Multi-modal location-aware system for paratrooper team coordination

Navigation and assembly are critical tasks for Soldiers in battlefield situations. Paratroopers, in particular, must be able to parachute into a battlefield and locate and assemble their equipment as quickly and quietly as possible. Current assembly methods rely on bulky and antiquated equipment that inhibit the speed and effectiveness of such operations. To address this we have created a multi-modal mobile navigation system that uses ruggedized to mark assembly points and smartphones to assist in navigating to these points while minimizing cognitive load and maximizing situational awareness. To achieve this task, we implemented a novel beacon receiver protocol that allows an infinite number of receivers to listen to the encrypted beaconing message using only ad-hoc Wi-Fi technologies. The system was evaluated by U.S. Army Paratroopers and proved quick to learn and efficient at moving Soldiers to navigation waypoints. Beyond military operations, this system could be applied to any task that requires the assembly and coordination of many individuals or teams, such as emergency evacuations, fighting wildfires or locating airdropped humanitarian aid.
