figuration.

Configure the settings as required:
Enable A-GPS Client
The feature Enable A-GPS Client will schedule assistance data to be collected and updated
every hour. On startup, if data is present, it will be sent to the receiver.
Apply A-GPS Data
When this option is selected, SecureSync will immediately apply the time, position and satellite
data to the receiver once you click Submit.
Time and position are user-configurable; SecureSync collects A-GPS satellite data from an
external source automatically.
Note: Once you click Submit, any parameters entered under Apply A-GPS Data
will override the system Time and Position data. Exercise caution when using this
feature, since this could negatively impact the GNSS receiver operation.
