摘要
在弹箭飞行遥测中,采用基于MEMS传感器的惯性测量组合(IMU)来测试弹箭飞行姿态数据,该方法构成的测试系统体积小、抗过载高、功耗低、数据处理简单直观可靠、对弹载结构改动不大且成本低。给出了该测试方法原理以及四元数解算方法,并对四元数初值进行了分析,在此基础上给出了仿真计算结果。
In the telemetry of rocket and cannon projectiles,we can use IMU based on MEMS sensors to measure flying attitude of projectile. The test system based on IMU technology is characterized by small size, withstanding high overload,low power loss, lost cost and simple data processing. In this paper, we descibe the test principle of the test method and quaternion resolving algorithm,analyze the quaternion initial value and describe quaternion renewal. Finally, we gives the simulation calculation result.
