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.
