[Q] GPS is accurate with wifi but not data plan - HD2 Windows Mobile 6.5 Q&A, Help & Troubleshooting

Alright, so I'm not sure if this has been covered or not, used search but haven't really found anything helpful. When I'm using Google maps with my data plan (T-mobile US), I get a GPS location roughly a mile from my actual position. However, when I enable wifi, my position auto-corrects to within a few hundred feet.
I've already edited /etc/gps.conf for US usage, just wondering if there is a way I can get the GPS to work accurately with my data plan. I'd use GPS Status to try and reset it, but my android build (shubCraft 1.5 CyanogenMod) freezes up, haha.
If anybody can direct me to a possible better android build with accurate GPS or help fix mine without changing builds, I'd be greatly appreciative ^.^
I know GPS isn't fully accurate on the HD2, but I figure if the wifi can get accurate readings, why not the Data plan.

have you got the gps settings correct?
On my (UK) phone the gps is more accurate than my old Navman, and also a lot faster. It updates routs changes in about 3 seconds and is accurate to about 50 yards or less. I use IGO8, but the settings used are
Com 4
manage gps automatcally
gps hardware port none baud rate 4800
I have not used the HTC gps tool, quick gps or google maps

GPS Instructions w/ new Rom for TomTom and LiveSearch

Everybody has been stating that they got GPS to work, but only some left instructions. I hope this helps. Thanks to those that gave me advice on how to get this working.
Make sure unter "External GPS" that the "GPS Program port:" has "COM4" selected. Leave "Hardware" alone which is the next tab over.
Then under "Access" make sure "Manage GPS automatically" is checked
Live Search for some reason wouldnt work until I got in my car and drove away from my house. Right when I drove away, the GPS kicked in, and worked as if I had an external GPS. My settings for Live Search are "GPS COM4".
In order for TomTom to work, you first have to get your GPS location in Live Search, then launch TomTom, and then TomTom will work fine as if you had an external GPS.
My TomTom settings are "NMEA GPS receiver" then "com 4" then baud is "9600".
These are the steps i took to get GPS working with the new ROM update using the internal GPS. Havent been able to test the Rev A yet. But it seems everybody is stating that is working fine, but only some were able to get GPS working.
Hopefully this will help you all to get GPS working with the new ROM. W/o me doing these steps, I wasnt able to get GPS working. Also please note that I had to leave my house for it to work. With my Bluetooth GPS receiver I could get a location in live search or Tomtom w/o leaving the house. But for the internal GPS, i had to leave the house.
Have you tried with google maps. For some reason i can get GPS signal in my house with google, but not with live. Also, under the GPS hardware, does yours say none, and baud 9600 or 4800?
Edit:
Never mind, I got it working, live just connected in my house. I have baud set to 4800, don't think it really matters. (anyone know what baud is anyway, and what the best settings are?). I wish there was a way to do this without live though.
baud is just another word for bits per second, its the connection speed of the hardware, since its internal it probably wouldnt make much of a differnce

