I've got problems with the GPS on my Polaris and I'm wondering if anyone else has the same issue: the accuracy is abt 5-15m off and it updates less than 1frame/sec regardless of the gps software I use (tomtom, google maps or garmin xt) My Radio version is 1.64.08.21 Murata and the rom pdaviet v16
Can anyone point me towards a solution for this please? Thanks!
To my knowledge gps is off target for a reason. All comercial versions are innacurate either in time or position so you cannot use it for war or something like it. If the 5 to 15 meter difference is to much I do not know.

Thanks for your answer pereirald, I knew that commercial GPSs are off so they can't be used for military purposes but the GPS on my Polaris is annoyingly slow. If I compare Garmin mobile XT runnin on my polaris with a friend's Garmin nuvi 760, his is smoother, updates faster and slightly more accurate...so any1 knows whats going on here? Is it only me with this issue or it happens on all HTC phones with Qualcomm chips?
I am on the latest udK rom using radio 1.64.08.21
I can GPS sync inside buildings
Syncs VERY fast
I also find it very accurate and def not 15meters off
Actually I also use Garmin XT and most of the time I can even pinpoint me using "Where am I?" but sometimes it does not give the right door but the neighbours. So I guess there is an up to 5 meter innacuracy. Being slower one should expect: The the chip isnot dedicated is it? It does other stuff while we are trying to use GPS. So you could try to things:
1) Minimal services running and disconnect phone (Airplane mode)
2) I don't know but that is a possibility that you will get different results with different rom. (I think I do, altough I haven't measured it).
Hope it helps

The accuracy depends on the number of satelites as well.
I noticed that the GPS chip of the TC is more nervous then a SirfIII chip like the one I had in my MIO A201.
But both the MIO A201 and the TC didn't show a better accuracy then around 10M.
Thanks for your replies guys, I did some testing over the last 2 days and after taking a trip in the middle of the country with the GPS on, I was surprised to see that it fixed itself At home is not showing me 5 doors down the road and in someone's garden anymore and when I walk/run with it, it pinpoints my location within 5m. The smoothness is still not there even if I turn off the music player and any other progs that I had running in the background, but I know thats because of the lack of proper graphic drivers
So in conclusion the accuracy is down to these 3 things:
1.radio flash not os-rom update.
2.number of satellites it connects to.
3.apparently driving around a bit
Cheers!
In case you use google earth, its the program which doesnt update quickly enough. The receiver does...
The receiver has a very irritating 'feature' built in which is very annoying when trying to use your GPS unit while walking: to make car navigation less jerky and stop you from jumping from road to road, the receiver doesnt update the position anymore after you came to a stop (or move slowly, eg: by foot ). It updates again after you covered several meters of ground and keep moving. This might be useful in your car where you can move fast and steadily, it's very very annoying if you try to find something by foot. The 'feature' is hardware-based, by now no one managed to turn it off.
Edit: uuhm... yes, of course the Radio. The Operating System part of the ROM only houses programs and such, the hardware-near stuff like phone functions, bluetooth and wifi and most important the GPS stuff gets updates through the Radio-ROM. I figured this is a widely known fact...
Do somebody know if there is any difference (in practical terms) in GPS implementation in both devices.
I've heard (unconfirmed) that Xperia could not use its GPS module without access to gsm network (it is capable only of aGPS) while Touch Pro could do both (aGPS as well as stand alone GPS).
Please let us know.
Thanx.
I haven't tested neither of them so I can't tell you about that, but what I can say is that the rumour you´ve heard (about only accessed to gsm network) is NOT true. aGPS is just like an ordinary GPS but with the assistance of the "a" (the gsm network) when and if available.
GPS
It makes sense. Thank you.
The Xperia has both network assisted gps and regular gps
the gps is in the qualcomm cpu same brand on both devices as i'm not wrong
Since both Pro and X1 use the same chipset for GPS, has anyone, who owned both, noticed any differences(or similarities) in the performance of X1?
Did someone test the fomous GPS lag issue in X1?
I have had a very positive experience with the xperia's gps.Outdoors (inside cars ofc) I can get a fresh gps fix within second. Indoors I usually get it in less than 2min but that prob depends on the building
cheers
Hi.
But what about the GPS lag issue of touch pro and Diamond?, you know, when you move (by car) and you stop then the arrow reaches you after some seconds (instead of stop in the moment), this is, the arrow is always 20m-60m behind you.
I can confirm that there is about one second of lag with the GPS while driving with a constant speed of ~80 km/h. Tested with the latest TomTom. This equates to about 20 m. I have yet to see a GPS receiver that doesnt have any lag though...
Thanks. Thats what I wanted to know

