US Customs and Border protection is installing an invisible system that will stop drug-smuggling drones from crossing the border from Mexico. The agency signed a contract for over $1M with Citadel who builds systems to counter unmanned flying vehicles. The system deploys a “bubble” around a designated area then uses a monitor to alert the user to drones entering the space. The system uses signals-intelligence and targeted-jamming to stop the drones mid-flight and land them on the ground. The new technology will help protect the border, and if the system is successful the budget for more systems may expand.
