ONWA, KEC-70G Digital Compass

Heading Sensor for Radar/ARPA, AIS, ECDIS, Scanning Sonar
KEC-70G provides GPS information, Lon/Lat, SOG and COG, with Pitch and Roll Function
Used with High Accuracy Onwa Marine Heading Sensor KA-GC9A, Satellite Compass KA-SC20 or KA-SC90
Can Correct Magnetic Deviation Manually or Automatically
Provide NMEA0183 and NMEA2000 Heading and GPS Output
2 NMEA0183 output are RS422 Electrical Interface
There are no mechanical parts such as gimbals or rotating motor, thus the compass is free from routine maintenance.
