Just how does QuickGPS work

Hello and thanks in advance for any answers to my questions on QuickGPS.
I have an XDA-Orbit and am running it on Vodafone, not O2. I am also running TomTom 6.x. I find that my GPS acquisition times are not as good as people are reporting. Best case it takes about a minute or so... and worst case, longer than 15 min.
I keep my quickgps files up to date, but just what are in these files? I gather that it gets my approximate location based on which cell tower I am connected to, and then gets satellite positioning info. However, do all cell towers broadcast their location, etc. For example, is using QuickGPS with a vodafone SIM useless because it is looking for an O2 cell tower?
Also, does tomtom make use of quickgps? In my tomtom settings, the option to use quickgpsfix is greyed out. Should I be using quickgpsfix instead of quickgps, or is it basically the same thing.
Thanks again!

Have a look in your windows folder and check out the file size of 'packedephemeris.ee' it should be around 50k. If it's not then as I understand it it's not updating properly. I have a mda compact iii and the default settings give me a file size of about 8k, if I use this TomTom takes about 4-5 mins to get a fix.
After following the instructions in the 'update quickGPS manually' thread and replacing the file I'm getting a fix in about 20 seconds.
However the registry fix doesn't seem to be working at the moment but you can do it manually.

Thanks for the response. I just checked the size of the file in windows and it was 47.7k, updated yesterday. One thing that may be causing this is that I travel quite a lot and often times the last known position of the gps is totally different than where I am when I start up the app. Maybe this is causing the problem.

Just use this file for update. Download it and copy it to your windows folder.

Thanks for the response. How often should I update this file? Daily?

If you update it manually it updates the 'download' and 'valid time' in the quickGPS app so if you have the 'remind me when data expires' I'm guessing it should let you know when you next need to do it.

A slightly better solution :
Replace the following ip's in the register:
Use resco reg edit or any other register editor.
HKLM\SOFTWARE\HTC\QuickGPS\0\0\IP -> htctsvr.htc.com.tw
HKLM\SOFTWARE\HTC\QuickGPS\0\1\IP -> htctsvr.htc.com.tw
HKLM\SOFTWARE\HTC\QuickGPS\1\0\IP -> htctsvr.htc.com.tw
HKLM\SOFTWARE\HTC\QuickGPS\2\0\IP -> htctsvr.htc.com.tw
HKLM\SOFTWARE\HTC\QuickGPS\2\1\IP -> htctsvr.htc.com.tw
Here you go. now just use quickGPS to download the location file.

Just for reference, I did manage to download the file, and replace the existing one. The GPS signal picked up within 15 seconds! This is a huge difference from before.
One thing though... if I update through the quickgps program, my file is indeed about 50k in size, but obviously does not do much or does not contain valid data.
I wonder if the data provided is carrier specific.. Ie, an XDA gets data that will not work on a different carrier than O2.

I tried them this morning and all I was downloading was an htc html login page (3.4k) called packedEphemeris.ee
BUT.... just tried again and it's worked a treat, maybe they were in the process of switching things over lets hope they keep things as they are for a while.
Bonkey how did you know what to use as the settings?
Thanks to all for your help.

The ip servers i posted should work. the have been working for over a week now for me. The thing is, if you adjust the ip adresses in the register you have to do a soft reset to make sure the register keeps the setting. if you check your register now you'll see that the default values are back.
How i got them? easy, google on the file P...ee and look for url's with this structure : http://SITENAME/clm/p..ee

Done the check and truely the reg settings did not stick. Corrected and the settings work great after soft-reset

Thanks for this fix. I've now got a 47k packedephemeris file, so that's better than it was. But should I have a QuickGPS option in TomTom? I'm on 6.020 but I can't see any such option...

thanks for this, worked a treat, I was having the sat fix time issues and looking at the packed ephomeris file it was only 3.7k,
I thought the reason that it was taking so long is that I always update it at home but I never turn it one when I depart, most time at a completley different location.

