摘要
为有效促进渡河工程保障侦察手段的改进和侦察装备的发展,综合运用实时动态定位GPS-RTK(real tim e k inem atic)、超声波测深和数字测图等技术实现数字化江河测量。介绍了RTK方式江河测量总体构想,阐述了测点定位、水深测量和流速测定的技术原理,提出了测线控制和数据传输的解决方案。与传统测量手段相比,RTK方式具有高效率、高精度、全天候和实时性等优点,是渡河工程侦察的一个重要发展方向。
To improve and develop the method and equipment of river-crossing reconnaissance, digital river surveying was implemented with GPS-RTK (real time kinematic), ultrasonic sounding, and digital mapping technology. The main design was introduced, and the technical theories of RTK orientating, depth surveying and flow velocity mensurating were expounded. The solution to two important problems, survey-line control and data transfer, was brought forward. Compared with traditional measures, RTK has merits of high frequency, high precision, all weather, and real time. So it is a trend of development of river-crossing reconnaissance in the future.
