| 摘 要： | 根据高精度GPS变形监测的特点，以监测网的首期观测成果为基础，建立了单历元解算监测点变形量的似单差模型，讨论了接收机天线相位中心偏差的改正方法。该模型避免了周跳的探测与修复，可适用于动态、静态两种监测模式及单频接收机。利用三峡库区的实测数据对模型的正确性进行了检验。

| Abstract: | According to the characteristics of the high precise GPS deformation monitoring, basing on the first period observation results of the monitoring network,the similar single-difference model of solving GPS monitor point deformation information at single epoch is built,and the receivers'antenna phase center offsets are discussed.This model avoids the troublesome problem of cycle slip detecting and repairing,and is not only applicable to the static and dynamic monitoring modes, but also suitable for the single receivers.The correctness of the similar single-difference model is verified with the practical data in Three Gorge Area. |
