EWS-G1

Additional information EWS-G1

DOD-1 (Department of Defense-1) is a weather satellite of the U.S. Air Force, which was 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 April 14, 2010, GOES-13 became the operational weather satellite for GOES-East. It was replaced by GOES-16 on December 18, 2017 and on January 8, 2018 its instruments were shut off and it began its three-week drift to an on-orbit storage location at 60° West longitude, arriving on January 31. 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. GOES-13 was renamed to DOD-1 during the transition.
DOD-1 will become fully operational for the Indian Ocean in mid-2020. NOAA will continue operating DOD-1 on behalf of the U.S. Air Force. The satellite passed through 100 degrees east longitude as of mid-January 2020 and continues moving westward above the Indian Ocean.
