Quick GPS needed to make Tom Tom work each time??

HTC Touch HD Seems to have a problem with the way this device is handling GPS.
I have Tom Tom 7 installed and when I try to use Tom Tom 7 it looks for a valid GPS signal and then shows "No GPS Device" It will then find a valid signal and then again shows "No GPS Device" this changes every 10 or 20 seconds.......
If I use quick GPS first before I start Tom Tom (even though Quick GPS hadn't expired) it works fine!!!
Confused!!!
Please help!
Thank you

bit odd, mines fine, the only thing that is probably different is i turned off A-GPS, try turning that off, im assuming you havent been playing with its settings?
try a different GPS enabled program and see if that has the same issues.

I have turned A-GPS off and it has locked on almost immediately and seems to be keeping the signal so far - There's a first!
I'll give it a bit of a test drive tomorrow and keep my fingers crossed...
Can you give me a quick understanding of how A-GPS is supposed to work (or not)
Thank you for your help.

It's supposed to logon to a server provided by your ISP, then use celltower co-ordinates to help make GPS more accurate.
It's basically totally broken on the HD.

To get a fix the GPS receiver needs Ephemeris data. This can be acquired in several ways.
1. Direct from the satellites to the GPS receiver.
2. From a data file (QuickGPS).
3. Transmitted from a cell tower (AGPS).
1. The receiver will get a fix without any assistance but will take a while to acquire sufficient data from at least three satellites to do so.
2. The receiver has much of the positioning data stored in a file so will resolve a fix quickly.
3. The data transmitted from the cell tower will take time to be received so will take slightly longer than 2.
If both (2) and (3) are supplying Ephemeris data, then that data may be similar but not identical. At this point the receiver will have a WTF moment while trying to resolve the fix from differing data, and so will rely more on (1).
Throw into the mix a weak cell signal and possibly a weak GPS signal / reflections and the problem is compounded.
Clearly there is no need for all three, and in many cases it is problematic. Keep the QuickGPS data up to date and switch off the AGPS.

Fully understood,, thanks for making it so understandable.

I dont believe A-GPS has anything to do with it, and I have mine always disabled to avoid any potential network charges for using it.
I did have some initial teething problems with getting GPs working but once I got up-to-date s/w and configured everything correctly, things improved dramatically.
Now GPS synchronisation is usually very quick indeed, with lots of satellites visible. Occasionally it wont synchronise but I find a soft reset of the device always puts this right.

gotta love that WTF moment wen it spazzs out.

GPS can't find satallites?

Got this phone today, installed tom tom, google maps and also gps test, none of which can find any satellites.
Tom tom just says "Waiting for valid satallite signal", google maps is the same, and gps test says "GPS starting up".
In the gps settings I have it running on com 4 for software, none for harware and managed by windows.
Anyone any ideas what could be wrong? fault gps receiver/antena?

Did you try standing outsite?
( sorry, tongue in cheek humour )

what about your baud rate settings?

How about trying the Asisted GPS, it will use some data but it helps find your locale.

I tried the supplied Google Maps and my copy of Co Pilot 6. Both acquired satellites very fast with a good lock. Didn't have to do anything special for Google Maps. With CPL as usual you have choice of BT or Manual. You choose Manual and do discovery. It finds it on Com4 at 4800 baud (I think) ... and that's it.

Do you find that the accuracy is good with CoPilot? I've got TT7 on mine, and it locks quickly qith good strength, but the lag is BAD. Don't know if this is a TomTom issue or the phone?

Had the same problem with GPS satelites, mine keep dropping connection so sending back to Amazon now. My replacement arrived this morning so when I get back from work, I'll swap them over.

CPL has always had odd routing issues ... like must Sat Nav systems ... but the lock has always been very accurate.
My TP2 went back after 24 hours due to a screen finish issue so I didn't test widely in the car etc.
I'm getting replacement tomorrow ... will try over weekend.
Again, I'm on CPL6 .. never upgraded because I have factory Sat Nav in both cars now.
I use Memory Map v5 more for walking (have 1:50,000 of the UK).

Mine is working perfectly, GPS is extremely accurate on this phone, with google maps it was litrally watching me walk round my patio outside.
Very impressed

yep i have just tried google maps while out on a boat and in the town got 8 sats very quick and very accurate position

I've got the same issue. No GPS anymore. Wheneber I do a hard reset it works again. So it might be an installation issue?
Franky

Hi all,
For those of you who are unable to obtain a GPS lock within 1 minute, please ensure that you have DISABLED AGPS (it is only supported by a very few networks in a number of countries at present) and also ensure that you have run QuickGPS to download the latest data.
Cheers,
Beasty

Great to hear after all the GPS issues with the Touch Pro and Diamond..things seem to have been resolved witht he Touch Pro2 and Diamond2. My TOuch HD's GPS works great..could be a little more responsive on location, but it acquires 9+ sattelites lightning fast though.

On most inbuilt GPS devices, you can improve lag by lowering the input and output buffer values in the reg, on Rhodium mine was set to 4mb for in and out, dropping these to 1mb (1024) has improved things.
On my TP (Raphael) I was running them at 512K , which was almost spot on.
You can also try the polling, default is normally 1000 (ms) I normally change to 100.
Make sure you Soft Reset after applying new settings to the registry.
Cheers,
Beasty

Mine is also working perfectly, do you try to get satallites on open space with COM4 and 4800 baud rate?
Good luck

mine works great with google maps... not so with garmin xt mobile

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??

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?

