Sentinel-2B already in the orbit
At this point, a three-day payroll operation is being carried out and all subsystems are checked and calibrated. The Sentinel-2B will be fully operational in 3-4 months. The new satellite will be placed on the opposite side of orbit that Sentinel-2A is situated at. It will acquire data from the Earth’s surface in 290 km-wide swath. Thanks to such a system, the revisit time over the same area will shorten to 5 days.
The Sentinel-2 constellation is the first satellite mission providing high-resolution data with open license with such a short revisit time. Sentinel-2 satellite data is free and public on the Copernicus Open Access Hub.
The Sentinel-2 is a state-of-the-art multispectral scanner with a wide field of view, high spatial resolution and 13 spectral channels. Mission of Sentinel-2 allows for monitoring of the Earth, providing data on agriculture, forestry, spatial planning and crisis management. Among others it will help in the detection of floods, fires, landslides and eruption of volcanoes.
