Motion simulator system for rendezvous and docking needs high precision and high real-time capacity. The main structure, crucial indexes and control system structure are introduced at first. Software demand is also analyzed, software is modular designed, makes use of fine interface of Windows, use real-time processing ability of RTX and high precision of control algorithm. The experimental results show that the motion simulator system for rendezvous and docking based on RTX have the high
