NAVSTAR GPS Equipment

Abstract

Navigation Satellite Timing & Ranging (NAVSTAR) Global Positioning System (GPS) project (0921) is a space-based Positioning, Navigation, and Timing (PNT) system that provides authorized users with secure, worldwide, all weather, three dimensional position, velocity, and precise time data. This project is comprised of four distinct efforts: Air and Sea Navigation Warfare (NAVWAR), GPS-based PNT Service (GPNTS), and GPS Modernization. Research, Development, Testing and Evaluation (RDT&E) funds are used to perform all the non- recurring GPS Surface Ship, Submarine and Aircraft Development, Integration, and Testing efforts in support of NAVSTAR GPS. The Air and Sea NAVWAR programs were established to provide continued access to GPS information in a denied or impeded electronic environment. Development efforts for both programs provide improvements to various platform type antennas and ensure compatibility with the new Military Code (M-Code) signal. The Air NAVWAR program continues integration efforts using GPS Antenna System (GAS-1), Advanced Digital Antenna Production (ADAP), and other anti-jam antennas on air platforms while investigating smaller anti-jam antennas for space constrained platforms and aircraft with unique requirements. The Sea NAVWAR program integrates Anti-Jam (AJ) antennas onto surface and subsurface platforms. The Sea NAVWAR program will continue to research the viability and development of smaller anti-jam antennas for space-constrained platforms. The program continues to support the Submarine Anti-Jam GPS Enhancement (SAGE) antenna development which integrates AJ capability into the submarine Multi-Function Mast (OE-538B) antenna system. The GPNTS system is being developed to serve as the primary PNT system for the Navy to ensure reliable PNT capability and interoperability insertion into GPS receivers and associated Command, Control, Computers, Communications and Intelligence (C4I), and Combat Systems in a denied environment. GPNTS provides precise PNT data required for combat, weapons, command, control, communications, navigation, and other systems, as well as providing the time synchronization critical to the network environments. GPNTS will back fit current PNT/GPS systems as well as serve as a forward fit for new platforms. GPNTS will host the GPS Directorate-developed Military GPS User Equipment (MGUE) card, allowing access to the new GPS M-Code signal. GPNTS will provide more robust and secure GPS/PNT capabilities than is currently in the Fleet. The system will provide the capability to migrate non-real time GPS data toward a Common Computing Environment (CCE), such as Consolidated Afloat Networks Enterprise Services (CANES), and provide a path for the integration of advanced navigation systems and sensors. GPNTS supports Anti-Access/Area of Denial (A2AD) by providing Assured PNT (A-PNT) capability to C4ISR and Combat Systems in standalone and networked architectures throughout maritime domains. GPS continues to be integrated in all DoD platforms and the development of enhanced and protected GPS is a national security priority. GPS Modernization executes the Navy's integration of Military GPS User Equipment (MGUE) being developed by the Air Force GPS Directorate. This effort provides Navy platforms improved access to GPS signals in challenged and jamming environments. Because of the number and diversity of all of the Navy's air, surface, subsurface, and weapons platforms, this project will consist of multiple parallel efforts across many program offices with central coordination and management of funding and priorities by GPS Modernization. Modernized GPS receivers will utilize the new M-Code GPS Signal in Space, incorporate enhanced cryptology, deliver greater position and time accuracy, and provide improved protection against signal spoofing as compared to legacy receivers. Additionally, GPS Modernization delivers increased GPS AJ protection and enables blue force GPS electronic attack. This effort supports Navy compliance with Public Law 111-383 which prohibits spending funds on non-M-Code GPS user equipment after FY 2017. Initial NAVSTAR GPS Modernization efforts were funded by the Air Force in FY2015 and FY2016 as a joint effort with the Air Force GPS Directorate--the Department of Defense office for developing military user equipment. FY18 funds provide for Air NAVWAR to ramp up integration efforts and flight testing of anti-jam protection on Unmanned Aircraft Systems (UAS) platforms, for integration of anti-jam antennas into select aviation platforms in order to provide A-PNT in a GPS jamming environment, and for development and integration efforts of miniaturized NAVWAR antennas in AH-1Z, UH-1Y, MQ-4C and MQ-8B/C. Sea NAVWAR funds provide for completion of development and integration of SAGE into the submarine OE-538B antenna system mast, initial government testing of the mast, and research for the development of smaller anti-jam antennas for Size, Weight, and Power (SWaP) restricted platforms. In FY18, GPNTS will ramp up efforts in preparation for Initial Operational Test and Evaluation (IOT&E) to include: coordination with Commander, Operational Test and Evaluation Force (COMOPTEVFOR) and the Joint Interoperability Test Command (JITC) for Combat Systems Certification, Technical Evaluation, and Navigation Certification; prepare pre-test plans, procedures and documentation; complete an Operational Test Readiness Review; and prepare the test platforms. An increase in funds provides for the development of the Pre-planned Product Improvement (P3I) technology insertion for software enhancements for Assured-Positioning, Navigation, and Timing (A-PNT) sensor suite integration and for the design, development, build, integration, and test of a single rack solution for smaller surface combatant platforms. FY18 growth in GPS Modernization funding requirements is due to award of prime vendor GPS integration contracts and procurement of production ready unit (PRU) modernized Military Code (M-Code) capable GPS receiver test articles for the platform integration and test activities of 3 platforms: FA-18E/F, EA-18G, and E-2D, as well as the expansion of GPS Modernization efforts to include the start of government systems engineering and contracting efforts for 5 additional platforms: MV-22, CMV-22, E-6B, CH-53K, and KC-130. Each platform has a unique configuration, which requires separate parallel efforts to integrate and test the modernized GPS receiver into each platform, individual prime vendor contracts, and coordination with each PMA to include management, oversight and support of the effort.
