Additonal Information: http://www.class.ncdc.noaa.gov/saa/products/search?datatype_family=VIIRS NOAA-20 (JPSS-1) Updated information from ICES for the platform NOAA-20 from US: UNITED STATES. Name : NOAA-20 Country(s) : US: UNITED STATES (ISO Country Code) Platform Class : 65: Orbiting satellite Synonyms: JPSS-1 Commissioned Date : 2018-05-30 Notes : Joint Polar Satellite System (JPSS) is the next generation polar-orbiting operational environmental satellite system series of the USA, and NOAA-20 is the 1st flight unit of the JPSS program, re-named NOAA-20 after the launch. Information Sources: - https://www.nesdis.noaa.gov/content/jpss-series-satellites-noaa-20-spacecraft - https://www.nesdis.noaa.gov/content/jpss-1-mission Comments: Instruments: VIIRS (Instruments ID 218) - Visible Infrared Imaging Radiometer Suite Also known as: JPSS-1 Confirmed by NOAA on 2019-07-12. (FY2019) Submitted to ICES on 2018-11-15. SNPP The NPOESS Preparatory Project (NPP) was renamed to Suomi National Polar-orbiting Partnership (S-NPP) in honor of Verner E. Suomi, University of Wisconsin meteorologist, widely recognized as the "Father of Satellite Meteorology." Suomi NPP is the first next generation polar-orbiting satellite in the JPSS series, and is considered the bridge between NOAA's legacy polar satellite fleet, NASA's Earth observing missions and JPSS constellation. Launched in October 2011, Suomi NPP boasts five state-of-the-art instruments: (1) VIIRS, (2) CrIS, (3) ATMS, (4) OMPS, and (5) CERES FM5— which will be the similar instruments carried on JPSS-1. It has design life of five years and was launched with a Delta-II Mission Launch Vehicle from Vandenberg Air Force Base, California.
