A-PNT, or assured position, navigation, and timing, is a relatively new buzz phrase in military navigation systems. It enhances existing selective availability anti-spoofing module (SAASM) GPS navigational technologies (which are already immune to spoofing) with other PNT methods that are not susceptible to signal loss, jamming or satellite destruction. A-PNT’s lofty goal is to give soldiers the ability to identify and communicate accurate location, course, and time without countermeasure interference.

ORLANDO, Fla. The Direct Attack Guided Rocket (DAGR) from Lockheed Martin tracked and engaged a moving target from 3.5 kilometers during an Apache helicopter demonstration at Yuma Proving Ground, Ariz. Test pilots on an AH-64D Apache shot an inert DAGR round in high winds, designating the target via the helicopter’s lock-on-before-launch mode. The target -- a truck – was moving at 25 miles per hour.
