A cyberattack where false GPS/GNSS signals are transmitted to a receiver.

Unlike jamming, which entirely blocks or disrupts GPS/GNSS signals, spoofing alters the signals to deceive a receiver into accepting incorrect data. This manipulation can lead to the display of false information regarding aircraft position, speed, or time, potentially causing dangerous outcomes in applications that rely on accurate GPS/GNSS data.

This navigation signal simulation module adopts GNSS signal simulation technology, covering BDS, GPS, GLONASS and Galileo. It generates real-time satellite signals identical to genuine ones to mislead drone positioning receivers.

It enables multiple low-altitude UAV safety management: heading guidance, diversion, smooth forced landing and controlled crash. With radar cooperation, it can guide drones to designated landing spots.

Customizable in functions and performance, it serves petroleum, power, public security and safety protection industry.

• Realize full-area, all-weather, long-distance autonomousfull-area all-weather long-distance low-altitude UAV safety management.
• Spoof navigation-dependent UAVs to achieve diversion, heading guidance, no-fly zone control, smooth forced landing and rapid crash; precise fixed-point landing guidance with radar assistance.
• Customize flight trajectory of target UAVs, freely combine uniform speed, acceleration and circular motion control modes.
• Manual & automatic transmit power adjustment modes for flexible adaptation to different control distances.
• Automatically identify spoofing radius, dynamically optimize spoofing performance and suppress co-frequency interference.
• Manual & automatic switching for spoofing location parameters and flight guidance modes.
• Automatic start/stop of RF power amplifier; RF output can be switched via external terminal level signal.
