Deeply Integrated GPS/INS Navigation System

Deep integration of GPS and inertial navigation represents a viable option for providing anti-jam (AJ) protection while satisfying size, weight, and power (SWaP) constraints of small-platform applications. QuNav and its subcontractor, Northrop Grumman, propose to prototype and transition a deeply integrated GPS/INS navigation (DIGINAV) system in support of the Navy Warfighter. During Phase I, we developed a software prototype of DIGINAV and demonstrated its AJ capabilities with a) experimental data for a ground test; and b) RF signal simulator data for an unmanned aerial system. Phase II will build on Phase I results to bring DIGINAV to TRL 6 and to prepare it for form-factor prototyping in Phase III and subsequent transitioning. Phase II base effort will fully assemble the enabling techniques developed in Phase I into a reconfigurable architecture of DIGINAV that adaptively selects a deeply integrated configuration to maximize jamming suppression capabilities while enabling best possible PNT performance. A breadboard real-time prototype will be implemented and demonstrated in laboratory environments and then in flight test environments with software injection of jamming sources. Phase II option will perform technology demonstrations in relevant jamming environments (such as NAVFEST) and will develop a form-factor design approach for missionized applications.
