The U.S. military is refining an autonomous airdrop system to save thousands of lives and deliver supplies to troops with increased accuracy.

 

Using imagery data, the system has proven able to determine its location based on terrain features, and navigate to a pre-selected position.

 

By making this technology more versatile, troops can be supplied with critical provisions even in high-risk locations.
The U.S. Army's Joint Precision Airdrop System (JPADS) has already proven its importance in supplying troops with necessary materials and equipment, and rely less on convoys.

Truck convoys and helicopters carrying supplies are easily susceptible to ambush, and exposure to improvised explosive devices (IEDs) led to more than 3,000 deaths in Afghanistan and Iraq through 2007, according to Draper.

 

Technological enhancements led by the Army's Natick Soldier Research, Development and Engineering Center (NSRDEC), have made JPADS better equipped for performing in various environmental conditions.

 

The improved JPADS software, by Draper, autonomously flies a cargo-carrying parafoil to a precise location.

 

It applies position, navigation, and timing algorithms to be highly accurate, and adapt to real-time environmental conditions.

 

In recent tests in Arizona, JPADS were dropped from planes, and immediately determined their location using optical sensors to compare local terrain with commercial satellite imagery.

'This is a huge step forward for aerial resupply,' said Chris Bessette, Draper's JPADS programs manager.

 

'The guided airdrop system is keeping U.S. forces from the danger that has killed thousands of their fellow troops.
According to Bessette, accuracy is critical.

 

With investments in increased accuracy, lower cost, and lower retrograde weight and volume of the JPADS, the new version of the system has shown that it can navigate to its intended point, using nothing but imagery to guide it.

The new JPADS also works with little knowledge of the aircraft's location at the point of being dropped.
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 receiver supplies like fuel, ammunition, food, and water in the safest manner possible.'

 

With support from the Army, Draper will continue developments on the system to eliminate current obstacles, like cloud cover, which degrades the vision-aided navigation system's ability to compare vision sensor inputs with satellite imagery.

 

These imagery-data analysis technologies could be used to help guide military free fall paratroopers and autonomous aerial vehicles.
