Satellite navigation signal spoofing interference detection method, processing device and system

Abstract

Relating to the field of satellite navigation, provided are a satellite navigation signal spoofing detection method, a satellite navigation signal processing system, and a satellite navigation signal processing device, the method comprising: acquiring at least two GNSS satellite navigation signals received in real-time by means of two or more navigation signal receiving antennae (S11); processing each GNSS satellite navigation signal to acquire corresponding information related to each navigation signal (S12); performing difference processing on the information related to each navigation signal of each navigation signal receiving antenna to acquire a difference processing equation (S13); solving the difference processing equation to acquire a difference solving result (S14); and, on the basis of the difference solving result, determining whether there is satellite navigation signal spoofing (S15). The present method can effectively and reliably identify the presence of satellite navigation signal spoofing.

Description

technical field [0001] The present application relates to the fields of radio navigation and satellite navigation, and in particular to a satellite navigation signal spoofing interference detection method, a satellite navigation signal processing system, satellite navigation signal processing equipment, electronic equipment, and a computer-readable storage medium. Background technique [0002] The satellite navigation system is a major breakthrough in human science and technology in the 20th century. By deploying navigation satellites on tens of thousands of kilometers of orbits and transmitting navigation signals, it solves the problem of positioning and timing efficiently and at low cost. At present, the satellite navigation system has become a national Infrastructure has penetrated into all aspects of public life, especially since the era of intelligence, location services based on satellite navigation are even more indispensable. However, since the power of the navigatio...

Problems solved by technology

However, due to the fact that the power of the navigation signal transmitted by the satellite to the ground is very weak, and the structure of the civilian navigation signal is open, it is easy to be interfered and deceived. Among them, the deception signal is more concealed and the harm is more serious. Conventional radio detection methods cannot detect the existence of the deception signal.

At present, the commonly used deception detection methods mainly include multi-peak detection, signal quality detection, etc., but none of them can guarantee reliable detection of deception signals.
