Solar Powered Ground Sensors That Can Transmit Information for Decades

America is supposed to wind down its war in Afghanistan by 2014. But U.S. forces may continue to track Afghans for years after the conflict is officially done. Palm-sized sensors, developed for the American military, will remain littered across the Afghan countryside — detecting anyone who moves nearby and reporting their locations back to a remote headquarters. Some of these surveillance tools could be buried in the ground, all-but-unnoticeable by passersby. Others might be disguised as rocks, with wafer-sized, solar-rechargeable batteries that could enable the sensors’ operation for perhaps as long as two decades, if their makers are to be believed.

The new models are dramatically smaller and consume far less power, enabling them to operate for months — maybe even years — at a time with only the slimmest chance of being detected. Lockheed calls them “field and forget” systems for “persistent surveillance.”

And they won’t just be used overseas. U.S. Customs and Border Patrol today employs more than 7,500 UGSs on the Mexican border to spot illegal migrants. Defense contractors believe one of the biggest markets for the next generation of the sensors will be here at home.

“They could be used for border security or even around corporate headquarters,” Plyburn tells Danger Room.
