Buit in GPS in HTC phones

Hi,
Got a HTC pharos today in replacement of a touch (broken, change by orange many times last month but since they only provide crappy refurbished mobiles....). Pretty satisfied so far. I don t miss htc cube that much... I don t miss Wifi yet (only use it when on holidays, that is to say almost never muhaha). GPS is nice... No more bluetooth head to carry in my already too full pockets.
So, let's start with my problem). It has a built in GPS, just like the cruise. After toying a bit with my new phone... and after I have configured the gps, I have noticed that a GPRS connection is launched each time I launch the GPS (TomTom that I had to install since those stupid techs from orange thought it was good to remove from their rom and replace by by their ****ty home made navigator).
Have you noticed that kind of connection. Do you know how I could prevent this (even though it doesn't cost me a buck, since I have set a blank GPRS by default). Could be a thing or two that could be modified in the registry but cannot find it yet...
Sorry I post in the cruise section but there is no pharos section yet (please Admins.... listen to my prayer)

your phone may have "assisted" GPS (AGPS) enabled, thats why it is attempting a data connection. This feature is designed to locate you faster when the satelite signals are week.
You may/may not need a registry editor to disable this feature...

That phone does have aGPS, if you don't want it trying to grab a data connection go to Start/ Programs/ QuickGPS select Menu/ Options and de-select the "Auto download when data expires"
I find that if you use the GPS daily you don't need the aGPS data, it will work just as well without. Also TomTom itself could be requesting the data connection if you have enabled any of the Plus services - Mike

right ...
AGPS = Assisted GPS
HKLM/Software/HTC/SUPL AGPS/EnableAGPS
1 = on
2 = off

its a free file commander / reg editor / ftp client .... all you need

Hi
Thank you for your help. Couldn't find the quick menu so I edited the registry like Aleph305 said. Working perfectly. Now the GPS starts a few seconds after I launch TomTom.
I do not use plus services so I will not miss AGPS a lot.

Quick GPS Help

Hi,For some odd reason my quick GPS does not work anymore. My TomTom is non functional as well. I have checked my data connection and it is active. Can somebody help please.
Thanks in advance.

Can somebody please assist? I have checked my data connection and it is working. I have internet connection, for some strange reason Quick GPS and TOMTOM is not working. Is there a setting somewhere to activate this?
Thanks

Can somebody please assist, I really would appreciate a fix to this issue.
THANKS

I am having an issue with my GPS, except I got my unit 2 days ago, and can not get the GPS to work at all, with OEM rom or with any other custom rom. (it wont work with garmin xt, google maps, HTC GPS, or GPS tweak tools).
I hope I dont have a bad unit.

Strange thing, mine worked fine for about three weeks and all of a sudden it stopped working.

did either of you notice the unit getting *really* hot just before it went out? ...as in I-stuck-it-in-my-pocket-and-now-I-have-crotch-scars kind of hot?

When you say that quickGPS is not working, what do you mean? It doesn't display the page with the "Download" button? You press the "Download" button and it can't connect? It connects but never finishes downloading the data? What are the specific symptoms you're seeing?

I see the quick gps download button, when I click download, the message that I get is connection failed. My tomtom as well does not work anymore. I do have inetrnet connectivity, it's just the quick gps and tomtom that is not working. Please assist. Thanks

Patience

I've had my TP for 3 days now. As with the Kaiser and my hermes Holux bluetooth device it takes approx 5 - 10 mins to get the initial fix on satellites after that it appears to be working fine. Google maps, my old TTv6 all working fine. Takes about 30secs from startup to pickup Sats and shows about 5-7 sats everytime.
So just be patient with the initial startup. It should come.

What are the values of the registry keys HKLM\Software\HTC\QuickGPS\SNTP\Server1, Server2, and Server3? (I have values like xtra1.gpsOneXTRA.net.) What happens if you type that address into Internet Explorer or Opera?

