Israeli firm GPSdome has demonstrated its jam-resistant GPS technology on a small UAV.

The equipment, which weighs less than 6 ounces and uses 0.75 watts of power, was mounted on a small drone from Bluebird Aero Systems.

"We installed our GPSdome on a Bluebird small UAV in order to test its GPS protection during a flight under jamming conditions," GPSdome Chief Technology Officer Moshe Kaplan said in a company news release. "The successful tests showed that the GPSdome-protected UAV continued functioning under jamming attacks and retained its GPS reception, while the unprotected UAV lost the GPS signal."

The company noted that the system would be particularly useful for U.S. Department of Homeland Security border protection drones that face jamming from drug smugglers along the U.S.-Mexico border.
