Description: This proprietary Leica message provides the current Position and Quality in
either Geodetic or Grid coordinates for one or two antennas plus the resulting orientation.
☞ Information regarding the second antenna is not applicable for the iCON gps 160 SmartAntenna.
Access: Select Settings > Tools > NMEA Output. Toggle to Edit for NMEA Out 1 or
NMEA Out 2. ORP is available on the second page of the wizard
Description of fields 
1 Control Type
