Product Overview

Furuno SCX21 Compact Dome Satellite Compass, NMEA0183

Model: SCX21

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’s 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.

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.

Directly connect any Furuno or compatible NMEA0183 equipment to distribute high speed and accurate heading, position, speed, roll, pitch and heave as well as air temperature and barometric pressure. Connect a Furuno GP39 Display to control and configure the flexible SCX21 Output ports. Select 4800 low speed/38400 high speed data and enable, disable, or control the repetition interval of the individual strings of the individual outport ports.

When connected to Furuno SCX20/21, the Radar’s echo trails hold steady and clearly depict an accurate echo trail thanks to the SCX20/21’s amazing accuracy. Company A’s satellite compass fails to uphold a steady heading, making echo trails virtually unintelligible. Company B’s heading accuracy fluctuates by +/- 3? with a slower update, causing an echo trail that has a wide zig-zag pattern. Company C’s heading accuracy fluctuates by +/- 5? with a faster update, causing an echo trail that is indistinguishable and confusing.

Expert Overview

The Furuno SCX21 Satellite Compass is a maritime navigation device designed to provide accurate heading, pitch, roll, and heave data. It utilizes a quad-antenna GNSS design, calculating heading information from six possible baselines between its four antennas. This design enhances responsiveness and reliability, particularly in complex vessel installations where satellite visibility may be obstructed. The SCX21 integrates with existing marine electronics, including Radar, Fish Finders, Sonar, and Autopilots, to improve their performance. It outputs NMEA0183 data, supporting direct connection to compatible equipment for distributing high-speed heading, position, speed, roll, pitch, heave, air temperature, and barometric pressure. This unit is suitable for IT buyers managing marine systems requiring precise navigational data for operational efficiency and display stabilization.
