System-Of-Systems Open Architecture PNT (SOAP) Solution for Assured PNT in a GPS Denied Environment

Currently PEO U&W programs rely on GPS/inertial navigation systems to provide Positioning, Navigation and Timing (PNT) solutions. These systems cannot support precision navigation if GPS denied for extended periods. NAVSYS proposes to provide an innovative system-of-systems, open architecture PNT (SOAP) solution that will enable the Navy to take advantage of new augmentation signals and next generation sensors to provide precision, Assured PNT (A-PNT) in the absence of GPS. Under the proposed Phase II base effort we shall build two SOAP Test-Beds to demonstrate a back-up PNT capability using a commercial Software Defined Radio (SDR) integrated with our inertial InterNav® software product. Testing will be performed using commercial satellites as signals of opportunity (SoOP) to provide a Global Military Positioning Service (GMPS). The SOAP Test-Beds will be used to demonstrate PNT operation in a completely denied GPS environment and provide recommendations on how the SOAP A-PNT services could be integrated into next generation tactical radios. Under the proposed Phase II Option we shall develop a SOAP A-PNT design that is compatible with an open architecture environment selected for future tactical radios in weapons and unmanned systems and we shall demonstrate the SOAP software running as a prototype open architecture A-PNT service.
