Hi i have weird problem with my GPS.
While I driving (car is moving) everything is beauty and sweet but once I stop my car my GPS is still moving for about 10 sometimes 20 sec showing 2km/h then 0km/h then 2km/h again. Sometimes when I stop car on junction my Gps will jump on the perpendicular road and from time to time my arrow on the map just turn around to opposite direction and the maps sets a new route! Once i move my car everything going back to normal.
I was using first my TomTom and i just thought it`s a map problem although i haven`t problem with that on my Rhodium either X1. So I decided to try Igo8 and it`s exactly this same. Even on the roundabout my gps can jump somewhere else on different road.
I tried all Radios available for HD2, many Roms and just have no idea what more I can do. Many people on HD2 forum in Poland have this same problem.
I also tried GPS fix cab downloaded here from xda but no luck its ever worst.
I can add that i'm getting GPS fix in few second so its good the problem is just my gps is moving around.
PS. Very, very rarely have no problem with this jumpin gps around. But is like 1/30.
Do you have access to an external Bluetooth GPS receiver you can test out? That could eliminate or isolate some possibilities.

unfortunately i don`t. but on my Touch Pro 2 and Xperia never had this problem.
hi,
are you using the 'gpsmoddriver' software, that is floating around here in the forum?. its made for using the compass data when no gps fix is available. it causes such failures in igo and copilot on my hd2. after uninstalling it gps works much more percise to me, when im not moving.
regards mad
Happens with mine as well. I have replaced my HD2 and it seems that the 2nd unit acts the same. tried various ROMs/RADIOs (official/cooked) - nothing seemed to fix this.
It's quite funny though... most of the people rather paying attention to the fix time instead of the accuracy (which is quite bad imo) in addition to this weird phenomenon. I doubt that the AGPS is somehow related, but it will be nice to know how to disable this feature, and try to acquire the signal without it. maybe this is the cause.

Agps - this feature is available in NRGZ roms. I tried to turn on and off and it was no different.
PS. thanks for answering.

As i said before : i was using it. I had feelings its jumping around the places more than without it so I uninstalled it.
Tried to email HTC regarding this. they claim that their HD2's don't exhibit this behavior, even though I've tried two different units, from different batches.
I don't know what to do... this drives IGO nuts - it causes igo to switch lanes, directions and having the route recalculated without any good reason.

Sometimes its just pointless to talk with those dickheads.
They ll never say true.
With pink camera was this same. They were saying at the beginning that they have no problem with pink spot at all. And what was next? We need just more people to email or ring them.
Most of them even not using HD2. They've seen for few minutes and think they'll know everything about it.
It was so many bugs with this device they just dont want to hear about another one!
In addition to that, both of my units tended to show different position and altitude readings each time i powered up igo or google maps. while exhibiting the differences I obviously didn't from my current position, not even an inch.
to try to make things clearer. that's what I did :
loading igo -> acquiring signal within seconds -> getting a certain position reading with altitude of 11 meters (for example) -> quit -> reloading igo -> acquiring signal within seconds -> slightly different position, altitude of 75 meters or a negative value (for example).
even the small blinking dot in igo (which determines the actual gps mark) doesn't fit to my physical location on the road which I'm currently driving on. it sometimes blinks few meters to the right/left, and sometimes it tracks behind the guidance arrow (as it should be).
Could be
Simply a limitation of GPS. I have seen it on other GPS's. Garmin etrex. Try walking with one and even thou you are walking in a straight line it plots a zigzag path. More satelites (10+) should reduce this issue.
Basically the GPS is only accurate to a certain range from +-50m to +- 2 meters depending on the no of sats. The location is detemined by timing from when the signal was sent to when it was received. Calcs how far away the sat is (Speed of light??). It is possible you care getting a fluctuation in your current location. Eg
Sample 1 says you are point a.
Sample 2 says you are 2 meters to the right.
Sample 3 says you are 2 meters to the left.
Still in the +- 5 meters but the gps is plotting you moving backwards and forwards.
Guys, it is a problem everyone has, gps position is not as accurate or stable on the hd2 as on most other htc devices. And with an erratic gps position automatically comes an erratic speed. Don't know yet if it is because of a different gps module that's inside the hd2 or because of the inclusion of crappy gps drivers. Will try to find out soon....
Anyway, gpsmoddriver is not the cause of this problem since the problem is also on an hd2 without having gpsmoddriver installed. Because of the functionality of gpsmoddriver to improve the gps readings, in some cases it can amplify your erratic gps position, and that is also what some of you have been experiencing. Remember you can always use gpsmoddriver to add the hardware compass functionality to your navigation software, while additionally configuring gpsmoddriver to leave gps data untouched so it won't make the erratic position and speed worse. For more info or help, please visit the gpsmoddriver thread: http://forum.xda-developers.com/showthread.php?t=571266
EDIT: Of course the HD2 has a new snapdragon chip which has built-in GPS just like many previous generations of phones. Most likely qualcomm changed the way gps works in their new line of Snapdragon processors...
The movement of vehicles around you or even the movement of the sun's rays on buildings nearby can distort GPS signals. The GPS navigator software tries to rationalize this distortion and that usually appears as a movement when you are still. On the other hand, if you drive into a tunnel using TomTom and some other software, you will often see yourself driving straight on in the tunnel well after the GPS is receiving no more satellite signals.
In top-of-the-line built-in navigation systems, the GPS data is supplemented by inertial guidance. (Someone could create a similar supplement for the HD2 The supplementary information allows the system to reconcile the GPS information with information on your car's actual movement.
But for us mere mortals, we just have to live with it.
Well... this particular gps chip is quite useless, then. if my navigation program has to recalculate the route each time I stop at traffic light, then it seems that I either have to purchase a usb-based gps to pair with the HD2, or replace this device. I counted on it to perform well.