But have you seen any GPS that DOESN'T lag?
I am curious because the few I have seen, internal and external do lag also. I figure GPS by its nature HAS to lag, its the time it takes to get a signal off several satellites and triangulate your position from them.
Hi Alex.
Take a look to the diamod,s forum and touch pro forum and you will see what I am talking about. There are hundred of forum pages talking about it (in xda). I ve used gps devices since 10 years ago. With my latest devices (kaise, cruise) there wasnt that issue. But GPS lag in diamond make very hard to drive in a city. When theorically diamond shows you re in a cross really you are 50 meters passed and I loose many turns. Many people, me included, ve contacted with htc to report the issue and they say their people is trying to fix the problem.
Dani
Ah so "Its lag Jim but not as we know it!".
Fair enough, I hope the X1 doesn't suffer then but I have an external GPS for my Wizard anyway if it did.
hehe,
I ve an external gps bt too but I want to use the internal one. I am very sad about the diamond gps lag problem and I am going to sell it and buy a x1 if, and only if, gps lag isnt a problem with x1
ps: GPS performance is very important to me, did you notice it?

Of course, you're batman after all
Can't have you running into walls with the batmobile.
Well at least if you run into walls with the batmobile, the car isn't harmed.
Besides, if you followed GPS literally you would be driving on the sidewalk and through trees - at least according to Google Maps anyway.
That last few couple of meters of inaccuracy can be a real pain
Exactly!!. My bat-car hasnt windows to protect me against guns and rockets so I need to rely in the gps at 100%
By the way what gps software do you think is best for the Xperia ?

Well, at least you have an excuse!
"Officer, the GPS told me so, fine it! No, i'm not drunk. What's with the taser..."
hi i'd like to know how is the gps compared to the note 2.
could someone make a screenshot of gps test?
thank you
Hi all,
in an app I'm writing I'd need to know whether the current point I am, detected by GPS in on a motorway or not.
Is there any way to do that using Google maps, or another service???
Thanks and ciao
my lg l5 II (E460) the GPS does not work
who has an idea to solve this
Hi mate! OK here's the deal:
I have the same phone. Used to have Samsung i5700 before it. The Samsung's GPS was stronger, faster and more sustainable (durable), I mean it didn't lost the signal too often.
The case with LG L5 II is rather different. I haven't tested it on the road yet (I don't own a car stand for this phone, YET - need to concentrate on the road), but there are problems with it.
In a clear sky it takes somewhere between 20 - 250 seconds to fix me. My old phone (android 2.2) needed somewhere about 15-60 seconds for the same task. Ridiculous.
So here are my top tips if you want your GPS to work - it would not be faster, but it would work. Sorry, but I dunno how to make it as fast as my SAMSUNG was:
1. Install GPS Status and Toolbox: https://play.google.com/store/search?q=gps+status+and+toolbox&c=apps
It is the best application for testing the speed of your GPS. Use it under clear sky (no clouds, mists or whatsoever)
2. Install GPS status - test and fix from this link: https://play.google.com/store/apps/...1bGwsMSwxLDEsImNvbS5jb2NoaWJvLmdwc3N0YXR1cyJd
and read this XDA topic:
http://forum.xda-developers.com/showthread.php?t=2197842
Follow the steps there. It would make your GPS work
3. Install one of those navigation apps:
iGO Primo (paid)
OruxMaps (free)
Osmand maps (free)
I don't like the new versions of Sygic (paid), but you can give it a go too.
With a combination of these apps my GPS locates me - slowly and sometimes looses signal, but it fixes me nevertheless.
I hope someone gives us a solution about this problem AND root for our new LG L5 II - awesome phone, with some problems regarding camera and GPS (maybe because it is cheaper than it's competitors)
Cheers!

Unsure if you are still having problems however I found that for some reason Sygic was killing my GPS and had to factory reset, TomTom seems towork fine. Also see this link as itmay help http://forum.xda-developers.com/showthread.php?t=2197842
