Comment The code allotted to a position solution of the SBAS
differential type is either “2” or “9”, depending on the last
$PASHS,NPT command run.
Automatic Output
of GGA Messages
This is a reminder on how to output GGA messages at regular
intervals of time: Use the $PASHS,NME command with the
syntax below:
$PASHS,NME,GGA,,ON,
For more details on the $PASHS,NME command, refer to the
Set Command Library Chapter.
