PEM: Position Elevation Mask
$PASHS,PEM,d
This command sets the elevation mask for position computation. The structure is
$PASHS,PEM,d where d is 0 to 90 degrees. Default is 5 degrees. Satellites with
elevation less than the elevation mask are not used for position computation.
Example: Set position elevation mask to 15 degrees
$PASHS,PEM,15<Enter>
ELM controls the elevation angle for satellites used for raw measurement output and Base station
output of RTCM messages Type 18 & 19. PEM controls the elevation angle for satellites used for
positions and Base station output of RTCM messages Type 1, 9, 31 & 34.
PHE: Photogrammetry Edge
$PASHS,PHE,c
This command allows you to set the edge (rising or falling) at which the trigger signal
associated with the photogrammetry event will be measured where c = R (photo rising
edge), or F (photo falling edge). Default is R.
Example: Set the photogrammetry edge to falling edge.
$PASHS,PHE,F<Enter>
$PASHQ,PHE,c
The associated query command is $PASHQ,PHE,c, where c is the optional output
port.
Example: Query the photogrammetry edge setting to port B.
$PASHQ,PHE,B<Enter>
$PASHR,PHE,c
The response is in the form:
$PASHR,PHE,x*cc
where c is R for rising edge, or F for falling edge, and *cc is the checksum.
