11.2 Downloading Satellite Data via QuickGPS
Before you start using 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. As time passes,
the remaining days and hours of validity will
be shown.
To speed up GPS positioning, download the
latest ephemeris data when the validity of the
data expires.
