IRNSS卫星导航系统性能分析The performance analysis of IRNSS

摘要(Abstract)：
针对2016年组网成功并正式服役的IRNSS卫星导航系统的服务性能评估问题,该文采用STK软件基于ICD文件提供的导航卫星轨道参数模拟了IRNSS系统的服务区域及相关导航性能,并且利用MGEX网的实测数据对IRNSS系统在澳洲境内的服务性能进行了评估分析。分析结果表明:IRNSS系统可以向其主要服务区内用户提供基本的独立导航定位服务;可向澳洲西北部地区用户提供平面方向精度32m以内、高程方向精度41m以内的定位服务;当与其他导航系统联合使用时,IRNSS系统增加了用户的可用卫星数量,有效提升了GNSS系统的定位精度。本文较好地克服了当前IRNSS测站少的困难,初步实现了对IRNSS系统服务性能的全面评估。
