B&G Gimballed Rate Compass

B&G Instruments
Gimbaled Rate Compass

Normally a single-axis gyro is fixed in the plane of the boat, this means that when the boat is heeled the rate- gyro is susceptible to errors when the boat pitches fore and aft - ironically this often makes the performance worse than a non-stabilised fluxgate! 

The Gimballed Rate Compass (GRC) has been designed to bring the full advantage of a single-axis rate-sensor to the sailing market.  The GRC utilises a gimballed rate-gyro, ensuring that the sensor is always measuring the true yaw rate, independent of any heel and trim effects.  The GRC also integrates high-accuracy heel and trim sensors which can supply data via the Halcyon Gyro Processor or ACP Pilot. Heading data is also available via 10Hz NMEA output. 

The GRC solves this problem by gimballing the rate-sensor, ensuring that it is always measuring the true Yaw Rate, independent of any heel and trim effects.  The GRC also integrates high-accuracy Heel and Trim sensors.
