摘要
GPS定位技术以其连续、实时、高精度、全天候测量和自动化程度高等优点,在工程中的应用越来越广泛,GPS大型控制网已经在水电工程中得到了广泛应用。通过参与GPS大型控制网工程实践,对控制网中起算点的检验以及高程拟合等若干问题进行探讨,并结合具体工程实例对其进行分析说明。
Global Positioning System(GPS) has be more and more widely used in engineering due to its 24 hours availability,real-time,high precision,operability under all weather conditions and automation,and the application of GPS technology in water conservancy is widely adopted.This paper explores some questions such as methods for checking starting point accuracy and elevation fitting in GPS control network based on the practice and also analyses the application through detailed engineering examples.
