NOAA climate satellite tv for pc transitions to new position for U.S. army – Spaceflight Now

A climate satellite tv for pc constructed and launched for NOAA in 2006 to assist observe hurricanes approaching america has been repositioned to observe climate situations within the Center East to help U.S. army operations within the area.

The GOES-13 satellite tv for pc, not wanted for monitoring climate over america, was transferred from NOAA to the U.S. Air Power final yr underneath an interagency settlement. The House Power’s House and Missile Techniques Heart introduced Sept. eight that the spacecraft has arrived and commenced operations at a brand new location in geostationary orbit over the Indian Ocean.

The spacecraft has been renamed the Electro-optical Infrared Climate system Geostationary 1, or EWS-G1, spacecraft.

The EWS-G1 spacecraft is the primary geostationary climate satellite tv for pc owned by the Division of Protection, the House Power mentioned in an announcement. “The satellite tv for pc supplies well timed cloud characterization and theater climate imagery to DoD within the Indian Ocean area, addressing wants throughout Central Command and different working theaters,” the army mentioned.

Central Command oversees U.S. army operations within the Center East and elements of Central Asia, together with Afghanistan and Iraq.

The House and Missile Techniques Heart mentioned the switch and relocation of the newly-renamed EWS-G1 satellite tv for pc was the fruits of joint efforts between the House Power, NOAA, and NASA.

Launched from Cape Canaveral aboard a Delta four rocket in 2006, the GOES-13 satellite tv for pc grew to become the first climate observatory in NOAA’s GOES-East location in 2010. From a perch greater than 22,000 miles (almost 36,000 kilometers) over the equator, GOES-13’s imager and sounder devices tracked tropical cyclones within the Atlantic Ocean, Gulf of Mexico, and Caribbean Sea, and monitored extreme climate, snowstorms and, different climate programs throughout the japanese half of america.

In geostationary orbit, satellites transfer round Earth on the identical fee the planet rotates. Such orbits are helpful for communications satellites and climate observatories, giving spacecraft fixed protection over the identical a part of the planet.

GOES-13 was the primary in a collection of three NOAA geostationary climate satellites constructed by Boeing that launched in 2006, 2009, and 2010. Regardless of struggling issues with its photo voltaic imager and sounder, GOES-13 remained in service supplying imagery to climate forecasters till the extra succesful GOES-16 satellite tv for pc took over the GOES-East place in December 2017.

NOAA then moved GOES-13 to an on-orbit storage location till the satellite tv for pc was transferred to the army in 2019.

“EWS-G1 is a major instance of innovation and the leveraging of partnerships. SMC partnered with NOAA and NASA to ship critically wanted geostationary seen and infrared cloud characterization and theater climate imagery within the Indian Ocean area,” mentioned Charlotte Gerhart, chief of the House and Missile Techniques Heart’s manufacturing corps low Earth orbit division.

“This effort demonstrates pace by permitting the spacecraft to be moved and operated within the Indian Ocean area far sooner than a brand new satellite tv for pc might be produced and fielded,” Gerhart mentioned in an announcement. “The repurposing of GOES-13, and residual NOAA floor gear, achieved the mission at a fraction of the procurement price of a model new system.”

NOAA will proceed working the EWS-G1 satellite tv for pc on behalf of the House Power for its remaining life span from the company’s operations facility in Suitland, Maryland.

After arriving at its new working location, the satellite tv for pc was put by means of a “thorough checkout” of its spacecraft and sensor programs, the House Power mentioned.

Earlier than taking up the GOES-13 satellite tv for pc to turn out to be EWS-G1, the army used climate imagery from the European Meteosat eight satellite tv for pc positioned in geostationary orbit over the Indian Ocean. Meteosat eight is anticipated to expire of gasoline round 2022.
