南方CORS系统在数字化测图中的应用

随着RTK技术在数字化测图方面的应用日益广泛,但对地形复杂测区,普通RTK技术常遇到诸多问题,造成作业效率低下。而CORS系统中的网络RTK技术是GPS-RTK技术进一步延伸,采用网络通讯大大延伸了RTK的作业半径,提高了定位精度和可靠性,以工程项目为例,详细介绍了网络RTK技术在数字化测绘中的应用。

Application of South CORS System in Digital Mapping

Currently, the technology of RTK in digital mapping are applied widely, hut in the area of difficult, common RTK technology often encounters problems which lead to operating inefficiency. But the network RTK of CORS system is the further extension of GPS-RTK technology, using network communication can greatly extend the operational radi- us of the RTK, and the positioning accuracy and reliability is improved. Taking engineering project for example.the application of netnork RTK is introduced in digital mapping.
