| 摘 要： | 为了将验潮站得到的海平面变化信息与难潮站所在陆地垂直运动分离开来，获得海平面变化的绝对信息，在我国沿海５个难潮站建立了一个高精度的ＧＰＳ陆海垂直运动监测网，采用ＧＡＭＩＴ和Ｇｌｏｏｋ软件对数据进行处理，并顾及影响高程因素中由于方位不对称引起的大气延迟改进的Ｎｉｅｌｌ模型，我们最终得到ＧＰＳ监测网毫米级的高程精度。

| Abstract: | A high precision GPS monitoring network, which consists of five tide gauge stations, was established along the coastal line to separate the sea level changes information obtained by the tide gauge stations from the vertical continental movement at the tide gauge stations. We used GAMIT and Globk software and the improved Niell model in the data processing and took into account of the atmospheric delay, which is from azimuth asymmetry and has influence on the height measuring. At last, we achieved the mm level precision on height measuring. |
