【摘要】 介绍RTK技术的产生、发展、应用现状以及RTK的组成、测量精度指标、软件系统。以鞍钢鲅鱼圈工程及鞍钢厂区技术改造为例,研究在具体工程中如何施测RTK、提高RTK的测量精度,拓宽RTK的应用范围。通过实例和具体数据证明利用静态GPS测量的解算数据求得WGS84坐标和地面坐标的转换参数,根据工程对精度的要求设置RTK观测的历元数,能够提高RTK的测量精度和工作效率,满足工程的需要。更多还原

【Abstract】 It presents the origin, development and application of RTK technology. It takes the case of Mackerel Rim engineering and Plant Technological Transformation Project in Anshan Steelworks as examples. It discusses the application of RTK technology especially in its measurement, adoption and accuracy .It obtains WGS84 coordinate and transfer parameters of earth coordinate in terms of static GPS measurement through detailed data and instances. It sets the epoch observed by RTK in terms of the accuracy requirement of survey engineering, in order to improve RTK measurement accuracy, working efficiency and meeting the need of survey engineering.更多还原
