How Much Can a Satellite Compass Improve Your Navigation?

Satellite compass uses GPS carrier frequency and carrier phase to determine the true course of the carrier, so its performance is not affected by speed, latitude and longitude and geomagnetic field. Compared with traditional equipment such as magnetic compass and electronic compass, it has high precision, no drift, Significant advantages are maintenance-free and no calibration required.

     1. SC90 is a satellite compass using advanced GPS technology, which can be widely used on various ships. Radar/ARPA, AIS, electronic charts, scanning sonar and autopilots can all take advantage of the capabilities of this system. Because SC90 uses GPS carrier frequency to determine the heading direction, its performance is not affected by ship speed, latitude and longitude and geomagnetic field, etc., and the positioning is fast, and the ship steering tracking performance is as high as 90°/s (SOLAS high-speed ship stipulates that the minimum is 20°/s). 

    2. The satellite compass transmits GPS position information, SOG (speed over ground), COG (course over ground) and ROT (rate of turn). Meet the requirements for high-speed data transmission in specific environments.

Heading accuracy. You use less fuel when traveling point to point, both hand steering and using the autopilot, because you’ve got a heading system with almost no error. This information can be applied to all navigation, from autopilots to radar, to chart display and sonar. They all need accurate heading information.
