GPS Location, can it be improved to perfection? - Desire Q&A, Help & Troubleshooting

I'm very happy with my HTC Desire (running on Miui) except for one thing, GPS location: It is always wrong by about 30 - 50 meters. That may seem insignificant, but I were to use it to drive me around with my car, I would take the risk to miss a turn, a radar, or worse hit a tree or someone else's car!
By comparison, my TomTom is much more precise.
I see a lot of pple using their Android phone as a GPS Copilot in their car, so I guess the GPS in their phone must be more precise than mine.
I there anything I can do to optimize GPS location on my HTC Desire?
Thank you for your help

GPS is kind of hit and miss. The only way to improve it is to flash the newest radio if you haven't for it. My GPS works just fine and when it locks on it locks on. It could also be your rom as well. But ultimately all phones are not the same. My phone wont be the same as your phone. So something which I can do you might not be able to do and vice versa. But 30-50 metres is nothing really. Is it just lagging behind?

The maximum precision of GPS you can get on ANY non-military device is +-20 meters, so I'd say it's more about how good your software it at predicting where you are, calculating that from your speed etc.

OK, I have my answer: my GPS on my HTC Desire is just pretty good then.
I use it mainly when walking around in the city to help me find my way in areas I don't know. But it troubles me when it doesn't show exactly where I'm standing (not exactly the right street or the right intersection). I just had the feeling that my TomTom in the car was more spot-on to the right location (and it is also non-military ...)
Thanks

[Q] GPS sometimes can't locate despite having fix on 8 satellites

My almost brand new Desire HD just can't locate me sometimes, despite having fix on 8-10 satellites.
I use GSP Status, A-GPS is on.
One day it locate me in a few seconds, and on the other day it takes 10 minutes, sometimes even more.
Just before I wrote this post, I've reset my A-GPS data, downloaded new and went out to try it. I was walking for 5 minutes and I've got fix on satellites, with good signal strength. So I've switched of the phone,reset A-GPS, download again and still can't get location.
My brother with his HD2 has no problem getting location.
Do you think that I should contact HTC???
thanks
its normal...it all depends how fast the sat..communicates with dhd... i too have same issue...but it is place specific issue not dhd... enjoy man
My one tends to behave like that too. There are many environmental factors that affect the signal of the satellites seen. Also I find that if one app gets a GPS fix, switching to other apps seems not to pickup the coordinates from previous fix.

Mine is faulty too...!
Yes I say faulty, becource my sonyericsson x10 ALWAYS get a lock on the location within 10 sec...
Even when I compare them side by side, the x10 works MUTCH better...
By a 10:1 factor or so...
And it is also mutch more accurate when it is locked on to the gps...
Also about 10:1...
Htc make fine phones, not so mutch gps...
I had a thread about this, here a few days back...

A longshot, but would plugging in headphones help increase GPS signal? I always wondered whether they could make such a mechanism for even boosting the 2G/3G/Wifi signal. Given they've already exploited this for FM antenna...

My gps locks in 3secs in my back garden with only 5 satellites turn satellite layer on and it shows location it back garden not the nearest road SO IT'S NOT FAULTY IT'S NOT THE HARDWARE. It's the silly gps apps you using you don't need them just turn on gps open Google maps that's it the only gps app I use is gps toolbox for calibration that's it as for comparing to the x10 haha a great phone NOT
From England with leedroid dhd techo!
Just reboot your phone, make sure your in the car or clear view of the sky and try again.

Are you shure that the gps antenna is there ?
I have tried to remove the two covers on the phone and didn't see any difference in the gps signal...
But I have been thinking about why there is terminals on both covers...

Well, I'm not too sure where the GPS receiver is located, but I'm definitely sure that the GSM antenna is under the SIM cover and the WiFi/BT antenna is below the battery cover.
The GPS antenna is in the plastic cover surrounding the flash LEDs.

GPS?

How is the GPS? I grabbed the Droid RAZR during the extended return period and I must say, the GPS is amazing! I use GPS a lot so that's very important to me.

