A-GPS on trinity ?

Hi !
I've tried a search on this forum but "no result for this search"
So is there a A-GPS functionnality and how can I use it ? with which soft ?
Thx for your answers (and sorry if it has already answered before )

No AGPS for this Qualcomm GPS.
Beware of placebo effect of avaricum QGPS that some guys are using

A-GPS is supported within the chipset, but there is not yet any software which can access it, and no-one appears to be developing any.

It is not true!
Qualcomm MSM6275 Chipset is A-GPS

So, no AGPS for this moment...
you're right, wait

To be honest, I don't quite think GpsOneXtra Assistance will really come to trinity.
The press release is even much later than its release, and probably even though the chipset supports it, there's still a need for OEM to support it either in the driver or the OS level.
To date, even Kaiser don't support this. So don't hold your breath....

Erm - no A-GPS is present. It is something that is network operator dependent - so to say no AGPS for the moment is not strictly true.
GpsOneXtra Assistance is not the same as A-GPS. A-GPS means that the network operator must implement a dedicated server on their netowrks to manage this and it would not work with roaming.
GpsOneXtra Assistance uses an internet connection to connect to a non network operator dependent server on the internet to get information.
So, we don't necessarily have to wait for GpsOneXtra Assistance and there is, at the moment A-GPS on the Trinity - but perhaps not your network operator.

Yes, you are correct that A-GPS is present in Trinity - but seems that there are few operator (about 50) which actually supports the GPSOne platform in their stations.
See http://www.cdmatech.com/locationservicesshowcase/highlights.jsp
And before every operator supports this crap, I guess the best way to get a quick fix is to have a software solution to download the pre-made ephemeris data and almanac data to the GPS chipset.

Or just go outside for 3 minutes, and get a proper fix!
HTC do support the A-GPS on the P3300 with a dedicated server, but fix times are only a few seconds faster than with GPS alone in many circumstances.

Approximately from 15 seconds to 45 secs...

This is maybe a stupid question! but if my operator supports gpsone platform, then how does it work? is there a software to activate this?

AFAIK there is not yet any software to activate the GPSOne facilities on WM devices.

Something new today ?....
I think that Orange France support this...

...any news?

Still nothing new on this matter?
In finland a lot of people have Nokias phones wich uses AGPS, so I think that its wery well supported by the local operators. But I didnt understand from the messages that is there any software to download from anywhere? Or do we still have to wait? Does anyone know anything more about this matter now?

In Germany O2 sends a cell brodcast on channel 221 giving the coordinates of the next cellphone tower in Gauß-Küger-Notation format (Can be converted to WGS84 gps coordinates easily).
Allso google maps mobile can use a similar system to determine your position when not using GPS (the funny thing about that: people with gps buildin help google maps determine where the cellphone towers are located.)
Now somehow feeding these coordinates + downloaded almanach into the chip sould decrease TTFF + TTF sicnificantly.
But since nobody really knows the functions of the qualcomm chip/driver this is pretty far away from us right now.
My dream would be:
Since I will recieve a Cell Broadcast massage every time i change my cellphone tower a nifty little program will load the Position into the chip (or every time I turn on GPS it loads them in, since I don`t know if the chip can be accessed when GPS turned off [won´t bet on that])
besides of that the same application sould download updated almanach-data and allso load them in on gps startup.
But I think this will stay a dream

Assisted GPS Pharos?

The Pharos is supposed to have AGPS. Do they mean QuickGPS or is there really AGPS on it? Where can I find it on the Pharos?
I have the WM6.0 Dutch version.

when i turn on tomtom in my house it says im in the location of the nearest gsm beacon...before i have a satellite fix, thats assisted GPS i think...
quick gps only has the trajectories of satellites in the "local" sky so the gps chip can get a fix quicker

Strange, nothing happens when I start TomTom.
Can you give me your settings in the register:
HKLM>Software>HTC>SUPL AGPS>

i checked but no such key
wat is the setting of your key?

Keysetting in HKLM>Software>HTC>SUPL AGPS> is:
(Default) (value not set)
EnableAGPS 1
EnableGPSSmartMode 1
GPSMode 2
NumberFixes 389AC9FF
QosAccuracy 32 (50)
QosPerformance 59 (89)
ServerIP 195.207.101.126
Serverport 1E6C (7788)
TimeBetweenFixes 1
When I first started with the Pharos there was no AGPS, also not in the registry the Supl AGPS. I found a registry-entry for the Pharos on this site and put it on the Pharos. When I start 'Advanced Config' from Schaft I can see under GPS that AGPS is enabled.
When I start TomTom 7.9 there's no start of GPRS. Also my GPRS monitor sees no action. So I presume AGPS is not working.
Maybe I need some dll drivers, I don't know. Can somebody help?

you have a confusing story
first you talk about GPS and then about GPRS
these are 2 different things
GPRS is your data connection (in case EDGE is not available)
GPS is global positioning system and i didnt know tomtom 7.9 was out, i use 6.
if you do a simple search on the phorum you can see that tomtom 7.9 causes a few problems i suugest you read that!
my advice would be to revert back to 6 .. works great on the pharos

