SAT: Satellite Status
$PASHS,NME,SAT,c,s
This command enables/disables the satellite status message to port c, where c is A, B,
C, or D, and s is ON or OFF.
Example: Enable SAT message on port B
$PASHS,NME,SAT,B,ON <enter>
$PASHQ,SAT,c
Query satellite status where c is the optional output serial port.
Example: Send SAT message to port D
$PASHQ,SAT,D <enter>
$PASHR,SAT
The response message is in the form:
$PASHR,SAT,d1,n(d2,d3,d4,f5,c)*cc <enter>
where n = the number of SVs tracked.
The elevation/azimuth prior to the first computed position may be erroneous if the last position
stored in battery back memory is very far from the current point.
Example:
Query: $PASHQ,SAT <enter>
Response:
$PASHR,SAT,04,03,103,56,50.5,U,23,225,61,52.4,U,16,045,02,51.4,U,
04,160,46,53.6,U*6E <enter>