GPS is fantastic. By far the best i have seen on a smartphone to date (I'm making a comparison between the Desire HD, SGS2, Desire & iPhone)
GPS connects in between 2 & 5 seconds and i have not had a dropped signal using Navigator.
My 2 cents worth....
I agree. No issues with GPS. locked to within 40 meters from inside a restaurant and once out side got a much closer lock right away. Tested using GPS Status and Google Maps.
Does the nexus use the glonass satellites like the galaxy note? Could someone please run GPS test or something similar and see if it uses sats in the 70's range, as well as the regular 1 - 24.
Not that I can tell:
Great to hear, I was concerned because the gs2 has a very lame GPS connection

My Nexus has a much better GPS than my N900 or HTC Kaiser, although it seems to have difficulty indoors AND you have to enable the wifi to get a better signal putting further strain on the battery.
It also adds almost an extra km to my 13.7 (now 14.5) daily commute. Is this like the 'measuring the coastline of Britain' fractal paradox?
Any stand alone GPS navigation app works?
I am not talking about Google Maps, because that is obvious.
But, apps like Sygic 11.2.x, CoPilot, etc.
Sygic doesnt seem to. Please update my app compatibilty thread with others you find not working!
Want to hear more..
I am using Vibrant and it is very frustrating...
And I heard SGSII is not good either...
I don't know if I trust Samsung anymore
I read somewhere it uses the barometer(not thermometer ) to add another dimension to the localisation process.

Is that using just pure GPS or A-GPS?
This alone would get me to upgrade from Nexus S.
How's the GPS inside a partially obstructed view like a bus or something? My Nexus S takes like 2-5 mins.
NOTE: I don't have a data plan, so not using A-GPS but pure GPS
Hopefully this isn't a pain for anyone, but could one of you fine European gentlemen with Nexus' do me a favor?
Go outside, download GPS STATUS & Toolbox (I want to see accuracy of Meters, not feet) and post a screenshot.
Outside of my house, my Samsung Droid Charge will NEVER lock below 5 meters, while my Thunderbolt and Incredible with lock to 1 or 2.
You may ask, what's the big deal?
Well, it's the difference between Google Maps knowing I'm at my house, or my neighbors.
Thanks!
Can anyone please test if the GPS is usable when data network(HSPA) is disabled, like in Flight Mode with GPS enabled?
Thanks!

Weak gps signal

I had to drive over 200 miles to my destination yesterday and my Nexus lost gps signal probably over 40% of the time. Very frustrating and it caused me to miss a few turns.
My GN's gps doesn't seem to have any problem now that it got signal in a snap and never lost any signal
Mine has always been solid. Quick locks that don't fail.
Quite the change from my old g2x.

Yes I have noticed this as well, but it is historically par for the course for Samsung. My only gripe about the Galaxy Nexus is the GPS. Sometimes it is quick (as in, on par with every other major manufacturer out there), but most of the time it is not. It averages 4-5x the amount of time it takes my Atrix or N1 to get a lock sitting side-by-side, and the lock it gets is less secure and about half as accurate as the other two.
The other side of the coin however, is that this is a HUGE improvement for Samsung, as the Galaxy S phones released last year were atrocious when it came to GPS.
For me the GPS is bearable, and patiently functional, but disappointing.
I have the same problem. My GN lost the GPS signal.
There are different radios available here at xda. Maybe those with issues could try updating radio.
I had some 3g connection issues, so tried different radios, but always GPS was fine.

That might work... Like I said, mine is tolerable and gets the job done, but it is mildly annoying coming from (and being used to) devices with nearly instant GPS lock to ~ 2m, and now having to wait (even a little) for a ~5m lock...
It's just one of those things where you have such a perfect phone, then you go to use something and it works, but you know there is something more efficient on a "worse" performing (overall) device...
i have the same problem with mine. Never experienced such weak signal since sirf star III chips were released years ago =(
Takes ages to get signal, never gives a better precision than 20m, etc
Very disapointing
The Droid RAZR has a great GPS so I'm kind of afraid that the Galaxy Nexus is going to have a weak one. I too sufferers through the Galaxy S GPS debacle. Could never rely on that GPS. Razr is VERY solid.
Sent from my DROID RAZR using XDA App
Considering my last phone was a Samsung Vibrant, the Nexus GPS is a big improvement. LOL
My GPS has been solid on my GNexus - much better than my Galaxy S. My radio is I9250XXKK1
same, my GPS signal is super solid on the Nexus
I'm coming from the Galaxy S2 as well, where i used to get "pretty" quick lock times, but the lock would SOMETIME go wonky around tall buildings (downtown core) and usually would take a bit to lock to 10m
but on the Nexus im getting SUPER fast locks (5 seconds or less) and always around 5m from my location
i think its super great, and although the S2 was good, the nexus is an even bigger improvement - i'm wondering if the barometer really makes that big of a difference
I do edit the gps.conf file for NTP servers though (i change mine to the canada instead of north america)
I removed the north america server and added:
server 0.ca.pool.ntp.org
server 1.ca.pool.ntp.org
server 2.ca.pool.ntp.org
server 3.ca.pool.ntp.org
so you can give that a try
the NTP servers can be found here: http://www.pool.ntp.org/zone/north-america
remember to reboot your device after editing the gps.conf file
I'm having similar issues; losing signal or the Maps application doesn't update. For example, the blue arrow signals that I still have lock but it's signalling that my GPS location is still at a round about like half a mile back....
I was also waiting in traffic today and the GPS put me 100 yards down a road to my right. I know GPS can sometimes get your direction wrong when at a cross roads, but this side road wasn't any where near me in comparison.
I've edited my gps.conf which still has not rectified the above issue and I also have WiFi enabled as this does aid location.
I'm going to do a TB and attempt flashing the latest Google image as my phone will not apply the update OTA for some reason. Maybe this might help
What is it with Samsung and crap GPS; my SII was flaky at times where as my old HTC Desire was much better when it came to GPS.
What radio is installed on your device? There are currently several versions out there, the default being XXKK1 (I have UGKK7 on Virgin Mobile Canada). Open build.prop, or install 'Android Info' to verify. When you flash the stock factory image, try to flash the default radio as well (provided by Google). If your current radio is already XXKK1, then try flashing a different one. Some can be found in the Development forum. Your GPS may work better, since the radio variants are optimized for different carrier/region configurations.