Hi all
First post here.
I know I am resurrecting an old thread... I found it while googling for a fix for my inoperative quickGPS on my MDA Compact III.
This has failed to connect for some weeks now and it definitely affects lock-on speeds.
Red Baron's solution above works for me - i.e. download the file and manually put it in the Windows folder on the device - but it is a bit of a chore.
So I then tried Bonkey's solution and edited the IP addresses as shown - but this doesn't work sadly.
Should I be putting a www in front of the addresses listed?
Or has there been some change to the addresses?
It's a bit of a crappy piece of software, very difficult to find out if any updates or changes are required.
I'm very glad of RedBaron's solution, it is so far the only one on the net that I can find that works!
Thanks for any advice you can give.

verizon touch and gps...not working after flash

I have read dozens of topics on flashing and gps for the xv6900. I flashed using imcokes unlocker, the new sprint radio/rom and finally omjs rom
now I went into my phone settings (via start - settings - phone location and set location instead of 911 on)
I use gps viewer and open google maps but no gps. should I try returning my location setting to 911 and then open gps viewer? I mean this should work but no go
and yes I have googled and search ppgeeks and xda vogue upgrade. no answer. can I get some help

For the first time, stand outside on a sunny day and be patient, it took me about 3 days to finally get it working solid. Keep the "Location On" setting, I don't think it will work with "911 Only"

okay I did get a satellite (5 really) on google maps 2 days ago outside but nothing since. I will try again but flash and everything was alright it was perfect even just weird. but I find my mogul as well did not pick up a gps signal either. that's weird

I don't use GPS a lot, so no guru on it working, but GPS Viewer, built in the ROM I'm using, picked up various sats for me. I used GPS Viewer first, only to see how well the GPS was in fact working, it seemed to be like a meter on muchsignal it was getting. From what I've seen, if you flashed it wrong, your Vogue wouldn't even turn on, so that shouldn't be the problem. There's really only a few things that come into play when getting it to work so check this:
"Location On", like you already have,
System Settings > External GPS:
"Programs" tab: Port "COM4"
"Hardware" tab: Port "NONE", Baud Rate "4800"
"Access" tab: Check "Manage GPS Automatically"
These settings may come like these as default on your ROM.
I've also seen one reg edit that may help:
HKLM > Software > HTC > SUPL AGPS > GPSMode
Try changing from 2 to 1 or 4, helped some people I believe.

How do you mean by it boots up like Alltell? If you see an image with their logo, it doesn't mean much of anything, it's only an image, you can change it. But it sounds like you ran the RUU (ROM Update Utility) to install the Alltell ROM, which is a key step in upgrading the ROM. But did you unlock it first with ImCokeMan's unlocker, version 2.31 I believe?
Also, press & hold the power and camera buttons, then soft reset, it should but you in a multi-colored screen, the bootloader, what does it say?

[Samsung i780] GPS cannot fix on any satelites

Hi,
I am new here and just bought an i780 in S'pore 4 weeks ago, running on i780DXHD1 (Radio + PDA). I have been trying to use the GPS for weeks using the bundled NavFone but it always could not fix on any satelites. In the signal strength, there is no single bar appear. I tried MapKing, it is the same. When i checked on MapKing GPS data stream, it is always empty. when i checked on the dailpad, the GPS logo is active(not crossed). When i turn off the GPS application, the GPS logo is inactive (crossed). With this, can i assume the GPS hardware is working? But why no data stream? I have tried turning on XTRA, but it is the same. Below is my configuration:
[NavFone]
Software Port GDP1:
Hardware port COM9:
baud 4800
Windows managed: yes/checked
[MapKing(trial)]
Software Port COM8:
Hardware port COM9:
baud 4800
windows managed: yes/checked
Please help.... Thanks!

co6ra,
First off, you need to stand in an open space before you activate your GPS. I uses Agis software too, and based on my experience when you use it the first time, the signal tends to get a little longer than usual. At times, it can even be over 10 minutes before I get a signal.
To assist your time to get the signal, I would advise you to use the Enhanced GPS found in your settings>system. Clicked on the enhanced gps and select Enable in the XTRA Enable. There is no need to select Auto Download (that is, Disable).
This would mean that the device will also use the base stations to assist in finding the location of your device. Of course the downside to it is you will incur GPRS charges.
Try it and see if you can get the signal.

Hi,
Thanks for your reply. For the past 4 weeks, i have been trying all sort of methods; standing at my aprtment balcony, in an open field, in a bus, windows seat, etc. all with at least 30 minutes. When i was at home, i stood at the balcony, turn on my wifi, and kept downloading the XTRA. Sometimes, i cannot see any bar at all; sometimes, i saw a lot of bars, with different PRN number, but all empty (strength 0), and kept changing, but still no fix...
help....~~

I thought GPSGate is some kind of port sharing program? Both NavFone and MapKing is able to connect to the GPS unit, it just could not fix. Is it possible that the GPS is locked?
Anyhow, will try on GPSGate later. What is the recommended configuration?....
Thanks!

