Output Message Library
• Most of the fields found in the DPC and DBEN data
outputs are similar.
• DPC will not be generated if the [K] option (RTK Base) is
missing.
• DPC data are affected by the last $PASHS,UTS command
run. By default, this command is set to “ON”.
• DPC data are affected by the last $PASHS,ANP,OUT
command run.
• DPC data can be made available on several ports
simultaneously.
• DPC data can be output at a rate of up to 20 Hz, but the
throughput compared to RTCM-3, CMR and ATOM may be
quite higher.
• DPC pseudo-ranges are smoothed by L1 & L2 carriers.
• L2 data are always L2P(Y) data (RINEX code W). To output
complete DPC data, the receiver must be configured
accordingly (see $PASHS,GPS).
