  15. Interface Data Processing Segment • High performance computing hardware • Each Central has a complete system (IDP) that will generate 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 to end users • Centrals have control over what products are created, which ancillary data sets are used, and how products are delivered • Highly automated, fault-tolerant design requires minimal staff • IDPS operator supported by System Administrator ensures proper operations • Cal/Val analyst monitors and validates IDPS products • Same software is used in field terminals • Will be made available worldwide via download from the internet

  16. IDPS Data Delivery • Receives RDRs, TDRs, SDRs, and EDRs from Data Management subsystem • Aggregates and reformats into HDF 5 • Small granules necessary for processing are not seen by external users • Size and delivery frequency of products controlled by external users • Provides products to the Centrals, Cal/Val, ADS/CLASS, and SDS via a file transfer or common disk services

  17. Policy and Planning • NPOESS will deliver data to users world-wide in accordance with US national data policy • Data will be broadcast openly around the world at no cost to receivers • Capability for data encryption/data denial exists for national defense needs • Denial can be done on a world-wide or geographic basis • NPOESS will provide certified data processing software via the Internet to anyone who wishes to use it
