Mechanism Analysis of Instantaneous Angular-rate Measurement of Gyro-test Turntable with Inertial Devices
Gyro is a key component of inertial navigation systems.How to increase gyro’s test and calibration accuracy remains a scientific problem which requires immediate solution in the field of inertial technology for all countries around the world.To improve the accuracy of gyro-test turntable is a most efficient way for increasing gyro’s test and calibration accuracy currently.Unlike the existing domestic methods,a new method is proposed in this paper that inertial devices (high-precision gyros and accelerometers) can be used for measuring instantaneous angular rate of gyro-test turntable directly,and high accuracy and stability of the rate of gyro-test turntable can be realized through rate feedback control in order to increase the accuracy of the turntable,thus realizing the goal of increasing gyro’s test and calibration accuracy furthermore.This paper analyzes mechanism of measuring instantaneous angular rate of gyro-test turntable by using this method,and discusses feasibility of this method,and points out a research direction for increasing the accuracy of gyro-test turntable.