Maybe I'm confused. I thought Assited-GPS uses GPRS to make contact with the gsm beacons and so make a faster fix with these beacons. Am I wrong about that?
The builtin GPS from the Pharos works fine but is not very fast with the first fix. I thought AGPS would help making a faster fix.
I already had TomTom 7.4 and know 7.9 (cracked version). Works fine on the Pharos. I will look for the problems with 7.9 on the forum.
Thanks

hmmm yeah makes sense we do need a server to relay the info... but ive looked it up
http://en.wikipedia.org/wiki/AGPS
http://en.wikipedia.org/wiki/List_of_devices_with_Assisted_GPS
our device is on the list... but i dont think i have a server setting... and my gps (tomtom) doesnt have to have a connection to the internet.
strange but fun to find out how it works...

TomTom does not use the AGPS function. Enable quickgps to do this before you use your navigation software (TomTom). It can automatically download the satellite info for you which is good for about 2 days. You can update through your cellular connection if you have data on your plan or through activesync. TomTom 7 will work without using the AGPS function but it will take longer to find a fix on the satellites. TomTom 7 is required if you want to use the internal gps receiver with TomTom. TomTom 6 does not work without some hacks.

I think that Google Maps do use the AGPS function. It is much faster to find the coordinates than fx TomTom and other GPS software i've tried, so i think that a program needs to be developed with use of the agps function if it uses it..

the fast "fix" that you see with google maps it's not a gps fix... it shows you the cell radio where you are hooked

GPS X9601

GPS problems
Ok so I have a North American GSM x9501...
Never used the GPS (Telenav isn't available to Canadian residense). This device is unlocked and NOT purchased from Rogers...
Downloaded Google maps, tried to use GPS and it wouldn't work. Set the settings manually Com4 57600 baud... It says searching for satalites, and has some HUGE number (54357734578) in brackets... GPS doesn't work.
Installed the HTC GPS tool, looks like GPS data is coming in, but can't get a fix. Then tried to use GPSgate, and it says GPS data is coming in but cannot get fix. Both of these two apps can't find any satalites.
Does anyone know what is up?

yep, go out in middle of a field or open Terrace or any place where you can see the sky above you head directly and then start google maps with GPS or HTC GPS tool or GPS gate etc , wait 3-5 min and then it should have fix...
cheers

I've given is some time... Probably over 5 minutes...
It's just odd, I have lots of experiencing using GPS software and devices. It looks like it should be working, the only odd behaviour is:
1) It finds no satalites
and
2) Google Maps says "Seeking Satalites (3874732644)" which is odd, because theres not that many GPS satalites, lol.

Change the Baud Rate to 9600 and see whether it will work.

Tried different baud rates.
Yesterday I let it sit for 15 minutes on google maps until finally it said there was no reception...
And I know I have reception because I was outside. Both my TytN II and HP iPaq have no trouble aquiring fix's...

download free VISUALGPS CE and install. Then connect it to COM4 and press start.
See the NMEA log monitor section. You should see lot's of data, if not, your GPS might be bad.
I'm unsure if your 9501 will work with the ROM's we use in Europe to make calls, and have GPS enabled.. If it's OK, I would flash Thai Hugo's Age of Reason and check again your GPS.

I'm using the factory ROM for the X9501 (Which does support GPS off the bat).
I used the HTC tool, and it looked like NMEA data was going through...

On the HTC tool there is option to see the satellites , check if its has any satellites on red color, if so keep the shift out in terrace or garden until 3 satellite color changes to green , have patience....
if it does not show any satellite on the HTC tool then probably you need to flash the rom with some new rom from the forum ..
Before you do that make a copy of your Stock/original rom ..see forum for instruction
PS: Since you have the stock / orginal rom X9501....would you do me a favour and check if you connect to head set and on Windows mobile side WM6, can you record a message and then play back and you can hear your self back .... I wanted to know if the mic works with head set on WM6 side...for the Stock 9501 ROM.
Cheers.

Yes the Mic works, I helped Comonex with some testing to find out which radio firmwares supported the Mic.
Yes I can record/playback on the Windows Mobile side, and Yes skype works, etc....

Can I ask another favour , do you have any registry editor installed on you shift.
if so , can try to dump/export the registry settings for HKLocalMachine (HKLM) to a xml ot reg file and then copy / upload the xml/reg file here .
we want to use head set with X9500 shift and are trying to find a solution , may be its a reg setting that can fix the problem.
Appreciate your kind help

Nope , the issue is we cannot use the head set in WM6 as the mic on Head set does not work....so we have to use the speaker phone and its not good for phone calls private or business.
I would appreciate if you can help us to resolve the issue , if you can dump the reg keys for HKLM / Drivers/inbuilt ... it might give us some direction.
Appreciate your support.

blackstone is a real GPS ?

may be a dumb question.
Is blackstone has a GPS (not AGPS) ?
ie. without a sim phone card , it can still receive GPS signal for mapking ?

