Drone Wars

The use of private drones has skyrocketed, yet their owners don't seem to have grasped the serious nature of airspace intrusion over places like airports, nuclear power plants and prisons.
So the gloves are now OFF!

Defence giants Boeing and Lockheed Martin have developed technology ranging from detection systems to more disruptive solutions such as software that forces unauthorised drones to go home or land safely, and laser cannons that shoot unwanted drones out of the sky.
At a demonstration in California, Boeing's compact 2kw laser system took only about 15 seconds to set a drone alight.
Another company has developed software that establishes invisible barriers - "geofences" - around sensitive airspace. When drones hit the virtual boundary, the software overrides the drone's flight controller and forces it to hover. Any drone deployed inside the barrier won't be able to lift off.
It's anticipated the counter-drone industry (both civil and military) could be worth at least several hundred million dollars at this stage, let alone in the future.
Much will depend on how well the technology works. The first step is identifying whether drones are 'friendly' or not. Systems also need to be able to distinguish between slow-moving drones and birds, and the signals from drones compared to cellphones.

It's envisaged that eventually airports, government locations, public swimming pools, defence facilities and the like will all erect "geofences" to inhibit airspace intrusions. Once enough "geofences" intersect, the 'free range' areas for drones will be severely restricted, certainly in cities at least.
So it seems the days of airborne voyeurs roaming wherever they wish via their drones may be coming to an end...
