Winsock在网络RTK数据传输中的应用

The application of Winsock in the data transmission of network RTK

网络RTK技术具有覆盖范围广、定位精度高、可靠性强等优点,在测量与导航领域得到了广泛应用。网络RTK系统一般由基准站网、计算与控制中心、系统用户和必要的数据通信链路四部分组成,快速、可靠的数据传输是网络RTK的必要条件。本文介绍了Winsock以及如何利用Winsock在Visual C++环境下实现网络RTK的数据传输。测试结果表明,本文的方法可以用于基准站与计算与控制中心、计算与控制中心与后处理用户间的数据传输,并具有高速、简捷、稳定的优点。

Network RTK has many advantages such as abroad action area, high accuracy, more reliability etc, and is widely applied in surveying and navigation. The network RTK system is composed of base station networks, system center, system clients, and necessary link of data transmission. The rapid and reliable data transmission is the prerequisite of network RTK. This paper introduces Winsock to data transmission of network RTK with Visual C ＋ ＋. The test results indicate that the method in this paper can be used in the data transmission between base station networks and system center, system center and post-processing users. Furthermore it has the advantages of velocity, simplicity and stability.