I have everything working but tom tom 6. It says no GPS device what gives? Do you have to have Live search running in the background for tom tom to work. I close Live Search after aquiring five satellites then launch tom tom 6 and all I get is no GPS device. hehe I know this is a beta and not a release rom. I have no Idea how people can aquire a satellite in their home. Shesh I have a huge solarium and still have to go outside.
what do u mean you get five satellites? Also to answer your question, what i do is after getting the GPS fixture in Live Search, I just click start and go to Tom Tom, without doing anything to live search. It seems to close automatically when I open Tom Tom.
Does anyone know if the GPS signal comes via the Sprint towers or is my phone communicating directly with the satellites in the sky? I ask because getting a signal inside my house seems unreal.
GPS signals come from satellites which is why the signal degrades when you move inside, eventually becoming nonexistent or unreal.
When someone says they are getting five satellites it means that is how many signals their device is receiving and using to triangulate its position. It requires at least four satellite signals to triangulate a current position and the more signals it can pick up on the more accurate the triangulation.
Ks.
when i said "unreal" i meant unbelievable i have a globalsat BT308 (which is kind of old, i bought it in 2000 or 2001) and theres no way i would ever get a signal inside.
so even if i go out of sprint reception area i can still communicate with the satellites right?
For some reason I always have to setup the GPS device in TomTom. It works but as soon as I close TomTom it looses the GPS settings. Then I have to run through the setup again...
Anyone else having the same issue?
My GPS wasn't working at all until I turned on GPS location under the phone menu. Location Settings under services.
Once I turned that on my GPS started picking up satellites with in 5 seconds sitting in my house.
Does Anybody know how to get the GPS to work with iGo 2006? I am having no luck at all getting iGo to recognize the GPS device.
TomTom appears to have a bug where it does not see the port windows gps port sharing is showing because the hardware port is set to none (I think it's actually com1 for the real hardware). As a result until something OPENS the port for tomtom, it's unable to attach to it. Until this is fixed you have to launch some other program that does work first and leave it open for tomtom to open the port.

Theoretically, you should be able to get a GPS signal anywhere in the world.

I understand that they can selectively disable regions now. (read about it in the paper when they unfogged the signals) so conceivably,we wouldn't be able to use our moguls in iraq or afganistan.

I think what they do is place devices selectively in those locations that send out false GPS signals to confuse the NAV devices. (probably from ground based stations or on moving convoys that are trying to NOT be detected)

Has anyone gotten Garmin Mobile XT to work with the internal GPS?
I am going to hold off on Flashing and give DCD some time to mature the release since I already have a G10 bluetooth reciever and have no issues but it would be nice to be able to leave that in my car and use internal when I'm not in my own car.
As far as i know...these are govt sats that are "open to the publuc." In a state of emergency or other situation, they can be blocked or certain areas can be blocked so only, say, certain govts/military could use them. This was the only way the us govt was willing and able to let the gen pop use the sats.

aGPS updates done, strange symptom?

Hey all. Here's my config:
DCD 3.2.6
Radio 3.42.50
PRL 51056
PRI 1.35_002
I've also applied all of the QPST changes per gc14 with the PDE IPs, settings, etc. I've also verified that my default reg values are correct.
So I can now lock GPS outside within 2 minutes or so after applying all the patches. I do use GPS Viewer to prime, but am seeing a strange thing in all GPS progs now. GPS Viewer as well as iGO8 will flash 10 gps signals for 1 second every 5 seconds, then the signals will disappear, repeating this forever. I assume these are aGPS signals but i'm never getting a "lock" inside, only outside, even though my cell signal is fine inside. Anyone seen this problem, or have any idea what i should check next?
Thanks,

Does the "GPS" section of FieldTest.exe show pilot phase/strength/time offsets? These refer to pilot PN offsets (i.e. tower sectors), as far as my understanding goes. If you are using standalone GPS, my suspicion is that you won't see any data here, however, not having the capability to do standalone GPS on my device just yet, I can't be entirely certain.
Worth a look, though.
Me too

Yup, I have noticed this as well. Happens to me regardless of Radio, PRI, or ROM. I see it a lot with HTC GPS tool. Dont know what it means but I eventually get a lock. I think VZW still sucks and the PDE servers are not as good as Sprint maybe? Im not seeing the "5 seconds locks" everyone else is. I am however getting very fast locks, maybe 20 to 30 seconds. Nothing more than that though. On occasion I still fail to lock but far far less than I used to without the PDE infomration. I dont know what it is but I can confirm what you are seeing.

