The Sentinel-1B satellite is moved to the fuelling and integration facility at Europe's Spaceport in Kourou, French Guiana, where it is being prepared for launch on 22 April 2016.
Sentinel-1B will join its identical sister satellite, Sentinel-1A, in orbit to provide 'radar vision' for Europe's environmental Copernicus programme. Sentinel-1A was launched on 3 April 2014. As a constellation of two satellites orbiting Earth 180 degrees apart, revisit times and global coverage are optimised.
