A seamless fast UAV navigation decoy system

Abstract

The present invention proposes a seamless fast UAV navigation and decoy system, including a radar monitoring subsystem, which is used to monitor the position of the UAV in real time, and obtain the current time system of the UAV and the current geodetic coordinates of the UAV The position information under the system; the computing platform is used to calculate the pseudo-range information between the current position of the drone and each real visible star in the sky according to the ephemeris parameters and the position information of the drone; the deception signal generation subsystem is used to The atomic time corresponding to the UAV's internal receiver, the position information of the UAV and the pseudo-range information of the real visible star are simulated in real time to generate a deception signal; the signal transmitting subsystem is used to send the deception signal to the target UAV. In the present invention, by generating a false star with the same pseudo-distance from the UAV to the star in the sky, the spoofing signal can be quickly and seamlessly connected to the receiver of the UAV, and the receiver does not need to go through processes such as loss of lock and recapture, which greatly shortens the The access time is shortened, and the deception efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of navigation attack and defense, and in particular relates to a seamless fast unmanned aerial vehicle navigation deception system. Background technique [0002] In recent years, the UAV industry has developed rapidly, and the application of UAVs has exploded in both military and civilian fields. Several incidents of black-flying drones interfering with flight flights have resulted in alternate landings, hundreds of flight delays, and tens of thousands of passengers being blocked and stranded at the airport. Therefore, from the perspectives of urban airspace security, terrorism prevention, and maintenance of public security, it is urgent to take strong control measures against black-flying or malicious black-flying UAVs. [0003] At present, most of the control and interference methods for black flying drones use high-power radio suppression interference and navigation signal deception. Although the method...
