industry recognition

“The ability to make the call on hostile intent under the Rules of Engagement is critical. Sagetech’s MX12B micro transponder will go a long way in helping military and troops make the right decisions when it matters the most. This tech will not just enable our forces to prevail in complex multi-domain operations, it will save ‘blue’ lives. Now U.S soldiers, sailors, airmen, marines, and our coalition partners will be able to more readily determine if an inbound drone is friend or foe and take whatever action is needed.
This is a game-changer.”
