| 摘 要： | 1995年以来,天津市控制地面沉降工作办公室在天津市内陆续布设了一批永久性GPS观测点。本文作者利用十年的重复观测结果分析了这些点的相对高程变化,并与精密水准测量结果进行了比较,讨论了它们的差异和一致性,最后估计了GPS方法测定地面垂直变化的精度。

| Abstract: | Since 1995,many permanent GPS stations have been established in Tianjin by Tianjin municipal office of settlement monitoring.The relative altitude variations at these points were analyzed using ten years replicated observations in this paper,and they were compared with the results of precise leveling by the authors.The difference and coherence between these two results were discussed.Finally,the precision of GPS method to check the vertical variation was evaluated. |
