The invention discloses a GNSS single station double-frequency observation data cycle-slip detection and processing method based on fuzzy mathematics. Whether there is a cycle slip in the observation value is determined by determining the membership of the variation of the ionospheric delay between the epochs and the variation of the MW combined observation value between the epochs, and the descending weight processing is performed on the observation value, in which the cycle slip is hard to determine. According to the invention, the problem that the threshold is difficult to reliably determine during the cycle slip detection data processing in the prior art can be effectively solved, and the GNSS precise data processing precision and reliability can be improved.
