PDP: PDOP Mask
$PASHS,PDP,d
Set the value of the PDOP mask to d, where d is a number between 0 and 99. Position
is not computed if the PDOP exceeds the PDOP mask. The default is 40.
Example: Set PDOP mask to 20
$PASHS,PDP,20 <enter>
PEM: Position Elevation Mask
$PASHS,PEM,d
Set elevation mask for position computation where d is 0 to 90 degrees. Default is 10
degrees. Satellites with elevation less than the elevation mask will not be used for
position computation.
Example: Set position elevation mask to 15 degrees
$PASHS,PEM,15 <enter>
