my ameo's gps cant fix satellites

My ameo can fix satellites the first day i got in chicago, but from the second day, it no longer fix. it has been so for 1 week.
i use "quick gps" but the gps still doesn't work. then I changed the server where "packedEphemeris.ee" downloaded from by editing the registry, nothing changed. I've used igo,gps viewer,gps tuner etc., the satellite can be displayed around the picture of earth but they are all red and never become blue or green. ive tried hard reset but nothing changed..
I wonder what's wrong with my ameo? Is it possible that my ameo's gps module is broken? or it's just a software issue?

I have read here somewhere that the GPS Now causes problems with the GPS and caused some lock-ups requiring a soft reset. See if you can find the thread....(hint....search...LOL ) that discusses it. I had also heard that the Ameo had a GPS problem.....that thread is here too.....good luck.
Hope this helps...........Later

i have done soft reset many times and hard reset for several times,nothing changed..i have tried setting the gps program port to com4 or com5 and just like what i did when the gps works fine.The applications can connect to the port and find the gps but it just cant fix a usable signal..

here is the screenshot
please help..

Try GPSView
I find that the best program for getting a lock, it normally works in a few seconds. Also, make sure when you turn it on you are in a WIDE open area. You need a good view of the sky in all directions to get initial lock. Wait until its happily locked onto 4 or 5 sats before fiddling or moving.

i have used gps viewer, and i do test it outdoor in open air, but it just cant get fix in hours.
here is the screenshot while using gps view

Not sure if it will work with your software, but I find that my Ameo is far happier using com1 for the GPS port - I believe this is the software port and com4 is hardware. With com1 I can use multiple gps apps at the same time, e.g. Tomtom and Reperion. If the device has not been used for a while, it can sometimes take a few minutes to get a lock, but no longer than 3-4mins. What I generally do is set one of the GPS apps running as I'm getting my keys coat on e.t.c., then by the time I've installed the Ameo in the car and done my 'preflight checks', its got a fix and I can go.
But deffo try com1 if you have that option.

cant download quick gps
hi can i get some help. i got my new ameo but cant seem to get the gps working. when i tap quickgps all that comes up is download and nothing happens. what might be the reason. do i need to get another gps programme installed?

Yes.
QuickGPS is only for downloading sat data, not for actual GPS tracking use!
GoogleMaps is free and quite good. Microsoft Live search same.
Look for GPSView for ppc as well...
Have fun.

how do you make googlemap work? i mean the track function.

Turn off the MS software GPS management, then get the ABSOLUTE LATEST googlemaps mobile.
I think you set the com port manualy in google, com4 or com5 9600
Its best to use the free GPSView to test out the com settings first to make sure you get the right ones. When you get the right port you will SEE the gps data appear in the text box proving its working. This program gets locks quicker too.
When youve got a lock with that, quit it, then run google and use the same com settings.

Tomtom dropping GPS

Using TomTom v7.450 (build 9028) the device can work fine for hours, but sometimes I start Tomtom and it will find a GPS signal and then immediately drop it again.
When I look at the satellite information, it will do this...
1. No GPS device!
2. Poor signal, are you indoors?
3. Built-in GPS receiver
4. No GPS device!
5. Poor signal, are you indoors?
6. Built-in GPS receiver
7. No GPS device!
and repeat..

Hi, I've the same problem on my Blackstone, GPS works well for days bu from today the GPS signal result discontinuous with any navigation software like Tomtom(various versions), Trackypro and iGO8...any idea? Thanks

I had the similar problem when I first installed TomTom. Which settings are you using? Because I used "built-in GPS" for TomTom and had the above problem. When I changed it to "Other NMEA GPS" with baud rate at 11200 ()or whatever the max is + COM4 then gps started working like a charm. Since then no signal drops, no lag and very quick fix. Not sure if it is just by chance or is it a real fix for the above problem, but worth trying as its working for me. However, it has been 2 days only. Not sure if after a while I will have this problem or not. I am using Tom Tom 7.910 with maps 6.75.

Can You try to set the hardware port from <None> to COM9? Seems work better, the GPS signal still present...but for now I'm at home

I have more or less the same problem !
Using TomTom v7.450 (build 9028) the device works fine the 1st week, but now, I start Tomtom it xan't find GPS device !
I tried to reinstall all without success...
I also tried all the COM available !

using tomtom 7 with NMEA com 4 max baud rate. Works just fine. 8 or 9 sats locked on constantly in open areas

I'm having the same problem, although I don't have TomTom 7. But it doesn't seem to be just TomTom that's having trouble finding the GPS (and when it does, it'll never get a fix).
The Google Maps application also gives me the "No GPS found" attitude.
I've installed the HTC GPS Tool, which does seem to find a bunch of satellites, but they all stay no-fix-reddish.
Are there any guidelines on how to setup the GPS on this thing? I find it a bit strange that my settings menu only lists an option "External GPS", and no "Internal/Built-In GPS".

