IDPS Goals - NPP Risk Reduction

• IDPS Risk Reduction
• Early delivery and prototype-operational test of
  NPOESS ground data processing system architecture
  and components
• Early user evaluation of NPOESS data products
• Provides algorithm/sensor verification and
  opportunities for sensor calibration/validation
• VIIRS makes primary contributions to 26 of 61
  EDRs
• CrIS/ATMS makes primary contributions to 3 of 61
  EDRs
• Allows for algorithm modifications prior to C1
  launch
• Provides opportunities for prototype utilization/
  demonstration of NPOESS imager sounder products

External Interfaces

• Ancillary Data Systems
• Receive data from other systems outside of the
  NPP scope that is required for performing the
  processing within the IDPS e.g. Digital
  Elevation Models

NPOESS Acquisition Strategy

• NPOESS space ground system segments will be
  acquired in two major phases
• Phase I - Program Definition Risk Reduction
  (PDRR) Ground System Demo and Prototype
• Contract awarded in December 99 (Multiple
  awards)
• Phase II - Engineering and Manufacturing
  Development (EMD)
• NPOESS Prime Contractor award projected for April
  02 (Single award)

Program
Definition and Risk Reduction (PDRR)

• PDRR Contract Focus
• Defining IDPS External Interfaces
• End-to-End Processing Demonstration
• Allows users early access to simulated data for
  planning purposes
• Overall ground data processing system
  architectures and trades
• Efficient, Flexible and Modular to allow for
  future upgrades
