GPS satellite detection - Windows Mobile Development and Hacking General

Hi, I've got TomTom Navigator 6 installed on my Trinity and it all works fine, except it takes about 5 minutes before it picks up any satellites when I run it - does anybody know if there's a fix to enable to gps chip to pick up satellites a bit quicker than this? Even when I'm outside and away from tall buildings it's the same. Any help or suggestions would be great.
Thanks

Did u try that software?

keep QuickGPS updated.

it will save a couple of minutes

aquiring a satellite regardless of whether you're using an internal gps antenna or an external bluetooth antenna usually takes a few minutes when you are booting it cold (ie.. turning it on initally) There really isnt any way around this that I know

Try your GPS antenna with an other software or with a GPS diagnostic.
I am 99% sure your GPS antenna does not work properly or at least try your tom tom with an other antenna.
Info : GPS antenna have to connect with 3 or more satellite to determine the position.

Can anyone shed some light, I have a Route 66 sat Nav and it will not calculate a route. Have done a hard reset, formatted sd card and re-installed route 66 but still no joy.
Pretty obvious, but presumably it is paired with the gps receiver ok and that is getting a lock with a satellite or two.
What gps receiver are you using?
GPS
The GPS that come with system Star111 and yes it is paired, you can point on map and it will find a route but it just won't claculate a route if you put details in. Post codes or cities, roads.

in cold it takes three minutes?
but in hot?

That was in hot by the way, didn't try cold, should be quicker than 3 mins
in hot it is less time not than in cold that gps needs but time to find satellite for the first time not?

sorry, when you say cold and hot, what do you mean?
in cold it means that it is the first time that takes satellite after a soft reset and in hot second or third time that takes satellite. how long in cold and hot?
thank you.

oh, ok, so first time is about 3 mins, after is about 2 mins, but i must say i only tested once. And i can't test anymore now because my mini-sd is broken!!!! Can not format it in anyway, so until my new-mini sd comes, i won't be able to use TomTom, will let you guys know when i have more info.
Anyway, i also need to say, from the test i did, the signal doesn't seems very stable, it keep dropping out and reconnect it again....
time
i use totom 6.030 and I-go 2006 with update from jan 2007
in max 1-2 min location is fixed...
i install ALL cards on microdrive NOT in sd card
i have internal with this microsoft gps programm port 4 routed to port5 ..
regards
I have iGo 2006 without 2007 updates. In cold start it takes a lot of time, abt 2 min on Ameo. In my opinion, more then with HTC Tytn or Asus P525. I didn't measure it with a watch. And also because the GPS antenna is internal in Ameo it looks like the signal is less stable then when you have a GPS device connected to a phone via bluetooth.

I tend to agree with you...I'm using Advantage with iGo2007 and have the same feeling...the internal GPS is not quite stable and it's dramatically worse than used with Trinity. When I'm in desperate need for current location I prefer to use an external BT GPS than Athena's internal one.
It seems that it does not react properly, since the connetion seems to be OK.
Just a side note: the GPS receiver seems to be placed on the side bearing the HTC logo, not on the side with the Opera hardware button... I tried to use Tomtom in my car with the PDA upright (joystick at the bottom) and it didn't manage to get a fix... When I turn the PDA in landscape mode, with the HTC logo on the top, it works a lot better (cold fix in the car after 1 or two minutes).

I don't find this. I have a TomTom mkII bluetooth as well as the Ameo. I find that the Ameo is often quicker to get a fix. TomTOm navigator 6 I find the slowest. friends tell me that Igo (with the 2007 maps) is much quicker at getting a fix.

I find this hard to believe: I think the fix is made (or not) by the GPS chip itself, which gives the current position to the nav software every second. The time to fix should not depend on the software.

