Enhancing Gps Performance - Motorola MTM800 FuG Feature User Manual

Feature User Guide
Location reports are sent in TMO and can also be provisioned to be sent in DMO. If the radio is provisioned to
provide user indications, the feature operational status is indicated on the radio display.
Depending on the radio configuration, viewing the radio position and the status of the visible satellites is available.
The position may consist of longitude and latitude, UK, or Irish grid coordinates. The GPS Location Service feature
can be enabled or disabled as a whole using the CPS. It is possible to configure the feature parameters using the
CPS, or over the air. The CPS configuration provides a default profile. The commands received over the air may
overwrite the default profile configuration. The profile assigned to the radio determines when to send location data,
what data to send with what accuracy and to what address. All data requests and configuration commands received
over the air are checked to confirm they have come from a trusted source. Location reports are accepted only from
authorized ISSIs or IPs, depending on the configured transport layer (SDS, Packet Data).
Ensure the application receiving location messages and the radio are configured in a corresponding way.
Otherwise the radio will reject all system GPS requests.
This is a selling feature.

4.1 Enhancing GPS Performance

Sometimes the GPS feature is unable to complete a location calculation successfully. You hear an audible tone
indicating that your radio cannot see the satellites.
The GPS feature works best where there is nothing between your radio and a large amount of open sky. To maximize
the ability of your radio to determine a location fix, avoid closed space, tall buildings, and foliage. If possible, do not
use GPS in underground parking lots, tunnels, under bridges, and close to high buildings.
