导航卫星有效载荷在轨测试系统设计研究

摘要

The in⁃orbit test of navigation satellite payload can be used to implement overall detection for operating status of navi⁃gation satellite,so it is important for satellite after the satellite launched.The in⁃orbit test system is the professional equipment for detec⁃ting function and performance specifications of navigation satellite,and it can be used to simulate all functions of ground⁃control system. This paper introduces the composition of payload based on operating principle of navigation satellite,puts forward the design scheme of in⁃orbit test system,describes the basic composition of system and functional characteristics of equipment,and analyzes the key tech⁃niques of system.%导航卫星有效载荷在轨测试是卫星入轨后的重要试验，通过在轨测试实现对导航卫星运行状态的全面检测。在轨测试系统可以全面模拟地面运行控制系统的功能，是检验导航卫星功能和性能指标的专用测试设备。针对导航卫星的工作原理对有效载荷的构成进行了简要介绍，根据被测对象，提出了在轨测试系统的设计方案，描述了系统设备组成及各设备的功能特点，并对在轨测试系统中的关键技术的实现进行了分析。
