摘要
为探究Trimble RTX后处理(RTX-PP)用于海洋测绘领域填海验收测量的可行性,以港珠澳大桥项目东人工岛、西人工岛为例,利用RTX-PP技术在线解算控制点ITRF2014框架当前历元坐标,通过历元转换及框架变换得到控制点2000国家大地坐标系(CGCS 2000)坐标,与静态解算成果对比,点位精度不超过±0.05 m,满足规范要求。表明RTX-PP可应用于填海验收平面控制点测量。
In order to explore the feasibility of Trimble RTX post-processing(RTX-PP) used in marine surveying field reclamation acceptance survey,taking the east artificial island and west artificial island of the Hong KongZhuhai-Macao Bridge project as examples,the RTX-PP technology was used to solve the current epoch coordinates of control points ITRF2014 frame online,and the CGCS 2000 coordinates of control points were obtained through epoch conversion and frame transformation.Compared with the static calculation results,the point accuracy did not exceed±0.05 m,which met the requirements of the specification.It shows that RTX-PP can be applied to the acceptance plane control measurement of completed sea area of the reclamation projects.
