[Abstract]:Inertial navigation is an autonomous closed navigation method which can provide the speed, position and attitude information of the carrier in real time. With the rapid development of science and technology, strapdown inertial navigation technology based on computer technology began to develop rapidly, and gradually replaced the old platform inertial navigation system. However, the strapdown inertial navigation system still has the same problem as platform inertial navigation system, that is, the calibration and compensation of initial error. The error of the inertial measurement element is the main error source of the inertial navigation system, so the calibration and compensation of the error parameters of the inertial measurement element will directly affect the accuracy of the inertial navigation system. Based on this, this paper mainly studies the following aspects: (1) according to the error propagation characteristics of strapdown inertial navigation system, the influence of gyro drift on system error is analyzed. The influence of gyroscope drift on system error is analyzed by long time simulation experiment, which is mostly oscillatory error. (2) the calibration technology of inertial navigation system is studied. The discrete calibration and system level calibration are introduced, and the advantages and disadvantages of the two methods are analyzed. In this paper, a system-level calibration method is used to calibrate the starting zero bias of gyroscope step by step. The calibration results and attitude errors after compensation show that the calibration accuracy of this method is high and the calibration method is simple. The calibration time is short. (3) taking MEMS gyroscope as an example, the method of measuring the random error of gyroscope is studied. In this paper, the random error of gyroscope is analyzed and measured by Allan variance method in IEEE standard. The feasibility of using Allan variance analysis method to analyze the random error of MEMS gyroscope is verified by experimental analysis. (4) the precision detection method of fiber-optic strapdown inertial navigation system in practical engineering is studied, and the static internal coincidence is proposed in this paper. The precision testing method of static external coincidence, dynamic internal coincidence and dynamic external coincidence is proved to be of high accuracy by the experimental results, which meets the precision detection requirements of fiber-optic strapdown inertial navigation system (fiber-strapdown inertial navigation system).