Complain to HTC, perhaps if they get enough complains they will come out with a hotfix or a rom upgrade that fixes it. Nobody said that the hardware is not that good (though it's possible), but it could also very well be a bad implementation by HTC!!
Already did.
They have obviously denied my complaints.
thanks again, anyway.
I noticed this behaviour yesterday night, at about 10pm. I was playing with NoniGPSplot, and while I was completely still (and freezing me arse outside believe me), it was tracking a movement back and fro and all around in small step, keeping track of me traveling some meters still while I was standing in the same point.
It was night and I was in my big yard, so no sunrays nor moving vehicles around nor buildings over my head.
I think this behaviour is very well hidden in tomtom since it automatically puts you on a road, and "smoothens" the gps data by making you follow that road no matter what, but a "realtime" software like nonigps tracks that all so well. Gonna notify htc about it now.
Guys, let's not go overboard on this. Non-military GPS is only claimed accurate to around 20 metres, regardless of the quality of the receiver. It's the US Defense Department messing with your HD2, not HTC.

Yes, absolutely, I've noticed the same behaviour with all three of the BlueTooth GPS I used in the past. So, I would not be too quick to blame HTC for this.
my touch cruise's gps receiver worked with static navigation enabled to avoid this false movement. maybe this is just a usual behaviour?
Agree to that.
But regardless of the fact that the thing is not a military GPS system, It should do it's work correctly as for me the GPS is almost useless when driving slow or within a city. My 2nd phone (HTC DIAMOND) and 3 personal navigation devices are mounted in my car to compare and all work fine when the HD2 isn’t .
The GPS looses all the time the fix to the satellites and then quickly gets the fix back. when using a GPS monitor you can see that the satellites constantly moving really rapidly. (moving --> getting fix and loosing it again)
This is for 4 other reference devices which are running simultaneously not the case so it seems really an issue with the GPS device.
I tested this with different ROMs (1.44 Vodafone, 0.6 dutty WM 6.5.5, 1.66 stock and another one I cannot recall the producer anymore.)

I bought the HTC Touch HD a few weeks ago and noticed that the accuracy is not just bad, but atrocious. It can't even locate me within a 300 meter radius. Is that normal? Does anyone else have this problem? I am using the latest Google Maps.
Thanks in advanced.
I would try a proper GPS program and see if it is the same, if so your HD is faulty.
No problem here. .Maybe silly question, but did you click on "Use GPS"?

