The metal patch was first discovered in 1991 on the atoll, according to TIGHAR, and was placed on Earhart's plane during a stop in Miami in 1937. The Miami Patch was an expedient field repair, Ric Gillespie, executive director of TIGHAR, told Discovery News.
Synthetic vision system. A modern synthetic vision system produced by Honeywell. A synthetic vision system (SVS) is a computer-mediated reality system for aerial vehicles, that uses 3D to provide pilots with clear and intuitive means of understanding their flying environment.
Synthetic Aperture Radar. Security concerns across the global landscape reinforce the need for continuous awareness of oneâs environment. A capability that can provide intelligence imagery anytime, in any type of weather, is critical to enhancing situational awareness and gaining a tactical edge. That capability is Synthetic Aperture Radar, or SAR. Unlike electro-optical imaging systems, SAR is an active system with its own microwave illuminator. Its microwave operating frequencies are chosen so that the radar imaging is unaffected by weather or light. As such, SAR is the only imaging system that can generate high resolution imagery, anytime - even in inclement weather or darkness. Lockheed Martin developed the first operational SAR system in the early 1950s.