Installed GPSGate, and found that now MapKing is able to connect to the port and receive data. When i check on the GPS stream, it always appear to have the first line with data(some figures deliminated with ","), but follows by a few line with empty data (no figure, but a lot of ","). When i checked GPSGate, the status of the input port is always "GPS data but no position". I have tried just now in an open space, clear night sky, for at 40 mins, it still cannot fix on any satelite....
Help!...is this something to do with hardware?

Since you have not flashed to any custom rom (I hope you did not) why not send your device back to the SSC and lodge a complain that the GPS is not working at all.
If they say nothing is wrong, ask them to demonstrate that the GPS is able to lock in the signals.
I know it is frustrating to have features and yet not working. It can be a case of hardware issue. Let's see how the SSC can help you, since yours is still under warranty.
I wish you would be able to solve your GPS issue. i780 is still a great phone. Let us know how it goes, okay?

ya...i am travelling now and expect the GPS to work....should have not trust it will work out from box. will visit the SSC when i am back to S'pore 3 weeks later....

According to http://gpsinformation.org/dale/nmea.htm, GGA is one of the most important stream to provide location data. From the log, it seems like the GPS is not able to calculate the current location at all? What is wrong with the GPS unit???...
Ya...i have been trying to put the GPS on everytime i am outside, in total, i think i have tested no less than 10 hours, but still no luck....

co6ra,
From the looks of your log file, it seems that your GPS chipset might not be working. Those coordinates that you have should come from the base station of the phone.
I tried it indoor, and it seems that there are satellites showing, but just could not get a fix on it too (But then, I was indoor).
Your log file might be useful, especially when you bring your unit back to SSC for service.
P/S: My settings are as follows:
Enhanced GPS XTRA is enabled but Auto Download is disabled.
When running NavFone, my settings are as follows:
Don't worry about the external GPS settings, just leave it as it is.
I will feedback later when I am on the balcony. Please be patient.

Yes, what you said is true, the GGA data is the coordinates of your device and determine your location.

I have sent the same log to Agis and Samsung via emails. Waiting for their reply. Hopefully they can solve this by next week, so that i can use it when i need it most as i am travelling to Malaysia now.
BTW, do you guys think that this might be a locked GPS? Anybody has any ideas? If so, how to unlock?

Locked? what do you mean? It shouldn't be and it should work right out of the box.

i am not sure also...read few article on locked GPS topic, which they key in a code to unlock/activate the gps unit.

No luck. Samsung Singapore support does not even want to reply to my email....
Just happen that one of my colleagues travelled to my local office. Has switched back to my old BenQ P50 and let my colleague to bring down the unit back to Samsung S'pore. They claim that it might be a software issue and saying that they are going to flash the latest ROM to see if it helps.

I went through this same thing, I now have Tomtom7 running perfectly and getting a fix in seconds.
It is highly important that you have a working Sim card, correct GPRS or EDGE settings and that XTRA is Enabled!
Use GPS Gate stock settings! ie. prior to running GPS Gate goto External GPS and select com2, then run GPS Gate and use the wizard and let it find Com2.
GPRS/EDGE should try to connect automatically if not then switch it on, exit and restart GPS Gate. Be patient on the first fix it can take 5 mins, it should not take this long though.
Wait until GPS Gate shows that dark green icon in app tray and has a valid position, once it does then execute your GPS software and use (Franson Virtual com 1) default comport generated by GPS Gate.
GPRS/EDGE can be turned off after GPS Gate shows that it has your position and this need only be done once. This has worked on Omnia after many many hours of failure and frustration.

aGPS fix for VZW

For those struggling with aGPS there may be a fix. I don't know yet, but Telus settings seem to fix aGPS. Set these in QPST and registry.
For Valhalla:
Then just change these and Soft Reset:
HKLM\Software\Valhalla Legends\GPSServer\Mode=2 (the original value)
HKLM\Software\Valhalla Legends\GPSServer\PDEAddress=5C8BC6D8
HKLM\Software\Valhalla Legends\GPSServer\PDEPort=8889
Thank Humpa at PPC Geeks for the above.
-------------------------------
For Custom Roms
216.198.139.92
8889
IP
PDE
EnableAGPS = 1
GPS Mode = 4 (2 would probably work too)

Works great (for Valhalla patch)! I got 5 locks inside my fortress of a workplace again!

Worked for me also!! This is a great find.

would this be the fix for say, i installed balhalla patch, it worked for a little bit, and now i cant get a lock to save my life?

