Application of Computer Simulation Technology in Observing Effectiveness Analysis of the Satellite

摘要

With the development of computer and information technology, simulation technology has been promoted worldwide and is playing a more and more important role in the space mission. In this paper, the main requirements of spacecraft's observing effectiveness test during the general analysis were first analyzed. And the design of based simulation and test platform based on STK (satellite tool kit) was proposed. By using user-oriented system architecture, building up the high precision coordinate transforming relations and using domain decomposition algorithm, the path planning scheme focused on transformation from geographic coordinate space to the view plane were achieved. And the plan results were further tested using the two and three-dimension visual environment in the typical cases to provide an example for using STK simulation technology in engineering project.