Are you sure you have a satalite lock? Google maps also determines position from cell towers and gives an estimate to your location within approx 500M. Once gps is activated and satlites have been aquired, a more accurate position is displayed (and i get a blue triange above the location - i guess to indicate actual position).
The little blue trianlge shows the direction you're moving - so the GPS is pretty accurate! Sometimes it doesn't get a lock for a while (it'll say at the top-right when it has active satellites) - if not, then it just uses that cell tower triangulation thing which gets it within about 500m as mentioned above.

Ya, it is on.
It can get working when I'm on the move, but as soon as I am still, it screws up. For instance, I can be driving to work and it works fine as far as telling me where I am at the moment. As soon as I close it and reopen it at work, it tells me I am somewhere 300-500 meters from work.
I guess I don't understand how it can work so well on the move, but as soon as I need an accurate reading, it is way off. Does this happen to anyone else?

Once it's closed it loses the "Use GPS" setting and you have to turn that back on and wait for the Satellites to be located all over again.
Well i think there is a gps delay issue with the latest HTC phones as blackstone, Raphael and diamond and i believe there is a little on the x1. Well there will is always ways to tweak settings in the registry i guess. well you'll probably find something here at xda...
Ok, I see what you are saying...sa we speak, I am trying to get the location of where I am at on my phone. The status has been on "Seeking GPS satellites (0)" for about 3 minutes now. It just relocated my location nowhere near me.
Ok, I just got a message telling me that my "GPS receiver is having trouble tracking GPS satellites." It's a very clear night in southern California, no clouds, no trees, etc...If it is because I can't get a satellite, is there a way to configure it?
Can it be because I am inside my house? If so, that is absurd!

Well i suggest you to go out and test it.. well also i suggest you to always keep your quick gps application updated so you'll get a quick fix locked to sattelites.. my Raphael locks on around 20-30 seconds and sometimes even less....
no problem here!
i've tested head to head with my old Asus P535 SirfIII (wich is pretty good as gps) on a 300km trip and they react in the same way.
no lag, no errors.
i use iGO8!
Well i found this on youtube: omnia vs HD in gps...
i am aware of that greek clip
what can i say? they have their experience, i have mine.
from my experience i say the gps of hd is good enough, as long as i don't make maps and i don't need precision on cm level
GPS works great on HD. Tested with IGO8 and latest TomTom, as well as Google Maps - all have accuracy within 5m range, wich is more then enough for normal navigation use.
I also tested my HD along side with Garmin car navigation unit - they were literary synchronized to the very second, even the voice instructions came at the same time, it was actually very funny
If you're having problems, I suggest you look up here on the forum for HTC GPS tool.
Well just to say, I agree with you guys eventhough i have a Raphael.. well i guess the gps chipset are the same.. (correct me if im wrong though) .. well many people in the Raphael community is talking about 50 - 100 yards lag but i only experience 5m, the most ive experienced was 10m but that was just once..
GPS doesn't work inside. Not just on the Touch HD but on any GPS device.
At the most, my lag is a car's length. I think my Trinity was slightly more accurated but not by much.
As far as getting a lock from inside, I can occaisionally get a lock if I am sat by my West facing window, but otherwise not a chance!
Ok, I got it working! I guess it just takes a couple minutes without touching any keys to acquire the satellites.
So in conclusion, to impatient people like me, don't touch any keys for a good minute or two. Thanks, guys!

Mine does. Can take about a minute/minute and a half to lock to the satalites, usually finds about 9 of them, and from google maps when zoomed in to max you can see roughly where abouts in the house the handset is.
The cell tower lock is useless. I'm in the north west of england. The cell lock feature keeps telling me I'm in Russia!!
like all gps i have used, sometimes getting a fix is hard work, regardless of apparent sky conditions.... i guess thats what happens when technology (the gps sats) are made by the lowest bidder
if you have a "your postion within 300-500m" message displayed, then that is using the cell mast to get your position, you never see this message when using GPS
some progs and some roms prefer to have the gps ports mapped, i do it manually for all my gps progs using com4 and bit rate of 9600k... seems to offer best situation
afaik, no civilian GPS can assure an accuracy of greater then 15m, although some units some of the time seem to be more precise
i dont see lag, i see the limitations of GPS (outside of military application... but then again, we've seen how accurate smart bombs are not!!)
Few people are complaining now about the low quality of gps. Can you prove this?

