GOES

Geostationary Operational Environmental Satellites (GOES) circle the Earth in a geosynchronous orbit over the Equator. This means they observe the Earth from the exact same vantage point all the time. This allows the GOES satellites to continuously monitor a single position on the Earth’s surface from 35,800 kilometers (22,300 miles) above the planet. Currently, GOES satellites provide half-hourly observations of the Americas and their surrounding environment.
