摘　　要：针对传统卫星研制过程中,算法版本更迭,测试周期长的问题,提出一种基于模型系统工程(MBSE)的数字卫星测试环境构建方法;通过建立数字卫星模型和仿真测试环境,以数据驱动的方式实现数字模型与物理模型的交互,能够支持卫星全系统全生命周期的仿真测试和半物理硬件在环测试;解决了卫星系统硬件不具备测试条件时的全系统仿真测试问题,实现了对卫星软件功能和接口协议的提前测试、优化,缩短了测试周期、规避了测试风险;此外,该系统的仿真测试环境不依赖传统的工控机和测试机箱,从而降低了测试系统复杂度和构建成本。In order to solve the problems of algorithm version updates and long testing cycles in the process of traditional satellite development,a method for constructing digital satellite test environment based on Model-Based Systems Engineering(MBSE)is proposed.By establishing a digital satellite model and simulation test environment,the interaction between digital models and physical models can be realized in a data-driven way,which can support the simulation testing and semi-physical hardware-in-the-loop testing for the whole life cycle of the satellite system.It solves the problem of full system simulation testing without the test conditions in the satellite system hardware,realizes the testing and optimization of satellite software functions and interface protocols in advance,and shortens the test cycle and avoids the testing risk.In addition,the simulation testing environment of the system not only relies on traditional industrial computers and test cases,but also reduces the complexity and construction cost of the testing system.
