摘　　要：为综合评定卫星导航接收机的各项性能,需在测试中模拟接收机的各种工作环境。该软件可根据用户需求,通过设定一系列的测试场景参数,模拟产生卫星星座、用户轨迹、观测数据、导航电文等数据,并可根据测试项目合理产生和控制各种误差,同时为满足特殊测试的需求,软件还提供对导航电文、天线模式等信息的编辑功能,为物理信号的产生提供数据支持,并为接收机性能指标的评定提供参考基准。经在建的用户机测试系统验证,利用本软件设计的测试场景,能够较为科学准确的评价导航型用户机的各项性能指标。In order to evaluate the performance of the satellite navigation receiver, it is necessary to simulate the receiver＇s various working environments in testing. Software was developed which can simulate many kinds of data such as satellite constellation, user trajectory, observations and navigation message by specifying some testing scene parameters corresponding to the user＇s requirements. In order to satisfy certain special requirements, the software was designed to have many functions, such as editing the navigation message, antenna pattern and some other information, providing data support for the generation of physical signal, and providing the reference standards of receiver performance. The receiver testing system verifies that the various performance specifications of navigation receiver can be evaluated scientifically by using the testing scene of our software.
