Technology Inside Drone
UAVs operate in the world of tactical intelligence, surveillance and reconnaissance or ISR, generally providing immediate support for military operations often with constantly evolving mission objects. Traditionally, airborne ISR imaging systems were designed around one of two objectives, either looking at a large area without the ability to provide detailed resolution of a particular object or providing a high resolution view of specific targets, with a greatly diminished capability to see the larger context. Up until the 1990s, wet film systems were used on both the U2 and SR-71. Employing a roll of film 12.7 cm or 5″ wide and almost 3.2 km or 2 miles long, this system would capture one frame every 6.8 seconds, with a limit of around 1,6000 frame captures per roll.
