Beschreibung
Zusammenfassung:	The invention provides a method for monitoring the double-almanac data fault of a satellite navigation regional augmentation system, which comprises the steps that an onboard device receives the navigation parameters which are sent by satellite navigation monitoring equipment, the navigation parameters comprise the false dismissal probability of the double-almanac data fault and the false dismissal probability of the single almanac data fault, the almanac decorrelation parameters of the double-almanac data fault and the almanac decorrelation parameters of the single almanac data fault; according to the navigation parameters, the calculation formulas of a single almanac data fault protection class and a double-almanac data fault protection class are utilized, so the single almanac data fault protection class and the double-almanac data fault protection class are obtained; and according to the single almanac data fault protection class and the double-almanac data fault protection class, the probability that two
