NOAA maintains a two-satellite Geostationary Operational Environmental Satellite (GOES) constellation to watch over the Western Hemisphere. The satellites circle the Earth in geosynchronous orbit, which means they orbit the Earth’s equatorial plane at a speed matching the Earth’s rotation. This allows them to stay in a fixed position in the sky, remaining stationary with respect to a point on the ground.
GOES-16 serves at as NOAA’s GOES-East satellite, located at 75.2 degrees west longitude. GOES-S, GOES-16’s sister satellite, scheduled for launch in March 2018, will be renamed GOES-17 upon reaching geostationary orbit. GOES-17 will take its place as NOAA’s operational GOES-West satellite in late 2018. In the GOES-West position, GOES-17 will be located at 137 degrees west longitude. Together, GOES-16 and GOES-17 will keep an eye on the Western Hemisphere’s atmosphere, weather patterns and environmental hazards from the west coast of Africa all the way to New Zealand.
