A-GPS
The Global Positioning System (GPS) is a Global
Navigation Satellite System. It uses satellites that transmit
precise microwave signals, which enable GPS receivers
to determine their current location and time.
When an user accesses an application that requires GPS,
then GPS is turned on automatically. After the application
is closed, GPS is turned off automatically.
The GPS relies on satellite signal to calculate position.
Under conditions of poor satellite reception (that is,
under a tree, bad weather, and so on) standalone GPS
receivers take long time (sometimes a few minutes) to
provide location information to the users. The special
feature Assisted GPS (A-GPS) available in Sonim XP5300
FORCE 3G speeds up the phone’s process of calculating
the position irrespective of the signal conditions. When
A-GPS is enabled, the phone automatically downloads
the latest satellite related information (Ephemeris data)
through GPRS. This information is used along with the
satellite signals to calculate the position (Downloading of
Ephemeris data may result in network charges).
To congure the A-GPS on your phone, do the following:
1. Procure the internet access point and A-GPS server
information from the service provider or operator.
2. Select Menu > Settings > AGPS settings.
3. Select AGPS > On.
4. Select AGPS proles and then press Select. In
AGPS proles, select the required prole and click
Options > Activate. You can also select Edit. Enter
the name, address, data account, port, and TLS as
provided by the service provider or operator.
