Dynamic modeling and simulation of an on-orbit self-maintenance system for satellites

The sketch map of a satellite model and robot arm is built up. In terms of the law of conservation of momentum, an expression is set up that indicates the relationship between the manipulator speed and satellite and robot arms movement. Under the environment of micro-gravity, the operation of sun mirror of satellites is simulated. The result showed that the rotating speed of arms does not affect the final position of satellites and that the angle rotated decides the final position of the satellite.
