结构变形监测的单频GPS动态三差法

Single Frequency GPS Dynamic three Difference Method for Structural Deformation Monitoring

主要对监测GPS中的似单差和单历元方法不足进行分析,并且针对性的提出了大变形、快速监测的单频GPS动态三差法,单频GPS动态三差法能够通过连续跟踪历元实现建模,动态变形提取,且无整周模糊度,单频载波定位和伪距单点定位能够分别满足基线向量和基准点的精度要求,单频GPS动态三差法适用于大于半个波长的量测。

of GPS monitoring in similar single difference and method of single epoch problems were analyzed, and for the proposed three large deformation, rapid monitoring of single frequency GPS dynamic difference, single frequency GPS dynamic difference method can through continuous tracking epoch to realize modeling, dynamic deformation extraction, and there is no ambiguity, single frequency carrier phase positioning and pseudo from single point positioning can meet the precision requirement of baseline vector and reference point, single frequency GPS dynamic difference method for greater than half a wavelength measurement.