So all I've ever used was the QPST setup described in threads. I don't know if this is the same as 'valhalla'. I definitely am missing any GPS signal all of a sudden. Was also working like 2 weeks ago. Any tips on how to install valhalla with the above setup in lehmans terms. I'm very stupid. I said it. And I know how to get the cab file. Just trying make sense of all the other registry stuff. Don't reply if you can't be nice. Verizon xv6900 NSFAN 1.12 - 3.37.78 Los Angeles.

Valhalla
If you had a connection 2 weeks ago, then you probably weren't using the Valhalla patch (going by your sig) - this was mostly used by people who have the Verizon leaked ROM (like me). The first thing you want to get your hands on is a PPC registry editor. I'm partial to PHM Registry Editor (cause it's free!)
Hopefully, someone will chime in with more information an what needs to be changed. Was there anything on the reference site (PPC Geeks) that serfboreds mentioned?

Go through the same QPST steps except on the gpsOne tab use the new IP and Port settings in post #1.

serfboreds... You and Humpa are my heros.
I made the changes you suggested to Vahalla and I had a lock with 7 sats in about 10 seconds indoors.

DUDE - VZGuy - you are MYguy!!! Thanks to everyone in this post. Problem solved. There lots like me on other posts. I'll see if I can't redirect them here. GREAT WORK!

OK, I admit it, I'm an ID10T.
I didn't back up my registry before starting this gps recovery journey. Now (after reading I didn't have to make all of those changes after all) I'm being told to un-do all of the changes and just change the IP and port.
I have attached my valhalla and htc supl agps registry entries. Would some kind soul please take pity on this fool and tell me the original values I should enter to get back to "normal"? From there I should be able to follow Humpa's instructions.
Imagine, he "searched" for the answer and found it. Will wonders never cease...

Ok, no need for two steps, lets skip the revert to old, it is irrelevant.
Here is what changes you need to make to SUPL AGPS:
EnableAGPS = 1
GPS Mode = 2
Server IP = 216.198.139.92
Port = 8889
And to Valhalla Keys:
PDEAddress = 5C8BC6D8
PDEPort = 8889
The rest of it looks right to me.
BTW - if you really want the default values you can get them here.

Here in southern California, and this isnt working for me, but thanks Humpa

Success!! Huzzah!!

Thank you most kind and noble sir!
GpsGate now shows "GPS data with valid position"! That's refreshing to see...
My GPS software "sky map" now shows many more satellites and is instantly "hot". Also refreshing...
It's nice to see the arrow in MLS sitting firmly on my roof again!
GM instantly finds 5 satellites and locks to my location in less than 2 seconds! It's not as accurate as MLS, but at least it works!
All in all, a very successful rescue!!
Thank you again. Now I will stop grovelling (but still be appreciative none the less).

I am still having some issues. I was using the leaked verizon rom with the valhalla patch and had good gps. Like everyone else mine went out. I switched over to NFSFAN's rom and have tried some of these fixes using PHM Registry Editor and am not having any luck.
Here are some things that I have done that I am not sure I needed to:
Installed Valhalla's patch
I can't seem to get the PEDADDRESS in Valhalla to stick once I enter this: 5C8BC6D8
Thanks to everyone who is working on a fix and to those who can help me out.

Please send me a PM with your registry settings (if MR1/2 send Valhalla and SUPL AGPS, if custom send me QPST and SUPL AGPS) and I will help you get it working.

I have the same problem

Only the 5 remains after entering the new PDE address.
Where do I find the server IP to enter?

I edited the registry, but I need to get this QPST thing going. Can someone help me out?

Follow this thread here.
Enter these values in the GPSone tab:
PDE IP Address = 216.198.139.92
PDE Port Number = 8889
PDE Transport = IP
Position Calculation = PDE
PM me if you have any specific problems after reading and trying the above link.

I have the same trouble. I changed the type to HEX, which let me enter the correct string. When I go back it has changed it to DEC, but it is correct (if you change to hex again). I have done all these fixes just now (3/25) and now GM will find satellites (up to 7 or 8) but cannot find "my location" on the map. Its like it doesn't know what to do with the satellite data.....

Hey guys, I just had to replace my xv6900 due to a giant drop - this after I had just figured out how to get gps running again after all the verizon issues over the last 2 weeks. My question is do I need to unlock and that whole process still using cokeman or do I just proceed with valhalla setup as if it were the MR1 update. This is straight from Verizon store with rom version 3.14.605.1 / radio 3.37.78/ PRI 2.03_002. Thanks for any help.

