Designed for integrated bridges and advanced high-speed vessels. The operation principle is based on the invariance of light (Sagnac effect). It uses three fibre-optic coils (gyroscopes) and a dual-axis electronic level sensor and a Kalman filter to determine the direction of true north. Solid state sensor that has no moving parts and does not require a gimbal. Includes 12 analogue and digital repeaters, and 2 dependent 6 steps/degree heading outputs. Heading accuracy is <= 0.7 degrees secant latitude. Roll/pitch angle accuracy is <= 0.5 degrees. Rate of turn accuracy is < = 0.4 degrees/min. x/y rate accuracy is <= 0.4 degrees/min."@en ; skos:notation "SDN:L22::TOOL1607" ; skos:note "accepted"@en ; skos:prefLabel "Sperry Marine NAVIGAT 2100 gyrocompass"@en ; skos:related , . pav:hasCurrentVersion .
