The National Oceanic and Atmospheric Administration (NOAA) is acquiring the next-generation weather and environmental satellite system, named the Joint Polar Satellite System (JPSS). The Suomi National Polar-orbiting Partnership (S-NPP) satellite was launched on 28 October, 2011, and is a pathfinder for JPSS and provides continuity for the NASA Earth Observation System and the NOAA Polar-orbiting Operational Environmental Satellite (POES) system. JPSS-1 is scheduled to launch in early 2017. NASA is developing the Common Ground System which will process JPSS data and has the flexibility to process data from other satellites. This presentation will review the JPSS readiness from a Calibration/Validation perspective. Examples of JPSS Readiness will be presented including algorithm and table updates. The outcomes will show the Cal/Val planning into 2017 for Launch and beyond as JPSS-1 goes into operations.
