| 摘 要： | 介绍一种实现GPS中长基线实时动态(RTK)定位的方法,研究基于M-W组合搜索双频GPS载波相位模糊度的方法,最终使用消电离层LC载波相位组合观测量进行相对定位。车载试验结果表明,对于双频GPS接收机,流动站距离基准站50km以内,使用本方法RTK定位可以达到5cm(RMS)的点位精度。

| Abstract: | In this paper,a middle-long baseline real time kinematic(RTK) positioning method is introduced.The Melbourne-Wubbena(M-W)combination method for dual-frequency GPS carrier phase integer ambiguity resolution is studied,and the relative positioning is implemented with the iono-free LC carrier phase combination observation finally.The vehicle-mounted experiments show that the RTK positioning can reach 5cm accuracy for dual-frequency GPS receiver,assuming that the rove stations are within 50km from the base stat... |
