GPS without network coverage?
 

I've been trying for around a month to get the GPS work correctly on areas without network coverage but I am still running in circles.

Sometimes I get a lock in 10 seconds, sometimes in 30 seconds but most times I do not get a lock, even when the GPS picks around 8 sats.

Any tips? I really want to be able to use the GPS when there is no network coverage.

I am trying to get this done on my Titan and my Vogue.

Thanks in advance.

You do not need carrier coverage for GPS. Cell towers and military sats are two totally different things and located in two far different places. You can turn your cell radio off and still do GPS also.

Thanks but I know that, please read my post: "Sometimes I get a lock in 10 seconds, sometimes in 30 seconds but most times I do not get a lock, even when the GPS picks around 8 sats."

There must be something I need to do to get the GPS working correctly and I need to figure out what it is.

Re: GPS without network coverage?
 

are you priming the GPS? if yes, with what? GPS has nothing to do with cell coverage unless your using the AGPS fix. even then you dont NEED signal, it will just take a little longer to get a fix. who's your carrier?

Re: GPS without network coverage?
 

I have tried the Holux GPS Viewer, HTC GPS Tool, BAF GPS Toogle, I always get the same result, when there is no coverage, it's very unlikely that I will get a lock, even if the GPS is picking 8 sats.

I just want to get the GPS working when there is no coverage, I mean, no AGPS at all.

Re: GPS without network coverage?
 

who is your cell provider?

Re: GPS without network coverage?
 

Well, that's the point, none, I have no service on these phones now, both used to be Sprint phones but they have no service now.

So I want to be able to use the GPS correctly without cellular service.

Re: GPS without network coverage?
 

well provider has nothing to do with GPS, if you dont want to prime with data usage using a aGPS then I dont know what else to tell you. I cant explain why sometimes you can get a sat and sometimes you cannot or why sometimes it takes longer. I do know that when I was doing just GPS like you I would get the same results. Most of the time it would lock. It locked faster when I was more recently locked previously. At other times it would never get a lock even after I would reboot it once or twice. After waiting so long I would eventually give up. GPS for me on the device is something to play with bc I have a stand-alone GPS unit in my truck

Re: GPS without network coverage?
 

I like the aGPS fix but I still can get a lock with standalone in 15 seconds.

i asked because if you were running vzn with the MR1 update you would have to jump through some hoops to get GPS to work correctly. instead of getting pissy, next time just answer the questions people ask that are trying to help you. my advise would be to delete everything and do a reinstall. that way you can start fresh.

Re: GPS without network coverage?
 

Man...calm down. He wasn't getting pissy, just stating that the phones are not getting service because they are not active, rather than just being out of a serviceable area.

Re: GPS without network coverage?
 

I appreciate your help and I was not getting pissy, sorry if I sounded like that.

I already tried different ROMs with different Windows Mobile versions. I think what I need are some Registry settings or some apps, maybe someone else here has already gone through this and got his GPS working without cellular service.

Re: GPS without network coverage?
 

i had GPS working on my alltel 6800 before i had service on it. all i did was upgrade to a GPS radio then build my rom. i started out with google maps but switched to garmin XT because i didnt want to pay for data. what nav program are you using or are you using it for something like geocaching?

Re: GPS without network coverage?
 

I use Garmin Mobile XT, that's all I need but it's almost impossible to get Garmin to get a lock. At this moment, under clear sky, Garmin sees 4 sats and it still says searching for sats, it doesn't lock.

Do you know what GPS settings did you have in your Alltel 6800?

Re: GPS without network coverage?
 

have you updated to the newest firmware? it should be 5.xx. if not go to garmins site and download it. i could never get a lock with just running the older verison of XT. now all i need to do is fire up XT and less than a min i have a lock, no primer needed. as a side note when you up to 5.xx you can change the arrow to one of the pointers from the garmin garage. its pretty sweet.

Re: GPS without network coverage?
 

Yeah, I do have the latest version of Garmin Mobile XT... I love to be able to change the vehicle icon :)

Re: GPS without network coverage?
 

thats weird. i havent had any problems getting a lock with the 5.xx update. again, i would remove XT and reinstall it. also check your location settings. make sure you have it ON and not 911 only.

Re: GPS without network coverage?
 

I have actually succeeded at this very thing, as my Mogul does not have service anymore. I had the same problem initially, but I fixed it by disabling aGPS via EPST. Apparently the aGPS polling causes programs that access the GPS to fail to sync if aGPS is waiting for data from the cell radio that never comes. Garmin XT and TomTom7 both work flawlessly, with QuickGPS priming I get a lock in about 6-10 seconds.

Re: GPS without network coverage?
 

Would you please tell me exactly what you did to disable aGPS?

Thanks

Re: GPS without network coverage?
 

+2 .

Re: GPS without network coverage?
 

I dont think there is anything in the EPST but you can go here and follow the steps to get into the QPST where we normally go to do GPS settings.

Daved, you need to add in your profile who your carrier is.

And mark, I thought you had everything working on your device. Plus I havent seen you on here in forever. You need to add the carrier in your profile also even though I know you are with Sprint.

Re: GPS without network coverage?
 

I did that before my USB port on the Titan got broken.

I also tried the GPS configuration for India in the Vogue which has a working USB port, heh.

I still need to know how to disable the aGPS... I hope we hear soon from nullifier.

Re: GPS without network coverage?
 

I think you can go to where the Suplagps regkey is and set it to the right mode. I forget where but I think it's HKLM/Software/HTC/Suplagps but I'm not sure.

Re: GPS without network coverage?
 

Did you look over that link and look at step 11 because all you have to do is unckeck it to disable it trying to pull aGPS. Its really just doing it a bit backwards because most of us would check mark those options and and specify that certain info to enable aGPS and speed things up.

Thanks but I wish it was that simple. I already went through this before making this thread:

It does NOT make any difference :angry7:

Re: GPS without network coverage?
 

Hmm.....ok.....well I tried ;-)

Re: GPS without network coverage?
 

Really though, if the data connection is only 1X I find my GPS locks to be slow. Unless on EVDO, they don't come much faster. The Standalone works fine...

Re: GPS without network coverage?
 

Uncheck 'Allowed'... leave the IP settings alone, that's irrelevant if it is not 'allowed'. Roms with GPS enabled will still work when aGPS is not 'allowed'

Re: GPS without network coverage?
 

Doing so would reverse what some of us use to enable aGPS which is what I had suggested but the OP said it caused some USB issues I think and didnt want to. If that was the case i think there were some other issues or settings adjusted personally.
