Product Description and Technical Data

Product information "FURUNO SCX-21 Satellite Compass NMEA0183"

Revolutionary Baseline Architecture

Utilizing four separate GNSS Antennas for the ultimate in responsiveness, the SCX20 and SCX21 set a new standard for reliable and accurate heading for all of your marine electronics. Traditionally, a Satellite Compass™ calculates heading using one baseline between two antennas; the SCX20/21 four antennas can calculate heading information using any one of the six baselines drawn between the four antennas.

The unprecedented quad-antenna design of the SCX20 and SCX21 makes them capable of calculating extremely accurate heading, pitch, roll, and heave information. They are the perfect heading solution for complex vessel installations where the view of satellites may sometimes be obstructed.

Experience superior accuracy

The SCX20 and SCX21 enhance the performance of on-board equipment such as Radar, Fish Finders, Sonar, and Autopilots. Accurate heading information empowers your NAVpilot to keep a better course, saving time, fuel, and money on every voyage; meanwhile, precise pitch, roll, and heave information stabilizes the display for many Furuno Fish Finders and Sonars, allowing for an accurate presentation even in the roughest of seas.
