摘　　要：随着网络RTK技术的普及,测量作业可采用RTK的形式布设图根控制点,传统方法会将WGS-84坐标通过网络平台转为地方坐标,然后手动输入全站仪进行摆站测绘地物点坐标。针对全站仪数据后处理问题,以南方测绘NTS-391R全站仪数据为例,本文提出一种基于Fortran语言的后处理解算碎部点方法,该方法利用Fortran语言开发了一套软件,该软件仅由外业输入虚拟控制点坐标代号,就可通过内业后处理的方式解算碎部点坐标。实验表明,该方法大大节省了外业作业时间,提高了工作效率,同时减少了人为出错的可能,为全站仪数据后处理提供了一种新思路。With the popularization of network RTK technology, RTK can be used to arrange mapping root control points in survey operation. The traditional method will transform WGS-84 coordinates into local coordinates through the network platform. Then the total station is inputted manually to survey the coordinates of the ground objects. Aiming at the problem of data post-processing of total station, taking the data of NTS-391R total station of southern surveying and mapping as an example, this paper proposes a method of post-processing calculating the detail points based on Fortran language. This method uses Fortran language to develop a set of software. The software only inputs the coordinate code of virtual control point by field work, and then solves the coordinates of detail points by post-processing by interior work. The experiment shows that this method can save field work time, improve work efficiency, reduce the possibility of human error, and provide a new idea for data post-processing of total station.