When I type the address in internet explorer I get to the RX Networks webpage.
My internet is working fine, it's the gps thats not working.
Thanks

Well, QuickGPS is an Internet app, not a GPS app. All it does is download a week's worth of satellite ephemeris data from one of those servers. When you reported "connection failed" as the problem you were seeing in QuickGPS, that seemed to indicate that you weren't able to connect to the server.
So if you can get to the server, as it appears, maybe the message is about connecting to the GPS unit (to transfer the ephemeris data? Not sure about the architecture of the GPS here). What values do you have in the "External GPS" pages on the System settings tab? Have you tried the GPSTest tool? Is it able to connect to your GPS unit after you put the appropriate values into its "GPS Settings" page?
If GPSTest isn't able to connect to the GPS unit, then I think you probably have a hardware fault and should exchange your phone for a new one.

Can Someone tell me what is the exact job of the Quick GPS which is in Programs ? for me was expired and i just update through gprs and then show me some valid days remaining.
is it help to connect to satellite faster or something else ? and what happen if i don't update it? thanks.

When using WiFi, QuickGPS seems not to work if it's the first program to use the connection. If you make an Internet connection with some other program first (e.g. PIE), QuickGPS will work over WiFi. At least that's my experience with the stock AT&T ROM.
This problem doesn't seem to occur with GPRS/3G/HSDPA connections, only with WiFi.

Yes, QuickGPS reduces the wait for getting your position when you first start up a mapping program.
The way GPS works is that the GPS receiver uses the positions of the satellites and the distance to those satellites to calculate its own position on the Earth. That requires knowing very precisely where the satellites are at any given time. The satellite position information is called the ephemeris.
Each satellite, in addition to broadcasting time signals (which enable the GPS receiver to determine the distance to the satellite), transmits its own ephemeris. A GPS receiver starting up from scratch has to receive the ephemeris data from each satellite it will be using before it can figure out its own position.
QuickGPS eliminates the need to receive the ephemeris data from the satellites by sending a week's worth of ephemeris data over the Internet. The GPS receiver can use that immediately instead of getting it from each satellite in turn. That significantly reduces the TTFF (time to first fix), i.e., the initial wait before you can start using a GPS-based map program.
The "expiration date" is simply the last point in time that is covered by the ephemeris data sent by QuickGPS. After that point, you have to get more data, either from QuickGPS or from the satellites.

wow, interesting, lots of new and useful information for me that i didn't know that before. thanks man.

Not seeing any 10 minute delay like you saw. Are you updating current sat location data with QuickGPS? I notived using GPStest and MS Pocket Streets that Sat connections go up and completely down all the time. Nice thing is, GoogleMaps ignores the quick downs so it LOOKS like a good connection that never disapears. don't know if this is intentional on Google's part, but it works, even standing still/walking (once connection is made). Lovin the Sat view whilst I use GPS for directions.

Same here: Quick GPS cannot connect... What is this? Maybe a server fault, or do I need to Hard Reset?
LE: Fixed it: I just run Connection Setup again, then it suddenly worked.

i just did a hard reset and quickgps will connect only after i open up a browser and googlemaps sits at seeking gps sats. i had it working 2 days ago and then my battery died and it hasnt worked since. i did notice that the phone was really warm though.

quickqps hasnt worked for me for a couple of weeks now...and i still havent fod anything to fix it

