摘　　要：单历元变形解算存在很多先验信息,文中将单历元变形解算的每一次解算结果作为下一次解算的先验信息,采用新的解算模型对单历元变形量进行解算,并用数据进行了验证,证明了先验信息会使计算结果更加接近真值。A lot of priori information existed in the single epoch solution. In the paper, the each solution results of single epoch deformation solutions were used as the prior information of the next solution. New calculation model was used to calculate the deformation of the single epoch and verified by the data, the results proved that the prior infor- mation would make the results closer to the true value.
