Research on application of RTK altimetry to reservoir survey

简要介绍了基于载波相位观测的GPS RTK技术,讨论了GPS高程测量的技术、理论方法和数学模型;利用小浪底水库的实验资料研究分析了该技术在高程测量中应用的可行性和测量结果的精度;讨论了GPS RTK高程测量在水库测量应用中存在的理论和实际工作中遇到的问题,提出了水库GPS测量高程的处理方法,为GPS在水库测量中的应用提供了技术支持和借鉴的经验。

GPS PTK technology based on the carrier phase measurement is briefly introduced herein; in which the technique, theoretical method and mathematical model of GPS height survey are discussed, and then the feasibility and precision of the surveyed result of the apphcation of the technique used in the height survey are analyzed and studied in accordance with the experiment data of Xiaolangdi Reservoir. Furthermore, the problems occurred in both the practice and the theoretical study for the application of the technology to the reservoir survey are discussed as well; from which the processing method for the GPS surveyed height is presented at last. This study provides a technical support and some experiences to be referenced to the application of technology to reservoir survey.
