GOES-R and GeoXO Programs

Advanced detection of environmental phenomena that directly affect public safety, protection of property, and our nation’s economic health and prosperity.

The GOES-R and GeoXO Programs manage the development of NOAA’s geostationary satellites, which orbit 22,300 miles above Earth's equator at speeds equal to Earth's rotation. This means that they remain over the same area as the planet spins around its axis. Because they stay above a fixed area on the surface, the satellites provide constant vigil to identify and track severe weather conditions and environmental hazards like fires, smoke, dust storms, fog, and volcanic ash over time. Information from geostationary satellites is primarily used for short-term (1–2 day) forecasts and for tracking storm systems and environmental hazards in real-time.

The GOES-R and GeoXO Programs are collaborative efforts between NOAA and NASA. NASA builds and launches the satellites for NOAA, which operates them and distributes their data to users worldwide. NOAA manages the programs with an integrated NOAA-NASA program office organization, staffed with personnel from NOAA and NASA, and supported by industry.

NOAA’s “R Series” of Geostationary Operational Environmental Satellites (GOES-R) is the Western Hemisphere’s most advanced weather-observing and environmental-monitoring system. The satellites provide real-time, high-resolution imagery and atmospheric measurements of Earth’s weather, oceans and environment, mapping of total lightning activity, and monitoring of solar activity and space weather.

The GOES-R Series is a four-satellite program including GOES-R (GOES-16), GOES-S (GOES-17), GOES-T (GOES-18) and GOES-U (future GOES-19). Each satellite includes a suite of instruments for monitoring weather and hazards on Earth as well as in space. 

NOAA maintains a two-satellite operational GOES constellation, keeping an eye on more than half the globe—from the west coast of Africa to New Zealand and from near the Arctic Circle to the Antarctic Circle. These satellites are known as GOES East and GOES West. 



Three satellites are seen in space hovering over the top half of a full disk satellite image of the Western Hemisphere. The GEO West satellite is on the left and is noted to carry a visible/infrared imager, lightning mapper, and ocean color instrument. The GEO East satellite on the right carries the same instruments. The GEO Central satellite in between East and West is noted to carry a hyperspectral infrared sounder, atmospheric composition instrument, and a possible partner payload.

NOAA’s Geostationary Extended Observations (GeoXO) satellite system will advance observations of Earth that the GOES-R Series currently provides from geostationary orbit. The information GeoXO supplies will address emerging environmental issues and challenges regarding weather, the ocean, and the climate that threaten the security and well-being of everyone in the Western Hemisphere

GeoXO will provide vital information to support short-term forecasts and warnings of extreme weather and environmental hazards as well as long-term planning for the effects of climate change. NOAA plans for GeoXO to improve on GOES-R’s visible/infrared imagery and lightning mapping capabilities. NOAA also plans for GeoXO to add nighttime visible imagery, hyperspectral sounding, atmospheric composition, and ocean color observations. GeoXO observational capabilities are awaiting final program approval. 

NOAA expects that GeoXO will begin operating in the early 2030s as the GOES-R Series nears the end of its operational lifetime.
