航天器系统级测试现状分析

Current Situation Overview of Spacecraft System Level Test

从测试方法、测试计划、测试模式、测试用例设计方法、测试工具等方面对航天器系统级测试进行了探讨。测试方法主要包括测试覆盖性分析法、自上而下或自下而上的测试方法、面向对象或面向过程的测试方法等;测试计划参考了NASA航天器的分类方法,包括对低成本卫星、商业卫星及载人航天器等三大类航天器进行了论述;测试模式包括任务组织方式、测试系统部署方式及人员配置等;测试用例设计方法包括软件测试方法、基于模型的测试方法及试验测试方法等;测试工具主要包括手动工具、自动化工具、信息化管理工具等三个发展阶段。此外,文章还对当前航天器系统级测试的现状及面临的问题进行了分析。

This paper try to discuss the system level test of spacecraft in the aspects of test methodology,test plan,test mode,test cases design method and test tool.From the testing methodology aspect,testing coverage analysis method,up-to-down or down-to-up method,object-oriented or process-oriented method are discussed.From the testing plan aspect,low cost satellite,commercial satellite and manned spacecraft are discussed according to the classification of spacecraft in NASA.In the testing mode aspect,task organization mode,test system deployment mode and the staff allocation mode are discussed.In the test case design aspect,software testing method,model-based testing method and test method are discussed.In the testing tools aspect,manual tool,automatic tool and information management tool are discussed.And then,the current situation and the problems are given.
