    1. Global Positioning System (GPS) III Requirements Process 27 Mar 08

    2. Overview What was the process that got us here? How does it all work? What are the current requirements? How do we go forward on GPS III?

    3. What was the process that got us here? The Interagency Requirements Process… Civilian and Military agencies are Part of It We are in this together to make GPS better

    4. Interagency Requirements Process

    5. Example: Geodetic Requirement

    6. GPS III Capabilities Development 2000—Operational Requirements Document (ORD) 2000 Navigation Warfare Analysis of Alternatives (Navwar AoA) 2005—Joint Requirements Oversight Council (JROC) approved initial Capability Development Document (iCDD) Validated GPS III Key Performance Parameters (KPP) for single increment JROC approved US Nuclear Detonation Detection System (USNDS) as payload 2006—JROC approved iCDD addendum Low risk, time-certain Incremental approach (A, B, and C) 2007—JROC approved CDD for Increments A, B, and C Validated requirements for GPS Block III A satellites and Next Generation Control Segment (OCX) Increments I and II Future JCIDS Documents CDDs updated prior to all KDPs for each Increment; CPD prior to each build approval Next CDD update for Increment A KDP-C (2009)

    7. How Does it All Work? All new GPS III requirements were approved by the Interagency Forum for Operational Requirements (IFOR) All requirements included justification and rationale Feasibility, affordability, and best value to government key considerations for approval GPS Wing provides additional cost/benefit analysis Civil requirements should be approved by IFOR prior to commencement of High Performance Team (HPT) Unresolved IFOR issues raised to Interagency Review Board (IRB) for adjudication or to the Interagency Requirements Oversight Council (IROC) if not resolved by the IRB

    8. Requirements Development/Adjudication High Performance Team (HPT) includes civil reps, initially merges requirements for CDD Based on higher level documents (JCD, ICD, CONOPS, etc) Incorporates civil requirements approved via IFOR Civil requirements require appropriate-level approval from within agency Requirements included in CDD based on cost, risk, and operational utility Recommends threshold and objective values and KPPs based on inputs from requesting agency/service All performance values require rationale from submitter CDD coordinated through DoD (AFROCC, FCB, JCB, and JROC) and civil agencies (Ext. DOT Pos/Nav W/G & EXCOM) Unresolved policy related issues can be elevated to EXCOM for resolution

    9. What are the Current Requirements? Selected GPS III A Requirements for the Interagency Backward Compatibility GPS III works with legacy receivers Availability of Position Accuracy Supports military ops, transportation industry, aviation, surveying Position and Time Integrity Essential for safety-of-life applications Time Transfer Accuracy Essential for time-synchronization of numerous military and civil systems GPS/Galileo Interoperability (L1C) International agreements require commonality with Galileo/GLONASS and regional augmentation systems Signal Monitoring Supports safety-of-life applications
