基于所需导航性能要求的导航激励器设计

Design of Navigation Exciter Based on Required Navigation Performance Requirements

导航激励器模拟机载导航系统是对航电系统进行符合性测试的重要设备。基于性能导航的应用要求,导航激励器能遵循所需导航性能要求,产生相应的测试导航参数。在传统导航激励器设计的基础上,分析了基于性能导航运行的系统需求,按照所需导航性能要求进行了系统设计,着重讨论了导航性能监视,并进行了软件设计。测试结果表明所设计的导航激励器达到了设计要求,能输出符合导航性能要求的测试导航参数。

The navigation exciter simulates the airborne navigation system and is an important equipment for the compliance test of the avionics system.The application of performance-based navigation requires the navigation exciter to follow the required navigation performance requirements and generate the corresponding test navigation parameters.Based on the design of traditional navigation exciter,this paper analyzes the system requirements of performance-based navigation operation,designs the system according to the required navigation performance requirements,focuses on the navigation performance monitoring,and designs the software.The test results show that the designed navigation exciter meets the design requirements and can output test navigation parameters that meet the navigation performance requirements.
