1 Global Positioning System (GPS) III Requirements Process
27 Mar 08 Lt Col Martin HQ AFSPC/A5P

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? 2 2

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 3 3 3

4 Interagency Requirements Process

5 Example: Geodetic Requirement
Interagency Study Group (NASA, NOAA, NGA, NRL, USNO, USGS) defined GPS III Geodetic Requirement Completed AoA pointing to laser ranging of GPS as optimal solution Requirement and AoA submitted to IFOR – Apr 07 Support letters from NASA and NGA submitted to IFOR – Jul 07 Geodetic requirement accepted by IFOR – 20 Aug 07 GPS Wing tasked with identifying costs/risk/impacts by 1 Jun 08 EXCOM tasked NASA/Air Force (20 Mar 08) to complete compatibility assessment of laser reflectors on GPS by 30 Sep 08 Pending assessment, Geodetic requirement added to GPS III CDD for Increment B

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) GPS III requirements process ensures military and civil requirements properly addressed 6 6

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

10 Notional GPS III CDD Timeline for KDP-C (~Jul 09)
How Do We Go forward on GPS III? Notional GPS III CDD Timeline for KDP-C (~Jul 09) Aug 08 Requirement Strategy Review Aug 08 IFOR Sept 08 High Performance Team (HPT) Dec 08 AFROCC Jan 09 Functional Capabilities Board Jan 09 Joint Capabilities Board Feb 09 JROC Civil Agencies Welcome at Each Event

11 Requirements Process Improvements
AFSPC reorganization designates a single O-6 Command Lead for each capability PNT Capability Team facilitates, coordinates, and synchronizes PNT Issues Improves/restores ability to execute strategic level mission activities Pro-active cross-functional integration Recognized AFSPC focal point Single HQ AFSPC POC for customers, suppliers, mission partners, and HHQ Facilitator, coordinator, synchronizer – not a management layer DOT Liaison at AFSPC coordinates input of civil requirements
