Pdp: Pdop Mask Value - ashtech DG16 Reference Manual

PDP: PDOP Mask Value

$PASHS,PDP,d1
This command sets the value of the PDOP (Position Dilution of Precision) mask,
where d1 is a number between 0 and 99. The receiver stops computing positions
when the calculated PDOP value exceeds the PDOP mask value. You can view
the current PDOP mask setting by entering the $PASHQ,PAR command and
checking the PDP field.
Example
Enter the following command to set the PDOP mask to 30:
$PASHS,PDP,30
PEM: Position Elevation Mask Value
$PASHS,PEM,d1
This command sets elevation mask for position computation, where d1 is 0 to 90
degrees. Default is 5 degrees. A GPS or SBAS satellite with an elevation less than
the elevation mask setting is excluded from position computations. You can view
the current elevation mask value by entering the query command $PASHQ,PAR
and checking the PEM field.
Example
Enter the following command to set the elevation mask to 15 degrees:
$PASHS,PEM,15
PHE: Photogrammetry Edge Mode
$PASHS,PHE,c1
This command synchronizes the photogrammetry trigger to the rising edge or the
falling edge of the timing pulse, where c1 is either R (rising edge) or F (falling edge).
Default is R.
