Pilots rely on the remote control to establish a connection with the drone and control the flight path. However, the radio signal between the remote control and the drone can be intentionally disrupted, which is commonly referred to as jamming. Frequencies commonly used to jam drones include GPS and various WiFi bands (such as WiFi 2.4GHz, 5GHz, and 5.8GHz).
Jamming involves the deliberate use of transmission blocking signals to disrupt communications between a drone and its pilot.
When a drone is successfully blocked, the following actions can be forced upon it:
- Forced Landing: The drone’s movement is interrupted and it is forced to land at its current location, preventing it from continuing to fly.
- Return to Original Location: If the drone is equipped with GPS and home locator capabilities, it will return to its take-off point in the event of a loss of connection. This is a standard safety feature.
What happens when a drone is blocked? Is it safe?
Jamming is an incomplete countermeasure. It does not provide information about the drone’s intended flight path, nor does it provide information about whether the drone has been programmed to automatically aim for a specific location without interruption. This can be particularly dangerous if the drone is carrying a sensitive payload that could be dangerous in the event of a collision, or if the drone is grounded and approached by security personnel without taking appropriate precautions.
Drone jammers do not locate pilots, determine flight paths, or identify any characteristics of drones or their payloads. They are only designed to interfere with the flight of drones and disrupt their operations.
