Beschreibung
Zusammenfassung:	The invention provides a satellite navigation pseudorange abnormality real time detection method. The method includes: utilizing characteristics of high-frequency output and short-time high accuracy of an inertial navigation system; taking a reasonable range to which pseudorange of a satellite navigation system belongs; establishing detection standard information used for directly detecting satellite navigation pseudorange abnormality in real time without introducing filtering parameters of a combined navigation system; detecting pseudorange abnormality of the satellite navigation system in real time. The method is simple, easy to implement, high in instantaneity, satellite navigation pseudorange abnormality information can be effectively eliminated, and reliability of the satellite combined navigation system is improved.
