| 摘 要： | SZ-GNSS CORS是苏州市重要城市基础设施，其中的高程基准是其重要研究内容。通过选取苏州GNSS控制网中的检测点，对这些检测点分别进行精密水准测量、静态GPS观测和GPS RTK观测，对观测数据进行处理和对比分析。结果表明，SZ-GNSS CORS的精化大地水准面模型效果良好，在一般情况下用GPS水准可以替代普通传统水准测量，能够满足苏州城市建设和信息化建设对高程基准的需求。

| Abstract: | SZ-GNSS CORS is an important urban infrastructure, of which the height datum is the focus. By se-lecting the benchmark points in Suzhou GNSS control networks, we made the precision leveling, static GPS ob-servation and GPS RTK observation. Then we processed and analyzed the observation data. The results show that SZ-GNSS CORS refining geoid surface model performs well and can generally replace traditional leveling. SZ-GNSS CORS can satisfactorily meet the demands of Suzhou urban construction and informatization construction to height datum. |