My Fieldtest doesn't have a GPS Group, so no info there. Any other ideas?
Sorry, it's FieldTrial.exe and not FieldTest.exe.
At least with the MR1 ROM, there's a Debug Info menu where you can select GPS to dump GPS debugging information.
When using AGPS on my device with VZ Navigator, this is updated with tower information. I don't have a device that uses standalone GPS, nor a device with a different ROM other than the MR1 ROM, so I can't really speak for that unfortunately.
I'm not completely certain that you won't see the PN-related fields filled in using standalone GPS mode. However, from my work at hacking on the V740 some time ago, I suspect that pilot phase values are going to be related to cell triangulation (time offset of the signal from the cell towers being used for triangulation against the current CDMA time when the signal was received by your device, i.e. propagation delay).

Hmm, maybe we are getting somewhere, but I dunno since I have never used FieldTrial.exe before. I just fired it up and the entire GPS tab shows N/A for EVERY field. Does anyone else see that with a working GPS?

Okay, I think that you're operating in standalone GPS mode.
Rationale:
With my device (on MR1), when I access the GPS through the custom interface that LBSDriver.dll uses (i.e. via VZ Navigator), I'll start to get data in FieldTrial.exe (on a fresh boot, all the fields are N/A). Of course, the latitude/longitude are garbage (having not been through the decryption logic) as shown in FieldTrial.exe for me, but the rest of the fields (e.g. altitude and GPS time, as well as cell tower triangulation data) show valid data.
To me, this indicates that FieldTrial.exe is just pulling AGPS-related data and not standalone data.
Can you try disabling the phone radio entirely (via Connection Manager or whatever the app is in your firmware) and see if that changes the lock speed at all? If not, that's further credence that you're not using assisted GPS. (Caveat emptor: I don't know if disabling the radio will also turn off standalone GPS, as I don't have any way to check that. It should be pretty immediately obvious to you if it does, though.)

GPS issue...Any help is appreciated!

Please Help!!!
I love this ROM, but I cannot get good GPS quality with it. I know most people have no issue with this, but my GPS on my phone has always been finicky. I updated to Build 13 and Build 13 R2...and neither one allows my GPS to work. My GPS worked (although not really well) with all the other builds.
Here is the wierd part, when I travel out of my hometown (sarasota, FL) my GPS has always worked better. I work in Ocala and with Build 13 my GPS worked the other day, but not when I got home. I tried with the tweaks listed below and I tried before installing any tweaks, no luck...
I installed these tweaks:
GPS Registry - Alltel: http://forum.ppcgeeks.com/attachment...0&d=1237009140 (direct d/l link FYI)
Turbo_GPS_Settings: http://forum.xda-developers.com/showthread.php?t=496800
Any help would be great, because GPS is my favorite feature on this phone.
**edit: I am using Google Maps**
Edit/Delete Message
did you check your GPS signal? I recommended checking it out three times...
I checked the GPS Watcher program if that is what you are asking...
In Startmenu, System Tools, GPS Viewer,
COM port #4, or simply COM4 4800 BAUD and hit OPEN wait 20 seconds or so until signal settles down.
Please post signal(numbers inside bars) and number of sats detected.
That software has a bug that when you do get a fix, it doesn't tell you until you switch tab back and forth.
Reason I'm asking for this is that I want to make sure your GPS unit can receive signal before messing with anything else.
Reg hacks and roms are not going to help if your GPS unit is defective, right?
here is a screenshot of GPS Viewer. This is from Ocala, Fl were my gps works fine. When I am in Sarasota, fl (hometown) the GPS viewer finds no satellites.
From the looks of the numbers, it seems like to me that either your phone is located so that sky view is obstructed with something metallic or your inside building with windows. Right?
One you posted above is when GPS is operational, so, by comparing this screenshot with the other screenshot with GPS non-functional it will greatly help out in finding what is actually wrong.
As you might have figured out already, I prefer data collection first and then action later.
This might be a redundant question, but have you gone into your phone settings to make sure that Location settings are turned on? After that make sure that AGPS is enabled.
Yes NFSFANs rom has those settings by default, but thanks.
Here is the GPSViewer when I run it at my house. I had to leave it outside on my table for about 3-4 minutes and this is the signal I recieved. There were a few more bars but by the time I picked it up and ran CapSure they were gone...
Both were taken on a clear day outside of a building that obstructs the view slightly, but not enough to have much difference.
Oops I forgot the picture, here it is:
Did this happen recently? Some satellites go offline and online periodically and you just may be happen to be in the area where signal dark occures.
or
Test with other Touch Pro phones nearby to confirm your GPS module pretty insensitive or not.
This is all I could think of, good luck.