O2 XDA Serra (Touch Pro) - more GPS problems

Sorry - not a development issue as such but I'm hoping you guys can help with another HTC Touch Pro (A)GPS query. I have read a number of other posts on this but they appear to be inconclusive and I'm not sure if the problems widely reported elsewhere are supposed to have been resolved in the latest shipped ROMS.
I'm experiencing very long acquisition times with the internal GPS on the O2 XDA Serra (just released in the UK), to the point where the GPS is virtually unusable. Cold lock can take anywhere between 15 and 30 minutes, even in open ground in good weather with a clear view of satellites. By comparison, a Garmin eTrex Vista in the same location gets a lock in seconds. I never expected the XDA Serra to equal the performance of a dedicated handheld GPS but I would have expected it to get an initial lock in less than 5 minutes in clear sight.
If and when a lock is acquired, it seems to hold OK and I've experienced no major lag problems.
I'm using Tom Tom Navigator 5, Memory Map Pocket Navigator OS 5 and Google Maps. I've also installed a couple of GPS utilities from this forum - Chartcross GPS Test 1.04 and the HTC GPS Tool v1.1.1.0. These are all configured to point to COM4 at 38400 baud (as per advice in this forum), and I've never had a problem detecting the GPS.
What is bizarre and frustrating is that there is absolutely no mention of GPS functionality in the supplied O2 manual, other than a brief warning about not operating a GPS while driving. The XDA Serra is not supplied with any GPS software or utilities out of the box other than an "External GPS" utility in the System folder, which is completely undocumented. I'm unclear in what circumstances you are supposed to use this utility, but I'm assuming it allows you to set a hardware COM port for an external GPS device (presumably bluetooth?) and select whether or not it is managed by Windows. I've tried turning this off but it appears to make no difference.
I'm aware that the XDA Serra is AGPS capable but I'm unclear exactly what this means in this context (i.e. which particular AGPS technique it actually uses), and how - in the absence of an explicit Program or System setting - my installed GPS applications are supposed to invoke it. I have checked the relevant registry settings in HKLM\Software\HTC\SUPL AGPS:
EnableAGPS 0x00000000 (0)
GPSMode 0x00000002 (2)
Number Fixes 0x3b9ac9ff (9999999999)
QoS Accuracy 0x00000032 (50)
QoS Performance 0x00000059 (89)
Server IP 10.1.101.63
Server Port 0x00001cb6 (7275)
TimeBetweenFixes 0x00000001 (1)
... and can see that the AGPS function is currently disabled (the default), but is this supposed to be enabled programmatically by the GPS application, or do you have to set it explicitly? If the latter, how can you do this other than by hacking the registry?
I have followed advice in this forum about disabling GPS logging (it was disabled by default) using the Schapman Advanced Configuration Tool v3.3.0.0. I have tried enabling the AGPS function using a registry editor, but again it appears to make no difference. In addition, I could see no evidence of it having downloaded an emphemeris file anywhere (unless it's hidden in system ROM), which I presume is how it is supposed to work? If I enable it, doesn this necessarily mean that any of my GPS apps will actually use it?
I have tried using SeaSGEE to download emphemeris data to no avail - it downloads what looks like a good packedEmphemeris.ee file OK but it makes absolutely no difference to performance. I have since uninstalled this and deleted the //windows/packedEmphemeris.ee file.
Finally, if I connect an external bluetooth GPS adapter (the Emtac BTGPS) on COM6 I generally get a good cold lock in less than a minute. I used this all the time on my old XDA Mini S (HTC Wizard) and never had a problem.
So, basically, I'd like to understand how native AGPS works on the Touch Po, how it is supposed to be invoked by GPS applications, and whether there are any tweaks I can try to improve performance over and above the ones I've already tried. Is this a problem that is likely to be improved in subsequent ROM or Radio versions or is this simply a fundamental limitation of a crappy internal GPS chip?
Any advice greatly appreciated.

AGPS
AGPS is basically a utility for operator to be able to track your device for various local ads etc. It uses servers to track instead of GPS.For example Google maps would be able to track your position inside building but with tolerance of a few miles (I guess it is your closest tower) Seems to be some kind of bug when operating with regular GPS (in my case it shuts off GPS every 10-15 seconds making Tomtom unusable.You should see settings for AGPS at Settings-System-AGPS. Disable both tabs. On tomtom use other wired GPS receiver at Baud rate 38400 com port 4. restart after setting AGPS. It did work for me.I have Fuze - same as HTC Touch Pro. Let me know if it works better.

This is exactly how the Fuze is acting. Cold locks (after a soft reset or power off/on) take up to 30 minutes to get. But once you do get a lock, things work as they should. Even AT&T sales reps sat there with me, with 3 different Fuzes and witnessed all three phones doing the same thing. It must be the built in GPS chipset. The Sprint Touch Pro I had for a week, never had any cold lock issues.

I was worried that O2 had modified versions without the GPS module becuase I have never managed to get a lock with the device. Nomatter what I do GPS doesn't seem to work.
It is annoying as I've managed to fix every other problem the Serra ships with. Including getting rid of the default home page for opera when launched vial TFL3D. That was a huge pain in the ass as the XML file cannot be deleted or modified easily, it is an undying file. Damn file protectiona and access rules on WM devices.

is there still isues with gps on this phone?
i'm due an upgrade, currently using a diamond, and find gps is fantastic, locks in a couple of seconds nearly everytime, even after not using it for week still seems to get a fix in under 20 seconds, was looking at the touch hd as i thought it was essentialy the same phone, buf beefed up a bit, but i use gps 3-4 hours everyday, so far this phone seems perfect apart from the gps issues..
i've tried searching but can't find any clear information about it, seen various tweaks but no one can confirm it definatly works, my phone's primary use is gps, would i be a fool to upgrade to the serra?

