Telespazio participates in Copernicus Programme in the creation, maintenance and evolution of the Payload Data Ground Segment (PDGS) for Sentinel-1 and Sentinel-3 (led by Telespazio Germany), the Mission Control System of Sentinel-1, Sentinel-2, Sentinel-3 and Sentinel-5P and the infrastructure for access to the Earth observation products of the Copernicus missions (Copernicus Space Component Data Access/Coordinated Data Access System - CSCDA/CDS).
In the field of operations, Telespazio's staff supports ESOC (ESA's Space Operations Centre) during the pre and post launch phases of the Sentinel satellites, and is responsible for the CSCDA/CDS operations as well as the Sentinel-1 and Sentinel-2 data acquisition from the Matera Space Centre (through its subsidiary e-GEOS).
Telespazio will also be responsible for managing operations in the Sentinel-3 ground segment until 2021.
The Sentinels already provide high resolution radar and optical images of our planet and will continue to do so in the future. In particular:
Sentinel-1 is a polar-orbiting, all-weather, day-and-night radar imaging mission for land and ocean services. Sentinel-1A was launched on 3 April 2014 and Sentinel-1B on 25 April 2016.
Sentinel-2 is a polar-orbiting, multispectral high-resolution imaging mission for land monitoring to provide, for example, imagery of vegetation, soil and water cover, inland waterways and coastal areas. Sentinel-2 can also deliver information for emergency services. Sentinel-2A was launched on 23 June 2015 and Sentinel-2B on 7 March 2017.
Sentinel-3 is a multi-instrument mission to measure sea-surface topography, sea- and land-surface temperature, ocean colour and land colour with high-end accuracy and reliability. The mission supports ocean forecasting systems, as well as environmental and climate monitoring. Sentinel-3A was launched on 16 February 2016 and Sentinel-3B on 25 April 2018.
Sentinel-4 is a payload devoted to atmospheric monitoring that will be embarked upon a Meteosat Third Generation-Sounder (MTG-S) satellite in geostationary orbit.
Sentinel-5 is a payload that will monitor the atmosphere from polar orbit aboard a MetOp Second Generation satellite.
Sentinel-5 Precursor satellite mission is dedicated to atmospheric monitoring. The satellite was launched on 13 October 2017.
Sentinel-6 mission carries a radar altimeter to measure global sea-surface height, primarily for operational oceanography and for climate studies. The satellite was launched on 21 November 2020.
