基于光纤陀螺的定向瞄准组合系统研究

Orientation and Aiming Integrated System Based on Fiber Optic Gyroscope

详细的论述了光纤陀螺定向、瞄准组合系统的基本原理,分析了各种误差对定向精度的影响,提出相应的补偿措施。测试结果显示在3min之内定向精度达到2′,可以满足导弹的近距离瞄准要求。

The principle of orientation and aiming integrated system based on fiber optic gyroscope is introduced. The reasons that caused the error of the orientation precision are analyzed, relative rotating technique and Kalman filter are adopted to improve the orientation accuracy. The test results show orientation accuracy is 2′ within three minutes, it is suitable for the missile aiming in the short range.
