| 摘 要： | 发射原点是飞行器试验中非常重要的参数,在某些特殊试验中,发射原点往往是不能准确给出的,为此,本文详细推导了发射原点误差对发射方位角和弹道精度的影响公式。仿真计算结果证明,原点误差对发射方位角影响较大,而原点误差和发射方位角误差的共同作用对发射系下的弹道精度影响很大,对于此类高精度的飞行器试验必须考虑原点误差对弹道精度的影响。

| Abstract: | Launch origin is a very important parameter in spacecraft tests,but an accurate launch origin is often unavailable in special experiment missions.This paper derives in detail the impact formula of launch origin error on launch azimuth angle and trajectory accuracy.Simulation results show significant impact of launch origin error on launch azimuth angle.Considering the outstanding combined impact of launch origin error and launch azimuth angle error on trajectory accuracy under the launch coordinate system,a... |
