摘　　要：为了进一步研究BDS卫星在高精度矿区滑坡变形监测领域的应用,在对BDS目前运行系统的观测与星座设计分析的基础上,讨论GNSS单历元实时高精度算法模型的特点以及实现实时定位所需要的条件,进而提出基于单历元算法的适用于短基线变形监测需要的模糊度搜索法。实验结果表明,BDS数据能够满足单历元高精度变形监测的精度要求。同时给出BDS与GPS单历元算法解算精度的比较分析结果,为BDS在高精度定位领域的相关研究提供参考。In order to further study on the application of BDS in the field of high-precise landslide and deformation monitoring for mining area,based on the analysis of observation and constellation design of the current operating system of BDS,the paper discussed the characteristics of GNSS single-epoch real-time high-precise algorithm models and the conditions for real-time positioning,and proposed an ambiguity searching algorithm suitable for short baseline deformation monitoring based on single epoch algorithm.Experimental result showed that BDS data could provide the required accuracy of high-precise single-epoch deformation monitoring.Moreover,the comparative analysis between the single epoch algorithms of BDS and GPS would provide a reference for the application of BDS in high-precise positioning.
