Differential Commands
USE: SBAS Satellites for Acquisition
$PASHS,USE,SBA,c1
This command includes or excludes all SBAS satellites simultaneously, where c1
is Y (include) or N (exclude). In a case where several satellites were excluded from
being tracked with the
$PASHS,USE command, this shortcut command once again
includes all SBAS satellites for tracking.
To enable or disable the tracking of all GPS satellites, use the
$PASHS,USE
command. See USE: Satellites for Acquisition , on page 178 for a description of
this command.
This command does not change the current GPS/SBAS configuration.
USP: SBAS Satellites Used in Position Computation
$PASHS,USP,SBA,s1
This command includes or excludes all SBAS satellites used in the position
computation, where s1 is YES to included all or NO to exclude all. In a case where
several satellites were excluded from the position computation with the
$PASHS,USP command, this shortcut command once again includes all SBAS
satellites in the position computation.
To enable or disable using all GPS satellites in the position computation, use the
$PASHS,USP command. See USP: Satellites Used in Position Computation ,
on page 179 for a description of this command.
If the receiver is set to single mode, the DG16 uses only the range information from
Channel 1 in the navigation solution. If the receiver is set to dual mode, the DG16
uses the range information from both channels depending on the
$PASHS,SBA,CDU setting.
The SBAS ranging information is available in both the MCA and MBN formatted
messages so that the SBAS satellite can be used seamlessly in a navigation
solution.
You must use the $PASHS,SAV command to save the parameters set in this command to memory.
DEFAULT SETTING
USP,SBA— NO (exclude all)
