A-GPS serverDemo/Test applicationEnvironment
GPS Server
I The GPS server aids the mobile with calculating the positionI Advantages: Saves time and battery power
I Tasks:I Receives approximate position from location serverI Fetch latest info on satellite positions etc from internetI Pick satellites closest to the approximate positionI if MS-Based → Forward assistance data to mobile and let the
mobile calculate the positionI if MS-Assisted → Calculate the position
I Help from Geodesy department at KTH with algorithmsI Will provide a report with the necessary info
I Location Server implemented in ErlangI Mobile Arts will provide an Erlang API
