RTCM interface
The AUX port(normally not used) on the R4 Transponder handles
input of differential corrections in the RTCM format. When this
port is configured for RTCM input (default) it accepts the
following RTCM messages:
!
Message type 1 – Differential GPS Corrections Fixed
!
Message type 2 – Delta Differential GPS Corrections Fixed
!
Message type 9 – Partial Satellite Set Differential GPS
Corrections Fixed
These messages are the ones used in the Radio Beacon Long Wave
systems operated by coastguards and lighthouse authorities
throughout the world. For the definition and data encoding of these
messages see Ref. [4].
