| 摘 要： | 为了研究用GPS观测取代常规的水准测量方法来监测城市沉降变化的可行性，在宁波市建立了有7个点组成的GPS基准网和14个点组成的GPS监测网。在观测中采取了一定的措施，以获得高精度的高程分量。用Bernese软件对数据进行处理时顾及到对流层延迟的影响，采用Saastamoinen模型，获得了mm级的高程精度，这将有助于提高沉降监测的效率。

| Abstract: | The feasibility of monitoring the change of city settlement using GPS surveying instead of leveling is studied. A fiducial network consisting of seven fiducial sits and a monitoring network consisting of fourteen monitor sits are established in Ningbo city. Some measures are taken during the observation in order to ensure to obtain the high precise height component. Considering the effect of tropospheric delay, Saastamoinen model is adopted when Bernese software is used to process the data. The mm-level precision on height measuring is achieved. It helps to advance the monitoring efficiency. |
