Furuno SC Satellite Compass.

Furuno SC70 and SC130 Satellite Compasses

The Furuno SC70 and SC130 represent Furuno's latest generation of commercial-grade satellite compasses, offering exceptionally precise heading and attitude data to enhance the performance of marine electronics such as Radars, ARPA, Sonar, Chart Plotters, ECDIS, and Autopilots.

By utilizing multiple GNSS constellations—GPS, Galileo, GLONASS, QZSS, and SBAS—the SC70 and SC130 provide continuous, highly accurate positioning and heading information essential for safe navigation. They deliver a full suite of navigational data including GPS position, Speed Over Ground (SOG), Course Over Ground (COG), Rate of Turn (ROT), and 3-axis vessel speed critical for maneuvering, including berthing.

The SC70 model delivers heading accuracy of approx. 0.4°, with a rapid 40°/s follow-up rate—twice the IMO high-speed craft requirement—and features a 4.3” color LCD display with 480 x 272 WQVGA resolution. The SC130 is designed for medium to large vessels, offering higher precision sub-degree heading accuracy (0.25°) and uses the NMEA2000 interface for seamless integration.

Both compasses are maintenance-free, rugged, and ideal for retrofitting into existing navigation systems. The SC70 can be installed easily using existing antenna cabling with an optional LAN conversion kit.

Models:

• SC70 Satellite Compass (NMEA0183)

• SC130 Satellite Compass (NMEA2000, with 4.3" Color LCD Display)