I was driving several miles with GPS cutting in and out, this only happened one day so far though. It was frustrating then though, went driving in circles in traffic for about 10 mins.
Never had this kind of issue with GPS taking that long on any device before
My GN gps has been solid and spot on. I use gps (google maps) almost daily on my commute and it has worked like a stand alone gps! My previous SGS Vibrant and SGS2 had really bad gps.. and i was afraid Samsung would ruin the GN. But thank God the gps works as it should!
My Sprint Galaxy SII is horrible. But my T-Mobile Nexus S is fine and so was my Nexus One. I'm debating if I should go with the Razr if the GPS on the GN is lame as the SII.
The only way the phone finds my location is by Wi-Fi and mobile networks. My GPS isn't working. Sigh.
Check out the apps GPS Test and GPS Status. If you GPS still doesn't respond when standing outside in a clear field with Wi-fi/Mobile networks supporting you need to bring it to a shop and have it checked out.
This is how it started for the Galaxy S
OK, I remember my history clearly because this is how I got burned by the Galaxy S. There were a few reports of bad GPS before it turned into a firestorm. And then lots of apologists saying, "hey it works OK" or, "I don't care, GPS doesn't matter to me". Sorry, the GPS was never functional on that device.
I currently have a GSM Galaxy Nexus import on order but I might be turning that shipment based on these these early reports. I am not taking any chances and getting screwed again by Samsung again without GPS.
And I'm not too happy about the various jackyou builds either. I wanted a phone that was finally supported by Google without having to flash the thing. Grr.

[REGISTRY] GPS Settings overhaul

11th DECEMBER 2012 UPDATE:
With the 7.10.8858 WP7.8 ROM on my Lumia 710 (RainbowMod 2.0.1) I can run the enhanced settings posted originally with battery drain held in check.
I assume this is the same with all ROMs from the Dynamics 2.x family, after a few charge cycles for the battery to calibrate.
______________________________________________________________________________________________________________________
Hi all
I've been tinkering with the GPS settings for a long time to try to combat loss of signal and I've found the sweet spot and it seems to improve matters for a range of phones (tested on LG Optimus 7, HTC HD7 and Nokia Lumia 710).
I've now clocked up over 800 miles with these settings and they work brilliantly, even in the "concrete canyons". Give 'em a go (all other settings remain as default):
[HKEY_LOCAL_MACHINE\System\CurrentControlSet\GPS Intermediate Driver\Drivers\GPSOneDevice]
"QOSPerformance"=dword:255
"QOSAccuracy"=dword:3
"PollInterval"=dword:250
"FixMode"=dword:2

did you also test this in a city with lots of narrow streets near to another ?
could be a problem because you changed the Accuracy alot
Be aware that the GPS is already one of the biggest battery hogs on the phone, and trying to increase its accuracy is likely to exacerbate the problem.
Also, Lumia 900 owners: unless there's been a breakthough somewhere that I missed, you aren't going to be able to edit your phones' registries. This kind of thing requires, at a minimum, interop-unlock.

I've tried it in a variety of places that fit that description and its been fine. My HDOP is averaging 6-12 most of the time. Its basically requesting as low a degree of scope for varience in accuracy as possible. I tried it on 5 and it was great, 3 is even better. Coupled with polling more often and the top performance figure (255) it basically tells the satellites that this is a priority request for pin-point positioning.

