Hello, for about 2 weeks my gps has been working and has been taking a little bit longer than normal to lock. but thats not the problem.
the problem is when it does lock the position will be off by 1/4th mi to about 3 miles and its usually connected to 8 or 9 sats and says position within 10-20 meters
im not very good with the metric system but im pretty sure that 20 meters does not equal 3 miles and the little blue circle is not that big
and keep in mind this is outside clear weather and no big buildings around
i was wondering because i heard that there will be no more funding for the gps sats and would slowly start failing because they wont get the upgrades they need and also i heard about a month ago that there will be some big solar flares that could mess up the sats
another thing is using gps test. is showing that the sats that are connected are lower signal than they usually are. mostly in the yellow. but i see no reason for that...
this only started happening for about a week or 2.
anyone else having this problem? can a radio update fix this? if so which would be the best one for t mobile usa (link if you can)
Radio ver: 4.49.25.57
thanks for your support,
Darian
turn off your agps, as it uses cell tower signals to locate you, and can over ride the gps signal you are getting. the agps is triangulating your position and is generally only accurate to 300 to 1300 meters.
i thought agps was only used to get a faster lock on the sats

According to Google Maps 4.0 my gps is never accurate within more than 20-30 meters. usually when im driving i am on the wrong side of the road or in a ditch somewhere.
on my girlfriend's droid her accuracy is about 1-3 meters at best and is never any greater than 10 m.
same goes for my friends blackberry storm...about 5 meters.
So i am wondering if you guys are having better accuracy with the phone.
is it a hardware or software issue? and any idea on how to make this better??
Thankss
No my gps is very accurate. It could be due to the radio version you are using. You didn't mention witch version you use, but try some different radio's and see if you get a better gps signal.
HD2 GPS is a joke!
My HD2 GPS is very, very lousy - when I record my path (on feet) with e.g. RunGps or NaviCompiter, I am getting an ugly zig-zag line with position errors of 20-40 meters! (In city or in open field - does not matter). Unbelievable P.o.S! My radio is now 2.09.51, was 2.07.51 - same s..t.
My old Samsung i780 draws very smooth line with errors within 1 meter, seriously.
HD2 GPS works with Tomtom though, sometimes turning map around when pausing at a crosing or recalculating, but generally OK.
Unless one is seriously geocacheing or needs absolute precision, I regard 20 meters to be fairly decent, 10m to be fantastic when using google maps. But then again I use GPS and map software as a guide not an absolute... I've always taken the stand that map software doesn't know everything about a location, nor does it know the best way to get there.
I do agree the gps accuracy is dependent on the radio though and some are better than others at getting a good signal
My TP2 accuracy is very good. As good as my Garmin handheld GPS I use for geocaching. I went for a jog the day before yesterday, and tracked my progress with SportyPal (http://sportypal.com) and when mapping my route on Google Maps my position was good to within 3 meters (and usually significantly better). I ran up and down some bleachers and it showed my proper position right up and down the isles.
I've also used it for geocaching, and it usually brings me to within spitting distance of the cache.
The reception is also better than any other GPS I've used. It will usually pick up my position in my office, which is half way underground with an entire second story above me.
So is the GPS receiver on the Touch Pro 2/Tilt 2 better than what is used on the Touch Pro/Fuze? I assumed it was probably the same since most everything else (hardware) is the same. Although you would think that HTC would have fixed it after all of the complaints with the Fuze.
I'm thinking of upgrading from the Fuze, but so far the only advantage is the screen. If the GPS has been improved, that will make a difference.
I have a Hero and have tried several running apps and some are better than others.
I like RunKeeper http://runkeeper.com/home and find it to be ok for accuracy but not perfect. On a clear days it works well but cloudy days its a bit off. I don't think the accuracy issue is due to RunKeeper I think it is the phone. However other apps are terrible for accuracy like Cardio Trainer which shows 4.3 miles for a 5K/3.11 miles.
Here's a map showing what it looks like on a cloudy day using RunKeeper
http://runkeeper.com/user/d12bn/activity/26716842
Showing 3.36 miles for a 5k/3.1 miles measured with a Garmin and my car.
Its not bad but my Garmin would still be very accurate on the same day. So just wondering if the EVO GPS is any better?
Thanks JB
Personally, my gps is spot on. If it says X is 5 miles away, I only have +/- .1 tolerance.
I have not tested it over distance like this, but I do know that I've seen my GPS as accurate as 4m.
I havent tried mine over several different weather conditions but when I have tried it I can watch the little arrow move from the front of my house (facing east for example) to walking around to the back yard and facing another direction... Even if I turn it on in the house, or somewhere else, it always places me w/in the same 1/4 of a block -- I know that's not a scientific measurement, but all I'm sayin is that for me, the times I've tested it, it's pretty dang accurate... Also, I havent tested it over distances when runnin (it is accurate in the car)... But I think I'll give it a shot now that you mention it
Simply better than any other GPS for me so far. I agree on couple of meters difference.
Thanks
Cool let me know what you find. I can say using my Hero for navigation while driving works great. However using it to measure walking/running may have to be more accurate, 3 tenths of a mile short or long makes a difference at the end of 3 miles.

