Commands
$PASHQ,CRT,[x]
This command allows you to query the CRT command, where x is the optional
output port. If a port is not specified, the receiver sends the response to the current
port.
$PASHR,CRT
The Cartesian coordinates and velocities message contains information on the
antenna position, number of satellites, altitude, speed, velocity, and dilution of
precision. The message is output in the format:
$PASHR,CRT,d1,d2,m1,m2,m3,m4,f2,f3,f4,f5,f6,f7,f8,f9,s*cc
Table 4.71 defines the message format.