Can confirm that the dropping of GPS is in other applications.
I use zürich map from Lonely Planet (sure its form 2003) and it will drop the signal in the open.
Have a feeling its internal on our devices.

One possibility is A-GPS.
It is Disabled by default, but it is possible that with tools like HD Tweak or Advanced Config Tool, you, even by being unaware of it, you activated (or better : enabled) it.
To me, it was a winner : after re-disabling A-GPS, my GPS started to be stable again, no matter what port I choosed and how I configured the Navigator program.
Give it a try, could be the solution that works for you

Hi there,
I've just picked up my lovely HTC Touch HD - I'd like to buy the TomTom 7 and the correct maps to go with it to allow it to work.
Can someone please tell me where I can go to stick my Visa card details into and buy please! i'm pretty confused on the TT website and on here there's allsorts of version numbers etc mentioned!
I'd just like to have a stable running TT on my Touch!
Any chance of also having the US & Canada maps working as well as the UK maps ?
Thanks !
Dennis! West London UK!

This is not a TomTom issue. I have same problem with IGo and VisualGPSce.
I use to resolve this issue this way (in IGo or VisualGPS) : I change the baudrate in GPS configuration. Switching 19200 to 38400, or reverse, or whatever : the GPS locks and is stable after few baudrate switches.

Theres some reports that the default "sleep" timeout for GPS is 1 second. Apparently the Microsoft Intermediate Driver only updates every 1 second so it could just miss it and go to sleep!
Try changing registry entry to 2000 (milliseconds)...
HKLM->system->currentcontrolset->GPSIntermediate Driver->Drivers-> SleepOnNoData

Already did it (currently set to 2500). But changes nothing (even after soft reset) : GPS keeps deconnecting/reconnecting as described (not every time; one in a while..).
Thanks anyways !

Just out of interest, do you have MobileJustice installed by any chance?

Absolutly not. Nor any software of this type, nor any software who can possibly take GPS in background..

I had the problem of TomTom getting satelites and then dropping them and saying it couldn't find the gps.
Disabling agps (quick gps) via advance config seemed to sort out the problem

AGPS is *not* quickGPS in my understanding. But this is unclear. For a proof, AGPS comes disabled by default, but quickGPS works out of the box. Can someone who knows for sure, precisely state if AGS and quickGPS are the same thing or not ?
I have disabled AGPS also with HD tweak (but quickGPS stills work..), and I have regulary (2 out of 3 times) this problem.

I had the same problem. Disabling the AGPS seems to have worked but I will wait for the data to expire before confirming.
The problem seems to be when I have poor GPS reception AND poor GSM. They seem to be calling upon each other for corrections but never resolve.
If this is the solution I will just rely on QuickGPS alone which has worked fine for years with TTN6.
Edit: I can now confirm disabling AGPS solved my problem.

had TTN7 running for a few days now.
Can't find the built in GPS. Having to set it to other Bluetooth GPS Receiver.
A bit hit and miss with signal / getting a fix.
I have turned off AGPS as well. Going to try out some of the settings you all have put up tomorrow.

TomTom 7 on iPAQ 614c

I installed TomTom Mobile 7 on my iPAQ 614c but when I run the programme it says theres no GPS receiver in the PDA and i selected integrated GPS receiver in the settings. What's the problem here and how can i sort it?

Hi,
The problem is that 'integrated GPS' in the eyes of TT means 'SirF Starxx' ... You just need to change the GPS to 'Other NMEA', Baud 115200, Port 6 (or 8 depending your GPS settings) ....
FYI, I set HW port on 8, and SW port on 6 in the GPS applet on the main Settings menu.
Dirk
PS remeber, there's now a dedicated forum for HP 614 here

Well that worked now it says "Awaiting for valid signal" and in the menu it says the signal strenght is weak I dont know if this is normal but if i wait i may get signal is that right?

Hi,
Yep, it might take some time to get a fix, but once TT finds the GPS it's up and running.
;D
Dirk

i have the same problem.
I have the tomtom 7 installed.
But always says: waiting for a signal but never starts....
¿Are there any fix to resolve this problem?
thank you

try to go to a empty area that have open sky, the ipaq first fix can take long time (can be as long as like 5 minutes) and it does not work well in place that have a lot of tall buildings, if everything does not work, you may want to contact hp for exchange i suppose.
Make sure you select Other NEMA receiver and port 6 in configure GPS.
There are people saying flashing to unofficial rom will make fix faster but i cannot confirm that other than usually those unofficial rom will include a program call ipaq qk position that can download data to make fix faster

Hi,
Tnx for your ROM The iPAQ QK is indeed loading the ephemeris via internet. But TT is not using these files. It loads instead the data directly from the satellites, which takes longer. The iPAQ files are used by other programs like VisualGPSce or Navio. Hence no difference in getting a fix.

