GPS Fixes by Carrier

[hetaldp]

Being we are non Sprint User the Assistance Server will never accept Requiest from Outer Network so we must have to put the GPS into Autonomous Mode (Self Fixing)

I am using this Setting in SULP (Secure User Plane Client With Extended Ephemeris)

[HKEY_LOCAL_MACHINE\Software\HTC\SUPL AGPS]
"GPSMode"=dword:00000001
"EnableGPSSmartMode"=dword:00000000
"EnableAGPS"=dword:00000000

GPSMode = 1 means Autonomous (Self Fix no Assistance Required, Pessimistic Approach, Very Slow but Very Accurate)
GPSMode = 2 means Assisted by Server (Less Optimistic, Somewhat Slow but Medium Accuracy Quality)
GPSMode = 4 means Assisted by Server with Extended Ephemeris (Very Optimistic, But Sometime we loose Accuracy Quality)

EnableAGPS = 1 Means Enabled AGPS and 0 Disables it

EnableGPSSmartMode = 1 Save Downloaded Ephemeris Data and also Send it Assitance Server to Update / Fine Tune Extended Ephemeris Data on Server (Require Internet Connection), 0 Zero Desables this Feature

Ephemeris Data = To get Self Fix the Device must know the Position of Satelite in sky, which is called as Ephemeris Data, This is Combined Database which have there Altitude, Latitude, Longitude so the Phone , GPS Device don't have to wait to get Satellites Position from Frequent Satellite Self Position Broadcast by Air

Do you use anything to prime the GPS? I use Quick GPS, which downloads the SAT location info from the Internet to my 6800, and should help speed locks up...but I say should because it does not always work. I was in a cab in NYC on Thursday, and the cab had a SAT lock but I didnt for over 15 mins. Was very frustrating.

I am actually going to change the setting of Smartmode to 1 since I have an unlimited data plan...yea! Next you talk about a SULP client. Where can we obtain this?

Any assistance from you would be ideal. I love to learn.

Okay...tried the mode 1, and that blew. I didn't get a damn thing after that. so, here's what my adventure has taken me on today (again, this is a VERIZON 6900):

* Installed Quick GPS - didn't help that I could tell. The whole "isn't accessed, needs a middle man" argument seems to make sense
* Installed GPS Viewer - I let it run forever and although it kept seeing some sats, it bounced all over and never locked
* Put gps mode to 4
* Ran GPS Viewer again and this time got a lock in about 10 minutes. Not speedy at all, and really only hit about 5 sats (after removing battery for 10 seconds)
* Hit the forums again trying to figure this mystery out

The point I'm at, and again, this must just be becuase it's VZW:
* PPST isn't in my device. Even if I found a cab or something of the sort, I suspect running it would cause my unit to implode
* PRI version seems to be big for the Sprint devices..they have 2.something and mine is 1.37. Honestly, I'm not even sure what the PRI is (the shame...), but I know for sprint folks, it was updated via customization in the sprint 3.02 rom, which non-sprint folk are told NEVER LET RUN - YOU WILL BRICK PHONE and the such...
* I have seen suggestions to allow customizations to run in the sprint rom and then flash the rom of your choice, etc...

I've searched these forums 7 ways from sunday and see so many differing opinions, and largely they seem to apply to Sprint (and a few Alltel folks). But even if I assume the instruction is to let the sprint rom run all the way, I'm pretty sure you can't do that on a VZW phone..and just how would I go back anyway?

[spetrillo]

Ok here is my take on all of this...

I flashed the Sprint "leaked" ROM last night and let the customizations run. So this morning I had a yellow looking phone. I immediately flashed my VZW 5067 kitchen ROM and my phone came up with a solid roaming indicator and instead of saying Verizon Wireless it said Preferred System. After reading the threads I am getting this because I let the customizations run, which updated the PRI. My PRI is listed at 2.03_003 right now and the only way to get back to a VZW phone is to back it down to 1.37, which I guess is the VZW supported PRI.

I do have to say while on the 2.03_003 PRI, and incorporating the GPS that HetaldP mentioned, I was able to get a SAT lock in seconds. I do enable SmartGPSMode since I have an unlimited data plan, and that obviously helps. I plan on backing down my PRI asap and then will re-test GPS.

So based on my experience I would not let customizations run. While the PRI does get updated it screws your phone up. VZW needs to address this asap, and I guess we will have to wait until they bring out a stock ROM.

I have my Bell Mobility Touch flashed with the PPST, and I also have my PRI updated to the Sprint one, just by installing the PPST cab, and running it. I now am able to get a lock much faster than before, and I can confirm this. Before I would have to sometimes wait even up to 3 minutes, and rarely it locked within 30 seconds. Now it locks in after 25-30 seconds all the time, regardless of the phone entering sleep mode or even after a cold boot it takes about the same time. I also set my gpsmode to 4, and I have smartGPS enabled as well. Good luck, and remember you don't have to flash to a clean firmware after doing this, simply just updating the PRI will do. It will not screw up your Bell Mobility Touch at all in any way, I don't get any IOTA errors either.

Any Verzion users have luck installing the PPST cab on the Verizon phone? Or the Sprint PRI on the VZW phone? The previous poster indicates that doesn't work for VZW, and most other comments I have seen say it's bad karma to mix PRI versions and carriers.

Are you sure it's safe to run PPST on a Bell touch? I ran PPST when it was first discovered without thinking what it would do to my phone. At first, GPS locks were fast and within less that 1-2 min. But I started to run into problems with getting slow or no internet connection at all. I did a hard reset and got internet back, I checked my PRI after and it's 1.3 something. So I guess everything went back to normal, now GPS would lock in 5-10 min.

Yesterday I flashed OMJ's latest ROM after flashing the REAL Sprint final release. GPS has been working ok, but after I made the registry settings in this thread I consistantly get 4-8 sats and a lonk in 15-20 seconds.

I have driven 50 miles with no gps application running and after starting GoogleMaps got a lock 5 sats in about 15 seconds.

It makes sinse to me that the Sprint GPS assist server will deny VZW requests and I suspect that much time is spent retrying failed attempts to reach the assist server.

"GPSMode = 2 means Assisted by Server (Less Optimistic, Somewhat Slow but Medium Accuracy Quality)"


Changed my registry key from 4 to 2 and got a lock for the first time since saturday.... hmm. I'll let you guys know how it goes from here.

[elitegunslinger]

I am a Verizon user, I have been trying to get a satellite or a lock for a week now, I have reflashed a multitude of times currently using NFSFAN's v1.12 rom with an altell 3.42.30 radio.


The gps viewer does see the gps on com4 but never seems to get a satellite or a fix.
It repeatedly shows:

GPS Open...
$GPGGA,,,,,0,,,,,,
$GPRMC,,V,,,,,,,,,,,,
$GPSA,A,1,,,,,,,,,,,,,,,,
$GPGSV,1,1,0
$GPGGA,,,,,0,,,,,,,,
$GPRMC,,V,,,,,,,,,,
$GPSA,A,1,,,,,,,,,,,,,,,,
$GPGSV,1,1,0
$GPGGA,,,,,0,,,,,,
etc...

I have used every radio available including the 3.42.50, 3.37.77, 3.37.10, etc.

I am going to go crazy

I have tried the agps fix, Valhalla, reg edits, you name it, I just can't seem to get this running with a gps fix, does anyone have any suggestions?
