JPADS | PRECISION AIR DROP
The Joint Precision Airdrop System (JPADS), combines a steerable parafoil decelerator, controlled by a GPS-equipped autonomous guidance unit (AGU) using advanced navigational control and mission planning software, and powered by an on-board battery pack. Having first obtained its initial position before leaving the aircraft, the AGU then continually updates it by GPS throughout its descent, enabling the load to be manoeuvred very accurately towards its intended landing point. The system can also receive updates en-route.
The JPADS system incorporates internal navigation systems, allowing it to continue travelling with accuracy if a GPS guidance signal is lost.
For small packages, weighing up to 10,000 lbs., JPADS is considered accurate up to 50 metres.
Medium packages, weighing up to 60,000 lbs, are accurate to 75 metres.
Large packages up to 64,000 lbs can, with retrorockets, be carried to an accuracy of 110 metres.
The accuracy of the system allows delivering aircraft to remain at a high altitude to deliver supplies, improving safety for aircrews.
