Modeling and Simulating of Independent On-orbit Servicing Spacecrafts' Docking Process

The on-orbit servicing is an effectual method to extend the life and enhance the performance of spacecrafts.This paper established the kinematics and dynamics models of docking process of two on-orbit servicing spacecrafts with a new type docking mechanism,and three groups of contrast simulations and controls were done under different initial conditions,with the control systems established in ADAMS.The results indicate that the satellites can dock reliably in general initial conditions.In addition,some suggestions about design improvements were given,and the simulations can be a reference for the betterment of this type docking mechanism.
