摘要： 应用航天器相对运动动力学Ｃｌｏｈｅｓｓｙ－Ｗｉｌｔｓｈｉｒｅ方程，求出方程的分析解，研究航天员出舱后的运动轨迹。其结论可推广到对接航天器分离后的运动轨迹、卫星和运载分离后相对运动轨迹、航天器上抛射物体的相对运动轨迹

Abstract: This paper discusses the application of the Clohessy-Wiltshine equation of spaceship relative motion dynamics to find its analytical solutions.We can rely on these solutions to study the motion track of an astronaut coming out of the spaceship.And these solutions can be applied to other conditions,such as the motion tracks of separated spaceships,the nelative motion tracks of a separated satellite and its launch vehicle,and the relative track of a projected object out off the spaceship.
