摘要
针对旋转弹姿态测试中导航误差随时间积累过快的问题,提出了由加速度计和磁强计构成组合测试系统。针对一种十二加速度计配置方案,利用拟牛顿法解决了姿态解算的问题。仿真结果表明,该算法能有效的抑制误差的积累,有助于提高导航精度。
An integrated test system with accelerometers and magnetometers was proposed to solve the problem of the accelerated accumulation of navigation errors in the attitude measurement of spinning projectiles.An attitude algorithm based on quasi-Newton method was used for a twelve-accelerometer configuration.The simulation results show that the algorithm can suppress the accumulation of errors effectively and meet the requirement of navigation accuracy.
