ActiveCN104777493ASimple stepsGood deceptionSatellite radio beaconingSatelliteReal signal
The invention discloses a signal generating method for achieving preset track deception and provides a deception jamming wired test system. According to the method, by utilizing a true satellite position observed by a receiver at a t moment and the true position of the receiver, a deceiving side can simulate and generate M branches of deception signals through a preset deception track, the M branches of deception signals and a true satellite participate in localization calculation of the receiver simultaneously, and a location result is obtained. By means of the method, the multiple branches of deception signals different from a PRN code of the true satellite can be generated, and a great deception effect can be achieved by only a few branches of deception signals. The deception jamming wired test system can generate N branches of true signals and the M branches of deception signals by setting a true movement track and the deception track of an object, after combining the N branches of true signals and the M branches of deception signals, the deception jamming wired test system transmits the combined signals to a GNSS receiver, and the deception jamming effect can be judged by comparing the location result output by the receiver with the preset deception track in real time.
