| Abstract: | Due to the Rotation Modulation Laser Gyro Inertial Measurement Unit, the characteristics of the errors are analyzed. A method of IMU rotating is presented, which is based on the both-direction rotating and whole-week rotating. In this research, the method can get the errors curve exactly, and the various items of the error are modeled into three parts. Experiments prove that this method significantly improves the accuracy of the system, and is effective in the Real-time error compensation. |
