Google Maps 4.0 Unable to locate Satellites

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.

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?

GPS is not Very good

The gps is not very good atleast it is not working very well in my phone.
I tried using cardio trainer. And the gps jumps about. Plus the gps signal shown is very low can anyone put their phone gps through the paces and then tell me should I ask for a replacement or its in all phones

Mines fine.
Mine works fine, GPS is actually pretty good as navigation tells you the road names..!

Can you clarify if you're talking about hardware or software?
And did you compare GS with other GPS at the very same time and place?

I too am seeing poor performance with the GPS. Seems to be a hardware issue.
I did a test over the weekend comparing my Galaxy S with a friend's HTC Desire. Using one of the many GPS utilities the Desire was consistently seeing and locking more satellites when stood in an open area outside. When running Google maps and showing the current location I found that the "accuracy circle" (for want of a better description) was growing and shrinking several times a minute causing the map to zoom in and out.
I've also noticed that the compass is almost unusable and showing a much lower signal compared to the Desire. I did perform the figure of 8 calibration several times.

Not tried the GPS yet, but I'm amazed how accurate network location is on this thing.
On my old G1 network location was laughable, but this thing knows pretty much exactly where it is without GPS.

Lol what kind of anti-google propaganda have you been reading?
Google streetview cars collected data of open wifi networks.
Besides from the fact that google doesn't use the data (which it isn't allowed to have), there are by far not enough open wifi networks to find your location.
Also. You have to have at least 3 networks to be able to determine a location using wifi access points.
So the statement you just made is rubbish and ofcourse nonsense...

i dont care about it, i like it.
hmm. just figured this because where i live there arent any open networks and with wifi on it knows my exact location. Without wifi it has a 1600 m radius.

The GPS seems to work flawlessly for me at least.

Google collected the SSID and MAC addresses for all of the wifi networks they found, with the explicit intention of using them as an additional source of location data. They also inadvertently collected more data from open networks, and that's what they're in trouble for.

yes and the new google navigation api in the i9000 and android appears to use this data as the damn thing turns on your wifi even when off when gps tries to get a fix!

nope it is disabled and try to get a gps fix.. wifi still comes on and then goes off.. not sure what it is doing.

I got mine and tested.
In the beginning I had a perfect fix on location. When I started moving, however, I experienced this "jumping around" issue with a huge loss of accuracy. The circle of accuracy was also changing constantly. I think I show something about the wifi seeing (or not being able to see - can't remember) some hotspots although my wi-fi was turned off.
Maybe indeed - the phone detects wifi networks even if the wifi as such is off and possibly compares it to an internal database (thus explaining the persistence of the problem even when the radio is off and the phone is not connected on the net).
Do you know any good free program that would allow me to get some test data - e.g. number of satellites / signal quality etc (unless there is already one somewhere in the interface - I am new to Android).
Can someone else run a test? Can some one run a test in an area where no wifi exists.

That's bad news,i'm really interested in this phone (money-forgiving for a while ),but i need great gps performances...

Try "GPS Test" its on the market for free. From my test the GPS is actually quite nice, several 18-25 SNR connections and a few 26-30 SNR ones ( When outside I even find one or two 31-40 SNR ones which is really great).
Anyway I notice that GPS had become far more accurate when I disabled the Wifi-location option. The only problem is that locking down takes some time ( about 10-20 seconds max) in my area.

ok - i will test with that and revert..
By the way, in my wm6 Touch HD there was a utility called quickgps which would download data from server instead of having them downloaded from a satellite with a low speed connection. This increased speed of cold lock. Furthermore there was also another option to enable assisted gps (not sure whether this was different from the quick gps application and what this did exactly). I wonder whether these application / features are automatically enabled in our case.

It can also be a problem of google navigation beta?? Did anyone try another gps navigator?

i felt the same thing about GPS, as it is not that good , as there's no wi-fi Google can detect hear. the performance was not that good at all!.
but tonight i used the GPS without the Wifi (i turned it off) and for a surprise the performance was amazing, I was with my friend in his car watching the road as he drive and watching the google map in my phone and was very good indeed.
that's strange!.

[Q] Bing Local Search

Hello fellow WP7 users. I was wondering whether people are getting local search results when you search on Bing (i.e., hit the search button). I live in Canada and my wife and I have the Optimus 7 and we never get local results no matter what I search. It always only has Web and News. I was under the impression from watching videos before getting the phone that WP7's integrated Bing search would give other options, like local (maybe pictures?). Anyone else having this "problem"?

I've just tried (on HTC Mozart) to search for "coffee". At first time I've got message that no local results found. After trying again, I've got some local results. The only problem, that the phone still thinks I'm in Germany (I was there couple of weeks ago, but phone still thinks I am there).

Well, at least your getting some sort of local results! But that doesn't sound very good either. I've noticed that when I hit the search button and bing pops up after a little while the name of the city where I live pops up under the voice input option accross from bing. It still doesn't give me local results, but at least it knows where I am.
Where are you located? Lithuania? I'm wondering whether it is limited to certain countries (Germany and the States for example).

