| 摘 要： | 利用GPS进行地面沉降监测具有覆盖范围广、不受气候条件限制、无需通视条件、自动化程度高等优势，但双频大地型GPS接收机的硬件价格比较高，难以大范围密集布设连续监测点。为降低硬件成本，采用单双频混合模式对广州南沙某lOOkm。区域进行了GPS地面沉降自动化监测设计，其中包括基准设计、网形设计、系统结构及数据处理方案设计。

| Abstract: | Monitoring land subsidence using GPS has many advantages such as wide range covering, no weather condition limited, high automatic. But dual-frequency geodetic-quality GPS receivers are costly, so it is difficult to set up dense monitoring points extensively. ＇In order to reduce the cost of GPS receivers in monitoring land subsidence, a mixed-mode GPS network for automatic monitoring land subsidence is designed in a 100 square kilometers area in Nansha of Guangdong Province. In the mixed-mode GPS network, single-frequency and dual-frequency receivers are used together. The monitoring network design includes reference points, distribution of the single and dual frequency GPS receivers, data processing methods and the system structure and so on. |
