10.2 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 Wi-Fi, ActiveSync or data connection. 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.
Download options
To configure download times, tap Menu > Options and choose from the available options:
Remind me when data expires. Enables your device to display a reminder message when the validity
of the ephemeris data has expired. When you see the reminder message, tap Menu to dismiss the
reminder or to set the snooze time so that you will be reminded again. Tap OK to open the QuickGPS
program and download the latest data.
Autodownload when data expires. Allows ephemeris data to be automatically updated onto your
device when the data has expired.
Autodownload when connected to PC via ActiveSync.
Allows ephemeris data to be automatically downloaded via ActiveSync to your device when your
device is connected to your computer. Your computer must be connected to the Internet in order to
download data.
Note The ephemeris data is stored on HTC Web servers. QuickGPS is preconfigured to connect to these servers.
