Differential Commands 311
Differential Commands
If you enable partial SBAS corrections, the DG16 will output a differential position
without the whole set of fast, slow, and ionospheric components.
If you want the entire set of fast, slow, and ionospheric components along with the
differential solution be sure that this command is set to OFF.
You must use the $PASHS,SAV command to save the parameters set in this command to memory.
RTC: SBAS to RTCM Interface
$PASHS,SBA,RTC,c1,d1,d2
This command sets the interface parameters for SBAS based RTCM messages.
Table 9.13 outlines the parameters for this command.
Message Type 3 contains the current GPS/DGPS position of the receiver (if in
Stand-alone or Remote mode).
Examples
Enter the following command to enable the SBAS based RTCM message 1 from
port A at 1Hz.
$PASHS,SBA,RTC,A,1,1
Enter the following command to disable the SBAS based RTCM message 1 on
port A.
$PASHS,SBA,RTC,A,1,0
Either one or two SBAS channels are used for the conversion, depending on the $PASHS,SBA,CDU
setting. The save current SBAS to RTCM conversion settings to the battery back-up memory, issue
the $PASHS,SAV command.
