Abstract

The invention relates to a satellite navigation deception recognition method and device, and belongs to the technical field of satellite navigation deception detection. The method comprises the stepsthat navigation parameters observed by an INS and navigation parameters observed by a GNSS are acquired; the error values of the navigation parameters observed by the INS and the navigation parametersobserved by the GNSS at the corresponding moments are calculated; if the error values of at least ten successive epochs are greater than a set threshold, that a satellite is deception is judged, thenavigation parameters observed by the GNSS are abandoned, and the INS is adopted for navigation; and if the error values are smaller than the set threshold or the error values which occur accidentallyare greater than the set threshold, a combined navigation mode of fusing the navigation parameters observed by the GNSS and the navigation parameters observed by the INS is adopted for navigation. The problem that in the prior art, in a combined navigation mode, an existing satellite navigation deception detection method is complex and not thorough is solved.

Description

technical field [0001] The invention relates to a satellite navigation fraud identification method and device, belonging to the technical field of satellite navigation fraud detection. Background technique [0002] The Global Positioning System (GPS, Global Position System) can provide three-dimensional coordinates and speeds on a global scale, but satellite navigation signals are susceptible to interference or spoofing, which makes the carrier unable to navigate safely. In the military field, the spoofing of navigation signals can be fatal . With the construction of the four major international global satellite navigation systems (GNSS, Global Navigation Satellite System) GPS, GLONASS, BDS and GELILEO, satellite navigation plays a more important role in core infrastructure such as economy, transportation, and electricity. In actual navigation, the safety of navigation has received more and more attention, and how to overcome the problem that GNSS is susceptible to interfer...
