GOES-R Series Satellites Spacecraft and Instruments

 

THE INSTRUMENTS

Advanced Baseline Imager (ABI)​

ABI is the primary instrument on the GOES-R Series for imaging Earth’s weather, climate, oceans and the environment. ABI views the Earth with 16 spectral bands (compared to five on previous GOES) and provides three times more spectral information, four times the spatial resolution, and more than five times faster coverage than the current system.

Geostationary Lightning Mapper (GLM)

Geostationary Lightning Mapper (GLM)

GLM is the first-ever operational lightning mapper flown in geostationary orbit and measures total lightning (in-cloud and cloud-to-ground) activity. Developing severe storms often exhibit a significant increase in total lightning activity, and data from the GOES-R Series lightning mapper has great potential to increase lead time for severe thunderstorm and tornado warnings.  Click here for more information about GLM.

Extreme Ultraviolet and X-ray Irradiance Sensors (EXIS)​

Extreme Ultraviolet and X-ray Irradiance Sensors (EXIS)​

EXIS detects and monitors solar irradiance in the upper atmosphere. The X-Ray Sensor monitors solar flares that can disrupt communications and degrade navigational accuracy, affecting satellites, astronauts, high-latitude airline passengers and power grid performance. The Extreme Ultraviolet Sensor monitors solar variations that directly affect satellite drag and tracking and ionospheric changes, which impact communications and navigation operations.

Solar Ultraviolet Imager (SUVI)​

Solar Ultraviolet Imager (SUVI)​

SUVI is a telescope that observes and characterizes coronal holes, solar flares and coronal mass ejection source regions. SUVI data enables improved forecasting of space weather and early warnings of possible impacts to the Earth environment, including disruption of power utilities and communication and navigation systems as well as possible damage to orbiting satellites and the International Space Station. Click here to for more information about SUVI.

Magnetometer (MAG)

MAGNETOMETER (MAG)

The Magnetometer provides measurements of the space environment magnetic field that controls charged particle dynamics in the outer region of the magnetosphere. These particles can be dangerous to spacecraft and human spaceflight. The geomagnetic field measurements provide alerts and warnings to satellite operators and power utilities.

Space Environment In-Situ Suite (SEISS)

Space Environment In-Situ Suite (SEISS)

SEISS is an array of sensors that monitor proton, electron and heavy ion fluxes at geosynchronous orbit. Information provided by SEISS is used for assessing radiation hazards to astronauts and satellites and to warn of high flux events, mitigating damage to radio communications.  Click here to read more about SEISS.

The Spacecraft

A GOES-R Series Satellites Spacecraft Illustration

The Launch Vehicle that will place the GOES-16 into geosynchronous orbit will be an Atlas V 541. The three numbers in the 541 designation signify a payload fairing, or nose cone, that is approximately 5 meters (16.4 feet) in diameter; four solid-rocket boosters fastened alongside the central common core booster; and a one-engine Centaur upper stage.

A launch vehicle is chosen based on how much mass the vehicle can lift into space. A two-stage Atlas V 541 launch vehicle was selected for the GOES-16 launch because it has the right liftoff capability for the heavy weight requirements.
