摘　　要：GNSS/INS组合导航系统近年来得到了快速发展,应用领域越来越广泛。组合导航的定位精度是一个重要的研究方向,本文将应用于航空遥感领域的高精度GNSS/INS组合导航系统放置在地面平台上,采集试验数据,通过与NRTK定位结果比较,对组合导航系统定位精度进行分析,得出GNSS/INS组合导航系统的定位精度可达到厘米级的试验结论。Recent years, the integrated GNSS/INS navigation system has developed rapidly, its application field becomes more widely. The positioning accuracy of integrated navigation is an important research direction. In this article, carrying out a test, in the test the high-precision integrated GNSS/INS system used in aerial remote sensing field is placed on the ground platform, then collecting test data, by comparing integrated GNSS/INS navigation＇ s positioning results with NRTK＇s positioning results, analyzing positioning accuracy of the integrated navigation system. It is concluded that the positioning accuracy of the integrated GNSS/INS navigation system can be achieved centimeter level.
