I have downloaded the 4.0 update. Now I get a Weak GPS signal alert after it searches for roughly 10 minutes.
I have tried all Com0-9 ports, hard resets, and uninstalling/reinstalling Google Maps 4.0
I have the US Cellular HTC Touch Pro 2, WM 6.5 pro, running the standard ROM.
Is this a HTC hardware issue, Google Maps issue, or USCC tower issues??
I had no problem finding 8 - 10 satellites with the old version.
Using my Tilt2 with stock ROM, Google Maps 4.0 got a fix for me.
GPS is a piece of garbage for this phone, at least for me,
It just never worked again for me since the stock rom (always says seeking satellites 0)
Alos,
"My location" is always is in the same spot (I can be miles away and says i'm in the same place)
I haven't done any research on this two issues, maybe some has my problems too?
Well maybe you should try this.
After I flash a new rom to get gps to work I have to do this.
Run "htcGPStool"
Leave phone outside for about 3-5mins until it gets a lock. After that my gps locks in 30seconds or less
ps, the baud rate for the tilt 2 is 57600- com 4
try the link in my signature for the aGPS cab.
This enables aGPS and changes the servers from the public ones which are configured on HTC (and many other devices) by default to the nokia ones which are maintained better and lead to a faster lock.
After installing the cab, run and update/download QuickGPS and make sure you have a data connection enabled then either try google again or htcGPStool or any other gps utility and see how fast you get a lock then
initial lock might take up to a minute, but locks after that come almost instantly.

Why does one need a data connection for GPS? OK, for Google Maps, yes, but just getting a fix doesn't require one -- or does your CAB do something that /does/ require a data connection?
A while ago I read people enabling bluetooth to get GPS working. Yesterday I disabled the cellular phone and it looked like GPS was locking after this. Not a fix if you ask me anyways...

you need a data connection for aGPS. GPS itself does not need one, but the a in aGPS stands for assisted where it uses your data connection to connect to a server to locate you more precisely.
(My understanding of this is that basically your device sends info to the server about which cell site towers are near you, the server uses this info to tell your device which satellites are best for your location, so your device isn't just looking for every sat. its looking for specific ones.)
Here's the wiki for aGPS
http://en.wikipedia.org/wiki/Assisted_GPS
Theres also a bunch of websites with more info regarding aGPS but its best to have your data connection enabled if you want to use aGPS.

Is "htcGPStool" QuickGPS on the programs list?? If not, explain thank you. As for the baud rate, etc... are you talking about the GPS hardware port? My settings say (none) and Baud rate: 4800???? This I have never messed with, could this be the problem??
ATT Tilt 2 w/ stock ROM...Loaded google 4.0 today with no connectivity issues. I normally able to locked my GPS signal in seconds.....

No, "HTC gps tool" is not the same as QuickGPS and it doesn't do the same thing.
AFAIK, QuickGPS talks to a server and gets info on where/what satellites should be visible for your location, your location determined from triangulation (or some kind of location) of nearby cell towers.
HTCGPStool uses the GPS functionality of your phone in some way that helps subsequent lock on satellites. Honestly, I don't know exactly what/how it does -- but it's not the same as Quick GPS.

Ok, where is htcGPStool??? Looked through the settings and have not found anything that directs me to HTC gps tool.
I have an "external GPS" icon that directs me to GPS settings allowing me to change GPS program ports, and the GPS hardware ports.

QuickGPS downloads the ephemeris data so that it can predict where the satelites are, which ones are visible, and which ones to use. From that data it is able to get a fix faster. There is no fix derived from ephemeris data, and any GPS will work without it. The GPS device in that case must basically just scan channels and listen for enough data to get a fix.
That all said; no problems here with Google Maps.. If I'm inside I'll often get a location approximation based on cell ID's and whatever goes on behind that location calculation and depending upon how the building is constructed I may or may not get a GPS signal eventually. For example my house, no problem, I might see the approximate location for 10s then the real GPS location. At work with heavy beamed roofs and several layers of metal between me and the sky I'll never get a signal inside except beside a window. If I'm outside, I nearly immediately get a GPS fix.
http://www.how-gps-works.com/glossary/ephemeris-data.shtml
As far as I know HTC GPS Tool does nothing except allow you to basically reset the GPS, ie: perform a warm or cold restart on it. Perhaps this will help, vs rebooting the phone, if GPS is not behaving. I very rarely will find the GPS is simply not functioning after a reboot.
This tool also might let you change the COM and BAUD but you would not likely need to do that on a phone with a built-in GPS. Even if you were using an external bluetooth GPS I'm not sure you'd want to change the COM/BAUD here, you'd simply use the COM port you set up with that bluetooth device.
That all said, the only time I don't get an immediate GPS fix in Google Maps is if I'm indoors. If I'm in a light structure, like my house, I'll get a cellular approximation for 10-20s. If I'm at work with many beams and much metal above me I'll never get a fix inside.
Let me try to be more specific.
1. When utilizing the app, it locates me within 3100 meters. (pressing the blue button, lower right hand corner)
2. After about 10 minutes of the upper right hand corner stating "seeking GPS satellites (0)" the screen gives me a Weak GPS signal message.
3. I have tried changing com 0-9 ports, with no luck.
4. GPS is enabled
5. I have hard reset the device and reloaded all my working apps.
6. I have uninstalled/reinstalled Google Maps 4.0
7. I have tried different locations throughout Northeast, WISCONSIN.
8. I have tried it while utilizing WIFI. No luck
9. I have tried the Bluetooth remedy. No luck
10. Waiting on replies from HTC, USCC, and GOOGLE.
11. XDA so far is the only place with anybody responding.
HTC Weather TAB
Just got done talking to a USCC tech rep.
He has stated that he is unable to give any technical help with the Google Map app. (no kidding sherlock) He was not even of any help when it comes to the GPS settings, but he did state I am the second person that he has talked to with the same problem.
Now to see how quickly HTC, or Google responds.
The only worry I have is not knowing if it is a hardware issue that should be corrected by HTC. I noticed the HTC WEATHER tab works fine. is this using the same GPS settings as the Google Map app??
also, I have been holding out on the aGPS cab posted earlier. If, and when, I use this fix I will post the results.

