摘要： 论文针对母星在轨释放小卫星安全速度设计开展研究。在考虑母星机动变轨约束条件下,基于Hill方程推导了分离速度的解析表达式,并与考虑了多种摄动因素的数值解进行了比对,误差的量级为10-3m/s。可为在轨释放安全分离速度的确定提供一种迅速准确的解析算法。

Abstract: The safe releasing velocity of small satellite which was launched from the main satellite was investigated.An analytical solution for the safe releasing velocity was presented based on the Hill equation in the constraint of the main satellite's maneuvers.The error compared with the numerical solution which has considered perturbations was at the level of 10-3m/s.This research provides a quick precise solution for the on-orbit releasing velocity design.
