Basic principles of GPS decoy technology
The core of GPS decoy technology is to mislead enemy equipment by transmitting fake navigation signals to misposition them.Wifi jammer Usually, these fake signals replace the actual GPS or other navigation satellite signals, making the target equipment mistakenly believe that it is in the wrong location. signal jammer This technology is particularly effective for devices that rely on precise navigation, such as unmanned aerial vehicles (UAVs), because once the UAV is lured away from its set path, its mission will not be successfully completed. cell phone jammer
During the conflicts in Ukraine and Gaza, GPS decoy technology was not only used to interfere with the actions of enemy drones, but was also widely used to protect important facilities from enemy air strikes. GPS jammer By misleading enemy missiles or drones into attacking the wrong coordinates, the defender can effectively reduce the enemy’s attack power without direct engagement.
Challenges and risks of GPS decoy technology
Although GPS decoy technology has shown great potential in military applications, its complex technical settings make it difficult to master and can even cause serious interference to civil aviation if not operated properly. In recent years, commercial aircraft have encountered tens of thousands of interference events each year, some of which have had a substantial impact on the normal operations of airlines. In particular, in a large area from Finland to Egypt, the misuse of GPS decoy technology has caused serious interference to air traffic, which has not only caused economic losses to airlines, but also raised public concerns about aviation safety.
To complicate matters, as technology develops, many modern drones are already equipped with systems that can continue to navigate in the presence of GPS interference. These systems can identify and ignore fake navigation signals, greatly reducing the effectiveness of GPS decoy technology. Therefore, how to design more advanced decoy technology for these high-end drones has become an important direction for future development.
Safran Group and Skyjacker System Rapid Response
Against this background, Safran Group quickly developed the Skyjacker system through its subsidiary Orolia. As a French company specializing in ultra-high precision positioning and navigation, Orolia has deep technical accumulation and industry experience. After acquiring Orolia in 2022, Safran Group used its expertise to complete the development of the Skyjacker system in just six months, demonstrating its rapid response capabilities in the context of the war economy.
The Skyjacker system is able to mislead drones into thinking they are in the wrong location by emitting a modified conical signal to replace the signal sent by the navigation satellite. This system is not only effective against drones piloted by isolated operators, but also protects large areas within a range of 1 to 50 kilometers, guiding drones to the wrong target coordinates, thereby effectively defending against enemy air threats.
