    摘要: A GNSS satellite signal handling method is disclosed. For a specific Doppler bin, when a peak is found, it is checked if the specific Doppler bin is polluted with interference by detection. If the detection result indicates that the specific Doppler bin is polluted with interference, a threshold, which is used to determine whether the actual signal peak is found or not, is then raised to a higher level, so as to increase the searching reliability. To detect interference, it is determined whether the specific Doppler bin is polluted by comparing a statistical value of correlation results of a plurality of code chip hypotheses with a reference or by checking if there are plural peaks existing in the power spectrum.
