The proposed method is based on a general analysis model of group delay using Fourier series decomposition. The channel group delay is decomposed into a series of cascaded trigonometric group delays, and the compensation effect of filters of different orders on group delay is tested through experiments. The analysis results show that compared with the traditional infinite order based all pass filter, only a 5th order filter is needed to compensate for group delay fluctuations up to 150ns. The filter order is much lower than that of traditional group delay calibration filters, and the compensated pseudorange deviation is less than 0.1m.