Tomtom 7 Locking on

Tom tom 7 wont lock on to any satellites. I have tried astro gps launcher and others. It shows in Tomtom that it finds satellites but they are not blue like when it locks on, they remain Grey or just don't move at all. Can anyone help me?
Are you using a bluetooth GPS reciever or the internal reciever? I'm not sure if that matters at all but if your satelites arent locking on go to the GPS configuation menu and select whatever option you use (ie internal or external bluetooth) if external bluetooth press select then likely com 2 I would assume.. thats the default setting. Once thats done it should connect shortly after. Sometimes when tomtom starts for me it locks on right away other times it seems to have issues connecting to the receiver. IN order to use the internal gps recevier you have to be running one of the roms thathave activated it. If you havn't (just covering all bases here) then that could be why.. cause your internal gps isnt activated. NOW if it is activated and you still arent locking on make sure you're outside and leave it sitting there for a few minutes. It should lock on as thats what most people have had to do when first getting it to work.
If that doesn't work I'm not sure what else to recommend.

what rom are you running?
There have been a few roms around here that perform terribly with GPS locks, sometimes requiring a few resets for it to lock properly.
Can you get a lock using Windows Live?
I can say that TomTom7 works fine with astro launcher. The settings in TomTom work both for internal gps, as well as other NMEA gps device: com4, baud 4800.
If you're using the internal GPS antenna in the Vogue after using Astrolauncher and letting tomtom load go to your gps setup in tomtom and then choose "other NMEA GPS reciever", then baud rate 4800... then com 2. That worked for me. Took a few minutes the first time it got a lock. watch the satellite status screen, should say poor GPS or something at first... and you should see grey bars at the bottom where its normally blue when you have a lock. Thats when you know the internal GPS antenna is on.
I have the new gps sprint rom WM6.1 and also tried quick gps and it takes like five to ten minutes to connect

GPS Phone Calls??

Just wondering... when I go camping far up north, there's no reception on my HTC TyTN. But, using a bluetooth GPS receiver I'm able to navigate with my TOMTOM or Google Maps. Now just wondering... since there's GPS reception, any way to use this GPS reception for phone calls? Somehow? There are GPS phones out there right? So what about making this work?
By GPS, I guess I meant Satellite.
satellite phones use different satellites than GPS units.
so...no.
Any way to connect to phone satellites with bluetooth receivers?
Hi - no you would need a completley separate phone to do this. As far as I remember calls are quite expensive.

Just an FYI. Your GPS receiver can only receive signals from the satellites. It can't send them to the satellite, so no two way communication would be possible even if they used the right satellites.

You probably meant that "it can't send them".

Gps trouble

hi guys
just bought the p3470, and already in trouble =)
i tried the tom tom and first it said that there wasn't any gps device available, now it just says that is waiting for a valid gps signal... forever and nothing...
i have a tom tom one in the car and sometimes this happens but not this long and eventually it works, this one doesn't...
Any thoughts?
I appreciate the help.
Thanks
Nuno
internal GPS of our Pharos is really slow : you must wait more than 10 minutes before having a valid GPS signal.
not on mine .. i dont get a gps fix in my house (only if look for a good spot) but its a question of finding the right settngs. or have it automanaged (ive read on orange roms gps is on com9 ...on my rom its on com4 at 4800 baud)
Here's what worked for me.
Download a free GPS program like visualGPSce. Then turn off the External GPS management in settings, and go outside for a nice walk or whatever.
Then, start up visualGPS and walk through the ports until you find something that works (doesn't complain about no communication). In my case it was COM3. I've seen other reports of COM 4, 2, and 9.
Visual GPS will complain right away if there's nothing on the port so you won't waste too much time. Once you find something, turn the microsoft External GPS management back on (I used COM 5 as the software port) and wait. You might also want to install QuickGPS so that it will find satellites faster.
I had to wait ten minutes outside under full sky for it to work, but that was the longest I ever had to wait. Visual GPS has lots of nice bar indicators and the like so you have something to look at while you wonder if your GPS is screwed.
If that doesn't work, you may be in trouble. Go through all the ports again and be patient if it says it can't lock on to satellites.
It now takes me about 1 minute to get lock on (assuming QuickGPS is up to date). It's a little laggy when driving but reasonably useful.
