9.3 Downloading Satellite Data via QuickGPS
Before you start using your phone for GPS navigation, open the QuickGPS program
first to download ephemeris data (current satellite position and timing information)
onto your phone. 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 phone, which can be via Wi-Fi,
ActiveSync or GPRS/3G. This significantly speeds up the time for determining your
GPS position.
To open QuickGPS
Click Start > All Programs > Accessories > QuickGPS.
To download data
Click 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.
