NPOESS Goal: Improve the Nation’s Space-Based, Remote Sensing Capabilities for Environmental Monitoring
Sea Surface Temperature (SST)Sea Surface Temperature (SST)
• Sea Surface Temperature is defined as a highly precise measurement of the temperature of the surface layer (upper 1 meter) of ocean water. It has two major applications: 1) sea surface phenomenology, and 2) use in infrared cloud/no cloud decision for processed cloud data. The accompanying requirements apply only under clear conditions (unless specified otherwise).
SSPR ResponsibilitiesSSPR Responsibilities• Government and Contractor Share Risk
- Open Communications Facilitate Insight Into Each Other’s Decisions- Integrated Management Framework (IMF) Improves Visibility
• Large, Flexible Fee Pool- Approaches Commercial Returns- Meet Our Contractors Specific Motivators- Reflects Government Expectations- Success Defined As Meeting Requirements- Incentives Focus on Highest Program Risk -- Total System Integration and
NPOESS Acquisition and NPOESS Acquisition and OperationOperation
• Acquisition and Operation (A&O) Contract was awarded on August 23, 2002 to TRW for $4.5B
• A&O Contract consists of:- 6 satellites- Taking over all government instrument contracts- Buying all “leveraged” instruments- Integrating GFE instruments (ADCS and SARSAT)- Building and deploying all ground systems
• C3 and data retrieval• Data processing hardware and software
- Software for worldwide users
• Operating system through IOC (2011) - With option to 2018
