Research on Key Technologies in Simulating Real-Time Operation of the Ground Segment of the Chang'E-2 Mission

We construct a simulation model of the real-time operation of the ground segment of the Chang'E-2(CE-2) mission by analyzing the structure and function of the ground segment. We analyze certain key technologies needed for the operation and subsequently design the simulation system to fit the operational functions. We finally give solutions for the key technologies based on a series of simulation tests and analyses. The paper provides a basis for the data simulation system of the ground segment of the CE-2 mission.
