The Method of predicting Gyroscope drift Errors Based on Grey System

摘要：

Gyroscope is the key sensitive devices in inertial navigation system (INS) ，and gyro drift is main error of INS. The error of gyro consists of constant drift, random drift, and scale factor error. Whether gyro random drift model is is correct or not will have a important role in precise of inertial measurement unit (IMN).The model of certain dynamically tuned gyroscope and temperature is constructed so as to compensate drift, to improve the precision of dynamically tuned gyroscope based on grey system theory in this paper. The experiment results show that precision is improved by this model, and this method is very easy to use.
