GPS dynamic deformation analyse based on wavelet transform
Li Xuan · Cehui kexue · 2008
The principal of wavelet denoising is introduced and the replicability of GPS multipath effect in dynamic environment is discussed firstly.Then,a systemic multipath error correction model is presented by applying wavelet denoising to static observation.Finally,the dynamic observation is corrected.Experiments prove that remain denoises after multipath model correction are accord with normal distribution,and the precision of dynamic deformation monitoring can be improved.
