GOES-16 Engineering Breakdown

GOES-16 introduced a new generation of U.S. geostationary environmental observation. Launched as GOES-R in November 2016 and renamed GOES-16 after reaching orbit, it became the operational GOES-East satellite on 18 December 2017. From geostationary orbit it supplied rapid, continuous views used to monitor hurricanes, severe storms, lightning, clouds, smoke, fires and other hazards across much of the Western Hemisphere. GOES-19 replaced it as GOES-East on 7 April 2025. GOES-16 is now maintained in on-orbit storage as a backup for NOAA's operational geostationary constellation.

A geostationary satellite circles Earth above the equator in the same direction and with the same period as Earth's rotation, making it appear nearly fixed over one longitude. This requires an altitude of about 35,786 km (22,236 mi) above the equator and an orbital period close to one sidereal day. GOES-16's Advanced Baseline Imager observes Earth in 16 spectral bands. Visible and infrared measurements let forecasters compare cloud structure, temperature, moisture and rapidly changing weather during both day and night. The Geostationary Lightning Mapper detects lightning activity over large regions. Rapid increases in lightning can help forecasters recognize intensifying thunderstorms before some hazards reach the ground.

The GOES-R spacecraft lifted off on 19 November 2016 at 6:42 p.m. EST aboard a United Launch Alliance Atlas V 541 from Cape Canaveral Air Force Station in Florida. After reaching its designated orbit and beginning checkout, GOES-R was renamed GOES-16. NOAA and NASA then calibrated and validated its six instruments before operational service began.
