摘要
Abstract
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 Navigation and Positioning Reference Station Network as an example,selecting 16 field test points,real-time service after grid has been tested and ver-ified.The out of plane coincidence positioning accuracy can reach within 1.5 cm,and the out of elevation coincidence positioning accuracy can reach within 2.0 cm.The centimeter level enhanced positioning has been realized.Under the premise of meeting the real-time positioning accuracy of the network,the com-puting pressure of the data center has been greatly reduced.关键词
