The Sentinel Collaborative Ground Segment initiative was introduced in 2011 by ESA and its Member States, to foster the Sentinel data exploitation in Europe .

Further to the announcement of 27 December 2016, Sentinel-2A MSI decontamination is now planned to take place between 09 January 2017, 07:30 UTC and 10 January 2017, 06:30 UTC.

Due to a planned MSI (MultiSpectral Instrument) decontamination, Sentinel-2A data will be unavailable for approximately 24 hours between 6 and 7 January 2017.

Further to the news of 20 December related to a Sentinel-3A OLCI anomaly, users are informed that nominal acquisitions resumed on 20 December 2016, 11:48 UTC.

Sentinel App season update

20 December 2016

A new update of the ESA Sentinel App is coming soon. The latest changes have brought us the acquisition plans and swath animations for Sentinel-1A, Sentinel-1B and Sentinel-2A, a powerful visualisation of Sentinel product availability on the geographic and temporal dimensions, the highlights of the Sentinel-1 mission achievements and even a more complete picture of the satellite surroundings in the 3D model section, with the Earth, the Moon, the Sun and the stars now visible.

Sentinel-3A OLCI anomaly

20 December 2016

Due to an instrument anomaly, the quality of Sentinel-3A OLCI L1 products has been degraded since 18 December 2016, 17:43.

A new version of the Sentinel-3 Altimetry Technical Guide is now available and provides an in-depth description of the products, algorithms and instrument performance for the mission's Altimetry component.

The Sentinel-2 satellite of the Copernicus Programme is proving to benefit land and urban monitoring, with its high resolution and repetitive coverage.

ESA is pleased to announce the first official release of Sentinel-3A OLCI Level 1 Non Time Critical (NTC) data products in the Sentinel Data Hub. Please note that the Sentinel-3A OLCI Level 1 Near Real Time (NRT) data were already released on 20 October 2016.

ESA is pleased to announce the first official release of Sentinel-3A SRAL Level 1B and Level 2 Land data products in the Sentinel Data Hub.
