8 NXDN CONVENTIONAL SYSTEM
8.16 Receiving GPS Data
8.16 Receiving GPS Data
The base station receiving GPS data from the transceiver of a mobile station can send the GPS data to the PC as serial
commands. If a PC installed with a mapping application is connected to the communication port of the base station
transceiver, the location information of mobile station transceivers appears on a map on the PC display. This function is
convenient for dispatch control or a traffic control system.
Also, if a mobile station transceiver connecting to a GPS receiver unit receives location information (GPS data) from a
GPS satellite, the current location information of the own transceiver can be displayed on the LCD.
Note
• If the optional VGS-1 unit is installed in the transceiver, the GPS data acquired from the GPS satellite can be stored at certain intervals
in the VGS-1 Unit. (Refer to
• For a transceiver receiving GPS data, "Data+GPS Data Output" must be assigned to the communication port connected to a PC
installed with the mapping application. (Refer to

Whether to send data to the mapping application when the base station transceiver receives the GPS data from the mobile
station transceiver can be configured.
Following are the type of data that can be sent to the mapping application.
Data
Upon receipt of the GPS data, the transceiver at the base station extracts the $GPGGA data in the NMEA-
$GPGGA (NMEA)
183 format from the received GPS data and sends the extracted data from the communication port.
Upon receipt of the GPS data, the transceiver at the base station extracts the $GPGLL data in the NMEA-
$GPGLL (NMEA)
183 format from the received GPS data and sends the extracted data from the communication port.
Upon receipt of the GPS data, the transceiver at the base station extracts the $GPRMC data in the NMEA-
$GPRMC (NMEA)
183 format from the received GPS data and sends the extracted data from the communication port.
Upon receipt of the GPS data, the transceiver at the base station creates the $PKNDS data which is the
Kenwood proprietary sentence from the received GPS data and sends the created data from the
$PKNDS (KW)
communication port. The $PKNDS data contains the $GPRMC data in the NMEA-0183 format, Unit ID, and
the status information.
Upon receipt of the GPS data, the transceiver at the base station creates the $PKNID data which is the
Kenwood proprietary sentence from the received GPS data and sends the created data from the
communication port. The transceiver at the base station extracts only Unit ID and the status information from
the received GPS data and sends the extracted data from the communication port of the repeater. This
$PKNID (KW)
sentence is recommended to be used along with $GPGGA (NMEA), $GPGLL (NMEA) or $GPRMC (NMEA).
For example, if $GPGGA (NMEA) and $PKNID are used simultaneously, the transceiver at the base station
sends from the communication port of the repeater the $GPGGA data in addition to the Unit ID and the
status information extracted from the GPS data.
Upon receipt of the GPS data, the transceiver at the base station creates the $PKNSH data which is the
Kenwood proprietary sentence from the received GPS data and sends the created data from the
$PKNSH (KW)
communication port. The $PKNSH data contains the $GPGLL data in the NMEA-0183 format and the Unit
ID. In order to send GPS data in Emergency Mode or by pressing the PTT switch, this sentence is used.
