NOAA-20, designated JPSS-1 prior to launch, is the first of the United States National Oceanic and Atmospheric Administration's latest generation of U.S. polar-orbiting, non-geosynchronous, environmental satellites called the Joint Polar Satellite System.

The Visible Infrared Imaging Radiometer Suite (VIIRS) is one of the key instruments onboard the NOAA-20 spacecraft. It collects visible and infrared imagery and global observations of land, atmosphere, cryosphere and oceans.

2025年2月27日 · VIIRS is one of the five key instruments onboard NOAA-20 that will improve day-to-day weather forecasting and environmental monitoring, while extending the record of many long-term observations of Earth's climate.

The five satellites scheduled in the fleet are the currently-flying NOAA/NASA Suomi National Polar-orbiting Partnership (Suomi NPP) satellite, NOAA-20, previously known as JPSS-1, NOAA-21, previously known as JPSS-2, and the upcoming JPSS-3 and JPSS-4 satellites.

JPSS-1 launched into space on November 18, 2017 and it is the first spacecraft of NOAA's next generation of polar-orbiting satellites. JPSS-1 was renamed NOAA-20. Capitalizing on the success of Suomi NPP, NOAA-20 features five similar instruments: (1) VIIRS, (2) CrIS, (3) ATMS, (4) OMPS-N, and (5) CERES-FM6.

National Oceanic and Atmospheric Administration - 20 | 1st flight unit of the JPSS programme, re-named NOAA-20 after the launch. Main mission: operational meteorology. Substantial contribution to atmospheric chemistry and climatology.

2022年10月11日 · The third satellite in the series, NOAA-21 (formerly JPSS-2), launched November, 10, 2022. Once it reached its polar orbit JPSS-2 was renamed NOAA-21. Once NOAA-21 is fully commissioned and science products are provisional, notionally a year after launch, NOAA-20 will transition a quarter orbit ahead of S-NPP.

2017年11月18日 · The Joint Polar Satellite System-1 (JPSS-1), or NOAA-20, is the second spacecraft within the National Oceanic and Atmospheric Administration's (NOAA's) next generation of polar-orbiting satellites. Capitalizing on the success of the Suomi National Polar-orbiting Partnership (NPP) satellite, the JPSS-1 spacecraft boasts five similar instruments ...

NOAA-20（NationalOceanic and Atmospheric Administration20）是美国国家海洋和大气管理局（NOAA）于2017年发射的一颗极轨道卫星。 它是JPSS（JointPolar Satellite System）的一部分，旨在提供高质量的气象和环境数据。

2018年5月31日 · NOAA-20, the first of four in the NOAA’s next generation Joint Polar Satellite System (JPSS) series, was declared operational today by the agency’s top officials. Launched last November as JPSS-1 and renamed NOAA-20 upon reaching its final orbit, the advanced satellite cleared a rigorous test phase of its instruments and data systems.