OK. I had the same problem, never got locked on GPS.
It is ALL software issue. Flash different rom, new radio (recommend 20M1) and use tomtom7. Older tomtoms for some reason do not invoke gps receiver on touch pro. GPS on serra works perfect, on mine it takes about 20-30 seconds to get satellite lock. Relax Just flash rom different that the o2 one.

The GPS is rock solid on my XDA Serra with fast GPS start-up times with the PROven ROM - http://forum.xda-developers.com/showthread.php?t=444653.
I did have GPS problems with the standard O2 ROM, as others have said it's a software issue.

All issues have been SOLVED
Hi. just go to this post and you will have a gps lock in a matter of seconds. enjoy. thanks

Yes I just updated my ROM and the difference is HUGE. Almost instant connection with my GPS.

Yes, apparently O2 removed QuickGPS because at some point they planned to enable their own AGPS servers, but did not get round to it and forgot to add back QuickGPS.......

[AGPS] The Universal AGPS Project - Let's get it working!

Okay, so here's the deal. If we get AGPS working in some way, we can get MUCH quicker GPS fixes (30 seconds or less). I'm the coder for GPSToolPro you can find here in the Software subforum of the Raphael forum. I'm hoping to incorporate this into the program in some way.
I've managed to obtain the Lat/Long coordinates using Cell Tower information and Google.
There are two ways to solve this issue.
#1
Now, I'm looking to use these Registry Keys
HKLM\Software\HTC\SUPL AGPS\ServerIP
HKLM\Software\HTC\SUPL AGPS\ServerPort
HKLM\Software\HTC\SUPL AGPS\GPSMode
The plan is to set the ServerIP to 127.0.0.1 and run any port. Then the GPSToolPro will listen in on the port number on the device and RESPOND with the Lat/Long information obtained from Google. Right now, what I need is, somebody who has AGPS working with their provider to try to packet sniff and get see how we can make our own AGPS server run on the device. GPSMode mode will be set to "1", not "2". This is specific to the QualComm's GpsOne unit. The values are the following:
0 - Standalone - Your handset has no connection to the network, and uses only the GPS satellite signals it can currently receive to try and establish a location.
1 - MS Based - Your handset is connected to the network, and uses the GPS signals + a location signal from the network.
2 - MS Assisted - Your handset is connected to the network, uses GPS signals + a location signal then relays its 'fix' to the server, which then uses the signal strength from your phone to the network towers to further plot your position. You can still maintain voice communication in this scenario, but not 'Internet/Network service' ie Web Browser, IM, streaming TV etc..
4 - MS Assisted/Hybrid - Same as above, but network functionality remains. Normally only in areas with exceptional coverage.
Click to expand...
Click to collapse
I haven't been able to find the signal strength of the tower I'm connected to yet so right now, I'm limited to mode 1. Also, I can only find information on the tower I'm currently connected to, not all of them so I can't try cell tower triangulation yet.
This solution is limited to only working with HTC GpsOne devices.
#2
We can also try using the IOCTL_GPS_WRITE_ASSISTED command. This command will directly send the AGPS info to the GPS device. The question is, how do we send this information? I believe we need to get a AGPS signal first, use IOCTL_GPS_READ_ASSISTED, parse that information, figure out the format, get Lat/Long from Google, format it in the same way as received from IOCTL_GPS_READ_ASSISTED and send it back with IOCTL_GPS_WRITE_ASSISTED.
This universal for all Windows Mobile phones.
For method #1, I need somebody who has an HTC device with a working AGPS signal (from their provider or whomever).
For method #2, I need any Windows Mobile device that has a working AGPS signal.
I say method #1 requires HTC device because supposedly AGPS isn't standardized and one manufacturer's AGPS format may differ from another.
Hopefully, with the your help, we can get this working.

let's support CLShortFuse iniciative, it would be incredible if we would get AGPS working.
My AGPS (Spain-Orange) doesn't work at all. And i don't know anybody that has a working AGPS device/operator combination.
I've read around XDA that some people in the Raphael CDMA section have AGPS working, maybe we could post there to see if somebody replies and can collaborate with this project.

