Surface Support

Abstract

The Surface support RDT&E funding will be used for the research, design, development, integration testing, and documentation of a new Inertial Navigation System (INS) AN/WSN-12 for all Navy platforms. Efforts will include analysis and planning for the alignment and evolution of Afloat Navigation Systems for surface and submarine platforms. Development of Capability Phasing Planning (CPP) processes to drive engineering analysis. The program will implement systems engineering processes to investigate major navigation system error sources, define new functions, research new technologies, algorithms, and techniques to improve system performance, conduct analyses of alternatives, create preliminary and final design concepts, develop new hardware components and associated software, and conduct land based and shipboard testing. The INS provides mission critical ship's position and attitude data to shipboard sensors (such as radars), combat systems, gun, and missile systems. The INS uses data from the Global Positioning System (GPS) to periodically update (i.e., reset) its position and internal clock. The INS is the ship's primary position source in absence of GPS. The INS WSN-12 consists of an Inertial Sensor Module (ISM) and a Navigation Processing Module (NPM). The ISM being is designed, developed, and procured through competitive contract award to Northrop Grumman in November 2015. The NPM is a Government design. RDT&E funding will support continued system design to create a baseline for Pre-Production Units (PPU) and Low Rate Initial Production (LRIP). The system will go through Critical Design Review (CDR), Test Readiness Review (TRR), and Production Readiness Reviews (PRR). The system will go through extensive testing including Independent Validation and Verification (IV&V), Developmental Testing (DT) and Operational Testing (OT). Cybersecurity funding will be used for the research, development, documentation and integration testing for cybersecurity hardening and enclave development for navigation systems. Efforts will include the development of boundary defense capabilities, platform specific architectures, Navy-Electronic Chart Display and Information System (Navy-ECDIS) secure solution for existing unclassified configurations and CYBERSAFE implementation. Conduct of cybersecurity risk and vulnerability assessments including development of system models, threat models, and mission models for representative groupings of Navigation systems and cyber security capabilities. The MK27 gyrocompass provides a backup heading reference for SSBNs and LSD platforms and has become obsolete. The AN/WSN-11 (MK27-Replacement) is a form fit function replacement that provides the same functionality while addressing the obsolescence issues of the original MK27. RDT&E funding supports the development, testing and certification of the AN/WSN-11. Military GPS User Equipment (MGUE) to provide assured Positioning, Navigation and Timing (PNT) in a GPS degraded environment funding will be used for MGUE integration into SSNs, Tomahawk, and Advanced Anti-Radiation Guided Missile (AARGM). Development of interface and performance requirements and shipboard system architectures to support MGUE integration. Time and Frequency Distribution System-Replacement (TFDS-R) funding will be used for the research, development, documentation, and integration testing for the Submarine TFDS-R system. TFDS is a Commercial Off the Shelf (COTS) timing system utilizing the precision source signals of GPS to discipline two redundant Rubidium clocks to Universal Coordinated Time (UTC). TFDS provides common time to submarine equipment that utilizes clocking pulses or sinusoidal waveforms for proper operation and maintains accurate time in the event of loss of GPS input (holdover). TFDS Uses multiple input power sources for redundancy and provides a built in battery backup. TFDS generates and distributes Precision Time and Timing Interval (PTTI) reference signals to support C4I capabilities needed for Joint, Naval and Allied missions. This funding will be used to conduct a system level Analysis of Alternatives (AoA) and develop a Technical Requirements Document (TRD). These documents will support detailed analysis of the program implementation strategy to replace obsolete TFDS systems in the Fleet including appropriate documentation and contracting strategies.
