Satellite

The GOES-16, formerly known as Geostationary Operational Environmental Satellite R Series (GOES-R), is the first of four next-generation geostationary weather satellites being developed by the National Oceanic and Atmospheric Administration (NOAA). The satellite was launched aboard Atlas V 541 rocket from Cape Canaveral Air Force Station in Florida, US, in November 2016.

GOES-16 is placed at 89.5° checkout orbit and operates from either 75° or 137° west position. It is used for detection and observation of environmental phenomena, and weather monitoring over North America.

The four-satellite GOES programme includes R, S, T, and U series, which will extend the availability of the operational GOES satellite system through December 2036.

GOES-16 weather satellite design and development

The GOES-16 spacecraft’s design, construction, and testing contract was awarded to Lockheed Martin. The satellite was co-developed at Nasa’s Goddard Space Flight Center in Greenbelt, Maryland.

The propulsion core module of the spacecraft was delivered to Lockheed Martin in March 2014 and the system module was delivered in April 2014. The system and core modules were mated in September 2014. All environmental, mechanical and electromagnetic tests on the spacecraft were completed by July 2016.

The spacecraft was shipped aboard an Air Force C-5M Super Galaxy cargo transport plane to its Astrotech Space Operations facility in Titusville, Florida in August 2016.

The satellite has exterior dimensions of 6m x 5.6m x 3.9m, a launch mass of 2,800kg, and designed life of 15 years, including ten years of on-orbit operation preceded by five years of on-orbit storage.

Equipment onboard GOES-16 satellite

The GOES-R spacecraft is equipped with six advanced onboard instruments. The advanced baseline imager (ABI) is the primary instrument used for imaging Earth’s weather, oceans and environment. It views the Earth with 16 different spectral bands, including two visible channels, four near-infrared channels, and ten infrared channels.

The geostationary lightning mapper (GLM) instrument is used for the detection of the momentary changes in an optical scene, which can measure total lightning activity continuously over the Americas with near-uniform spatial resolution of approximately 10km.

The solar ultraviolet imager (SUVI), another instrument onboard the spacecraft, is a telescope that monitors the sun in the extreme ultraviolet wavelength range.

The space environment in-situ suite (SEISS) onboard the GOES-R spacecraft consists of four sensors to monitor proton, electron, and heavy ion fluxes in the magnetosphere. The extreme ultraviolet and X-ray irradiance sensor (EXIS) instrument is used for understanding and monitoring solar irradiance in the upper atmosphere.

The GOES-R series satellites are also equipped with a magnetometer (MAG), which provides measurements of the space environment magnetic field.

GOES-16 mission details

"It is used for detection and observation of environmental phenomena and to monitor weather over North America."

The GOES-16 satellite provides images of weather pattern and severe storms as frequently as every 30 seconds. The data provided by the satellite is used to derive accurate and reliable weather forecasts and severe weather outlooks.

The satellite provides data that supports short-term weather forecasts and severe storm warnings, maritime forecasts, and seasonal predictions. Drought outlooks and space weather predictions can also be given with the help of the data.

The satellite is also used for improving hurricane tracking and intensity forecasts, and increase thunderstorm and tornado warning lead time.

GOES-16 launch vehicle details

The GOES-16 satellite was launched aboard Atlas V 541 expendable launch vehicle (ELV) in November 2016. It was lifted off into geosynchronous orbit in two stages.

The launch mission was performed from Space Launch Complex-41 located at Cape Canaveral Air Force Station in Florida.

Ground segment for the GOES-R satellite series

The GOES-16 system is operated from the National Satellite Operations Facility (NSOF) in Maryland and the Wallops Command Data Acquisition Center (WCDAS) in Virginia. The Consolidated Backup (CBU) operations facility for the GOES-16 is located at Fairmont in West Virginia.

Harris Corporation was awarded a ten-year contract to design, develop, test and implement the core functional elements of the GOES-R ground system. The company was also awarded an additional ten-year contract to supply the ground antenna system for the core ground system.

Solers was contracted to provide the environmental satellite processing and distribution system (ESPDS), which is used as GOES-16 Access Subsystem (GAS) in terrestrial, near-real time distribution of higher-order GOES-R products.
