3D-Aided-Analysis Tool(3DAAT) which is a virtual reality system is built up in this paper. 3DAAT is integrated with kinematics and dynamics model of rover as well as real lunar surface terrain mode. Methods of modeling which are proposed in this paper include constructing lunar surface, constructing 3D model of lander and rover, building up kinematic model of rover body. Photogrammetry technique and the remote sensing information are used to generate the terrain model of lunar surface. According to the implementation result, 3DAAT is an effective assist system for making exploration plan and analyzing the status of rover. 3D-Aided-Analysis Tool (3DAAT) which is a virtual reality system is built in this paper. 3DAAT is integrated with kinematics and dynamics model of rover as well as real lunar surface terrain mode.
