摘要
分析了地面沉降监测的精度需求,提出了在GPS观测中应用高性能软硬件条件,同时延长观测时间的技术方案,以苏锡常地区为例,实现了GPS技术在地面沉降监测工程中的毫米级应用。
The important factors that may have imfluence on the accuracy of GPS measurements, e.g. GPS receivers, observation network and data processing software are discussed. Meanwhile, an observation session of 12 hours or longer is preferred.
