NMEA GXP (Position Horizontal)
$PASHS,NME,GXP,X,Y
This command enables/disables the position horizontal message on port x, where x is
either A, B, or C, and y is ON or OFF. This message is not output unless position is
computed.
Example: Output GXP message on port C
$PASHS,NME,GXP,C,ON followed by output command
$PASHS,OUT,x,NMEA where x is the output port.
$GPGXP
The response message is in the following form:
$GPGXP,hhmmss:ss,ddmm.mmmmm,s,dddmm.mmmmm,s*cc