It's a real GPS, works great with, for example TomTom.

yes gps works without a sim card. agps is also available through registry settings but requires a Data connection.

lots of people seem to think that aGPS is a cheap substitute for normal gps
but thats not the case aGPS is normal gps plus the ability to get locations
from cellphone towers if one can't get a clear gps signal like if one enters
a long tunnel
http://en.wikipedia.org/wiki/GPS_Phone

aGPS is often mistaken as location-based service (LBS) or server-based GPS. mainly because the first generation of "Quick GPS" is also known as AGPS, which essentially is to download the satellite orbit path in advance instead of get it directly from the satellites at the point the receiver is trying to get a fix. The download process (receiving it from satellite) can be a lengthy process (30sec or longer depending on the reception level) thus the purpose of QGPS/AGPS.
I wrote a short article on the myth about AGPS, you can take a read if you are interested

Does anyone know what GPS chip is actually in the Touch HD? Is it a Sirf III? Is Static Navigation "ON" by default?

No, it isn't. GPS is integrated in the MSM chip, I think its called something like Qualcomm MSM7201A gpsOne.

Navigator demands data connection at start

Hi all,
firstly the software situation:
I have an HTC Touch Diamond2 wit a german Vodafone branding. Last week i installed the new official upgrade for german Vodafone devices - ROM version 2.16.162.1 HTC Touch Diamond2 (Voda_ DE).
With the old ROM and WM Version i didn't have this problem. Now - with every start of my TomTom Navigator after about 10 seconds a data connection is started. If there's wifi around - wifi, if not - mobile service. When i switch off the connection it stops and for some minutes - until i turn off the navigator it remains switched off. I haven't tested if during some time of the navigation it is turned on again.
In other discussions other users (with other navigation software) have also affirmed, that they also get an unwanted data connection.
Since then i have tried everything that i could think of. I looked over every setting in the TomTom software. Tried over TomTom Home. Tried reinstalling TomTom. Tried resetting to factory settings of TomTom. Nothing helped.
I then made a couple of hardresets of the device and i formatted the memory card also a couple of times. I then installed everything fresh - still demands data connection.
I then tracked the connections with a trafficmonitor software - one time wifi connection, one time mobile service ceonnection.
Looks like this:
WiFi:
system : 3.5 K
WZCSVC.dll : 1.2 K
mobile connection:
system: 1.2 K
WZCSVC.dll is Wireless Zero Configuration Service and i can at least understand why it is making traffic, since wifi is in use.
What is "system"?
Also - why more traffic for "system" with wifi than with mobile connection?
Yesterday i also tracked the connection and there was another .dll service which name i unluckily didn't mark. But it was gps*something*.dll.??
Could AGPS or Quick-GPS have something to do with this behaviour? Or the My Location service? I disabled and declined every setting that i could discover for those services, but i may have overlooked something?
Any ideas?
Please HELP!
Any suggestion would be appreciated!
Thanks in advance!

Problem solved (looks like it at least).
After installing HD Tweak and disabling A-GPS no data connection starts with starting the navigator.

Glad you solved your issue, but let me witness that in my case (i have A-GPS ON) when i use tomtom (7.916.9189) no data connection is going on. Anyway,just to be sure to keep your problem under control, i advice you to check also the weather update settings.

If you mean the two options which appear directly when the HTC Sence Weather Tab is opened - "update weather automatically" and "update with roaming" - i've checked them many times - they are off. If there is another setting where they can be adjusted i would appreciate it if you told me where and how. But i don't think this is it. Unless TomTom Weather is doing this.
But as i mentiones - there was a gps*something*.dll file, that caused the data transfer - that's why i thought it is something GPS related.
But I wouldn't mind to use another solution because now i think my gps signal is not that strong (at least in buildings).
Do you have 6.5 also? I don't think it could be a ROM thing?

As far as i could test it it makes the connection just once after starting the navigation. It doesn't keep pulling data the whole time. If it does it the whole time during a navigation - i don't know, haven't tested it.
But you can at least test it quickly before travelling - navigation on - status check. If something's moving - you have a problem.
There is one simple solution - you can either disable all automatic connection types - then you would't be able to surf the internet. In my case i didn't want to have to disable everything and/or to enable it by hand every time i use the navigator.
Or you can install HD Tweak and disable A-GPS. It's really very easy.

Without A-GPS enabled make sure you don't enter the wrong coffeeshop!!
By the way..Also TD2 Tools and Tom's Topaz Setting Tool can enable/disable A-GPS and are more specific for our devices...your choice...and have a nice trip

Hi,
have you tested HD Tweak? I'm just asking for comparison reasons. I used it just because someone said it worked.
If the other two are more suitable for the Topaz i would of course prefer them. Is there "a better one" comparing the two?
P.S. Following question just entered my mind. If i uninstall the other tweak software what happens with the changes i made with it. I mean i guess it changes values in the registry so that the settings are changed? I suppose everything will stay as the software "left" it before being uninstalled?

I use HDTweak to increase overall sound volume only. I had it installed for months in a previous config and I was quite happy with it, but the specific tweak apps look more friendly to me. I guess that if you uninstall hdtweak without restoring the default settings you will keep the tweaks applied..at your own risk
