Drone countermeasures
Hacked off
Guarding against rogue drones could be a legal nightmare
Drone alert
A BLACK package suspended in mid-air under a hovering drone is picked up by the CCTV cameras surrounding Wandsworth prison in south London one evening earlier this year. As it moves closer to one of the windows, a prisoner leans out to snare the delivery with a stick and pull it inside. Prison officers later recover the package and find it is stuffed with drugs and mobile phones.
Such events are becoming increasingly common, not just in the use of drones to deliver contraband but in all sorts of other nefarious activities, from paparazzi spying on celebrities to burglars casing properties. More worrying still are reports of drones being flown near aircraft. Security experts fret about ways terrorists could use drones to drop bombs or biological weapons.
What is needed, many reckon, are drone countermeasures. These already exist for military drones—including shooting them down with lasers. But that is a dangerous way to deal with small consumer drones flying in public areas. So, other answers are being sought in a challenge organised by MITRE, an American non-profit organisation that runs R&D centres funded by the federal government. It has drawn up a list of ten contenders to take part in a trial in August of “non-kinetic” systems capable of detecting and intercepting small drones weighing less than 5lbs (2.3kg). These systems must be good value and capable of wide deployment. The challenge is offering $100,000 of prizes and a chance to catch the eye of federal agencies.
The hurdles posed by the challenge are not what you might expect. “The technology aspects are sometimes the easy part,” says Duane Blackburn, a policy analyst at MITRE. Various rules and regulations mean that interfering with a drone could be a legal nightmare. For example, detecting a small hovering quadcopter drone at any reasonable distance requires a relatively powerful radar. Yet such transmitters are strictly controlled in America under Federal Communication Commission (FCC) regulations, making such equipment difficult and expensive to acquire.
The contenders think they can get around that by detecting the radio communications between a drone and its operator. Although drones can fly independently, some form of radio is used by an operator to relay commands, such as to go up or down, left or right, and to provide a video link from the drone’s camera.
