Investigation of the Dynamic Behaviour and the Frequency Response of the Gg 1342Laser Gyro

摘要

The dynamic behavior of a laser gyro under conditions of angular vibrations andconstant rates of rotation is investigated on a single axis turntable. It is demonstrated that a laser gyro for inertial navigation also meets flight control requirements. The gyro behavior is represented by power density spectra of its measured rate of rotation and by its transfer function. A measuring system consisting of inductosyn, tachometer, and linear accelerometer serves as hybrid rotational speed reference. The characteristics of the gyro rate measurements, for example the measurement noise and the other reaction motion, are discussed.