GPS settings for 1.56

Hi everyone
I have recently updated to 1.56.405.1 ROM which also included Radio update to 1.13.25.24. However, I have noticed that my GPS no longer works on this ROM. in google maps, it shows "Seeking GPS satellites(0)" forever.(Com4 port for internal and none for external devices) I tries changing baud rate to different settings - 9600, 57000 etc, but even if I press "ok" after setting baud rate, somehow, it comes back to its original to 4800. How this happens ???? its really frustrating. My earlier ROM (1.19.xx) used to show GPS position using Googe maps.
Can any1 guide me how to make things work here?? Also, can some1 please post ideal GPS settings?

I know this will not be helpful, but I'm using Miri wm6.5 v9.2 which my gps locks on within 30 secs on TomTom, Memory-Map and Garmin. Google maps locks in quickly. I used the default settings (com 4) and all works fine.

The ideal GPS settings are default settings
Program port: COM4
Hardware port: none
Baud rate: 4800
Manage GPS automatically: checked
Any other settings of GPS you should set from GPS application.

Thanks guys...I'll try these and reply you back here. Please do read this thread after a couple of days.

default setting is baudrate:9600 isn't it?

No, read above, please

Can you actually change the baud rate? It reverts back to 4800 when you re-enter the settings, so I can't change it at all.

To,
the person above this post
same here dude !! earlier I could change in 1.19XX rom. but ever since I have flashed to 1.56, i'm facin this problem you've mentioned.
BTW, do you get GPS application working properly or same like mine?? [pls. read 1st post in this thread]
Regards
Ash

If you read up in the internet, you can read everywhere that the default value for the baudrate is 9600, so that the internal GPS receiver is demanded best of all in navigation software.
And you say it would be in 4800 now?

i have the same new stock rom and i have four working gps programs which all also lock to satellites within thirty seconds without ever seeing the settings yet along changing them :S are you guys sure this problem is not self inflected .. i wish i could help but i have no idea how..
the applications i use are route99, garmin, navNgo and another one which i forgot since i dont use that often.

Not true.... i have done a lot of reading into this on various forums and settings can depend on radio's, roms, devices and software used. Also i am using 1.56 wwe and my default settings are 4800, com4, none hardware port, windows manage and my gps works fine, cold start about 20 secs, warm start up about 5 secs depending on location and weather conditions!
Conclusion, well i dont have one yet, i am trying to compile a list of typical settings device specific but it is fairly obvious that there are a lots various circumstances
For those interested in whys and hows heres some bedtime reading for starters:

What I've noticed on 1.56.401.0 WWE ROM is that GPS fix with Garmin Mobile XT is much faster, but the icon on Garmin "home" screen shows as no signal. I can navigate as before, maybe even better, just this funny thing with signal indicator... Any1 else with this issue?

Losing GPS Signal

Hi
I use my 3G with Tom Tom maps and the internal GPS. Always worked ok but about 2 days ago it started only connecting for about 10 seconds or not even finding a GPS signal at all. It seems to find the internal GPS unit but then can't find any signals. Have tried it with an 'external' GPS unit and it works fine.
(I tried Orange support and they said it was my GPRS settings !!!!! - at that point after spending 5 mins on the phone I gave up !!)
Any help appreciated

Have you tried using updating the QuickGPS program?

Hi
Yes - it didn't make any difference however
Thanks

Petez1 there a lotsa options, you did try a soft reset i assume, but you can also:
- check if AGPS (assisted GPS) is active on your phone, if so...disable it.
- use the HTC GPS tool to check your GPS status
- re install TT Navigator, and maybe try another version
- in TT Navigator you can either choose 'build in GPS' or 'Other NMEA GPS', both should work, play around a bit....see if it solves your problem.
Last but not least you could give your Jade a hard reset (whipes all the information on your phone, bringing it back to factory state).
Anyways, i sometimes have the same problem as you, esp when i've used the GPS in another application then TT Navigator (GoogleMaps or Footprints). In my case a soft reset solves it.
Put the bold words i used in the excellent Google search function of this forum and you'll find lotsa information.

Hi
Thanks - I checked all these and did a hard reset but still didn't work. I am getting a replacement from Orange
Grateful for your advice
Thanks

YvW...and i'm glad Orange gives you a replacement, cuz when you've tried everything with no solution at all it's probably a hardware issue.
