description Sentinel-1B Overview
Sentinel-1B was a European Space Agency (ESA) Earth observation satellite launched in April 2016 as part of the Copernicus Programme. Operating in a polar orbit, it was equipped with a C-band synthetic aperture radar (SAR) to provide continuous, all-weather day-and-night imagery of the Earth's surface. The mission supported various applications, including Arctic sea-ice monitoring, maritime surveillance, and disaster response. The satellite suffered a critical power anomaly in late 2021, permanently ending the mission before its planned decommissioning date.

Sentinel-1B launched on 25 April 2016 from Kourou in French Guiana. It was part of the European Union's Copernicus Earth-observation program.
What orbit did Sentinel-1B use?
Sentinel-1B operated in a polar low Earth orbit. It worked with Sentinel-1A as a pair to improve the frequency of coverage over many parts of Earth.
Why did Sentinel-1B stop operating?
The mission ended after a major spacecraft anomaly caused the satellite to lose operational capability. ESA announced the end of the Sentinel-1B mission in 2022, leaving Sentinel-1A to continue the original mission alone.
