EWS-G1 (Electro-optical Infrared Weather System Geostationary) is a weather satellite of the U.S. Space Force, formerly GOES-13 (also known as GOES-N before becoming operational) and part of the National Oceanic and Atmospheric Administration's Geostationary Operational Environmental Satellite system. On 14 April 2010, GOES-13 became the operational weather satellite for GOES-East. It was replaced by GOES-16 on 18 December 2017 and on 8 January 2018 its instruments were shut off and it began its three-week drift to an on-orbit storage location at 60.0° West longitude, arriving on 31 January 2018. It remained there as a backup satellite in case one of the operational GOES satellites had a problem until early July 2019, when it started to drift westward and was being transferred to the U.S. Air Force, and then the U.S. Space Force.
GOES-13 arrived at 61.5° East longitude in mid-February 2020. The satellite was renamed EWS-G1 and became fully operational over the Indian Ocean basin on September 8, 2020. EWS-G2 (GOES-15) was drafted to replace it in September 2023.
EWS-G1 was removed from operational service on October 31, 2023.
