摘要
针对惯性传感器对高速旋转体姿态测量时,测量结果误差大且存在漂移的问题,提出基于单轴磁传感器的高精度、高可靠性高速旋转弹姿态解算算法。该算法采用地磁数据零点信息求解旋转体姿态的基本原理,在已知试验场地地磁参数情况下进行了磁传感器安装角度的选择及修正,利用地磁数据实现对旋转弹体全弹道的飞行姿态的解算。炮射实验验证结果表明,利用该算法进行旋转弹姿态解算误差较小,精度较高,并易于实现,具有一定的工程应用价值。
A high-precision,high-reliability and high-speed algorithm of rotating projectile attitude calculation based on a single-axis magnetic sensors was proposed to solve the problems of large error and drift in measurement results.Based on the basic principle of solving the attitude of the rotating body by using the zero point information of the geomagnetic data,the algorithm realized the selection and the correction of the installation angle of the magnetic sensor under the known geomagnetic parameters of the test site,and calculated the full trajectory flight attitude of rotating projectile.The algorithm was verified by artillery shooting test.The experimental results showed that the algorithm had smaller error,higher accuracy,and was easy to implement.
