A Common Ground Experiment Testbed for Synthetic Mission Demonstration of Small Satellites

摘要

AThis paper introduces the development of a ground experiment testbed for synthetic mission demonstration of small satellites in National University of Defense Technology (NUDT). This testbed consists of five parts: test platform, small satellite simulator, monitoring and control system, data collecting and simulation system, and displaying system. It can simulate small satellite motion with two or three degree of freedom by means of smooth granite platform and air bearing system, and support hardware-in-the-loop simulation. This experiment testbed has been applied to several multi-satellite mission demonstration projects, including the formation flying of three small satellites, the rendezvous and docking of two small satellites, the on-orbit refueling demonstration, etc. The experiment processes as well as the results of these experiments are given in this paper.
