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. 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 the absence of GPS. The INS AN/WSN-12 consists of an Inertial Sensor Module (ISM) and a Navigation Processing Module (NPM) that will provide a significant improvement with respect to attitude and velocity data over previous INS through the use of Power Spectral Density (PSD) capability. PSD provides a tighter tolerance for error across a wider frequency range. The ISM is being designed, developed, and procured through a competitive contract awarded to Northrop Grumman in November 2015. The NPM is a Government design. The government will serve as integration agent prior to the next AN/WSN-12 competitive award scheduled for January 2022. RDT&E funding will support continued system design to create a baseline for Pre-Production Units (PPU), Low Rate Initial Production (LRIP), and Full Rate Production (FRP). 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). Planned FY 2020 efforts include conduct of Physical Configuration Audit (PCA) and completion of logistics documentation. 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 and conduct of cybersecurity risk and vulnerability assessments including development of system models, threat models, and mission models for representative groupings of Navigation systems and cybersecurity capabilities. Risk assessments along with requirements development will lead to incremental capability development leveraging the Increment 1 Engineering Development Model (EDM) delivery with updated architectures and system level modifications. Follow on capabilities will be developed and added to meet existing threats and requirements. Planned FY 2020 efforts include Cross Domain Solution (CDS) and cyber capability Increment 2 development. 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. Planned FY 2020 efforts include development of an Engineering Development Model (EDM). Military GPS User Equipment (MGUE) will provide assured Positioning, Navigation and Timing (PNT) in a GPS degraded environment. Funding will be used for development of interface and performance requirements, shipboard system architecture definition, and MGUE integration into SSNs, Tomahawk, and Advanced Anti-Radiation Guided Missile (AARGM). Planned FY 2020 efforts include early integration with combat/weapons control and other critical systems. Submarine Speed Sensors will provide investigation, development, testing, and integration of new Own-Ship Speed sensors to address new capabilities, reduce detection, and improve reliability. Planned FY 2020 efforts include Environmental Qualification Testing of Doppler sensor. As part of the Future Navy Capability initiative, Assured Positioning, Navigation, and Timing (APNT) funding will be used for Alternate GPS-independent sources of Positioning, Velocity, Attitude, and Timing (PVAT) data required to provide fire control solutions, ensure safety of navigation, and support aircraft and combat operations in a GPS degraded/denied environment. This effort provides a secure navigation method using the Cooperative Engagement Capability (CEC) network and corresponding time and navigation resources being developed via ONR Future Naval Capabilities (FNC) activity. CEC is a critical component of Naval Integrated Fire Control (NIFC) efforts and Integrated Air and Missile Defense (IAMD). Fleet Priority: CEC Non-GPS Aided Positioning for Surface and Submarine (NoGAPSS) addresses 15 Integrated Priorities Capability List (IPCL) Gaps (IAMD 1,4,5,6,7,8,9,10; SUW 1,3,4,6; EW 3; ASW 1,2). As part of the Future Navy Capability initiative, Automated Celestial Navigation System (ACNS) funding will be used for the research, development, Engineering Development Model (EDM), documentation and integration testing of the celestial navigation solution for the No Gaps navigation implementation on the fleet. Efforts will leverage ONR celestial navigation research into a reproducible ruggedized system fully integrated into the navigation suite. FY 2020 efforts include release of development contract. As part of the Future Navy Capability initiative, Navigation Suite funding will be used to conduct analyses and studies on impact of the PVAT Navy Integrating Capability Construct (NICC) to validate, verify and test latency requirements to combat systems consumers. Efforts will include analysis and planning for the alignment and evolution of Afloat Navigation Systems for surface and submarine platforms and 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. Funding will also be used to research and integrate electronic charts into mission planning tools and other combat system elements to provide improved fidelity and commonality among elements and improve navigation awareness in compliance with Navy NAVWAR policies including integration of a Secondary Control Display Unit (SCDU) for the bridge on Surface Platforms. Additional research and integration testing will be conducted for a horizontal plotter display for Navy ECDIS to replace existing chart tables and other navigation oriented tables shipboard.