I was just about to post something similar. Only I wasn't as prepared with as much information. I was going to try to start a thread to consolidate the AGPS server settings for each additional carrier since I'm with T-Mobile and using an AT&T Fuze. My AGPS is not working at all. It keeps trying to connect to AT&T's Media Net and naturally, it fails.
Would it be possible to maybe create some kind of way to trick the devices into thinking that they are AT&T Fuze's and connect to the Media Net to connect to AT&T's AGPS Servers?
I Personally support this project 100%!!
Side note - Has anyone gotten AGPS working on USA T-Mobile at all? I attached a screenshot of the result of what happens when I try to use AGPS on my Fuze.

I dont know much about any of this, I have an AT&T Fuze with AT&T service, I also have the AT&T Navigator Software and an account with it, so, is there anything I can do to help? how do I know if my AGPS works or not?

Actually, there are AGPS standards. Today, most GPS chipset vendors use their own AGPS platforms. However, that is rapidly changing. To my knowledge, most (including Snaptrack/GPSOne, aka Qualcomm) support 'secure user plane location architecture' or SUPL. This is a standard adopted by the OMA or 'Open Mobile Alliance' (www.openmobilealliance.org). The OMA is basically almost all of the heavy weights of wireless including Silicon manufacturers, Handset Vendors, Carriers, etc.
Currently, the OMA has ratified SUPL v1.0 and the standards body and members are working on the next version - 2.0.
What is SUPL? In a nutshell, SUPL is designed to support location determination regardless of the location server used by the mobile carrier. As the number of applications grow for LBS, so does the need by developers to work across location platforms and mobile device hardware manufacturers.
CLS, I am a bit confused as to your intentions. The Raphael supports artificial ephemerids (Qualcomm's GPSOneXTRA) which cut cold-start TTFF down to under 10 seconds. Using cellular triangulation won't buy you much.
Is there another reason I am missing here?

If your AGPS is working, your GPS should lock in just under a minute every single time, sometimes even faster. With my old Sprint Touch(back when I was with Sprint), I was able to lock onto upwards of 7 satellites every single time in less than 10 seconds. Now it takes 2-5 minutes every time with my Fuze on T-Mobile.

I've never had my Fuze lock it's GPS 10 seconds or less. NEVER. It's usually 2-5 minutes on average. Sometimes it doesn't even lock at all after standing outside in the cold for upwards of 5 minutes smoking a cigarette.

Dharvey:
I get 3D position fixes in open-sky conditions in ~6 seconds.
Under my balcony in my apartment in a highly attenuated partial-sky view I will get 3D fixes in ~20 seconds.
Indoor in my home office with a south facing window and light foliage I'll see 2D in about 1 minute and 3D almost always under 2 minutes.
At my corporate office with a re-radiating GPS antenna I'll see consistent GPS lock in ~6 seconds.
Hell, I'd love to put this in the multi-channel GPS simulator at my desk but I don't think that's a good idea.

Yes you definitely have working AGPS
I made the registry changes mentioned above and I'm about to test my AGPS now. If it works I'll make a cab file to make the registry changes for everyone who may want it. (T-Mobile Only of course)
EDIT:: Making the following registry changes seems to have helped a little. My GPS locked in about 1 minute in my bedroom from a cold start(after soft-reset) It also connected to the data instead of error-ing out which was also different.
FROM:
[HKEY_LOCAL_MACHINE\SOFTWARE\HTC\SUPL AGPS]
"Network"="MEdia Net"
"GPRSConnection"="MEdia Net"
TO:
[HKEY_LOCAL_MACHINE\SOFTWARE\HTC\SUPL AGPS]
"Network"="T-Mobile Data"
"GPRSConnection"="T-Mobile Data"
EDIT AGAIN:: I just soft-reset and from a dead cold start(GPS OFF COMPLETELY) it locked onto 8 satellites in less than a minute in my bedroom agian.
I'm starting to like this phone again.
EDIT AGAIN...Spoke too soon... It's doing it again. It was fast for 2 locks and 2 soft-resets but now it's slow again.
This is what the SUPL AGPS key looks like in my registry:

