摘要
为提高椭圆轨道落点预测精度,提出了基于光测数据的落点预测方法。首先介绍了椭圆轨道运动的约束条件,然后建立了基于轨道约束自校准技术的落点预测算法模型,最后给出了典型情况下的落点预测仿真结果。仿真结果表明:采用光测数据进行椭圆轨道的落点预测是可行的,通过轨道约束自校准技术可以对光测设备系统误差进行高精度校准,提高了椭圆轨道落点预测精度。
In order to improve the precision of impact point prediction of elliptical orbit, a method of impact point prediction based on opti- cal measurement data was presented. Firstly, the constraint conditions of elliptical orbit was introduced. Then, the algorithm model of im- pact point prediction based on the technology of orbit restrain self-calibration was set up. Finally, the simulation results of impact point pre- diction in typical eases were supplied. The simulation results show that the prediction method based on the optical measurement data is fea- sible, the systematic errors of device can be precisely calibrated by the technology of orbit restrain self-calibration,and the precision of im- oact ooint orediction can be imoroved.
