| 摘 要： | 根据高精度GPS变形监测的特点,建立了单历元解算变形量的似单差模型及其算法.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同步观测卫星少于4颗的情况.在分析似单差模型的基础上,提出了识别载波相位观测值中小于半周的粗差的方法.利用试验数据对似单差模型的正确性及粗差识别方法的有效性进行了检验.

| Abstract: | According to the characteristics of the precise GPS deformation monitoring, the similar smgledifference model and its algorithm for solving deformation values at single epoch is built. This model avoids the troublesome problem of cycle slip detecting and repairing, not only applicable to the static and dynamic monitoring modes but also suitable for the case that the synchronous satellites are less than four. On the basis of analyzing the similar single-difference model, the method of identifying the outliers, which is in carrier phase observations and less than half a cycle, is put forward. The correctness of the similar single-difference model and the validity of the method of identifying outliers are verified with the test data. |
