Key field terminal performance requirements

Key Field Terminal Performance Requirements

  • Key performance requirements govern the attributes of the aperture, RF front-end and demodulator

    • “Processing” requirements (e.g., decoding) can be viewed as “functional” requirements

  • LRD Aperture-specific requirements:

    • 1-meter diameter

  • Aperture/RF Front-end requirements:

    • G/T, passband amplitude and phase response (components of implementation loss)

  • RF Front-end/Demodulator requirements:

    • Implementation loss (covering passband response, phase noise, demodulator performance with respect to theory, et al)

  • Link budget entries serve as starting points for these requirement values

    • Requirements are not independent, trade-offs exist

Field terminal software data processor element design

Field Terminal Software Data Processor Element Design

  • Open Systems Group standards compliance at interfaces minimizes configurations

  • Programmable LRD downlink favors 8 Priority EDRs

  • Supports selection of onboard LRD data compression rates by APID

  • Provides flexible ancillary data approach

    • Dynamic ancillary data via satellite downlink to meet System Specification performance

    • NPOESS FT Mission Support Data Server via Internet for increased performance


Fts edr performance

FTS EDR Performance

  • HRD EDR Performance

    • 99% of EDR performance attributes meet or exceed performance thresholds

    • Analysis shows latency requirements achievable with current COTS desktop workstations

    • As with the IDPS software, the FT software adapts to missing channel data or missing ancillary data and uses graceful degradation rules

    • Lossless RICE compression on VIIRS

  • LRD EDR Performance

    • Meets key users’ needs: 0.8 km resolution imagery and programmable downlink

    • Produces the 8 high priority EDRs at or near LRD objective levels

    • Produces all 15 lower priority EDRs and required predecessor EDR products

    • Designed to automatically recognize missing channels and ancillary data

    • Lossless and Lossy JPEG2000 compression on selected APIDs

      • selection of compression level to APID ongoing


Field terminal ancillary data approach

Field Terminal Ancillary Data Approach

  • Dynamic Ancillary Data contained within LRD and HRD downlinks to meet specified performance levels

    • From the NWP Forecast model for six elevation levels at a given geographic location repeated for 12,750 geographic locations around the world

    • LRD Dynamic Ancillary Data within LRD downlink

      • Surface Pressure

    • HRD Dynamic Ancillary Data within HRD downlink

      • Temperature

      • Humidity

      • Surface Pressure

      • Standard Pressure Levels

      • Wind Speed, Wind Direction

      • PrecipitableWater

      • Effective Sunspot Number and Global Geomagnetic Kp for SESS EDR production

  • NPOESS FT Mission Support Data Server via Internet for increased EDR performance

    • Contains full set of Official Ancillary data

    • Contains full set of NPOESS Auxiliary data

    • Contains Community bulletins as to System status

    • Antenna pointing information for signal acquisition


Equal distant data distribution for ancillary data

Equal-distant Data Distribution for Ancillary Data

Equal-distant ancillary data cells provide for efficient data handling and storage:

FT Approach 12,750 cells

Lat/Lon Approach 64,800 cells

Ancillary data cells corresponding to two VIIRS swaths


What is npoess planning

What is NPOESS planning?

  • NPOESS responsible for building software and terminal specifications, but not for building terminals

    • NPOESS will publish specifications and design trade information for users

    • NPOESS will make software available on the program website for download

  • NPOESS will deliver data to users world-wide in accordance with US national data policy

    • Data will be downlinked 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 calls the world-wide users “field terminals” (to differentiate from the Weather Centrals)
