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.

• 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。
