摘　　要：因目前没有针对小视场星跟踪器的室内测试设备,而外场试验和试飞试验成本高、难度大,为了对组合导航系统的算法和性能进行测试,本文设计了一种基于小视场星跟踪器的天文/惯性/卫星组合导航半实物仿真系统。该系统根据实际采集的导航源数据建立误差仿真模型,产生仿真数据,结合组合导航系统原理样机中的导航处理器和显控单元实物模块,形成半实物仿真系统。它具有很强的灵活性和可扩展性,可有效地降低组合导航系统的实验成本,缩短研制周期,对研究组合导航系统的算法性能、系统特性和工程应用等具有重要理论和实践意义。Because there is not indoor test equipment for narrow field of view(FOV)star tracker,and outfield experiment andactual flight will involve a lot of efforts such as heavy financial budget and high difficulty.To debug the performance and testalgorithms of the integrated navigation system,a hybrid simulation system of celestial navigation system/inertial navigationsystem/global navigation satellite system(CNS/INS/GNSS)integrated navigation system based narrow FOV star tracker wasproposed.The system emulates the error simulation model based on the actual collected navigation source data,generates thesimulation data,and then combines the navigation processor and the display control unit in the prototype of the integrated navigationsystem to form the hybrid simulation system.It has a feature of flexibility and extensibility and can be used to reduce effectively theexperimental expense and shorten the developing period of integrated navigation system,which is significant for studying algorithmperformance,system specialty and project application of integrated system.
