Global Positioning System (GPS) - Based Positioning, Navigation and Timing (PNT) Service (GPNTS)
Abstract
The GPNTS system is being developed to serve as the primary Assured Positioning Navigation and Timing (A-PNT) system for the surface Navy to ensure reliable PNT capability and interoperability insertion into GPS receivers and associated Command, Control, Communications, Computers (C4) Intelligence, Surveillance and Reconnaissance (ISR) and Combat Systems in a denied environment. GPNTS pairs with AJ antennas and provides precise A-PNT data required for combat, weapons, command, control, communications, navigation, and other systems, as well as providing the time synchronization critical for network environments. GPNTS will back fit current PNT/GPS systems as well as serve as a forward fit for new platforms. GPNTS provides a robust, secure, integrated and interoperable network-centric PNT capability to include: Selective Availability Anti-Spoofing Security Module (SAASM) GPS security architecture; migration path to modernized signal-in-space (M-Code); open architecture approach allowing for the integration of alternate PNT sources; scalable solution that consolidates platform receivers, improved anti-jam and anti-spoof mechanisms; and extended timing holdover in a Global Positioning System (GPS) denied environment. As fielding of the GPS - Based Positioning, Navigation and Timing (PNT) Service (GPNTS) system continues, RDTEN will support product improvements such as the integration of the Office of Naval Research (ONR) developed assured-PNT Future Naval Capability (FNC), Non-GPS Aided Positioning for Surface Ships (NoGAPSS) as well as software enhancements for Assured-PNT sensor suite integration to include Celestial Navigation and Enhanced Assurance Timing (EAT).
