| Abstract: | Aiming at the requirements of high-precision CGCS2000 geodetic datum construction in coastal cities of south China,taking Jiangmen City for example,we discussed and analyzed the strategies of baseline calculation and network adjustment calculation respectively,and established a high-precision geodetic datum framework.The results show that adopting high-precision GAMIT/GLOBK data processing software,setting a small sampling interval and increasing a certain observation time can provide a reference for high-precision CGCS2000 geodetic datum construction,and provide high-precision geodetic datum data basis for subsequent quasi-geoid refinement. |
