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).