Yea, I'm from Lithuania. Bing search displays "Berlin" below. Some other apps (WeatherBug for example) thinks that I'm in Berlin. It looks that the phone somehow cached my location when I was in Berlin and now it can't update it even through GSM/WiFi/GPS even I have location setting turned on.

Intresting. Under "Settings" and "find my phone" do you have "save my location periodically for better mapping" selected? I wonder if deselecting that might help. I'm not sure what "Get results faster" does.

How is that your problem being at home? GPS should pin point your location, but I guess unless Bing does not know that there is a whole world besides USA and Western Europe, I would assume it is Bing problem because it might not have a map data for the region you are in.

I was using Bing Maps on my HD2 and it was able to display my location.

I meant it might not have the POI (points of interest) information for your location, I am trying to see it via bing maps on my PC, and I am getting
The server is temporarily unavailable. Try again later.
EDIT: but now re-thinking it, it might be the bing implementation for WP7 (since it is a completely different platform from WinMo) is not as good as on WinMo.

I live in Amish country (lancaster, pa) and local search does an awesome job for me. If i just search for "Coffee" it shows the local coffee shop as well as the usual starbucks and what not. If i search for movies it shows the local dollar theater and then other movie theaters within driving - as well as showtimes and what not. Local news search also works great.

[Q] Grey signal and WiFi bars?

I was just wondering why sometimes my signal and WiFi bars turn grey and often can't make/send calls/data. I thought no signal or WiFi was indicated differently, especially since I can get full grey bars I doubt it's a signal problem.

it means that you are not logged into google services.
and since most of the apps run with google services (stock browser as well), if you are not logged in, they will not response and keep trying.
if somehow u have other browser like dolphin, or firefox, it should still work.

There isn't a lot you can do if the phone is stock. You can pull the battery often to see if that helps, check your' network settings and make sure that it is all set correctly. Finally master reset and re-log into your' gmail account.
Other option is to unlock the bootloader and root the device:
If you go the unlock/root route I would recommend flashing a custom radio.img file such http://forum.xda-developers.com/showthread.php?t=1374077

I'm already rooted and running the XXIK6 radio. I'll try logging out and back in to see if that helps. Thanks

This happened to me the other day, was so annoying!
Although the blue bars do show whether it's connected to Google services etc, there must be more to it as I couldn't make any calls or anything like that. I went in and out of airplane mode, restarted the phone etc but nothing helped, so I just assumed it was something to do with my network and left it for a while and it sorted itself out in the end.

I have the stock phone. I forced it to see the network by going to Settings, Wireless & Networks, More, Mobile Networks, Network operators. This will force a scan to see what networks are available. Pick AT&T (assuming that who your provider), and it should turn on the Cell Service.
If it does not work, try going to an AT&T owned store and ask for a new Sim Card. (That is what I had to do.) They put it in with no questions, except for marveling at my wonderful SGN. No plan or feature changes happened.
For the Wifi, that is different. Go to Settings, Wireless & Networks, Wifi (and turn it on). You can re-scan for networks anytime. I had 11 networks in range, so it took some looking to find mine. You may need to re-enter the security settings several times to get it right. (Delete old settings by using "forget" below the network you select.) Once it works, it should keep on working with no further adjustments, at least mine does that.
When signals are seen, the grey icons will show blue as a signal strength. (I'm not sure they are accurate.)
Good luck.

All extremely overkill methods...
I used to get this sometimes on all of my Android devices. Simple way to sort it out and sign back in? Your data/wifi is still active - just open Google Talk, go to the list of contacts on it (not in a message, as in you've just signed in) and it'll connect and sync itself straight away... 10 second job, no need to pull out a battery, flash random things, or anything else.

^ this. I just was going to write the exact same thing. Just open up gtalk and you are golden.

Here! Here!
I was pretty shocked to see the suggested methods previous to Gtalk...
If anyone else knows a better way, please share!

Best method is to sort through the code and fix the problem, unless you are all on at&t (which you're not) which would suggest a network issue. However, I have used nearly every android device available...even a few I'm not very proud of. I have never had this issue. My point is Google talk may work and be helpful, but its not a solution/fix.
Justin

It's happened to me a couple of times so clearly not just AT & T nor even just the USA. I waited it out, next time I'll try the Google talk method (not sure if it'll work, Google Voice not currently available in Aus.

Thanks everyone for the replies. I'm on O2 in the UK, so it isn't just a States issue as Clancy is experiencing it in Australia too.
I've narrowed it down today though. I've noticed that I only get grey bars when connected to WiFi, and sometimes even then I can't make/receive calls. Pretty much as soon as I disconnect the WiFi and get connected to the mobile network I get reconnected to Google's servers and the bars turn blue again. Weird.

Location wrong without WiFi/GPS/Edge

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.

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.
