摘要
简述GPS控制网设计的基本原理,阐明在水利工程控制测量中选择合适的GPS控制网对于提高观测质量和精度,减少外业观测工作量等方面具有重要意义。通过对水利工程施工中布设的GPS控制网点连式、边连式、边点混连式控制网进行技术、经济、可靠性对比分析,得出合理的GPS控制网布设方案。
The paper makes a brief introduction to the basic principle for design of GPS control network.It indicates that the selection of appropriate GPS control network in control surveying of hydraulic engineering has great significance in increasing observation quality and accuracy and in decreasing the quantity of filed observation work.A reasonable GPS control network scheme is obtained based on the technical,economical and reliability comparisons of the point style,edge style and edge point mixed style GPS control networks in hydraulic engineering.
