摘要
随着GNSS定位与数字通讯技术的不断提升,以CORS为代表的新型测绘技术,在矿山测绘、地形勘查中的应用日益广泛,其在确保开采质效的同时,降低了矿产资源开采成本。本文在探究CORS差分定位系统工作原理的基础上,从矿山工程测量的角度,阐述了坐标系统转换、全站仪配合GPS观测等方法,并对二者精度进行了对比分析,为类似工程提供参考依据。
With the continuous improvement of GNSS positioning and digital communication technology,the new surveying and mapping technology represented by CORS has been widely used in mine surveying and topographic survey,which ensures the quality and efficiency of mining and reduces the cost of mining mineral resources.On the basis of exploring the working principle of CORS differential positioning system,from the perspective of mine engineering survey,this paper expounds the methods of coordinate system conversion,total station cooperating with GPS observation,and makes a comparative analysis of their accuracy,providing reference for similar projects.
