Polar-Orbiting Environmental Satellites: Changing Requirements, Technical Issues, and Looming Data Gaps Require Focused Attention
David A. Powner (au)
Environmental satellites provide critical data used in forecasting weather and measuring variations in climate over time. The Nat. Polar-orbiting Operational Environmental Satellite System (NPOES -- a program managed by the Nat. Oceanic and Atmospheric Admin. (NOAA), Dept. of Defense (DOD), and Nat. Aeronautics and Space Admin. (NASA) -- was planned to replace two existing polar-orbiting environmental satellite systems. However, 8 years after a development contract for the NPOESS program was awarded in 2002, the cost estimate had more than doubled ńˇţ to about $15 billion, launch dates had been delayed by over 5 years, significant functionality had been removed from the program, and the programńˇ╗s tri-agency management structure had proven to be ineffective. In Feb. 2010, a presidential task force decided to disband NPOESS and, instead, to have NOAA and DOD undertake separate acquisitions. This report evaluates (1) efforts to transfer responsibilities from the NPOESS program to the separate NOAA and DOD programs, (2) NOAAńˇ╗s progress in developing its satellite system, and (3) NOAAńˇ╗s efforts to mitigate key project risks. Tables and figures. This is a print on demand report.
