SENTINEL 1B Telescope Orbit Orbit

Sentinel-1B, the second spacecraft in the Sentinel-1 family of synthetic aperture radar (SAR) observation satellites, is part of a vast joint research program by ESA and the European Union called Copernicus. Copernicus aims to provide operational information on land masses, oceans and the Earth’s atmosphere – data that will play a critical role in determining the policies needed to protect our environment and security, and to meet the needs of both consumers and service providers.
