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 ,利用监测时段的载波相位为基本观测量 ,建立了单历元解算监测点变形信息的似单差模型 .该模型避免了周跳的探测与修复 ,可适用于动态和静态 2种监测模式 ,并可适用于同步观测卫星较少 (如 2颗 )的情况 .According to the characteristics of high precision GPS deformation monitoring, based on the first period observation results of the monitoring network, and using the carrier phases of the monitoring session as the basic observations, the similar single-difference model of solving GPS monitor point deformation information at a single epoch is built. This model avoids the troublesome problem of cycle slip detecting and repairing. It is applicable to both static and dynamic monitoring modes, and suitable for the surroundings that the synchronous satellites are less than four. The correctness of the similar single-difference model is verified with the test data.