HTC GPS Tool is not a standard app. Some cooks include it in their custom roms. I don't have a link for it handy, but if you search on the forum boards for "HTC GPS Tool" you'll find it.
That said, I don't know how important it is anyway...
ok, talked to an HTC tech. We checked the settings and these where adjusted. Still nothing. Got rid of Google Maps and tryd BING, and still nothing. HTC TF3D Weather tab seemed to update just fine, this gave the tech a reason to dump me on MSN and Google. Do you really think BING and GOOGLE share some programming similiarities????
Did you run Quick gps? That did it for me when I first got my phone.
It is installed under the programs lists.

I think they both access GPS via WM. Maybe HTC Sense (Weather tab) directly access the GPS?
I switched back to an older version which also did not work.
I tried a bunch of different settings and did get it working then today I keep getting a device.exe error and the GPS does not work at all.
Yes I have:
My Location set (not 911 online).
Windows is managing my GPS
Google Maps does not work
Bing Map does not work
IN Advanced Config I have Enabled and Disabled Assisted GPS
I am on verizon.
I searched and came up short on answers. Has anyone had this issue? Is there a fix? What Else can I look for?
TIA,
Dan

On my TP2 the settings are COM4 and 38400 baud. Try those - set it from inside the program - each application typically has a "Manual" setting for the GPS.
use the new bing maps...it's far superior...
Try using Visual GPSce to see if your GPS is working properly.
http://www.visualgps.net/VisualGPSce/default.htm
After installing, go to "Connect" and change the settings to COM4 and 4800 baud.
This is a simple program that shows whether you are picking up the GPS satellites or not, and will often work when other programs (like Google Maps) time out. If you are outside, you should start picking up the satellites within seconds. The bars will start to fill up (meaning the signal from the satellites is being received), and the indicator at the bottom right will turn green when you have a good enough lock for an accurate location.

I disagree, in my opinion the traffic provided by Google is much better. It also includes incidents and construction, and is easier to see at a glance how much congestion is visible.
Bing is prettier, but not more efficient. In my opinion, of course.

Its listed as 4800 baud for the Rhodium countless times on these forums, and elsewhere.
I also don't think it matter that much. On the newest Energy ROMs, the HTC GPS tool is defaulted to 57600 for some reason, and the tool started picking up satellites just fine.
Thanks Guys! I went back to an older google maps and reset all of the settings and finally did get it working.
Any idea how can I enable GPS in Bing maps?
At the moment it only uses location services and that is very much off (up to 500m).
There is no GPS navigation but atleast looking at map would help. Sadly that is only if it knows exactly which street you are and not change it's mind every 30s like it does now.

How to do to be located with accuracy ? Bing Maps is unuseable as such.
change your system locale to US for both IE on wp7 and phone itself and GPS will work.
I was driving yesterday, using Bing Maps and GPS was definitely working. It updated my location about once a second on the exact road I was on.
When I first load Bing maps I feel it uses the 500m Cell Phone Tower triangulation, but it quickly switches to GPS if I have line of sight with the sky.
(I am in UK using HD7)

That's because Windows Phone doesn't keep your GPS on all the time. It turns it on when it needs to use it. When you first open Bing, it will use Cell Towers because it has to turn the GPS on and acquire Satellite Locks. Once it acquires those locks, it switches to using GPS as well.

Sadly after 40 min ride it did not do that at all. I had to press locate me button every 5 min to get new location and it was always using cell towers.
Not fun on MC in town.
At first I was wondering the same, but after a few days it all of a sudden worked and is using GPS.
No idea why it works now, but it definetely already worked before switching the Search language to English. Switching just enabled local search results for me.

Hi foaf
Does Navigation work in the UK or is it restricted to the US like the Bing application on Windows Mobile?