A-GPS working on TP2

If anyone is interested I have got A-GPS working on my TP2, unbranded standard WWE ROM, Vodafone UK network.
The steps performed are as follows (As always, Use at own risk, make sure you have a backup etc etc...)
Install T-Backs GPS fix http://forum.xda-developers.com/attachment.php?attachmentid=188959&d=1243353858
The CAB above sets the defaults for tha ATT network, the following settings are the ones I use, and should work anywhere (AFAIK).
[HKEY_LOCAL_MACHINE\Software\HTC\SUPL AGPS]
"EnableAGPS"=dword:00000001
"GPSMode"=dword:00000002

Note you will need to change the APN, network and GPRS connection to suit your network
This fix definatly works on my phone, I have analysed the debug logs and the NMEA logs and can see the data being downloaded and injected into the driver.
I now get a cold GPS fix in less than 20 seconds, whereas with AGPS turned off I could be waiting for 5 minutes or more for a cold fix.
To see if it is working on your Phone, first you should see a GPRS data connection established then using the HTC GPS test tool to examine the NMEA data you should see a $GPCELL entry after a few seconds.
Hope this helps.
Tom

hey Tom, something you might find of interest,
I had already set up my agps as you have said above with nokis.supl and my agps was workin great, after reading your post i changed the Reg setting for Ril/driver to 1 and SR ( mine was set to 5) as you suggested. and although i was still recieveing the NMEA info, i couldn't get a lock, changed it back to 5 and Lock from cold in 15 seconds!!
I don't know what the decimal 5 instructs and possibly its radio related? i am still using stock 3.44.25.25.27
Anyway great post

Frogfoot, how does the performance with A-GPS enabled compare to the performance with it disabled? How sure are you a) that A-GPS actually is enabled, and b) that it is A-GPS that is making the difference? I ask, because I can get a lock in 10 or 15 seconds with A-GPS turned off. Simply installing the GPS patch did that for me!

I have found that I get a much faster lock when 'cold starting' the GPS, ie after the ephemeris data has expired (if you havent used the GPS for say a week) or you have changed location by say 50 miles since you last used GPS. Without aGPS a cold start would take several minutes, however with aGPS working it takes a matter of seconds. (there is no difference in a 'warm' or 'hot' start scenario).

I installed the debug tools and could see the procedure calls reading the registry entries, opening the GPRS connection downloading the data etc. And I also used the HTC GPS tool to log the NMEA stream and searched through to find the response from the supl.nokia.com server in a string marked $GPCELL

I expect that what you are seeing is what is known as a 'warm start' where the GPS chipset has cached the Almanac and ephemeris data for the last known position and uses that to jump start the connection. That is fine untill you go for a long drive/flight with the GPS off and then it assumes you at the old location or there abouts. This can cause the GPS to think that the wrong satalites are overhead and therefore take longer to lock on. The other scenario which benifits from agps is if you dont use the GPS for a while, the cached Almanac and ephemeris data expires and needs to be downloaded again. This is what causes the long TTFF (time to first fix)
Quick GPS as far as I can gather is supposed to download predicted almanac and ephemeris data for your region and inject that into the GPS driver to facilitate a faster TTFF however I have yet to notice any difference when QuickGPS is up to date as opposed to it having expired data.
Hope this clears it up a bit.
Cheers
Tom

Very interesting, do you usually connect with GSM or 3G? I have only tested this with GSM, and have not experianced the problem you describe.
Tom

For completeness sake here are two useful apps for general GPS testing
CleanGPS.cab, very useful to reset the ephemeris and almanac data and HTC GPS Test tool for diagnosing GPS fix problems

Apologies if this has newbie written all over it... What would I need to change for this to be compatible with T-mobile US service? Looking at the cab registry keys, it looks like I should be fine as is.
Thanks!

Thought I would mention what I've been using on my TP, very similar with a nice cab.
http://forum.xda-developers.com/showthread.php?t=478199&highlight=t-mobile+agps
The only thing you might wanna change is the connection settings to match the name of your data connection...

For the benefit of us newbies, could someone clarify what changes (if any) need to be made to the above registry values to get this working on O2 in the UK (if this is possible)?

Already test mine using agps setting from frogfoot, but it doesn't work on my TP2,
Frogfoot may i know what Radio version you used to enable AGPS on TP2
Thanks

I know my GRPS connection, but is there anybody know what is "APN"? How can I set it?
I found here the APN setting is empty.
