LD6 Operation
COM4 – LBAND RTCMb Output – User applications
The LBAND - RTCMb output is typically used to provide corrections to users' equipment.
This enables the user to enable/disable reference stations as required by his equipment
without adversely affecting the internal solutions. It may be necessary to make changes
to the transmission protocol if long cable runs are required.
COM5 – GNSS NMEA ZDA Message, direct from GNSS Receiver
The GNSS – NMEA output is only used to provide NMEA ZDA time stamp data for use in
conjunction with the 1pps pulse. The message is taken directly from the GNSS receiver to
ensure the best possible synchronisation with the 1PPS.signal
No changes should be made to the configuration of the GNSS receiver without first
consulting VERIPOS.
COM6 – MF RTCM Output
The MF – RTCM output provides RTCM correction data from the MF station.
It is mainly intended for use by Verify QC as a backup when all other correction sources
have failed or been disabled.
COM7 – UHF RTCM Output
The UHF – RTCM output provides RTCM data from the UHF station when in use.
The corrections may be output to be used by Verify QC or third party equipment.
(This option is designed to support the Petrobras UHF chain in Brazil. Users considering
other applications should consult the VERIPOS Helpdesk for advice.)
Further details for all ports are given in Section 4.
