Multi-dimensional domain satellite navigation deception jamming detection method based on dual-frequency fusion

The invention provides a multi-dimensional domain satellite navigation deception jamming detection method based on double-frequency fusion, and belongs to the technical field of satellite navigation. According to the method, capturing, tracking and positioning of space visual satellite signals are normally completed based on a traditional design architecture of a satellite navigation receiver; then single-frequency deception jamming recognition is achieved through verification of double-frequency satellite numbers and ephemeris, clock correction and almanac information differences in telegraph texts; detecting a deception jamming signal by using the dual-frequency ionosphere error fitting value; and performing mutual difference fitting on the double-frequency ionosphere error fitting value and an ionosphere error value of an ionosphere model in the telegraph text which is positioned and analyzed by the receiver, and detecting the deception jamming signal again by using the fitting error. The method is not lim
