Rtcm Response Message Commands - ashtech GG Surveyor Reference Manual

RTCM Response Message Commands

The RTCM commands allow you to control and monitor RTCM real-time differential
operations. The RTCM commands are only available if the differential options are
installed in the receiver. If the Base Station option (B) is installed, then only the base
parameters and general parameters commands are accessible. If the Remote option
(U) is installed, then only the remote parameter and general parameter commands are
available. For a more detailed discussion of RTCM differential, refer to Chapter 5,
Differential and RTK Operations.
Set Commands
All RTCM commands but one are set commands. Through the set commands you can
modify and enable a variety of differential parameters. Certain set commands are
applicable only to the base station and certain commands only apply to the remote
station. If the set command is sent correctly, the receiver will respond with the
$PASHS,ACK acknowledgment. If a parameter is out of range or the syntax is
incorrect, then the receiver will respond with a $PASHS,NAK to indicate that the
command was not accepted.
Query Commands
There is only one query command: $PASHQ,RTC. Use this command to monitor the
parameters and status of RTCM differential operations. The query command has an
optional port field. If the query is sent with the port field left empty, then the response
will be sent to the current port. If the port field contains a valid port (A-C), then the
response will be output to that port. For example, the query:
Will output an RTCM status message to the current port. The command:
Will output an RTCM status message to port C.
