    1. The National Polar-orbiting Operational Environmental Satellite System (NPOESS) Interface Data Processing Segment Field Terminal Segment Gerard Wittman NPOESS Program Manager Raytheon Company October 21, 2004

    2. Concept of Operations

    3. NPOESS Mission Objectives and User Needs Drive System Performance

    4. NPOESS Architecture

    5. Mission Data Flow

    7. Payload Team Summary by Sensor Type and Supplier

    8. NPOESS EDR-to-Sensor Mapping

    9. NPOESS EDR Processing Timeline

    10. Average Data Latency

    11. Mission Data Flow

    12. Interface Data Processing Segment (IDPS) Functional Diagram

    13. IDP Segment Design

    14. IDP Segment Approach High performance IBM computing hardware Each Central has a complete system that generates all products within required latencies Each IDPS or Central contains an Operations string, an Integration and Test (I&T) string, and shared disk arrays (RAID) Operations string carries 100% reserve capacity and additional availability processors I&T string can be used for integration and test of new software, support for technology insertion, parallel operations, failover, and algorithm development Modular, workflow-managed software Receives multiple data streams from C3S, processes data into RDRs, SDRs, TDRs, and EDRs, packages products into form useful for Centrals, and delivers requested products Centrals have control over what products are created, which ancillary data sets are used, and how products are delivered Dual use IDPS core software is also used in field terminals Will be made available worldwide via download from the internet DII-COE, JTA and POSIX standards adherence Careful usage of deployable COTS CORBA ORB, Notification service, naming service, science libraries, HDF5 ARC GIS isolated in DQM which is NOT supported at Field Terminals Single source base
