ESA - Sentinel-2 updates
« on: 04/17/2008 10:42 AM »


The European Space Agency and Astrium today signed a ?195 million contract to provide the first Sentinel-2 earth observation satellite, devoted to monitoring the land environment, as part of the European GMES programme. As prime contractor, Astrium is responsible for the design, development and integration of the satellite, which will perform a high-end multi-spectral optical imaging mission.

The contract was signed today in Friedrichshafen by Volker Liebig, ESA Director of Earth Observation, Evert Dudok, President of Astrium Satellites, and Uwe Minne, Director of Earth Observation & Science for Astrium, in the presence of the European Commission and Ulrich Kasparick, German Parliamentary State Secretary at the Transport, Building & Urban Affairs Ministry.

Underlining the value of this mission for Europe, Volker Liebig commented: "This satellite is an important element of GMES and will enable Europe to continuously observe changes in the environment".

Global Monitoring for Environment and Security (GMES) aims to deliver environment and security services and is being led by the European Commission. It is the European response to the ever-increasing demands of effective environmental policies. At the same time, it is the European contribution to the Global Earth Observation System of Systems (GEOSS). ESA is responsible for implementation of the GMES Space Component, a set of earth observation missions involving ESA, EU/ESA Member States and other partners. Central elements of the Space Component are the five families of Sentinel missions.

Sentinel-2 will deliver crucial data for information services to the EU and its Member States under GMES. The services fed by it cover areas such as climate change, sustainable development, environmental policies, European civil protection, common agricultural policy, development aid, humanitarian aid and the Common Foreign & Security Policy. Sentinel-2 will 
support the operational generation of products such as the mapping of land cover, land use, change detection and geophysical variables. The mission objective is systematic coverage of the earth's land surface (from -56° to +83° latitude) to produce cloud-free imagery typically every 15 to 30 days over Europe.

Sentinel-2 features a 290 km-wide coverage, 10-20 m spatial resolution, 13 optical channel instrument (operating from visible-near infrared to shortwave infrared) and will ensure enhanced-quality continuity with existing missions Spot and Landsat. It will provide improved revisit time, swath width, coverage area, spectral bands, calibration and image quality. These features will enable it to contribute effectively to GMES needs for operational land and emergency services.

ESA carried out the Sentinel-2 definition phase over 2005/2006. The implementation phase started in October 2007. The launch of the first Sentinel-2 satellite is planned for 2012. The industrial consortium led by Astrium-GmbH (platform and satellite prime) includes a number of core-team partners: Astrium SAS is responsible for the payload instrument and system support activities; Boostec (F) is providing the three-mirror Silicon carbide telescope; CASA (E) is responsible for satellite structural and thermal activities; Jena-Optronik (D) is responsible for the instrument electrical architecture including video signal processing and data compression; Sener (E) is supplying the instrument calibration and shutter mechanism.

Sentinel 2

The pair of Sentinel-2 satellites will routinely deliver high-resolution optical images globally, providing enhanced continuity of SPOT- and Landsat-type data.

Sentinel-2 will carry an optical payload with visible, near infrared and shortwave infrared sensors comprising 13 spectral bands: 4 bands at 10 m, 6 bands at 20 m and 3 bands at 60 m spatial resolution (the latter is dedicated to atmospheric corrections and cloud screening), with a swath width of 290 km.

The 13 spectral bands guarantee consistent time series, showing variability in land surface conditions and minimising any artefacts introduced by atmospheric variability.

The mission orbits at a mean altitude of approximately 800 km and, with the pair of satellites in operation, has a revisit time of five days at the equator (under cloud-free conditions) and 2–3 days at mid-latitudes.

SENTINEL-2

Sentinel-2A completed its functional test campaign at Airbus Defence & Space (DE) and was shipped to IABG in August to undergo its environmental test campaign.

The Optical Communication Payload (that will be used to recover mission data through EDRS) will be delivered, integrated and tested in December prior to the final EMC radiated qualification test campaign. By the end of the EMC tests in February 2015, and pending confirmation from the Sentinel-2A Qualification and Acceptance Review Board scheduled in March 2015, Sentinel-2A will be ready for shipment to Europe’s Spaceport. On this basis, the Sentinel-2A launch is planned for early 2015.

In-orbit commissioning preparations are conducted concurrently with the involvement of all the teams involved for operating, calibrating, validating and exploiting the Sentinel-2 mission. In the meantime, the functional testing of the second FM satellite is ongoing at Airbus Defence & Space (DE) and the delivery of the second payload instrument FM by Airbus Defence & Space (FR) is expected in July 2015. The good development status is consistent with a Sentinel-2B launch readiness in Spring 2016.

Stretching wide

The final solar wing deployment test marks the end of a six-month programme at IABG in Germany to make sure the satellite can withstand the shocks and vibrations during liftoff and that it is fit for a long working life in the harsh environment of space. The next step is to pack up the satellite in its container and ship it to Europe's Spaceport in French Guiana for launch, which is scheduled for 12 June 2015.

Offering ‘colour vision’ for the European Commission’s environmental monitoring Copernicus programme, Sentinel-2A combines high-resolution and novel multispectral capabilities – a first for ESA.

Sentinel-2B:

ESA released a timelapse video of the satellite- and launchpreparation up to and including the lift-off.



Quote
This timelapse video shows Sentinel-2B satellite, from final preparations to liftoff on a Vega launcher, flight VV09, from Europe’s Spaceport in French Guiana, on 7 March 2017.

Sentinel-2B is the second satellite in the Sentinel-2 mission for Europe’s Copernicus environment monitoring programme.

Designed as a two-satellite constellation – Sentinel-2A and -2B – the Sentinel-2 mission carries an innovative wide swath high-resolution multispectral imager with 13 spectral bands for a new perspective of our land and vegetation. This information is used for agricultural and forestry practices and for helping manage food security. It also provides information on pollution in lakes and coastal waters. Images of floods, volcanic eruptions and landslides contribute to disaster mapping and help humanitarian relief efforts.

First Sentinel-2B images delivered by laser

http://www.esa.int/Our_Activities/Observing_the_Earth/Copernicus/Sentinel-2/First_Sentinel-2B_images_delivered_by_laser

Quote
With the Sentinel-2B satellite close to beginning its working life in orbit, this latest Copernicus satellite has linked up to Alphasat by laser, across almost 36 000 km of space, to deliver images of Earth just moments after they were captured.

The test, which was done as part of Sentinel-2B’s commissioning, included capturing a strip of images from Europe to North Africa and downlinking the data in just six minutes.
