At the moment, in airports all over the world, air traffic controllers sit perched in towers high above the tarmac, keeping an eye on planes on the ground and in the air. But building a tower is expensive—at least building one large enough to house people. So Saab has proposed a considerably simpler structure supporting an elevated platform filled with video cameras that constantly capture a full 360-degree image of the airport. That data, as well as feeds from a controllable zoom camera, can then be fed to a remote location where the video can be projected onto screens surrounding ATC crews.
The technology essentially creates a virtual version of a control tower, except that it's located on the ground, and not necessarily anywhere near the airport it's monitoring. Now, there is always the chance the network connecting the tower to the remote facility could fail, so the idea probably won't be implemented without a reliable backup. But in theory, the tower could be packed with additional technology providing controllers with crystal clear night vision, or even infra-red technologies so they could still monitor aircraft even in a heavy fog. Some terrific innovation, but maybe not the best idea after last year's epidemic of snoozing ATCs. [Smithsonian via BoingBoing]
