REDSTONE ARSENAL, Ala. -- Positioning, navigation and timing is a critical initiative for the Department of Defense due to an increasing number of GPS threats.

According to Virginia Overstreet, the chief of the Navigation Technology Function at the U.S. Army Aviation and Missile Research, Development and Engineering Center, to address such concerns AMRDEC hosted the second annual PNT Science and Technology meeting April 25-26. The meeting consisted of representatives from various labs to discuss PNT efforts at a DOD level.

Organizations included AMRDEC; the U.S. Army Armament Research, Development and Engineering Center; the U.S. Army's Communications-Electronics Research, Development and Engineering Center; the U.S. Army Night Vision Laboratory; the Air Force Research Laboratory; and the Defense Advanced Research Projects Agency.

"All the labs attending the meeting work on PNT efforts," Overstreet said. "It's really important we share the work we're doing, make sure no one is duplicating work, and we leverage everyone's funding. That's the ultimate goal."

"AMRDEC gained significant insight into the PNT programs across the Army from this meeting, which has allowed us to identify many areas of future collaboration," said Brian Baeder, the Navigation Systems team lead.

The participating organizations briefed their PNT S&T portfolios with the intent of developing collaborative efforts and future roadmaps across labs. On the second day, the event consisted of break-out sessions discussing community initiatives and concerns like inertial sensors, alternate navigation aids and collaborative engagements. The meeting moves location each year so the group can visit different labs and facilities.

"Almost every platform in the Army uses GPS, whether it's for a position solution or a time stamp," said Overstreet. "The wide proliferation of GPS has led to a huge push by the Army S&T community to develop methods for assured PNT during wartime events."

Overstreet expressed while AMRDEC's S&T portfolio solutions are relatively near term, within the next five years, the Center also assists customers that rapidly equip Soldiers in the field. "For AMRDEC, we need our weapons to go where they are supposed to go once they are launched. So having an assured PNT solution is a crucial part of our mission."
