  5. 5. Overview Who We Are Constellation Snapshot Milestone Events  Significant Awards/Recognition  IIF  New Signals  GPSOC  New Initiatives  Modernization Efforts 5
  6. 6. Constellation Snapshot 31 Operational Satellites (Baseline Constellation: 24) 10 Block IIA satellites operational 12 Block IIR satellites operational 7 Block IIR-M satellites operational 2 Block IIF satellites operational U.S. Government continuously assessing constellation health to determine launch need  Newest satellites launched  IIR-21 (M)/SVN 50 – 17 August 2009  IIF-1/SVN 62 – 27 May 2010  IIF-2/SVN 63 – 16 July 2011  IIF-3 launch scheduled for Oct 2012 Global GPS civil service performance commitment met continuously since 1993 6
  7. 7. Overview Who We Are Constellation Snapshot Milestone Events  Significant Awards/Recognition  IIF  New Signals  GPSOC  New Initiatives  Modernization Efforts 7
  8. 8. Significant Awards/Recognition GPS Program recognized by the International Astronautical Federation in Oct 2011  One-time 60th Anniversary Award  Recognized GPS as a singular/successful project in the field of Space Applications, Space Science and Exploration, which demonstrates measurable benefit to humanity 2011 Air Force Chief of Staff Team Excellence Award  GPS IIF-1 Total Force (2/19 SOPS, SMC/GP, Aerospace Corp) Satellite Launch and Early Orbit Team  Recognized for 22% increase in manpower efficiency and 60-day redux in launch-to-operational-handover timeline
  9. 9. IIF Satellites On-Orbit IIF satellites launched under SMC/GP Satellite Control Authority (SCA)  Agreement signed between 50 SW/CC and SMC/GP defining roles and responsibilities during the On-Orbit Checkout (OOC) period  SMC/GP retained SCA during OOC with 2/19 SOPS operators  50 SW/CC obtained SCA after OOC completion  L5, L2C, M-Code IIF SV-1 (SVN 62) launched 27 May 10 – available to users on 26 Aug 10  90-day On-orbit Test period  SCA transferred to 50 SW/2 SOPS on 25 Aug 10 IIF SV-2 (SVN 63) launched 16 July 11 – available to users on 14 Oct 11  30-day On-orbit checkout period  SCA transferred to 50 SW/2 SOPS on 19 Aug 11 IIF SV-3 (SVN 65) scheduled to launch NET Oct 12  On-Orbit Checkout projected to last 30 days
  10. 10. L2C and L5 Signals Second civil signal “L2C”  Designed to meet commercial needs  Provides dual-frequency users with a more robust, coded signal to aid in ionospheric correction  All IIR (M) satellites and IIF-1 are broadcasting a developmental L2C signal now  Third civil signal “L5”  Designed to meet demanding requirements for transportation safety-of-life and is available to all users  Uses highly protected Aeronautical Radio Navigation Service (ARNS) band  SVN 62/SVN 63 broadcasting a developmental L5 signal 10
  11. 11. GPSOC DoD’s focal point for operational issues concerning military use of GPS Military applications  Constellation Ops  User Ops • Force location • Navigation DoD’s 24/7 interface to military and civil • Force employment community • Weapon guidance  911 for DoD GPS user emergencies • Satellite positioning • Comm network timing  Supports FAA/NAVCEN in resolving civil user issues Dilution of Precision (PDOP) • Plus Many Others 18 Jan 2008 | Best 4 | Worst Site 10 9.5 PDOP 9 Civilian applications 8.5 8 7.5 7 PDOP >6 = 10 min 17:25Z - 17:34Z 6.5 6 PDOP Value 5.5 5 4.5 4 3.5 • Aviation / Civil Navigation • 3 2.5 2 1.5 Space Shuttle • 1 0.5 0 Search and Rescue 0:00 1:00 2:00 3:00 4:00 5:00 6:00 7:00 8:00 9:00 10:00 11:00 12:00 13:00 14:00 15:00 16:00 17:00 18:00 19:00 20:00 21:00 22:00 23:00 0:00 • Geodetic Measurements Time of Day (Zulu) • Drilling / Mining / Agriculture • Commercial • Plus Many Others 11
  12. 12. New Initiatives Satellite Operations Plans  Developed concise plans for all activities from pre-launch activities to making satellite available to users  Increased efficiency will bring future satellites on-air to users with less risk Satellite Contingency Plans  Developing contingency plans for every satellite currently on-orbit  Most likely failure modes explored with plans to take off the shelf in case of failures  Deliberate forward planning BEFORE an on-orbit emergency happens
  13. 13. Modernization AEP v5.8  Routine sustainment software upgrade  No changes to GPS signal in space – transparent to civilian and military users  Provides C2 of protected receiver capabilities to the JSpOC  Extensive testing conducted – verified no harm to users OCX Buildout  Construction of Next Generation GPS Control Segment began in Mar 12  Scheduled completion of construction NLT July 12  OCX scheduled to be operational 4th quarter 2015
  14. 14. Delivering the Best Space-based PNT  Sustaining capabilities for civil and military users worldwide  Maintain ground systems/on-orbit satellites, launch new satellites  Fielding GPS enhancements  Modernizing constellation with new signals and capabilities  New civil and military GPS signals and control capabilities  Continuing work with international GNSS community  Maintains Backward Compatibility  Managing GPS systems and supporting stakeholdersEstimated US annual economic benefits of 3.3M jobs and $96B for FREE 14