Hey guys,
I tried searching on google but to no solution.
The problem is when I switch off all forms of data except cellular coverage, my location changes to a City where I'm not at. I went to that place maybe thrice since I got the phone.
My location in Maps, Weather or even location saved along when I take pictures will be that other/wrong location.
Its easily fixable by just starting one of the data services, but why should I even face it in the first place.
Its happened on all ROMs and wipes don't fix it. Done a full wipe twice from cwm.
My GPS works normally when I'm using maps, it takes about 30 seconds to get a lock on my location.
Any workaround or solution or fix? (except for not keeping data switched on all the time)
Thank You.
Cheers.

Location without GPS is online service. I hope that answers your question about "fixing" it.

There's three things at play in plotting location: 1) GPS, 2), aGPS, and 3) Geo-location
GPS is the onboard chip functioning alone to pick up satellite signals and lock on them. You can test how well your GPS chip alone works by putting the phone in airplane mode and rebooting it.
All aGPS does is use a wireless signal (Wi-FI or cellular) to help the chip get its first lock faster. Once lock is established the chip is on its own.
From Wiki...
"Assisted GPS is a system which can, under certain conditions, improve the startup performance, or time-to-first-fix (TTFF) of a GPS satellite-based positioning system. It is used extensively with GPS-capable cellular phones as its development was accelerated by the U.S. FCC's 911 mandate making the location of a cell phone available to emergency call dispatchers."
Geo-location uses wireless signals alone to approximate position. Devices w/o a GPS rely on this for location based services.
From Wiki...
"Geolocation is the identification of the real-world geographic location of an object, such as a radar, mobile phone or an Internet-connected computer terminal. Geolocation may refer to the practice of assessing the location, or to the actual assessed location."
Once the chip locks, it memorizes the position of the satellites. So if you had your wireless on to get first lock and then turned it off the chip is still using the satellite locations aGPS helped it find. If you want to test the performance of your chip itself reboot it in airplane mode. Download GPS Test from Play. It'll give you a much better picture of what's happening with your phone. I just tried it on mine and indoors it locked and got down to 15’ accuracy in less than a minute. Conditions affect performance but, at least outdoors, yours should do as well or better than mine. If it doesn’t, it’s a h/w problem.

Thanks, that was a very informative post.
Well I switched on GPS and put my phone in airplane mode and restarted. The Maps App keeps saying "Your current location is temporarily unavailable" and I can't figure how to use the GPS Test yet.
Okay, I did get a lock-on from the Maps and the GPS Test app. I went closer to my window lol . Now I'll see if my location comes up wrong.
Edit:Location came up accurate in weather.
Edit2:Location is accurate in a photo I clicked with everything off.
By accurate I hope you understand what I mean, when all the data goes off the phone should still think its in the place/location where it was when the data was on. Ii.e Surat in my case. But what used to happened before today(gps in airplane) was without data the phone will think its in Pune, which is a 12 hours drive from here.
I'm not the only one who's faced this, some say its a bug in sense :/
Anyways here's a thread I saw earlier
http://www.htconesource.com/forum/htc-one-x-discussion/1042-incorrect-location.html
The answers the guy gets are retarded.
To be sure, are you saying that when only on mobile data and relying upon that, you cannot get an accurate location down to 1 KM?
If so, this sounds like a software issue or a carrier issue.
If your GPS has poor reception then I would advise getting warranty repair. It might have the same issue as the Wifi antennas do.
Yeah just so you know pure GPS is line of sight, you have to have a clear view of the sky to work (no clouds either).

No no.
My location when all services are on shows up fine. But say I have a weather widget and all my data services are off, instead of showing the location detected last when data services was on the widget and other settings will show another city.
I'll explain it with an example.
Lets have a hypothetical country with all the letters as its cities.
I stay in 'S' at present. I have visited 'P' and 'M' a couple of times but I'm back to 'S' now. On the occasion that my data services switch off, intentionally or because of weak coverage. Instead of showing 'S' as my location in the weather widget, app and geotag the phone will show 'P' which I had visited days ago.
Anyone having gps problems? When Google maps does eventually lock on a position is seems to be miles away from where I am, it takes Google maps a good 5 minutes to actually figure out a route.
Currently on China rom 10.4.11
Works fine here. Did you give all permissions in app settings. Settings>Apps>permissions >accept all
I'm also having the same problem at the moment. But in my case gmaps doesn't even detect my position at all. Also on china rom 10.4.11.
I've enabled all permissions, change gmaps to no restrictions on battery setting, still doesn't work.
Funny thing is, waze detect my location just fine.
Any suggestions to fix this issue?
What do GPS Status apps show that you can download from Play Store (you only need free, ad-less apps). You could compare the GPS signal of this phone to other phones you have around.
I´m using a REDMI NOTE 8 PRO for 4 weeks. I´m having trouble navigation with the GPS. I tested it with Gmaps and Waze. In both, there are changes in the route without any change in the route traveled. I´ve already checked all the settings (Battery saver, precision location on Gmaps...) without sucess. Aparently the accuracy is low.
What worked for me was uninstalling maps updates, clearing maps cache. Than install gps status from Google play and from the drop down menu select manage agps and reset it . Hope it helps.
