Joint Precision Airdrop System
The Joint Precision Airdrop System (JPADS) is an American military airdrop system which uses the GPS, steerable parachutes, and an onboard computer to steer loads to a designated point of impact (PI) on a drop zone (DZ). It integrates the US Army's Precision and Extended Glide Airdrop System (PEGASYS) and the Air Force's Precision Airdrop System (PADS) program. PEGASYS consists of several precision airdrop systems, ranging from extra light to heavy payloads, while PADS resides on a laptop which computes the release points for non-steerable parachute systems by means of software capable of mission-planning, weather forecasting, and current measurements of wind velocity, altitude, air pressure, and temperature. It can also receive weather updates and en route mission changes through satellite links.
==History==
US Army Research, Development and Engineering Command (RDECOM) was the primary developer for JPADS, which meets several requirements: increased ground accuracy, standoff delivery, increased air carrier survivability, and improved effectiveness/assessment feedback regarding airdrop mission operations. The United States Army and Air Force began jointly developing this system in 1993. The Air Force made its first operational/combat use of the system in Afghanistan in 2006.
