摘要
利用监测点变形前精确位置已知的条件,反求出双差相位观测值的整周模糊度;利用单历元观测数据,通过多种载波相位组合,获得高精度的变形值,当瞬间变形值较大时(0.5m),也能获得满意的效果。
In the case that the accurate coordinates of the monitoring point and reference station are known, the ambiguities of double difference phase observations are obtained. When the deformation is relatively, large high precision deformation value can be derived from the combination with different carrier phase observations. Using single epoch observations in the data processing, continuous monitoring can be achieved.