[Q] GPS drop out

Brand new Huawei P6 ... GPS horrible!!! .. takes ages to lock on, and then when it does [sometimes] cannot use NAV for any reliable length of time as GPS drops out and stays out .... oh, some times it might come back on again .. but long after the waypoint has been passed making the navigation service completely useless ....
Have upgraded to B111 via the GUI on the phone. Android 4.2.2 but ... no joy.
I have been trying to find a reason .. thought maybe it was app related and that myabe gmaps or nav contributing to the issue ... so installed some GPS helper apps to try and troubleshoot the issue, but they seem to be affected by the same problem ...
I am annoyed and frustrated as i rely heavily on GPS ... the Ascend G600 i had previously worked flawlessly!!!
Has anybody got any clues on this ... :crying:

Try TopNTP. Play around with the settings. One of them might speed up lock on tremendously.
My fastest lock on was 7 seconds, even with GPS cold start. Inside my apartment!

Thnx for the suggestion UpUp ... but unfort no joy either with TopNTP.
So did a factory reset and first up Google Maps Navigation finds my location and draws the route to destination .. even get a voice announcement to send me on my journey ... BUT from that point on the GPS icon continually flashes with a notification "Searching for GPS ..." that continues ad infinitum with the map locked on my initial position ... suddenly it might jump to some totally inaccurate location ... and then finally the voice announces Lost GPS Connection ...
However, on one occassion .. after 'searching for location' for about 15 mins .. all of a sudden my location is pinned as accurate and the navigation went along smoothly for about 3 klm ... then "Lost GPS Connection" again ... never to return!!
I have tried TopNTP, GPS Status & Fix, GPS Fix, Essential GPS ecc ... but no joy!!
I cannot believe just how crappy the Google Maps Navigation is on this highly regarded HUAWEI phone is!!!
Surely i cant be the ONLY one with this gripe??? But at this stage i can find very little on the net about it ... very frustrating!!
PS: At one stage i got GPS Status & Fix to lock on in smart time 7 seconds with maybe 6 out of 9 sats .. but then when i loaded Google Maps Navigation, even GPS Status & Fix could no longer get a fix!!!
Does anybody know if there is an issue with the software Google Maps Navigation????
Help IS neeeeded .. thnx!

Mmm... wonder if your P6's GPS is defective. You should get service since it's new.
I read a lot about slow lock-on, but it is a common complaint on most brand names. Nothing can't be remedied by TopNTP or GPS Fix.

Okay .. fair call .. i was starting to think the same way due to lack of similar cases returned via Google search.
Spoke to their local service centre ... after describing the issue was promptly told to return the phone for servicing, even though i pressed for a firmware upgrade! Even though they would not admit it, sounds like they believed it to be a hardware issue.
So have to wait 2-3 days for an email to arrange pickup instructions .. then 2-3 weeks for resolution!!! But i have no option, save throw it in the bin and try another brand/model ... obviously at my expense! .. wtf ... will just have to be patient.
Will advise on outcome.
Thnx

This is what I did,
go to dialer, press
*#*#2846579159#*#* then go to item5, background setting, next to AGPS settings, change the positioning method to autonomous, on service location, change to supl.google.com. This will speed up the GPS lock. I am using ASIA phone, not sure if your firmware is similar. Good luck.

Alternatively, if your phone is rooted, you can replace the gps.conf file under the System\etc\ with the one I am using now.
I actually got it from the LG Flex and played around with it. It works perfactly. When you have Internet on, it fix the SAT really quick.
You need the Root Explorer to change the permission to overwrite or delete.

Edit: OK, I answer myself. The posted gps.conf file works great on my phone (EU/CZ) and at the moment I get fix in a few seconds.

gps lock

Can someone recommend a good gps app that doesn't rely on Google Navigation? Google maps wouldn't lock any satellites on 4.1.2 and it works even less in kit kat. My wife had a very important doctors appointment today and we almost missed it because it was the 1st time using the navigation on kit kat and to my dismay, it's still garbage!
And I refuse to play the blame game between AT&T and LG as to who is to blame and needs to fix it.

First, let it do an initial fix. Install GPS Status & Toolbox from Play (or don't, use Maps application you already have), go out, enable High precision location (if using Maps, tap on My location button) and wait for a fix. It takes around 5 minutes, if device's GPS wasn't initialised. If devices GPS was initialised but can't get a fix, I suggest installing GPS Status and check the number of available satelites.
osmand uses OpenStreetMap, so you may try with that.

Thanks zamajalo. I think that may have worked but I didn't test it by going for a drive. But I do have to go into town tomorrow so I'll test it on the road then. But so you know, it's connecting to 10 out of 22 satellites. I applied the fix from gps status but also used another app called gps fix so who knows which one did the trick....lol.

I usually have a lock on 8 to 10 satellites on open, so that's pretty much OK. If you get a location fix, there should be no more problems.

Yeah it did the location fix but it said something about it only lasting a couple days?

What exactly? I've never seen that message on my phone or others.

When it downloads the extra content for the gps fix. it gives some disclaimer about how it may only last a couple days before having to download the content again. But it doesn't matter. It didn't work. It kept dropping the gps signal every two minutes and the screen would hardly refresh and show the direction properly. It just sits on the starting screen(your starting point), tells me how far down the road to go, then drops signal, doesn't give you directions anymore, and when it finally does pick up the gps signal it takes forever for it to "recalculate" your position. Oh and losing the signal again. Did I mention losing the signal?....lol
This happened with 4.1.2 also so it leads me to believe it's not a software issue but rather a hardware issue. I:E LG sucks for gps!
