The Joint Polar Satellite System (JPSS)

JPSS is the civilian component of the former joint civilian and military National Polar Orbiting Operational Environmental Satellite System (NPOESS) program. After the separation of NPOESS into its civilian and military portions, the National Oceanic and Atmospheric Administration (NOAA) was given responsibility for the early afternoon orbit as JPSS. The Department of Defense, as the Defense Weather Satellite System (DWSS), was given responsibility for the early morning orbit. The separate JPSS and DWSS programs continue to share the Common Ground System for satellite operation and data product processing. Data and imagery obtained from JPSS and DWSS will increase the timeliness and accuracy of public warnings and forecasts of weather events, and will also contribute to the climate data record and climate research. CPI has a small but key role in the development of the Integrated Data Processing Segment (IDPS) of the Common Ground System. CPI’s top contributions to NPOESS/JPSS include: assisting in the program office’s verification of the interfaces between the instruments and the ground data processing software; providing conceptual and technical leadership for the development of IDPS-specific software tools that make development, analysis and maintenance of IDPS algorithm codes much less expensive and time-consuming; providing conceptual and technical leadership for the integration of the IDPS software configuration management between the IDPS developer Raytheon Corp. and the government’s science team and calibration-validation support contractors.
