弹丸姿态解算初始地磁分量误差分析
|
摘要
提出了地磁三分量对弹丸姿态角解算的影响,建立了弹药姿态角解算模型,利用初始地磁信息和实测地磁信息,已知偏航角求出另两个姿态角。对初始地磁分量的误差带来姿态角误差的影响建立了数学模型,求解出在常规地磁误差下分析误差。仿真结果表明,地磁分量对姿态角解算能够产生具体影响,甚至存在无解的情况,一个良好的初始地磁信息精度是非常重要的。
The influence of geomagnetic three components on the attitude angle of projectile was proposed.An ammunition attitude angle calculation model was established. Using the initial geomagnetic information and the measured geomagnetic information,the other two attitude angles were obtained under the known yaw angle. A mathematical model was established for the influence of the error of the initial geomagnetic component on the attitude angle error, and the specific size of the error was analyzed under the conventional geomagnetic error. The simulation results show that the geomagnetic component has a specific influence on the attitude angle,and in some cases even no solution is generated,so a good initial geomagnetic information accuracy is important.
