The Athens-Clarke County Police Department was contacted last month by an employee at the U.S. Department of Agriculture research building on College Station Road, to report that a drone was flying over the property without proper authorization.

Police told the employee that she should contact the Federal Aviation Administration to for assistance with deactivating drones flying in restricted areas.

According to published information, here are some techniques that are used by authorized entities like law enforcement and government agencies:

1. Electronic Jamming:

How it works: This involves emitting powerful radio frequency signals at the same frequency used by the drone's remote control, disrupting communication between the drone and its operator.

Outcome: This often triggers the drone's "Return to Home" feature or forces it to land safely, allowing authorities to identify the pilot.

Disadvantages: Can interfere with other radio communication and may not be effective against drones with pre-programmed flight paths.

2. Radio-Frequency (RF) Spoofing:

How it works: This involves sending false signals to the drone's GPS system, tricking it into believing it's in a different location.

Outcome: The drone may fly off course or land in an unexpected area.

Disadvantages: Requires specialized equipment and technical expertise.

Various methods can be used to deactivate drones in restricted airspace. However, it's crucial to understand that using certain methods without proper authorization is illegal for private individuals and can lead to serious consequences, including hefty fines and even criminal charges.
