11.2  Downloading Satellite Data via QuickGPS

Before you start to use your device for GPS navigation, open the QuickGPS program first to download Ephemeris data (current satellite position and timing information) onto your device. This data is needed to determine the GPS position of your current location.

QuickGPS downloads Ephemeris data from a Web server, instead of from the satellites, using the Internet connection on your device, which can be via ActiveSync or GPRS. This significantly speeds up the time for determining your GPS position.

To open QuickGPS

Tap Start > Programs > QuickGPS.

To download data

Tap Download on the QuickGPS screen.

On the screen, initially, you will see the Valid time of the downloaded data to be 3 days. As days and time pass, the remaining days and time of validity will be shown.

To speed up GPS positioning, download the latest Ephemeris data when the validity of the data expires.
