Research on Test and Evaluation System of Multi-mode Composite Receiver

多模复合导航技术以其高精度的导航制导性能,在精确制导武器等领域获得了广泛的应用,随之带来了多模复合导航装备的测试评估的问题,传统的卫星导航测试技术难以满足其高精度、动态的测试需求,也缺乏针对基于卫星导航的相关应用性能测试手段。针对这一技术问题,通过对国外已建设的测试系统的技术分析,设计了一种基于伪卫星和导航模拟器的先进复合接收机综合测试评估系统,提出一种测试评估体系架构,分析研究了系统中所涉及的组合导航模拟、伪卫星系统基线网络等关键技术问题,基于外场测试环境提出一种构建方法并进行了分析评估。

Multi.mode complex navigation with high precision navigation and guidance performance is widely used in precision.guided applications,while traditional satellite navigation test methods cannot meet its precision and dynamic test requirements,and there is a lack of methods for performance testing of satellite.based navigation application.Therefore,a composite test and evaluation system based on pseudolite and GNSS simulator is designed,a test and evaluation architecture is proposed,and some key techniques involved are analyzed,such as integrated navigation simulation,pseudolite system network and so on.Finally,a system scheme based on outdoor testing environment is presented,and its performance is analyzed.
