In response to the evolving security landscape, the fixed navigation deception device represents a groundbreaking innovation specifically engineered to counteract the multifaceted threats posed by unauthorized 'black flying' drones. This sophisticated device emits low-power, regenerated navigation satellite signals that strategically infiltrate the navigation systems of these rogue drones, effectively intercepting and commandeering their flight paths. By doing so, it ensures these drones are prevented from breaching sensitive airspace, thereby safeguarding the low-altitude safety of protected zones. With the capability to replicate satellite navigation deception signals across no fewer than four distinct frequencies, this device executes deceptive interference on the satellite navigation coordinate data received by UAVs reliant on satellite-based positioning. As a result, it adeptly accomplishes critical tactical objectives such as projecting no-fly zones, enabling proactive defense mechanisms, orchestrating directional departures, and executing precise fixed-point deceptions-all essential for maintaining robust aerial security.
