PADS Self-Contained Kit

Calculates wind for precise airdrop release

QinetiQ North America’s PADS, Precision Airdrop System, self-contained kit, calculates wind data used in planning important missions such as free fall parachute navigation and guided airdrop delivery. The data generated is used for defense, foreign aid and military and non-military aircraft (fixed and rotary wing).

The PADS Self-Contained Kit consists of a UHF Dropsonde Receive System, GPS Retransmission System, internal power supply and all of the ancillary hardware to operate on any type of aircraft.  The Kit operates completely independent of aircraft systems (including power) and is housed in a waterproof and shock resistant case that is easily transported.
