This bluetooth gps receiver (canmore GT-750FL) is simple to use and satellite reception was always great, even during snowstorms, being indoors, or metro areas. In six months, I never experienced anything that disappointed me w/ it's performance with my Dell Axim X51. and Hermes.
Absolutely has exceeded my expectations right out of the box, so far. I should probably wait until I've really played around with this device a bit more but so far it's amazing. I test it up with my BlackBerry,x51 and hermes and right away it was on the ball. Using the Google Maps with it, it said it had located my position within 20 meters. I switched over to the satellite view in Google and zoomed in on my current location. Baloney! It was more like 20 inches! It showed my position to be not only in the correct parking lot but the exact parking space I was in!
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.)
Hi All,
At the moment i own a TP (a.k.a HTC Raphael), but i'm thinking about buying a new phone and the HD2 is one of the candidates. Before buying i would like to know if the GPS performance of the HD2 is up to scratch?
For some unknown reason reviews never (...hardly) include GPS tests.....WHY!!!??
The GPS performance of the TP even with the official HTC patches is still worthless. Waiting for a fix could take an hour (i'm NOT exaggerating).

i know what you are talking about, i had an TP before my HD2 too, and i have to say there is world of difference between them. with my tp i had to wait about 15 mins. with hd2 about 10 seconds.. even inside buildings i get a fix! with my tp i wouldnt even hoped for that.
so yeah its a LOT better
The HD2 is in a different GPS league from the TP, Diamond, etc. They were a disaster.
IOW it's much better IMO.
Works pretty good. I just enable QuickGPS when I flash a ROM and I never have any issues (never tried using GPS without that!)
I've an everage GPS fix in ~15sec.... It's brilliant! even from cold start!
Sometimes you get GPS even in very light buildings
GPS is awesome, simply awesome... outside get a fix in a few seconds with full sat coverage (all the columns show a satellite) inside it takes a few seconds longer and again full columns... there is barely any lag on the journy (icon vs real travel)...
GPS fix in 30 secs in Street Navi, 15 secs in Aviation software ...... great!
Also, 10-15 seconds, outside even less...
What I find amazing: Even in my living room, sitting about 1,5m away from the window, I get fix to 7-10 satellites within 20 seconds...
(Always with fresh QuickGPS data)
when i had a diamond i had no issues at all, the hd2 is a lot faster
I have never used GPS on a PDA before but have a dedicated (new) TomTom GPS unit and when I decided to try my HD2 I mounted them both in the car and ran tests.
Within 5 minutes my mind was made up. The TomTom was outperformed in all areas. The route recalculation is much much MUCH faster than the TomTom and the same applies for the aquisition of the GPS signal. Combine this with an awesome screen and it is perfect. I play music throught the headphone socket to my car stereo and run GPS at the same time. When a call comes in the music mutes and resumes when I hang up. The GPS unit runs in the background without any issue. The TomTom GPS unit is now in the cupboard collecting dust.
I have never used quick GPS as I have never had a need.
I agree, HD2 GPS works like a charm.
QuickGPS - what for!?
After reading the feedback in this thread, I suddenly remembered the QuickGPS. Last time I used it was two months ago, because... it was there to be used! Without QuickGPS I get a fix in my HD2 in around 5 seconds! I am not joking! Never felt the need to go for QuickGPS. BTW, went just now to Options and ticked "Download QuickGPS automatically". Why not!? I have Copilot 8 and love it. Just missing the QWERTY keyboard. Otherwise, there's no better combination in the world when it comes to portable phone-music-GPS-video-Internet-camera-etc, etc.
Wow! Thnx u guys for the feedback!
I can live with getting a fix within 30 sec's on a cold start (coming from an avrg. 15 mins for a fix). The HD2 seems to be the PDA/Phone that i have been waiting for since the dawn of Pocket PC 2002 .
HD2 here i come!
I've found the HD2 to actually get a GPS signal even inside my dad's car. no other gps device can get a signal through the windscreen. It's weak on the HD2, but there!!!
A bluetooth GPS stick cannot even penetrate it.
HD2 GPS is a joke!
I do not mind much if the GPS locks indoor, though HD2 does it very easily indeed (and fast). I find really bad is the very poor precision of HD2 GPS - it constantly gives a 20-40 meters error in all directions (no matter in the city or in open field, no matter how many sats are found, even 10). My old Samsung i780 has an error within 2 meters. Just record your path (on feet) with e.g. RunGPS or NaviComputer and you will see the the ugly zigzag line instead of a smooth one which I used to have with i780. Of course if you are not lucky to have HD2 with much better GPS than my..
(It is almost OK with TomTom car navigation, though, with occasional map rotating and recalculating the route).
GPS is very fast and precise here, definitely the best GPS signal out of all the WM phones I've owned
My GPS with iGO conects in about 10sec and its very precision. Corect in area of 3-4 meters

This is interesting, maybe your old Tmous radio (..50..) is doing a miracle. i have 2.09.51.03 radio, the previos 2.07.51 had the same bad GPS precision.
However, how do you know that it is precise? If I simply looking at a Google map standing still, I see pretty precise spot which my GPS gives, but once I begin to move, the position begis to jump 20-40 meters to all directions..
HD2's GPS really rocks! My old N95 took about 15 mins to fix.
yep fast here as well about 10 sec for a fix cold.
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!
Recently my GPS lock is epicly slow on google maps.
In fact, using GPS Test is the same as well
Previously I could get a lock using GPS Test within seconds
Nowadays it takes about 5 minutes
The same with me mate, I
use gps status to reset the agps data & it works sometimes
Sent from my GT-I9100 using Tapatalk
Same here!
In fact I just wanted to start a new thread.
It takes like forever to lock, but when it does, the accuracy is awesome and never loses the lock. Tracked almost 100km with it and all the track was on the road and no ghost walking or whatsoever!
Will give GPS Status a test and report back
For me it's quite the contrary :
I have a fairly quick fix, but the accuracy is never perfect (circle around my position in gmaps, ang gps status measures 15m of error most of the time).
Dispite this lack of accuracy detected by my S2, my position seems always correct when using gmaps.
I would agree about the accurate fix part
Once it locks, it stays locked and accurate, no jumpy jumpy stuff
Just wondering if there is something wrong with the Google maps software or the eyes in the sky... cuz this unable-to-gps-lock thingie just surfaced last week. That's why I got GPS Test. Initially GPS Test was able to lock fairly quickly, but this week, it slowed down alot!
Strange, that!
Which modem are you guys using?
I checked mine and it locked on my location in seconds with reported accuracy of 10m
I'm on KE7 modem right now. Seems to work for me better than others.
Used KG1 and sucked for me. Never got an accurate lock (specially when I'm on the move).
I'm trying to switch to ZS*** modems because Hong Kong modems were way better on my SGS. Wonder if it's the case with SGS II..
I have had an unusual effect when navigating. It loads up the route and says 'searching for GPS' However it does find the GPS signal because you can see it tracking but it doesn't switch to the 'in car' view and still says it id searching for GPS. It is as if the GPS chip is unable to tell the phone it has locked.
