A Tri-agency Effort to Leverage and Combine
Environmental Satellite Activities

• 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

Establishing NPOESS

• National Space Council Study - 1992
• National Performance Review (NPR) - September
  1993
• Identified Need for Coordinated Effort
• OSTP Convergence Implementation Plan submitted to
  Congress - May 1994
• Presidential Decision Directive/NSTC-2 - May 1994
• Directed Convergence of National Assets

• Tri-agency Memorandum of Agreement (MOA) - May
  1995
• Established Roles and Responsibilities of
  Department of Defense, Department of Commerce,
  and NASA
• EUMETSAT/NOAA Initial Joint Polar Agreement -
  November 1998
• Brought in International Community

Two Polar-orbiting Systems

• DMSP (Defense Meteorological Satellite Program)
• Currently
• F-14 Launched December 1994
• F-15 Launched December 1999
• F-16 Planned for Summer 2003

• POES (Polar-orbiting Operational Environmental
  Satellite)
• First Launched April 1, 1960
• Currently
• NOAA-17 Launched Jun 2002
• NOAA-N Launching Fall 2004
• NOAA-N Launching Spring 2006

Evolution
U.S. civil and defense programs, working in
partnership with EUMETSAT, will ensure improved
global coverage and long-term continuity of
observations at less cost!
