Research on Satellite Selection Algorithm of GNSS Repeater Deception Jamming

In modern electronic warfare, the GNSS repeater deception jamming has been an important method of jamming. With the research on satellite selection algorithm of GNSS repeater deception jamming, the jamming ability of repeater deception jamming can be improved. A satellite selection algorithm was proposed based on the satellite selection method of common GNSS positioning and PDOP contribution of single satellite. The simulations were carried out based on the pseudorange single positioning method with the least-squares algorithm, under the static and dynamic conditions respectively. And the receiver attacked by repeater deception jamming with single satellite was simulated under both static and dynamic conditions. The simulation results show that the satellite selection algorithm for repeater deception jamming proposed in this paper can provide the theoretically optimal star selection result with high probability.
