NPP Mission Segment (1 of 2)
Space Segment (SS): The NPP Space Segment (SS) consists of the satellite and ground test support equipment. The satellite is comprised of the BCP 2000 bus and the following instruments:
Visible-Infrared Imager Radiometer Suite (VIIRS), Cross-Track Infrared Sounder (CrIS) Ozone Mapping Profiling Suite (OMPS), Advanced Technology Microwave Sounder (ATMS).
Command, Control, and Communications Segment (C3S): Provides the NPP satellite operations capabilities, communication routing of mission data and the ground receive station, overall mission management, and coordinating the joint program operations needs.
Interface Data Processing Segment (IDPS): Pre-processes Stored Mission Data, process and generates Raw Data Records (RDRs), Sensor Data Records (SDRs) and Environmental Data Records (EDRs) for subsequent transfer the the NOAA CLASS and Weather Prediction
rev 25-Aug-2008 CERES dCDR – 20
NPP Mission Segment (2 of 2)
Archive and Distribution Segment (ADS): The main function of the ADS is to receive and archive RDRs, SDRs, and EDRs from the IDPS. xDRs are archived, as are the associated metadata, upon which users may
search, browse, and order data.
Launch Support Segment (LSS): The LSS provides those assets and services associated with the launch vehicle (LV) and the payload integration.
– This segment includes all ground support equipment, property, and facilities to integrate the spacecraft to the LV, verify their integration, and conduct pre-launch testing with the remainder of the ground system..
• Science Data Segment (SDS): The SDS is a prototype element of the future NASA Earth Science Enterprise distributed science data system.
– The role of the NPP SDS is limited to assess the quality of the NPP EDRs for accomplishing climate research.
