A hybrid weighted Fourier transform and relaxation (hybrid-WRELAX) method applied to Loran-C skywave delay estimation is presented. The performance of this method is demonstrated and compared with the spectrum analysis method. The hybrid-WRELAX method has been proved to provide higher accuracy to estimate the Loran-C skywave delay. Results testify this conclusion using off-air data.
