The Research Of Satellite Simulation Based On Space Mission

With the development of space application, in order to verify and evaluate the feasibility of design scheme, satellite platform should be simulated as a whole one in the assessment of space scientific mission which aiming at special exploring object. Thus, it is necessary to build the satellite platform simulation system orienting the space scientific mission. The main contents of this thesis are listed as follows:Firstly, the thought, characteristics and constitute of High Level Architecture (HLA) were introduced. It is illustrated that HLA distributed simulation technology can meet the design requirements of satellite design and has important value for application in simulation of space mission.Secondly, based on the study of satellite system and the analysis of its simulation task, the simulation purpose and the composing of satellite system were discussed. The simulation of satellite system was divided into three parts including of orbit & attitude control system simulation, power supply system simulation and data management system simulation. Then, models of every simulation system were described detailedly. Totally, a middleware technology and 14 simulation models were referred in this thesis.Thirdly, the structure and interface of Space Mission Simulation System were briefly introduced; also, the data interaction of satellite federate in space mission simulation was described; According to the characteristics of satellite simulation task, the structure and interface of satellite federate are designed and programmed to realize based on HLA. Finally, based on the example of Panda-1 Satellite, the feasibility, commonality and validity of simulation platform were verified. This platform also owns statistic analyse ability for simulation result.
