A-Gps Question

---

I was just wondering what it is, as my orange rom had it before i unlocked and de-branded, is it usefull to me as my gps seems to be working fine without it. even when i had it it wroked better when it was disabled i think.

anyone know ?

Thanks

Would like to help.. but sorry, I do not quite understand your problem.

not so much a problem just wondering. il try and put it another way

before i debranded my orange branded jade, i had 2 options relating to gps, one was QuickGPS , thats still in the branded rom.
in the orange rom it had QuickGPS and another setting called A-GPS, just wondered what the second one was for as its not in the offical htc rom

As I have understood HTC pages :
"Quick GPS for Pocket PC from the HTC Corporation is included in the Windows Mobile 6 cusom build. Quick GPS can speed up the amount of time for determining a users GPS position by downloading the latest satellite information via an Internet Connection (such as GPRS, ActiveSync, etc). Quick GPS is intended for use in conjunction with Telenav but will provide the same experience if a customer is using another GPS Solution. "

And Wiki concerning A-GPS:
"An A-GPS system can address these problems in several ways, using an assistance server or other data from a network".

Quick GPS = A-GPS since both use the same principle i.e. downloading info about satellites via internet through GPRS, Wi-Fi if available etc.

i thought as much, those crazy orange people having two programs for the same thing lol thanks for clearing that up

I believe it's not equivalent.

For what I understand, Quick GPS uses general satellite tables, which are downloaded every week.

The a-gps is more precise : you download the satellite tables which are calculated for the BTS (radio antenna) you are connected to, so it is very precise. It's quite impressive: wherever I am, I am able to get a cold fix in 10 to 15 seconds..

Well it's what I have understood of the system....

i think you should start by creating a new thread in the right section

could be a problem with the radio rom or a hardware problem

never noticed this reply last time i checked , where is my head lol
that sounds about right, as a-gps never used the data connection and in my case (on o2-uk using a orange rom on a orange branded device) it would make sense that the a-gps data would of been avalible on the orange network and not on o2, and thats why i could not get a fix with it enabled

thanks for the precise answer gomifromparis