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.

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.
Well here I am near the river Thames near where it becomes tidal - ergo, pretty close to sea level (actually about 30ft above). My new all dancing DHD' GPS system tells me I am 230ft in the air. I honestly do not think I am that high!
It seems to me the DHD contains a blast form HTC's past, the Touch Cruise also added 200ft to the GPS heights. Why have they implemented a GPS hardware issue they have known about for years...is the GPS system hardwired into the snapdragon chip? Is it the kind of thing a software update will eventually correct?
I use OS maps a lot for hiking and tracking, and while I know the height issue is not a big thing as I know the problem, my tracks will always be out by 200 ft vertically.
However, the compass works, unlike on my old HD2...but I really hate little faults like this, they gnaw on me...I really hope none of the GPS system implanted in the noses of bombs and missiles don't have this fault!!!
This may be the app you are using.
I use Compass from Catch.com and find it pretty good.
Also make sure you are receiving signal from at least four satellites to get accurate reading.
my bad
thanks for the advice - MM Tracker is clearly out buy 150-200 feet in altitude...I have the compass as well, it has accuracy +/- but I can't see where it has altitude.
Open Compass app.
Tap 'Menu' button, then Compass Type then GPS
On large Green Bar it reads Speed, Altitude and Accuracy.
Bottom green display shows how many satellites are in use.
thanks, I had not seen that feature, very nifty - when it has stopped raining I will go outside and full complement of satellites and check. Certainly held up against the window, the 200ft discrepancy does still seem to be there using the compass...I will check later – thanks for your thoughts on this.
nope there is a problem
according to the compass I am 316 foot in the air. I beleive where I am is about 25 foot above sealevel - looks to me that HTC has reimplented the same fault they has on the Touch Cruise. No biggy, but it is annoying, a little
If you look through this forum, a few other people seem to have a faulty gps .
My suggestion would be, get in touch with who supplied the phone for an replacement, as a wrong reading on GPS will affect footprints, locations, sat nav etc.
Maybe you do not use these programs much, but with the cost of the phone, everything on it should work, especially the hardware.
So I hooked up my bluetooth GPS to the phone the other day, and one thing I have noticed (during testing driving only, with MyTracks) was that the track was indeed better, however all the while the compass arrow was swinging wildly from one direction to another. Sometimes 180 degrees while phone and gps were sitting still.
This leads me to wonder if the GPS itself isn't the issue, but some integration with the other sensors. Has this been discussed and considered?
(I know someone mentioned it recently, which is why I paid so much attention to have noticed the way the arrow was deviating from the direction of travel.
No, the GPS is defiately the issue.
I had seriously thought this for a while and suspected some sort of sensor mixing on Samsungs part, but now that i've investigated the phone thoroughly, including roothing and looking at the drivers and processes that run while navigating I can confidently state that the teeny-tiny GPS antenna is the problem. That and a proliforation of advice in this forum to use the GPS in MS-Assisted mode, which doesn't use 'GPS' at all, but mobile base stations instead.
The reason the compass was swinging around was probably because you were driving in a car made of metal.
I saw very similar behaviour when I first got the phone and had it in a case with a magnetic fastening. Strangely enough no matter what direction I faced I was always heading south according to the phone.
You can help the phone out considerably however by making sure that it has a decent sky-view in a car - so put it in the windscreen rather then attaching to air vents.

You could try using the 'calibrate' option of the Compass program (catch.com) that is available on the Market. It gets you to do a figure 8 movement of the device during the processes. I have to do this after using my beltclip with the magnetic fastener which messes up the compass. I think it's best done outside the car. Before I did that I was always facing south too!
As far as the OP's post, I don't know if the calibration would help when an external GPS unit is employed.

first of all: the gps implementation on this device is a disgrace. absolutely worthless. as far as compass goes, that is a weird one. you can get it to work sometimes by running /system/bin/sensorcalibutil_yamaha (need to be root to run it). but it "breaks" again after a while.
also if someone could test the following: get wifi signal, get gps position (not a-gps, turn that off completely), be sure that the lock is there. then switch off the wifi without touching gps settings. does the gps lose signal instantly after switching off wifi?
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!
