%X For taking the problem in Compass two order ionospheric correction,the algorithm of wavelet package de-noising is used to weaken the noises before ionospheric delay correction.Finally,the experiment is made by Compass emulational data and the results show that wavelet packet de-noising method can decrease the observation errors and enhance the feasibility and validity of triple-frequency of two order correction greatly.
