Precision Airdrop System

In-situ weather information

PADS (Precision Airdrop System) ASonde enables aircrews to obtain in-situ weather information. For guided airdrop systems, the real-time data provided by the PADS ASonde allows mission planners to increase standoff distance and deliver cargo and personnel from higher altitudes with greater precision and safety than conventional methods.

PADS was developed jointly with the U.S. Air Force and the U.S. Army, and designed to meet the demanding requirements of precision delivery of ballistic and guided cargo delivery systems.  The PADS Self-Contained Kit consists of several robust systems needed to operate on a wide variety of aircraft.

• Measurement of real-time information to support guided, ballistic and personnel airdrop operations
