- 摘要:
- RTK(实时动态差分法)是基于载波相位观测值的实时动态定位技术,它能够实时提供测站点在指定坐标系中的三维定位结果,并达到厘米级精度。该技术应用到长输管道测量中能大幅提高测量效率和测量精度。文章以Trimble 5700 GPS接收机为例,介绍了RTK技术用于长输管道测量的基本原则、坐标转换参数的求取以及检验、中线位置的确定、数据采集格式、数据处理等。
Real-time kinematic method (RTK) is a kind of real-time kinematic positioning techniquebased on the carried wave phase observation data, which can offer three-dlimensional positioning in a specifiedcoordinate system for the survey station and reach the precision of centimeter order. The application of thistech nique in long-dlistance survey increases significantly the survey efficiency and precision. This paperdescribes the fundamental of RTK technique used for long-dlistance survey, coordinate transfer parametersacquisition and check, midline position determination, data acquisition format and data processing. In addition,it puts forward some opinions and matters for attention on outdoor measurements and indoor data processingwith Trimble 5700 GPS receiver for long-distance pipeline.2010,2(2): 125-126 收稿日期:2009-10-26分类号:TE973.1作者简介:桑悦(1974-),男,安徽宿松人,工程师,1998年毕业于中国地质大学(武汉)工程测量专业,现主要从事石油地面工程测量工作.参考文献:
