Chapter 5: Features
The Global Navigation Satellite System (GNSS) Location Service feature uses information from GNSS
satellites orbiting the Earth to determine the approximate geographical location of your radio.
The GNSS Location Service availability, accuracy, and the position calculation time vary depending on
the environment in which you use the radio. The GNSS Location Service can assist your dispatcher or
colleagues in many ways. For example, deploying of resources more efficiently or locating your radio
when you trigger your emergency service.
The radio can display the location information directly on the screen or send it over the air to your
dispatcher to display it in the control center. Check your radio configuration details with your service
provider.
The radio supports the following system combinations:
• GPS
• GLONASS
• BeiDou
• GPS + GLONASS
• GPS + BeiDou
IMPORTANT:
Where the signals from satellites are not available, the GNSS Location Service does not work.
This usually happens when your radio cannot establish a view of a wide area of open sky. An
example would be when the GNSS antenna is covered or facing the ground. Such situations
include being:
• In underground locations
• Inside buildings, trains, or other covered vehicles
• Under any other metal or concrete roof or structure
• Near a powerful radio or television tower
• In extreme temperature outside the operating limits of your radio
Even if your location information can be calculated in such situations, it may take longer to do so.
Therefore, in any emergency situation, always report your location to your dispatcher. Where adequate
signals from multiple satellites are available, your GNSS Location Service feature provides a location,
most probably near to your actual location.
The radio can be triggered to send Location Reports in various circumstances, for example:
• Upon a request
• Entering Emergency Mode
• At specified time intervals
• At specified distance intervals
The Location Reports can be sent both in TMO and DMO by using:
• SDS messages
• Packet Data (in TMO mode only, with Packet Data enabled on the network by the service provider)
The radio can be configured to give audio-visual notifications upon sending the Location Reports.
Depending on the radio settings, 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.
