Mitigating Drone Interference at Airport Locations

Interfering with Drone Activities in Airport Environments

In terms of jamming, the key factor is power. To put it plainly, if the signals from the pilot and GPS are sufficiently strong for the drone to demodulate and decode them, even amidst the jamming interference, the jamming will not be effective. It is reasonable to assume that any fixed omnidirectional or directional jammer will be deployed on the airfield, with the unauthorized drone pilot likely positioned beyond the airfield's boundaries.

Operating the drone within the airfield perimeter results in a reduction of signal strength from the pilot as the distance increases. Conversely, as the drone draws nearer, the jamming signal's effect on it will escalate.

In this regard, the theoretical performance of jamming is reliant on the position of the uav jammer in relation to the area being covered, assuming an unobstructed line of sight. Nevertheless, as previously indicated, any equipment utilizing the four relevant frequencies will be affected by interference.

Airports can present extensive and often uniquely shaped boundaries. Therefore, when utilizing fixed jammers, including both omnidirectional and directional types, it may be necessary to deploy several units to adequately cover the airport's area. This is a common consideration for all solutions, as they each have specific operational ranges; however, some systems may be more effective by incorporating additional methods. Particularly in larger airports, it is likely that multiple systems will be required to ensure proper coverage of the protected area.

A further alternative is to use targeting jammers in combination with fixed jammers to fill in coverage voids, or, as an exclusive jamming strategy, to utilize a qualified and authorized security or police quick reaction force (QRF).

The design of an airport, featuring runways, taxiways, aprons, peritracks, and access roads, presents notable challenges. The power needed to effectively jam a drone, coupled with the airport's vast size, indicates that the security or police Quick Reaction Force may have to navigate various routes within the airport to establish a position for the jammer gps.

Complicating matters is the drone's unpredictable flight trajectory, which obliges the jammer operator to aim and deploy the jammer at the drone as it nears, irrespective of the angle. Handheld targeting jammers are not akin to lasers with a concentrated beam; they generate a cone of radio frequency energy that can range from around 40° to 90°, potentially disrupting other devices within that cone.
