technical field
[0001] The invention belongs to the technical field of inertia, and mainly relates to a gyro north-seeking device, in particular to a north-seeking device using an optical fiber gyro as a sensitive element. technical background
[0002] Chinese patent application CN90103687.0 discloses a kind of north finder invented by the 15th Institute of the First Design and Research Institute of the Ministry of Aeronautics and Astronautics of my country. The north finder uses a flexible gyroscope and an accelerometer installed on the turntable as the detection components. The components of the earth's rotation angular velocity at multiple positions are detected by the flexible gyroscope. Combined with the output of the accelerometer at the same position, the solution Calculate the angle between the initial position and the north direction. A stepper motor is used to drive the turntable to rotate to realize the sampling of multiple measurement pos...
