北斗卫星导航定位基准实时服务格网化方法OA
Grid Method for Real Time Service of Beidou Satellite Navigation and Positioning Benchmark
当前,北斗卫星导航定位基准实时服务以虚拟参考站定位模式为主,随着用户的不断增加,导致平台端运算压力陡增.针对该问题,提出了一种融合格网与地形信息的立体格网定位方法,并对格网划分策略进行了系统性研究.以山东省北斗卫星导航定位基准站网为例,选择16个野外测试点对格网化后的实时服务进行了实测验证,平面外符合定位精度优于1.5 cm,高程外符合定位精度优于2.0 cm.实现了厘米级增强定位,在满足网络实时定位精度的前提下,大幅降低数据中心的运算压力.
At present,the real-time service of Beidou satellite navigation and positioning benchmark is mainly based on VRS positioning mode.Accompanying with continuous increase of users,the computa-tional pressure increases sharply.In response to this problem,a three-dimensional grid positioning meth-od that integrates grid and terrain information has been put forward.Grid partitioning strategies have been studied systematically.Taking Shandong Beidou Satellite…查看全部>>
