When you look at your walk on the map, is it true to where you actually walked? If I do that same walk on my phone, it will show me deviating off course as much as a 1/2 block and then back. I can tolerate that deviation once and maybe twice during my runs/walks. However, mine does it the majority of the time, adding bogus mileage to my walks/runs. In an hour's time, it will deviate approximately 20-30 times.

Just took a closer look at the track it recorded. I definitely do see these kinds of deviations, but they seem to only be in areas where I think it'd be reasonable to expect them. I live in a suburb, so I don't have any tall building to mess with the GPS reception, instead, I have somewhat steep hillsides. It seems I get a fair amount of deviation in the (significantly) hilly areas (it looks like I was walking down people's driveways, then across their front yards, when in reality I was just walking more or less straight down the sidewalk), but in the flat areas the line has almost no significant deviations, just some minor noise. Next time, at the risk of my fiance calling me a geek, I'll take my Droid 1 along for the trip, and see how the two records compare.

I've attached screenshots from two runs. D2 is this morning's run with my Droid 2. It's flawless. D3 is the last run I did with my Droid 3. Looking at it you can understand my disgust with it. Ignore the big missing section from both shots. I wouldn't want anyone knowing the exact location of where I live. Someone might come steal my Droid 3.

WOW... That is awful but a great example of the concern with this phone. You are actually doing much better than me. Mine is only able to triangulate down to about 20 feet and then it bounces between 20 and 300 feet!!!
I am going to call VZW today and see about a replacement phone but I doubt it will resolve the problem.
I just called VZW and once again, they said the accuracy was normal... They said none of their phones can lock on with the accuracy I described and if it has, I have been lucky. He said their phones are only accurate within 500 feet!
I explained to him that with that accuracy, it would be totally useless to use as a navigation device...
He looked through their documentation and said he has no record of other people having issues with the GPS... He also said he has no record of the blue tint when taking pictures.....
Oh well. I hope the replacement fixes it...

With that kind of change in accuracy, it seems like it isn't using the GPS as all, but just the cell towers. Is the GPS logo showing in the notification bar when that is happening? If it's there, is it blinking or solid?

My humble opinion of VZW representatives...they're all full of BS. They're going to tell you what they need to tell you to get your out of the store or off of the phone if you're not buying anything. A representative's main concern is sales. Sell him another phone, renew his contract, add a line, add a feature.
This issue may be better addressed to Motorola directly. I may make that phone call today.
I just got off the phone with Motorola tech support. Same story as VZW gives. There are NO known issues with the Droid 3. I asked about the GPS, the bluish pics the cam takes and battery life. The only thing the tech would say is the phone "needs to be evaluated"
