摘　　要：全球卫星导航系统(Global Navigation Satellite System,GNSS)近年来得到了快速发展,南极地区GNSS的服务性能对科研活动有着重要影响,它的建设也是我国战略布局的重要环节。iGMAS平台是近年来建立的卫星导航系统的配套设施,能够对GNSS服务性能进行监测与评估,并生成相应报告,给GNSS的后期改进提供建议。对iGMAS平台进行了介绍,并给出服务性能评估模型。通过iGMAS平台,并使用南极中山站的监测数据对南极地区的GNSS服务性能进行监测评估,对仿真结果进行分析。实验结果表明,iGMAS平台能够完成对GNSS服务性能的监测评估。The Global Navigation Satellite System （ GNSS ） has been rapidly developed in recent years. The GNSS serviceperformance in Antarctic region is very important to scientific research activities,and its construction is an important part of Chinese strategic layout. The iGMAS platform is an auxiliary facility for satellite navigation systems established in recent years. It can monitor and evaluate the performance of GNSS services,and generate corresponding reports,making suggestions for the improvement of GNSS.Firstly,the iGMAS platform is introduced, and the service performance evaluation model is given. The monitoring and evaluation of GNSS service performance in the Antarctic region is carried out through the iGMAS platform and using the monitoring data of Antarctic Zhongshan Station,and the simulation results are analyzed. The experimental results show that the iGMAS platform can complete the monitoring and evaluation of GNSS service performance.
