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.

The Navigation Signal Source Module is a satellite navigation signal simulation module developed using satellite signal simulation technology. Operating across the operational frequency bands of GPS, GLONASS, BDS and Galileo navigation systems, it generates real-time simulated signals that perfectly replicate actual satellite signals. This enables applications such as drone navigation spoofing and satellite signal simulation testing, delivering precise navigation deception capabilities for precision targeting operations.

This module transmits deceptive navigation satellite signals designed to mislead drones positioning, navigation, and timing receivers through location spoofing, speed spoofing, and time spoofing. When drones receive these deceptive signals, they will use them to perform positioning maneuvers, enabling multiple deception methods including directional evasion, hovering, rapid crash, controlled landing, and flight prohibition.

The module can be customized according to user needs, and is suitable for petroleum and petrochemical industry, electric power, public security and other fields.

• Be effective to all UAV that relies on navigation satellite positioning system for positioning, the UAVs can be spoofed so as to realize functions such as driving away, heading induction, circular motion, forced landing, flight ban and crash, and can achieve fixed-point forced landing with the assistance of accurate detection equipment;
• Support for global navigation satellite signal system and frequency point simulation, including: BDS, GPS, GLONASS, Galileo, QZSS, IRNSS;
• It has the function of coordinate simulation, which can simulate any coordinates on the ground, and also supports generation of static and dynamic trajectory of points.
• It has the function of receiving navigation satellite signals and time delay compensation, realizes time synchronization with in-orbit satellites, and can adjust channel delay according to the distance to achieve optimal effect, and automatically shield the same frequency interference;
• It has the functions of ephemeris downloading, parsing and storage, update and calculation,etc., so that it can obtain ephemeris in the scene where the satellite signal cannot be received to complete signal simulation as well;
• It can output high precision 10MHz clock signal;
• It has B code/1PPS signal interface, which can grant time to external devices through 1PPS+TOD;
• It has the function of device self-test and abnormal case automatic reporting;
• Provide standard interfaces and protocols to support user development and integration;
• Support customized development of navigation satellite frequency points and functions.