Mine has been as accurate as I previously stated, even when walking.

Mine has been accurate down to 3 meters. Walking down to the park (about 1.7) miles is pretty much spot on in google maps. I just have to tap the little blue arrow a couple of times to "improve" the location before I start walking or driving anywhere.
Longest I've tested it is about 17 miles driving. It was off by about .1 as a prior user stated.
I have noticed that the best I can get on my Galaxy Nexus GPS is 15 feet accuracy with 11 sat locks outside with GPS Test, but with GPS Status it can get down to 5-10 feet accuracy. Which app is correct? Is it the same with your Galaxy Nexus?
Well,
In Australia at least it is illegal to have a GPS that is accurate within 10 meters, because it is then deemed military grade. Therefore every device with a gps in it is either offset or purposely made inaccurate. Thats what that little circle around an arrow or point is on maps/gps units. "You are within x meters of this location" However most of the time, it will give u "your location". This reply is based on word of mouth from several people in high places im in contact with.
Hello everybody,
I have a Samsung Galaxy 551 (GT-I5510) and I have severe problems with my gps.
Normally, it needs about 15 minutes for a gps fix (without agps). To make the fixing faster, I installed a gps-logger to check my position every two hours. By this, I could improve the fixing time to about 2 minutes (without agps).
As the summer gets really near, it's warm outside. Now, I have again problems with my gps. During the past days, I did not get a fix within 1 hour. Then I gave up. I checked the satellite connection with a gps-software. Mostly, I did not have any connection. Sometimes, my phone saw 2-4 satellites (although it was really brilliant weather outside --> no clouds).
I supposed, that the bad connection is influenced by the temperature.
Then I started putting my phone into the refrigerator. After about 10-15 minutes, I took it out.
Result:
Even inside my house, I have connection to 6 satellites. But after about 10 minutes. I lose any connection.
I don't know, how the gps antenna is installed inside the phone. But I suppose, that due to heat expension, I have problems with the connection between gps antenna and the gps chipset.
Could you help me please, to fix this problem? Where is the gps antenna located? How can I improve the connection between gps antenna and gps chipset? Can I install a better gps antenna?
Thank you very much.
Best regards
Hi people,
I have recently bought a Galaxy Tab 3 7.0, brazilian version T211M with 3G and digital TV.
The idea was to use it as an in-car multimedia and GPS device using Waze. I made some tests using my Nexus 7 2013 for this purpose, and it worked flawlessly. So I bought the GTab 3 to be a dedicated tablet for this.
The thing is: the GTab 3 GPS is nowhere near the Nexus 7 GPS performance. My N7 is able to find three or more GPS satellites and lock position in a couple minutes inside my car's garage (which, BTW, is not underground, it's the building's third floor). And without A-GPS (it doesn't have 3G connection, it's the wifi version). In the same situation, the GTab 3 keeps looking, looking... and nothing. Yesterday I went out driving, and it took 15 minutes for the GTab 3 to finally lock GPS position.
Another funny thing that happens is when I stop, for example, in a traffic signal. The GTab 3 GPS gets confused somehow, it's not sure if I'm moving or if I'm stopped. Its speedometer marks 0 km/h, then 2 km/h, sometimes even 10 km/h, then 0 km/h again, the speed keeps going a little bit up, then down. Again, different from my N7, which was very precise.
As a last test, I put both tablets in my place (I live on the 9th floor), over my sofa, right beside a window and a door to the balcony. Using GPS Status (you can get it from Google Play), I tried to find GPS satellites and lock position. The N7 could do it in a couple minutes. The GTab 3 couldn't do it. I had to go outside to the balcony, stood in its end, and then finally the GTab 3 got a GPS lock. But when I go back inside, it loses the GPS signal.
I'm very disappointed about GTab 3 GPS performance, it really ruined my car tablet experience. But before I sell it and lose some money, I have to ask: is there a way to improve it's GPS performance, so that those issues are gone? Or that's the way it is, and I can't do anything about it?
I recently bought one too, haven't tested the gps yet, but comparing with my Note 3 with AGPS, it´s surely much worse.
