针对实景三维中国建设项目中在西部区域部分区域控制点无法利用RTK获得CGCS2000坐标成果的实际,本文提出采用PPP-AR(Precise Point Positioning-Ambiguity Resolution)和坐标转换相结合的方法,首先利用PPP-AR得到观测历元下控制点厘米级的定位结果,其次通过坐标转换中的框架转换和历元归算将计算结果转换为CGCS2000坐标的成果,确保实景三维中国建设项目顺利开展.
Application of PPP-AR and Coordinate Transformation in Realistic 3D China Construction
In response to the inability of RTK to obtain CGCS2000 coordinate results for control points in some areas of the western re-gion of the realistic 3D China construction project, this paper proposes a method based on the combination of PPP-AR (Precision Point Positioning Ambiguity Resolution) and coordinate transformation. Firstly, PPP-AR is used to obtain centimeter level positioning results for control points under observation epochs. Secondly, the calculation results are transformed into CGCS2000 coordinate results through the framework transformation and epoch reduction in coordinate transformation, ensuring the smooth implementation of the re-alistic 3D China construction project.
