Zusammenfassung:	The invention provides a differential global navigation satellite system fault prediction method. The method comprises the following steps: acquiring historical fault data and daily record data of a differential station; according to the historical fault data, determining a relationship between the differential station fault and daily record data, and determining the daily record data strongly related to the differential station fault as fault data; predicting a future change trend of the fault data by adopting an artificial intelligence time sequence prediction algorithm to obtain prediction trend information; and pre-judging the fault condition of the differential station according to the prediction trend information so as to plan maintenance personnel in advance for maintenance, and broadcasting the difference station which stops providing the differential positioning information to the ship at the preset distance so as to ensure that the coastal ship obtains the information that the difference station doe
