RRE: Satellite Residual and Position Error Message
$PASHS,NME,RRE,x,c
Enable/disable satellite residual and position error message to port x, where x is the
output port, and c is ON or OFF. This message is not output unless a position is
computed.
Example: Enable RRE message on port A
$PASHS,NME,RRE,A,ON
$PASHQ,RRE,x
The associated query command is $PASHQ,RRE,x, where x is the optional output
port.
Example:
$PASHQ,RRE,A
$GPRRE/$GLRRE
The response message is output in two messages with different headers. The first
message contains GPS satellite information in the form:
$GPRRE,d1,n(d2,f1)f2,f3
The second message contains GLONASS satellite information in the form:
$GLRRE,d1,n(d2,f1)f2,f3
where n is equal to the number of satellites used to compute a position.
f7 Speed over ground, knots 000.00-999.99
f8 Course Over Ground, degrees True 000.00-359.99
d9 date, mmddyy 010100-123199
f10 Magnetic Variation, degrees 0.00-99.99
c11 Direction of Variation
Easterly variation (E) subtracts from True
course.
Westerly variation (W) adds to True course E => East
W =>West
