Research on the Development of a Miniature, Low Power Global Positioning System (GPS)/Inertial Registration Device For Use As A Weapon Orientation Sen

A solution is needed to support training operations in both an outdoor and indoor environment with precise 3-D positioning and weapon orientation to allow geometric pairing. Research solutions are needed to provide a cost effective approach for dealing with this tough problem. Our proposed solution is to leverage an ultra-low power military GPS tracking capability integrated with a low power inertial sensor that can be mounted on a dismounted soldier's small arms weapon. This small, lightweight, low power sensor assembly can be used as an absolute positioning and angular reference for tactical engagement simulation systems during live training exercises and during operational and developmental testing casualty assessment events. Under the Phase I effort we will develop a design concept for the GPS/inertial sensor assembly addressing the partitioning of functionality between the different system components and the security architecture proposed to be applied to allow for P(Y) code signal processing. The final product, under the Phase I effort, will be a report including a system specification with the estimated size, weight, power and wireless interface description for the proposed Phase II prototype units, and the packaging of technologies to support the harsh environments of the military applications.
