Non-GPS Autonomous Aerial Delivery

The U.S. Army’s Joint Precision Airdrop System (JPADS) has developed a new capability with a navigation alternative to GPS. In recent tests, JPADS were dropped from planes, and immediately determined their location using optical sensors to compare local terrain with commercial satellite imagery. The new system demonstrated navigation to its intended point, using nothing but imagery to guide it.

JPADS, largely guided by GPS, has already proven its importance in supplying troops with necessary materials and equipment, relying less on vulnerable convoys. However, the new JPADS also works with little knowledge of the aircraft’s location at the drop point.

Dropping critical supplies from the air has allowed the U.S. military to rely less on easily-ambushed truck convoys and helicopter resupply. Exposure to improvised explosive devices (IEDs) and ambushed convoys resulted in more than 3,000 causalities in Afghanistan and Iraq through 2007.

JPADS has proven to be an important tool in the Army’s logistics chain in many scenarios to supply troops with material and equipment in adverse terrain and remote locations when ground lines of communication are not possible or deemed too high a risk.

“This is a huge step forward for aerial resupply,” said Chris Bessette, Draper’s JPADS program manager. “By enabling the system to operate using imagery alone when dropped as high as 25,000 feet above Mean Sea Level and upwards of 20 miles away from the target depending on winds, we can ensure that JPADS is even more versatile so troops receive supplies like fuel, ammunition, food, and water in the safest manner possible.”
