208 Using GPS

13.2 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, Wi-Fi, 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.
