摘要
用户应用系统是卫星导航系统结构的组成部分,卫星导航系统的功能与作用均是建立在用户设备中发挥效益,同时用户对于卫星导航设备的软硬件需求日益增加。以卫星导航接收机的性能测试为例,介绍了用户设备的基本工作原理和用户设备测试方法,以接收机设备为核心研究了接收灵敏度、伪距测量精度等诸多性能测试指标与方法,并设计出1套模拟用户测试的场景模板,为卫星导航用户接收机的测试提供了理论指导。
The user application system is an integral part of the structure of the satellite navigation system.The functions and roles of the satellite navigation system are built in the user's equipment to exert benefits.At the same time,the user's demand for the software and hardware of the satellite navigation equipment is increasing day by day.In view of this,based on the performance of the satellite navigation receiver test as an example,this paper introduces the user equipment testing method and the basic working principle of user equipment,receiver equipment as the core research the receiving sensitivity,pseudorange measurement precision,and many other performance testing index and method,and designed a set of simulated user testing of templates,It provides theoretical guidance for the test of satellite navigation user receiver.
