摘要
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。
The in-orbit test of navigation satellite payload can be used to implement overall detection for operating status of navigation satellite,so it is important for satellite after the satellite launched. The in-orbit test system is the professional equipment for detecting 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 techniques of system.
