Option
DGPS-System
The transfer of the GPS data (NMEA / RTCM) will be performed via telecommand- and telemetry data transfer via the UHF radio modem.
The RTCM data will be supplied directly by means of the DGPS receiver and transmitted to the GPS receiver.
The data of the position (NMEA) will be calculated with the correction data (RTCM) and transmitted via radio to the groundstation and the PC. For interpretation of the GPS measurement the FUGAWI software will be used.
The electronic map displays the actual position of the remote handling system on the PC monitor.
