摘要： 由于发射时熄火点产生的误差,需要有一种误差分析以便确定运载火箭的制导精度。本文介绍了飞行路径上的小误差对航天器轨道的影响,接着讨论了确定制导精度的方法并给出了圆轨道的简化公式。

Abstract: An error analysis is neccessary to determine the guidance accuracy due to errors at burnout accurring at launch. This paper presents the affect of small errors of the flight path on the vehicle orbit, subsquently, also discusses the method to determine the guidance accuracy and gives the simplified formula for the circular orbit.
