COM4 – L-Band RTCMb Output – VERIPOS Corrections
The L-Band - RTCMb output is typically used to provide corrections to users' equipment.
All available reference stations are enabled by default however the user can enable/disable
only the reference station(s) required if necessary. Unlike RTCMa, RTCMb is not used
internally by the LD6 therefore disabling stations on RTCMb do not affect any NMEA
position outputs from the LD6.
COM5 – MF RTCM Output
The MF – RTCM output provides RTCM correction data from the MF (IALA) reference
station currently in use.
MF corrections are generally only used as a backup when VERIPOS corrections are
unavailable or disabled.
COM6 – UHF RTCM Output
The UHF – RTCM output provides RTCM data from the UHF station when in use. The
addition of UHF corrections has primarily been 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.
