  1. Evolving Ground Systems Architecture Requirements for the National Polar-orbiting Operational Environmental Satellite System (NPOESS)International Geoscience and Remote Sensing Symposium IGARSS 2002 24th Canadian Symposium on Remote SensingJames L.

  2. Evolving Ground System Architecture Requirements for the National Polar-orbiting Environmental Operational Satellite System (NPOESS)

  3. NPOESS NPOESS is required to provide anoperational remote sensing capability to acquire and receive in real-time at field terminals, and to acquire, store and disseminate to processing centers,globaland regional environmental imagery and specialized meteorological, climatic, terrestrial, oceanographic and solar-geophysical and other data in support of civilianand nationalsecurity missions

  4. NPOESS Mission A Tri-agency Effort to Leverage and Combine Environmental Satellite Activities Mission Provide a national, operational, polar-orbiting remote-sensing capability Achieve National Performance Review (NPR) savings by converging DoD and NOAA satellite programs Incorporate new technologies from NASA Encourage International Cooperation Local Equatorial Crossing Time NPOESS-Lite

  5. NPOESS Requirements Solar Geophysical Oceanographic Atmospheric Terrestrial Climatic Disaster Planning Ocean Navigation Disaster Response IORD-II: 55 Data Products 21 Enhancement Products

  7. NPOESS Unaccommodated Environmental Data Records EDRs not Addressed by Notional NPOESS System Pre-Planned Product Improvement (P3I) • Tropospheric winds - CH4 (methane) column • CO (carbon monoxide) column - CO2 (carbon dioxide) column • Optical backgrounds - Bathymetry • Potential Bioluminescence - Salinity • All Weather, Day/Night Imagery (High Res) • Littoral Currents - Coastal Ocean Color • Coastal Sea Surface Temp - Coastal Sea Sfc Winds/Wind Stress • Coastal Sea Surface Height - Ocean Wave Characteristics • Surf Conditions - Oil Spill Location • Vertical Hydrometer Profile - Sea and Lake Ice • Neutral Winds - Coastal Imager IORDI IORDII P3I EDRs Increased to 21 in IORD II

Centrals: NOAA/NESDIS AFWA FNMOC, NAVO NPOESS Baseline Architecture Space Segment DomSat 0530 1330 NPP 1030 NPOESS lite 0930 METOP Mission Data Launch Support Segment Cmd/Tlm/Status & Mission Data IDP Segment (RDR, SDR, EDR) Direct Broadcast Cmd/Tlm/Status C3 Segment McMurdo/ Svalbard DoD/Non-DoD/DoC Field Terminals CDA MMC (Schriever AFB) MMC (Suitland MD) Fairbanks Tlm/Status

  9. 2008 - 2018+ Data Rates • Today we process <1 Mbps (DMSP & POES) • In 2005/8 NPP/NPOESS will process 20 Mbps • Tropospheric Wind Lidar remote sensing from space could add another 10 Mbps • SARs could add 600+ Mbps peak data rate • Provide soil moisture profiles • Coastal sea surface height, temperature, winds • Near shore bathymetry • Coastal Imagery • Surf conditions (surf zone, breaking waves, currents) • Ocean Salinity

  10. Future Ground Systems -- 2025 • Potential Orders of Magnitude Increase in Data Rates • Higher demand for reduced latency • Flexible NPOESS Ground Systems Architecture in place • Additional non-NPOESS Demand for monumental volumes of data processing (from multiple sources) • Geostationary, L-1 and L-2 sources • Ground system sources -- radar, in situ, et al. • Low earth orbit systems (other than NPOESS) • Global Precipitation Mission (NPOESS partial element) • Increased ship-based measurement sources • NASA web of sensors concept fulfills this need NPOESS on the Web -- http://npoess.noaa.gov
