GOES-19 (designated GOES-U prior to reaching geostationary orbit) is a weather satellite, the fourth and last of the GOES-R series of satellites operated by the National Oceanic and Atmospheric Administration (NOAA). The GOES-R series will extend the availability of the Geostationary Operational Environmental Satellite (GOES) system until 2036. The satellite is built by Lockheed Martin, based on the A2100 platform. The satellite was placed into service as the GOES-East position and GOES-16 was stored as backup on April 7th, 2025.
