基于卫星导航系统的导弹姿态测量算法研究

Research on Missile Attitude Measurement Algorithm Based on Satellite Navigation System

弹体姿态测量是导弹飞行试验的重要组成部分,对于评估导弹控制系统性能、分析导弹飞行状态、改进飞控系统设计都具有重要作用。导弹自身惯性系统可进行姿态测量,但其误差随时间增加而累积且发散,在远距飞行时误差明显。卫星导航系统具有精度高、误差不随时间积累的特点,利用多天线阵列相对精密定位技术,可实现导弹姿态的高精度测定,为导弹姿态测量提供一种全新的思路。

The attitude measurement is an important part of missile flight test. It plays an important role in evaluating the performance of the control system,analyzing the flight status of the missile and im-proving the flight control system design. The missile 爷 s own inertial navigation can be used for attitude measurement,but its error increases with time and accumulates and diverges over time,and the errors are larger in long-distance flight. Satellite navigation system has high precision characteristics, and its error does not accumulate over time. The multi-antenna array relative positioning technology can realize the high precision test of the missile attitude,and provide a new approach for the attitude measurement.