Its swings and roundabouts - you can have patchy lock accuracy and better battery life or great lock accuracy and a bit more battery drain. Since I use it for car navigation and its on charger all the time its acceptable. Whilst on charge in my car and used for navigation it loses about 5% an hour on my Lumia 710. To me, that's acceptable to get a lock I can rely on. If I'm not actively using gps it doesn't impact battery life on my phone.
this values is on my HD2 (GPS working perfectly)
"QOSPerformance"=30
"QOSAccuracy"=50
"PollInterval"=500
"FixMode"=3
Wait, it *loses* battery even while plugged in to charge? That's just messed up... it might be usable while navigating on a charger (although I find the default parameters sufficient for that in almost all cases) but I sure as hell wouldn't want to use it for getting around on foot or something. With that said, an app to quickly toggle the settings between the defaults and the high-accuracy mode may well be worth it.
Oh, one more little misconception: GPS is a totally passive receiver. You aren't telling the satellites anything. In fact, they don't even know that you're there. All that BS you see in movies where a GPS satellite is used to locate something on the ground is just that, pure BS. GPS satellites just orbit the Earth continuously transmitting; it's entirely up to the receivers to listen to those signals and, based on them, determine the receiver's location (relatedly, a signle GPS satellite can't be used to locate anything; you need at least three I think).
I suspect what these parameters are changing is A) how much CPU the phone devotes to getting accurate fixes, B) how much power the phone applies to amplifying the signals and processing out noise, and C) how often the phone makes the effort to compute the location (that's the PollInterval). I have no real idea what the FixMode does, although it may be related to some of the other items somehow.
On original settings all my phone's have had issues at times in cities with getting and maintaining an accurate lock. I have long suspected that the demister wires built into my windscreen were somehow causing problems with GPS reception.
With these settings it works flawlessly. Maybe the thread should be renamed with "for people with demister wires in their windscreen" then.

I have happily used Navigon with all live services active for more than 5 hours driving with these settings and on charge in the car. From a full battery I still have around 75% charge left. I'm quite happy with those stats if it means I can rely on locks.
I have the settings permanently set and in day to day use (without prolonged GPS use) my battery still lasts 2 days.
"Relaxed" settings - drain reduced
For those concerned with battery drain, I have tried "relaxed" settings that on an hour of use (all the testing time I had, currently) in an city driving environment allow the handset to charge in car without battery charge losses beyond what the charger is supplying and still give pretty decent results:
Fixmode: 2
PollInterval: 500
QOSAccuracy: 100
QOSPerformance: 10
HDOP varied between 8 and 15 with these settings.
I don't know how much power these settings will pull when not on charge as have not had chance to do any extended testing but expect it to be only marginally more than stock, but better results.
Ok, lots of testing later (200 miles and counting) and the relaxed settings pull no more juice than stock settings, but give markedly better lock stability. Try it and see.

How's the GPS performance on the G3?

Can someone comment on the GPS performance on the G3?
Is it fast finding your location on Google Maps? Is it accurate? And does it work when your inside a building or your house?
GPS on the G2 doesn't work inside buildings, but my SGS3 did (or at least much better. It was also faster finding my location).
Compared to your previous device, is the GPS better or worst? To which device are you comparing it with?
Thanks!
About the same as an S3 which I've come It's pretty good, I use a custom GPS.conf and have an accuracy of 16 feet using 11/20 satellites using GPS test from my bedroom. On the road, it's very accurate and google maps turns with you.
Much better than my g2 on CM11.
Instantly gets location even when using device only GPS.
I agree with gsw5700. Coming from a S3, the GPS on the G3 is much better. Google Maps loads a lot faster as well. Works just fine in my house.
All around better experience on the G3.
This is the best phone I ever had when it comes to GPS, unbelievable to me how quickly it gets my location using the Maps app.. almost instantly honestly..
Nexus 5, Xperia Z2, HTC One M7 would all take a few minutes to get GPS...
I fully expected my first attempt to connect to the GPS system to take a little while. I've always experienced this with other devices before. But the G3 connected nearly instantaneously the first time and every time since then. It definitely surprised me. Sorry I haven't used a G2 to compare it to, but I can definitely say the G3 connected faster than other devices that I have used.
As mentioned by others above. This device has the best GPS on a smartphone I ever used till date.
Location on Weather widget
I agree,it's very fast compared to Nexus 5,maps loads very fast without any lag and GPS locks in immediately
I know this is off topic but I have weird problem.Accuweather widget location is always off by 20 miles from current location,it doesn't matter if I'm driving or stationary or on wifi or LTE .Anyone experiencing the same?
Model LG G3 F400k
Edit:-
I played around with 3rd party weather widgets and location was accurate.I suspect problem is with Accuweather widget(stock)
