The invention provides a satellite navigation deception jamming detection method based on generalized RDSS positioning, and belongs to the technical field of satellite navigation. According to the method, on the basis of a traditional Beidou dual-mode receiver, detection and identification of deception jamming signals are achieved through an original pseudo-range verification mode based on generalized RDSS positioning, and meanwhile, traversal and verification of pseudo-range observed quantities of all RNSS satellites are achieved by using RDSS positioning as a passive handshake positioning mode and using generalized RDSS as a positioning mode integrating RDSS and RNSS. According to the method, all satellite number pseudo-ranges are identified through RDSS positioning, generalized RDSS positioning, RNSS positioning and satellite number polling traversal modes, identified deception signal information is recorded and output in an alarm mode, and real-time detection of deception jamming of the satellite navigation receiver is completed.