Nope. I'm not using any type of TOA or AOA, or what you and the OP are describing as "AGPS" on this handset. Network provided AGPS is disabled. Furthermore, GPS performance is somewhat better when my GSM radio is off.
Note that I am using the artificial ephemeris information provided by the Q or "QuickGPS" as most users know it.
These shots were taken in my home office scenario I described above. PDoP is pretty high (but still good) as I am in a poor visibility scenario (lots of multipath, limited sky view, etc.)

Well... I finally got AGPS working for me(at least it feels like it). My GPS is now locking onto 6-10 satellites in less than a minute every single time. Even after a soft-reset without using any kind of primer like GPSToday or HTC GPS Tool.
I'm a happy camper.
All it took was a little tweaking to the registry and now it works.
I attached a cab file to fix the AGPS.

Harvey,
Are you downloading the QuickGPS file? If so, what's the age of the download?

Where does QuickGPS download to? I downloaded it today but I never bothered looking for the file it downloaded.

I would suspect you are still not using network-assisted positioning. The QuickGPS file is aiding the receiver.
If you were using network assistance you would be getting rough position (<1000m) in seconds. Even indoors or your basement where there is zero GPS signal available.

Here's a quick way to test if AGPS is really working.
Set GPSMode to 1. GPSMode is normally set to 2 - it will auto-fallback if AGPS fails.
GPSMode 1 will continually try to get an AGPS fix, and not send you any NMEA data at all if it doesn't. You'll probably need to up the value in TimeBetweenFixes from 1 to at least 3 or 4, allowing only 1 second between fixes doesn't give your phone enough time to send location data to the AGPS PDE server and get a response.
Anywho, in GPSMode 1 i get no NMEA strings at all, so my agps is definitely broke

You may be right but I feel that It's still using some form of network assisted GPS because it's never been this fast before. I hard-reset and did not use QuickGPS at all and my results are the same.

Try turning off your radio to see if you still have the same TTFF.

Remember QuickGPS will download it's data in the background on a cradled connection with no cue from you, too, so make sure it didnt download \Windows\xtra.bin and inject it without you knowing
Also the QuickGPS data survives a hard reset if "ClearGPS" flag isnt set for the hard reset program or you don't have the CleanGPSData package in your ROM.

I'll try this now.
EDIT:: Seems you're right. It just locked onto 10 satellites in flight mode right in my bedroom in less than 30 seconds. WOW. Never saw it do that before.

Good catch Da G.
Harvey - are you willing to do a little test?
To test if network assistance is available and helping you might want to try the following.
This test will need to be performed at the same location in an ideal, open-sky condition with the handset in the same orientation in your hand each time:
1. Make sure your handset is free of the QuickGPS file.
2. Shut off all radios, go outside in a clear, open-sky environment.
3. Acquire 3D position fixes 10 times. Record the times it takes to acquire in seconds (aka TTFF).
4. Average the TTFFs
5. Power Cycle the handset.
6. Ensure no programs or registry settings inhibit AGPS or network assistance.
7. Make sure there is no QuickGPS file present.
8. Turn on your GSM radio.
9. Re-acquire GPS 3D position fixes in the same open-sky area 10x and record each TTFF
10. Average the TTFFs
What's the result?

HTC's A-GPS Hoax

Remember the time before HTC launch HTC Diamond/Touch Pro? Everywhere in the news and also HTC's own website stated that the builtin GPS is an A-GPS. HTC even boost about it's A-GPS feature. If you have read the product specification for HTC Diamond, the GPS is stated as A-GPS.
Now, if you go to HTC's website, HTC has changed the specification from A-GPS to Internal GPS (for both Diamond and Touch Pro).
Of course we know that it is has the A-GPS feature, but it is not supported like Nokia (where it has its own server, supl.nokia.com for the A-GPS to connect to). HTC does not provide such feature for us. So before the product is released, tell everyone that it is offering A-GPS (which HTC won't support), then when it is released, quietly change the specification to Internal GPS.