It has been weak since I have owned the phone. It has however worked in Sarasota 90% of the time and works in Ocala all the time.
The main issue I want resolved is why my GPS worked on NFSFANs 112 Rom and before, but doesn't work on 113 R1-3
Can anyone else help with this?
Can anyone tell me if that GPS Viewer app will display MPH (as opposed to km/h).
The GPS on my TP seems weak/inaccurate as well. I had a Mogul before & the GPS on it was dead on. I have had 2 TPs; the first one was horrible @ acquiring a signal. Even after using QuickGPS, it would still take forever outside. The one I have now acquires much faster, but tracking still is not as accurate as my Mogul.
I just did a hard reset and now my GPS doesnt work. It was fine before, I have the current MR1 rom update, and all was fine before. Now it just wont find any satellites. I have all the settings right, location on, Com4, 4800baud, managed by windows... I dont know what else to do other than another hard reset. I called verizon tech support, no help there. We did try VZ navigator, and it worked.

Change your radio. Happened to me and that was the culprit.

[Q] GPS lbstestmode settings

I have been messing with lbstestmode on froyo for a some time mostly changing different supl servers and changing gps operation mode. I cant say that any of that helped gps lock much faster, but today under SUPL/CP settings I set AGPS Mode to Control panel. As a result I am getting now relay fast and accurate locks 5/7 satellites with less than 15 meter accuracy. My quiestion what the hell is it, and can anyone conform that if works better that stock settings?

Interesting. I too have been messing with my GPs in every which way. I recently had to ODIN and have been running stock settings with the AngelDeath file for my US region. Locks have been taking a while, sometimes never, but are very accurate when they do.
I tried this and I'm picking up 11 and locked on to 6; but it's in my office where I usually do not get any locks. I'll check it out on the drive home tonight and report back.
I too would like to hear from someone that knows what the "control panel" setting is.
I have been messing with lbstestmode on froyo too, but before that I was trying many others app like fasterFix, GPSaid and GpsFix in ECLAIR then my gps started to not locking at all.
So I decided to upgrade to froyo since we have it officially, so I updated and hard reseted it, but the problem stills remain, it's like the gps is not working, just blinking in the statusbar...
PS: I'm from south america, meanwhile I'm rooting it to change the ntp..

[Q] GPS Location Questions

Can someone explain or send me a link to understand the differences between the three location options?
I keep getting the stand alone GPS "warning" and it's annoying. I've unchecked in the settings, but doesn't want to stick
Thanks in advance
Verizon Location Services (Tower Location) - obtained from data collected from local Cell Towers. This is less accurate but quick. This info is used combined with aGPS to give the GPS sensor a head start in quickly locating your location.
Stand Alone GPS - uses the location obtained from your GPS in your phone. Generally very accurate as long as you have access to the satellites. Working indoors can be iffy especially if in a large building. Uses battery power WHEN being accessed. Uses aGPS to give it a head start which is obtained from...
Google Location Services - Uses location information that Google can determine based on network access to websites etc... Wifi hotspots... etc. Typically less accurate and can be widely inaccurate at times as it may use the "address" of the IP block you are using which may not be anywhere near where you are.
Personally, I leave GPS on and leave it at that. IF it is being used, the GPS Satellite will show in the notification bar area and uses more power. If the satellite icon is not showing, it is not using power.
Thanks krelvinaz, that is exactly what I was seeking. Will follow your lead and leave the GPS alone.
Follow up question, how do you stop the "stand alone" GPS warning that comes on quite often
