火炮弹丸捷联式地磁—太阳方位rn姿态测量模型研究

摘要

For use in the attitude measurement of artillery projectiles, a strap-down type geomagnetism and solar direction sensor is made use of to decide the attitudinal data. A theoretical attitude measurement model is set up, referred to the respective directions of geomagnetism and the sun．Through detailed study and analysis,the model and method of measurement given adapt well to cases of projectile attitude measurement in the environment of high g shoot and high rate of revolution.%为了测试火炮弹丸飞行姿态，采用捷联式地磁—太阳方位传感器，利用地磁场和太阳方位作为参照物，解算弹丸飞行姿态。本文给出了解算弹丸姿态的数学模型和测试方法以及解算所应满足的条件，提供了对高过载、高转速弹丸姿态测试的有效方法。
