Design and Implementation of Universal Satellite Semi-Physical Simulation Platform

In order to improve the efficiency of satellites’house-keeping software development,eliminate the influence of satellites’hardware development progress on software development,and promote the development of satellites’simulation platform generalization,this paper presents a design and implementation method of universal satellite semi-physical simulation platform.The platform is composed of two parts:the satellite computer simulator and the single computer simulation simulator of on-board electronics.Using the idea of general and modular design,we develop the satellite computer simulator with general characteristics and the single computer simulation simulator of on-board electronics with flexible and configurable characteristics,the standardized and reconfigurable multi-communication interface and the intelligent system test interface,and then integrate a set of universal satellite semi-physical simulation platform.Using this platform,the development and design of satellite software for several types of satellites are carried out.It is verified that this platform has strong generality for different types of satellites.Using this platform for software development improves the efficiency of satellite software development,and ensures that the software is available once delivery.
