About 2.5 seconds after the launch of STS-114, the first Return to Flight launch after the Columbia accident, a large bird struck the external tank and fell into the exhaust plume. While this particular bird strike did not threaten the vehicle because it did not strike the orbiter, it did raise awareness of the threat of avian fauna present at launch. In response to the avian threat, a Bird Radar system was developed to detect birds above the launch pad. Because of interference with launch systems, the radar system could not span closer than a few hundred feet above the pad. There was a gap region that would not be visible with the radar.
The Bird Vision System consists of four separate software applications: Bird Vision Overlay, Acquire and Process Images, Bird Vision Overlay Remote, and Bird Vision Playback. The system, in its current implementation, consists of four networked computers. Two computers are dedicated to one camera each. One machine connects both to a camera and serves as the central server. One remote viewing machine resides in the Kennedy Space Center Launch Control Center (LCC) room console.
The system is much less expensive and less intrusive than traditional radar systems, and can be adapted to virtually any viewing scenario and used with virtually any video sources. It operates semi-automatically; operators only need to supervise and ensure data integrity. Real-time results can be viewed from a virtually unlimited number of independent stations on the local network.
