Kevlar (para-aramid) is a strong, heat-resistant synthetic fiber, related to other aramids such as Nomex and Technora. Developed by Stephanie Kwolek at DuPont in 1965, the high-strength material was first used commercially in the early 1970s a ...
. It resembled a hobbyist's RC sailplane with a small engine added, with the wing standing up above the fuselage on a pylon and a pusher propeller on the wing behind the pylon. A lithium battery pack powered the UAV's compact electric motor to drive the propeller. The little Pointer was hand-launched. It was recovered simply by putting it into a flat spin, allowing it to flutter down to the ground.
The Pointer carried a
CCD camera fixed in its nose, meaning it had to be directly pointed at its target to see it, which is how the machine got its name. The CCD camera had a resolution of 360 x 380 pixels and a viewing aperture of 22 x 30 degrees. Video could be fed back to the ground station by radio or fiber-optic link.
The ground station recorded flight imagery on an eight-millimeter video cassette recorder. Digital compass headings were superimposed on the imagery and the controller could add verbal comments. The imagery could be inspected with normal, freeze-frame, fast, or slow-motion replay. The aircraft system and the ground control station were carried in separate backpacks. It required a pilot and an observer.
The Pointers in US military service have now been upgraded with a
