2.3.2 GPS
DMR supports GPS technology. The GPS feature is mainly used to check the radio’s
position and send GPS short message. You can send GPS message to inform the
control station or other radios the geographic position you are at. The feature is
only available for radios with the GPS modular.
GPS Setting
To apply the GPS feature, you need to enable it via the CPS. You can also set the
time zone, GPS speed unit and its update time on actual requirements.
After the feature is enabled, the radio will automatically search for the satellite and
update the GPS data until the feature is disabled.
GPS Message
GPS message is sent in DMR text message.
GPS Revert Channel
The GPS revert channel is used for GPS data report. After the radio makes
successful RRS registration, the control station can require the radio to report its
geographic position information according to the LP service agreement. And the
radio will report its position information to the control station regularly. During the
GPS data report, if the channel is occupied for other use, the radio will revert to the
preset channel to send the GPS message.
You need to set the “GPS Revert Channel” parameter via the CPS prior to use this
channel. When setting, you will need to consider the following notes:
