摘　　要：小卫星编队飞行技术的应用需要突破构形保持、姿态协同等复杂的关键技术难题。在一定逼近度下建立地面仿真环境,既可用于测试与验证复杂关键技术解决方案的有效性和可行性,又大大降低了系统研制代价和新技术应用的风险性。根据HLA(高层体系结构)分布式仿真技术,设计实现了小卫星编队飞行分布式仿真平台。仿真平台包含小卫星编队构形维持控制、重构控制和小卫星姿态指向一致控制等模块,具有对仿真结果的统计分析能力。同时以成像高度计三星编队为例,利用仿真平台进行了数字仿真,验证了该平台的可行性以及小卫星编队飞行构形维持和姿态指向一致控制模块的有效性。Many complex technical problems such as formation keeping and attitude coordination need to be solved in application of small satellite formation flying technology. If simulation environment is developed under a certain degree of approximation, not only the validity and feasibility of the solutions to key technologies can be tested and verified, but also the cost of system development and the risk of new technology application can be reduced. Based on the simulation technology of HLA （High Level Architecture）, a distributed simulation platform for small satellite formation flying is designed and implemented. This platform which includes control modules of formation keeping, formation reconfiguration and attitude coordination, has the capability of statistic analysis of simulation results. A simulation example of three satellites formation for altitude imaging is given, and the simulation result verifies the feasibility of the platform, as well as the validity of modules of formation keeping and coordinated attitude control.
