  2. METOP Tri-agency Effort to Leverage and Combine Environmental Satellite Activities M • Mission • Provide a national, operational, polar-orbiting remote-sensing capability • Achieve National Performance Review (NPR) savings by converging DoD and NOAA satellite programs • Incorporate new technologies from NASA • Encourage International Cooperation NPOESS NPOESS 0530 1330 0930 Local Equatorial Crossing Time

  4. Nunn-McCurdy Certification • Why? Program acquisition cost estimates grew more than 25% above the program of record • By law, required certification to Congress in order to continue the program • Four questions to answer: • Are the requirements valid? • Do alternatives exist for less money and equivalent capability? • Is there a valid cost estimate? • Is there an adequate management structure in place? • Five-month, tri-agency process

  5. Nunn-McCurdy Results • June 5, 2006: Program certified to Congress • Revised program content: Two EMD satellites and two production satellites, in two orbits • De-manifested secondary sensors, kept sensors that satisfied key performance parameters • Continued full-sized bus, preserving ability to add non-manifested sensors if funding becomes available • Provides measured, achievable development timeline

  6. Nunn-McCurdy Results • Requirements revalidated by Joint Requirements Oversight Council, with DOC and NASA representatives • Reduced requirements set for µ-wave imager • Given requirements change, directed that current CMIS procurement stop • Government team will investigate way forward on µ-wave imager • First µ-wave imager targeted for second NPOESS satellite
