Furuno’s SCX-20 (NMEA 2000) and SCX-21 (NMEA 0183) satellite compasses enhance the performance of onboard electronics such as radar, fish finders, sonar and NAVpilot autopilots by providing super-accurate heading information and precise pitch, roll and heave data to stabilize the display. The system uses four separate GNSS antennas and quad-core processing to deliver 1.0 degree heading and 0.02 knot‑speed accuracy, even when line of sight is limited to a single satellite.