It's a bit more complicated.
For the record, I really would like to point out that "AGPS" can stand for both Assisted and Aided GPS. Most people do not know there is a difference. I assume you might. However, I digress...
The HTC Raphael as well as almost every single handset designed, manufactured and sold world-wide is AGPS enabled. Luckily for us, most HTC devices go a step further and provide 'hybrid' GPS front-ends.
In the Raphael's case, the GPS RF front-end, GPSOne, is a part of the MSM platform and is a hybrid GPS engine which means it is capable of Aided (in this case 'QuickGPS'), Assisted (Network Aided) and fully Autonomous GPS. The Raphael is compliant with OMA SUPL and 3GPP location standards.
The people you should be complaining to is not HTC but rather your network operator who may or may not be allowing network location data available via the user plane.
The AGPS on the HTC Fuze I am using on North Americas' AT&T is working just fine.
Nokia happens to be VERY proactive about location information and have made it clear they wish to be at the forefront of this market enabler.

So? In strong consideration to the many laymen out there who have been falsely led to believe that A-GPS is 'inferior' to GPS then this may be dumbed-down BUT smart marketing by HTC. With the crap out of other companies and much misinformation found on the internet, too many people now falsely believe that A-GPS denotes an 'inferior' hardware device that ONLY derives location from that of the cellular system (triangulation from cell towers being the popular buzz) while lacking the hardware to derive a location from satellites....
We here should particularly know better that the HTC Qualcomm devices have the integrated GPSOne A-GPS chipset. That denotes an ability to derive the location, downloading of satellite ephemeris data, and possibility to refine location precision via GPS satellites and assistance or fallback to a Network Assistance server.

As it is practiced it's down to the responsibilities of the carriers to support their subscribed client with the Assisted mode from THEIR Network Assistance Servers.

Dude, I politely declare your topic to be conflated FUD.
move on...nothing to rant about here.

So is there any way we can tell our phone's to connect to Nokia's AGPS Server?
Don't get me wrong. Right now I'm pretty happy with my GPS since it locks faster than my Lowrance GPS in my car and it locks onto just as many satellites.
If I could cut the time down to several seconds instead of 30 seconds locks, I'd be even happier than I already am but I'm actually quite content since it's already very fast.

Harvey,
It would be almost impossible.
The SUPL middleware clients are different between the OS (Symbian vs WinMo) and are based on platform and handset.

I actually got it working with Da_G's help. It's very fast now. Maybe 10 seconds or less every time even without extra.bin from QuickGPS.

a-gps works for me

a-gps is good for those times when you drive through a tunnel and the gps is cut off for a mile or two, your phone has a chance to redeem its lack of satellite reception by giving a +/- 2000 feet estimate as to where you are.
It would be better though to use the phones accelerometer to create a cheap "inertial navigation system" (a handy backup system used in airplanes) by using last known location before GPS fails + detected movements by accelerometer to determine current location. This would be far more accurate than triangulation. Though unless I am missing something, the software simply isnt there and would take a lot of work to develop

Hmm, I think at the least you would need to strap your phone to the vehicle to ensure it stays at the same angle, etc. while moving.. and then it would become wildly inaccurate the moment you turned off course a little.. without a gyroscope or compass.. doh! but i like that idea

Interesting topic here, wish I could join in an intelligent manner but alas, my gps refuses to connect to anything, let alone satellites. My point is this, I've done extensive searches to try and get the thing to actually work say nothing about working in a stable way and every one of the suggestions whether it be registry hacks, advance config tweaks or programs suggested to shut off agps because it only hindered and really didnt work. What's that about? The bottom line is the gps on these phone's collectively if compared to the iphone or any other comparable device is deplorable period. My wife has an iphone and the gps works flawlessly. My friend has the touch pro for sprint and it works flawlessly. What is going on?

sorry not really on topic, just a bit frustrated. I am curious why everyone seems to think it needs to be turned off though...

Im on AT&T too in North america and my GPS takes a good 5 minutes to find satalites, are you using stock radio and rom or did you change the radio?

