Utilizing Integrity Information - ashtech DG16 Reference Manual

SBAS corrections. These messages help determine and report the quality of
the corrections/solution, but do not to allow or disallow position computation.
Use the $PASHS,SBA,PAR,OFF command if you do not want a differential
position output without the whole of correction set of fast, slow, and iono
components. The default is ON: partial corrections are allowed.
After a cold start, the first solution is corrected with all components but the
ionosphere and subsequent position fixes are corrected with all components.
The number of SBAS channels used for the utilization of SBAS corrections depends on the
$PASHS,SBA,CDU setting.

Utilizing Integrity Information

You can use the $PASHS,SBA,INT,ON/OFF command to enable or disable
the integrity information available. The default is ON.
The number of SBAS channels used as a source of integrity information depends on the
$PASHS,SBA,CDU setting.
Ranging signal utilization in navigation solution
This function will be available to the user by means of $PASHS,USP,SBA,Y/N
command. Default is Y.
SBAS ranging information shall be available in BOTH MCA and MBN format
so the SBAS satellite can be used seamlessly in the navigation solution by
raw data users.
The number of SBAS channels used for ranging information depends on the $PASHS,SBA,CDU
setting.
Saving SBAS Settings
You can save any SBAS parameters you set using the $PASHS,SAV,Y
command.
The DG16 two-channel scanning beacon receiver has two modes of
operation: automatic or fixed. In both modes, the beacon receiver can provide
corrections from one or two beacon stations.
The DG16 beacon receiver outputs in RTCM SC-104 differential correction
format.
