NPP Origins

• NPP is a joint partnership between NASAs Office
  of Earth Sciences (OES) and the NPOESS Integrated
  Program Office (IPO) initiated in 1998
• Feasibility study began in November 1998
• Formulation began in November 1999
• The partnership provides both organizations with
  considerable cost savings while achieving their
  key program objectives
• To provide NASA with continuation of a group of
  global change observations initiated by the Earth
  Observing System (EOS) TERRA, AQUA, and Aura
  missions.
• To provide the NPOESS operational community with
  pre-operational risk reduction demonstration and
  validation for selected NPOESS instruments, and
  algorithms, as well as ground processing.

NPOESS and NPP Mission Deliverables Are Data
Products

• From the System Specification, Appendix A
  Definition/Glossary of Terms
• Raw Data Records (RDRs)
• Full resolution, digital sensor data,
  time-referenced and locatable in earth
  coordinates with absolute radiometric and
  geometric calibration coefficients appended, but
  not applied, to the data. Aggregates (sums or
  weighted averages) of detector samples are
  considered to be full resolution data if the
  aggregation is normally performed to meet
  resolution and other requirements. Sensor data
  should be unprocessed with the following
  exceptions time delay and integration (TDI),
  detector array non-uniformity correction (i.e.,
  offset and responsivity equalization), and
  lossless data compression are allowed. Lossy
  data compression is allowed only if the total
  measurement error is dominated by error sources
  other than the data compression algorithm. All
  calibration data will be retained and
  communicated to the ground without lossy
  compression.
• Sensor Data Records (SDRs)
• Data record produced when an algorithm is used to
  convert Raw Data Records (RDRs) to geolocated,
  calibrated detected fluxes with associated
  ephemeris data. The existence of the SDRs
  provides an intermediate step between the EDRs
  and the raw data. Full resolution sensor data
  that are time referenced, earth (GEO) located (or
  orbit-located for in-situ measurements), and
  calibrated by applying the ancillary information
  including radiometric and geometric calibration
  coefficients and georeferencing parameters such
  as platform ephemeris. These data are processed
  to sensor units (e.g., radar backscatter cross
  section, brightness temperature, radiance, etc.).
  Calibration, ephemeris, and any other ancillary
  data necessary to convert the sensor units back
  to sensor raw data (counts) are included.
• Environmental Data Records (EDRs)
• Data records produced when an algorithm is used
  to convert Sensor Data Records (SDRs) to
  geophysical parameters (including ancillary
  parameters, e.g., cloud clear radiation, etc.).
  EDRs are generally produced by applying an
  appropriate set of algorithms to Raw Data Records
  (RDRs).
•  

23
EDR Requirements are Captured in Appendix D of
the System Spec

• RDR/SDR requirements derive from EDR
  requirements, with specs based on
  modeling/analysis and heritage sensor
  performance, as well as design improvements and
  algorithm developments for NPP/NPOESS

Mission products specified through performance
attributes, associated with remote sensing of
environmental parameters

Attributes are also associated with architecture,
downlink, and processing

NPP Issue Summary

• IEEE 1394 High Data Rate Interface (S/C, VIIRS,
  CrIS)
• Extensive risk reduction program in place
• Recent progress has been very good
• Proof Of Design (POD) chips due end of November,
  2003
• Fight chip sets on track for late January 2004
  delivery
• SDS Requirements Approval
• Current Draft Mission Level 1 Requirements define
  the SDS as research tool (not an operational
  system)
• A study was initiated by the Project/Program for
  an independent assessment of a system
  architecture for NPP climate data needs
• Acceptance and sign-off of the Mission Level 1
  requirements is expected by November

58
NPP Issue Summary

• NOAA NESDIS CLASS (ADS) funding is not sufficient
  to support NPP mission development
• CLASS will not support any of the high volume
  data sets NPP, NPOESS, any of the EOS
  satellites, or GOES-R, at current funding levels
• Currently, CLASS will not achieve readiness to
  support the Oct 2006 NPP launch
• The Assistant Administrator for NOAA's Satellite
  and
  Information Services,
  re-affirmed NOAAs commitment to the ADS and
  promised to find the required resources

S/C CT PT commands

• Provides communications between the NPP
  satellite and the ground through Svalbard and SN.
• Receives stored mission data via X-Band(Svalbard
  only).
• Receives satellite telemetry via S-Band(Svalbard
  SN).
• Transmits satellite commands via S-Band
  (Svalbard SN).
• Performs preprocessing (Reed-Solomon Decoding)
  of SMD telemetry.
• Provide rate buffering of SMD data.
• Provides Monitoring of HRD direct broadcast link
  at Svalbard.

S/C Telemetry

• Provides all inter-segment communications
  between C3S, IDPS, LSS, SDS, and ADS.
• Provides all connectivity between elements
  within the IDPS and C3S.
• Provides command encryption.
• Processes SMD and telemetry VCDUs to generate
  Application Packets for delivery to MMC IDPS.
• Provides data accounting and data recovery.