ATT Northamerica here as well. I've tried nearly every radio, every rom and none of them have been good experiences although... I did manage to get it working somewhat a few ROM updates ago. Don't remember how I did it though because it was before I realized it was going to be a huge issue for me.
I don't think it matters what radio your using quite honestly. Nor do I think it matters what drivers your using or ROM your using... I think it has something to do with the hardware or the implementation of the chip through either all of the above or specific gps programs.
I could be wrong...actually I probably am wrong. All I know is I've owned several Fuze's which I returned for various reasons and all of them were terrible experiences with GPS.
If you look at the proposed solutions here on the forum's they range from simple to far fetched to just plain ridiculous. Most of them are just explanations of what happened to work for the person posting and most of the posters aren't even sure what they did.
Sounds like a hardware/foundation level driver issue to me.

does that agps using at&t's networks work with tomtom if so which version do i need. thanks

This much is true, however with a little thought we could probably convince the system to "trust" that we are still on the road, and limit the accelerometer's influence on the foreward / backward motion (the accelerometer could be set to only interpret change on one axis). You are right, the traditional inertial navigation system requires gyros and a compass, vaccuum pump driven, but in a vehicle on the ground we have far less variables. The system wouldn't be perfect, but it would be a lot better that the current system, which is crude triangulation

ya the gps on the touch pro/fuze is complete BS. there is definately something wrong with the agps. Whenever i had agps enabled it would either not connect at all or connect and then quickly loose satellite reception. when i disabled agps, it would get a lock after 2-3 mins minimum and then be fine. I had agps in my tytn II, nokia e71, and now my touch HD, and they all work fine. i just got the touch HD, and with agps enabled i can get a lock from a cold start in ~30 secs. plus this huge screen makes navigating a pleasure

i do have a question to ask everybody that might help this problem. when you click on tomtom after not using it for a day or two (as in cold start). from the tomtom home screen.... click on the signal bars in the lower right hand corner then click on the signal bars in the upper right part of the screen. does it show little balls with numbers in side them or not?
also what version is everyone using?

An absolutely innane comment in light of others having it working and a previous statement in this thread concerning the Touch Pro working "flawlessly." Dude, don't post in a bubble and make the classic error of an absolute write-off when your particular item is failing. It is not all or nothing.
Mine works. Mine consistently works "flawlessly" and that is witnessing a data connection made each fairly fresh time the GPS is initiated and then followed by satellite reception within seconds to location deriving locks within 10-20 seconds. The Assisted portion of the A-GPS is functioning and assisting the GPS attain quicker satellite locks with updated ephemeris data from my designated Network Assistance server.
For those who have Raphael's where the internal GPS is unable to receive locks -- then first blame your carrier (who in North America are typically ultimately responsible to the software setups on their phones often to help push their own pay-per-use GPS software) and then secondly place some fault upon yourself for not finding the existing resolutions to work around the carrier implemented GPS limitations. The latter is understandable as there is plenty of misinformation around and posted solutions that are quite dated --> old guesses at a necessity to disable the Assisted modes....
By tobeychris on ppcgeeks, here are the working AGPS solutions for some North American CDMA carriers. Carrier specific CABs are listed. Similar resolutions exist for GSM Raphaels.

My experiences
I have lots of trouble with the GPS on a stock rom ATT Fuze. When I turn off a-gps and quick gps, then enable the windows mobile intermediate driver (the external GPS settings icon) with hardware on com4: baud 4800 and soft-port com6: and use 4800 baud EVERYWHERE I can, It usually works. With any other setting (mostly when a-gps enabled tho) it connects for 2 seconds then sets the hardware port to "(none)" in the windows mobile GPS settings and refuses (haha fuses) to do anything with the GPS again until I reboot. I would like to know exactly what the $%^*%$^ is going on.

As previously mentioned it is likely your carrier's fault for not adding an Assistance Server IP address to permit the assisted portion of the A-GPS chipset to properly function. That is why you can better attain a satellite lock when the Assisted mode is disabled but fail when the hardware first expects to download the latest ephemeris data from its non-existant Network Assistance server - 0.0.0.0 as the IP address or lack of carrier info thanks to AT&T).
Blame AT&T for 'crippling' (not fully implementing) the GPS features of your phone. Resolve your lack of an Assisted Server IP issue with searches and previously posted links.
