Assisted Gps; Poor Satellite Coverage - Benefon Track Pro Configuration Manual

CONFIGURING SETTINGS FOR THE BENEFON TRACK PRO

Assisted GPS

The phone has capability to receive assistance to the
GPS receiver in order to speed up the initial position
calculation. This is very useful feature if the phone is
in poor satellite coverage.
Assistance can be supplied over the Mobile Phone
Telematics Protocol in a binary coded protocol mes-
sage. The message will contain ephemeric and alma-
nac data which is based on a rough position calculated
by e.g. GSM network parameters (Cell-ID, CI-TA etc).
The assisted GPS is supplied from a third party station
server.
Using the AGPS does NOT affect the accuracy of the
position. If the last position fix is deemed to be too
old, and the AGPS is set, the AGPS feature is automat-
ically used to speed up the position determination.
The cost of the AGPS service is determined on the
contract of the service provider.
You can specify settings for ordering assisted GPS in-
formation from a service provider.
• Number of satellites: Select the number of satellites
(5a). However, note
selected, the faster the service but the higher the
charge.
• SMS number: Key in the SMS number of the AGPS
service (5b).

Poor satellite coverage

Notify service center when satellite coverage
phone may notify the service center if the satellites
are suddenly dropped and position is lost, e.g. when
entering in a building.
When the phone loses the satellites, it will send only
one notification, despite of how long a time it stays in
the poor satellite coverage.
Key in the timeout in minutes (6). Note that this op-
tion will be activated only after the phone gets the
first position after this configuration.
The timeout indicates, for how long the phone is al-
lowed to stay in a poor satellite coverage before send-
ing a protocol message to the service center - the
smaller the number you set in here, the faster the
phone will react to lost satellites and the sooner the
notification will be sent.
