Field Terminal Segment Changes • NOAA/NESDIS/IPO contractor will only be delivering operational HRD and LRD Algorithms • NOAA/NESDIS/IPO will have a demonstration terminal that will process NPP HRD with IPOPP • Will only support IBM AIX Operating System • Retained Original LRD baseline design on NPOESS – Using JPEG-2000 Lossy Compression • Will monitor HRD and LRD downlinks at Svalbard

Field Terminal Segment - What Changed? Legend Satellite Down Link Field Terminal Data Flow Optional FT Data Flow NPOESS / NPP Satellites Mission and Ancillary Data (HRD/LRD Downlink) NGST Developed Removed NOAA TOC Satellite-SPE Interface Mission Support Data Server (C 3 S) Mission Status Data FT Interfaces • Ancillary Data (NCEP-GFS, FNMOC-NOGAPS, NISE) • Auxiliary Data • TLE FT-MSDS Interface (Optional) Satellite SPE Interface External-Data Source FT - TOC Interface (Optional) Field Terminal Segment Data Processor Element (DPE) Signal Processing Element (SPE) • Antenna / RF Processing • GPS and Timing • Satellite Scheduler • CCSDS Processing FT Operator - Mission Data - Mission Support Data - Satellite Pass Storage - TLE Extraction • Decryption (optional) Optional FT Interfaces SPE-DPE Interface Streaming APs • DPE Hardware - Processing - Storage > Mission Data FT Operator > Mission Support Data > Static Data • DPE Software - ING, PRO, INF, DMS, DDS Mission Application Element (MAE) DPE-MAE Interface • User-defined HDF Product Display FT Operator or User Product requests & HDF files
