【摘要】：当前，网络RTK技术已成为测绘领域的研究热点之一。但，该技术在我国工程建设领域尚未普及。并且，几乎很少对网络RTK的技术构建和应用方面进行系统地分析对比。故而本文认为有必要对其进行研究。文章在介绍网络RTK技术原理的基础上，主要对单基站网络RTK、移动基站式网络RTK和多基站网络RTK的基准站建设和技术构建流程做了详细的研究，并对比分析各自的优缺点，总结出对工程建设具有参考价值的建议。最后，通过具体实验研究了坐标转换参数对测量精度的影响，，包括已知点含有微小误差对测量精度的影响、控制网的大小不同对测量精度的影响两部分内容。然后，又比较分析了三种形式的网络RTK测量精度与距基准站距离的关系，在10km、20km、35km范围内对所选的测试点进行实时动态测量，并对测试数据的测量精度进行分析比较。得出三种形式的网络RTK在什么样的范围内保证5cm的测量精度。提出具有一定实际应用价值的建议。
[Abstract]:At present, network RTK technology has become one of the research hotspots in the field of surveying and mapping. However, the technology has not been popularized in the field of engineering construction in China. Moreover, few systematic analysis and comparison are made on the technical construction and application of network RTK. Therefore, it is necessary to study it in this paper. On the basis of introducing the technical principle of network RTK, this paper makes a detailed study on the base station construction and technical construction flow of single base station network, mobile base station network RTK and multi-base station network RTK, and compares and analyzes their advantages and disadvantages. The suggestions of reference value for engineering construction are summarized. Finally, the influence of coordinate conversion parameters on measurement accuracy is studied through experiments, including the influence of small errors in known points on measurement accuracy, and the influence of different control network size on measurement accuracy. Then, the relationship between the measurement accuracy of three kinds of network RTK and the distance from the reference station is compared and analyzed. The real-time dynamic measurement of the selected test points is carried out in the range of 10 km / 20 km2 / 35km, and the measurement accuracy of the test data is analyzed and compared. The range of three types of network RTK to ensure the measurement accuracy of 5cm is obtained. Some suggestions with practical application value are put forward.
