maintenance of the system. Any changes that the Department makes may
affect the accuracy and function of the GPS system.
10.3 Downloading Location Data via QuickGPS
Before using the device for GPS navigation, open QuickGPS to download
ephemeris data (current satellite position and timing information). QuickGPS
significantly speeds up the time for determining your GPS position. QuickGPS
downloads ephemeris data from web servers, instead of from satellites, using your
device’s Internet connection via Wi-Fi, ActiveSync or GPRS/G.
To open QuickGPS
Tap Start > All Programs > QuickGPS.
To download GPS 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.
