Fiber optic gyroscope compass is a new generation of strapdown compass system for civilian ships. It uses advanced fiber optic gyroscope and strapdown calculation technology to autonomously measure the ship's angular motion, and has the ability to continuously provide the carrier's heading, pitch, roll and other information to the outside world, providing basic information support for ship navigation at sea. Fiber optic gyro compasses have the advantages of long lifespan, maintenance free, short start-up time, low cost, and no need for regular replacement of gyro balls, which can completely replace traditional gyro compasses.
