TL;DR: An overview of the GMES Sentinel-2 mission including a technical system concept overview, image quality, Level 1 data processing and operational applications is provided.

TL;DR: The Centre National d'Etudes Spatiales (CNES) supports ESA to define the system image products and to prototype the relevant image processing techniques.

TL;DR: In this paper, an overview of the Sentinel-2 optical imaging system is presented, which is based on a satellites constellation deployed in polar sun-synchronous orbit and includes radiometric corrections (dark signal, pixels response non uniformity, crosstalk, defective pixels, restoration, and binning for 60 m bands); and an enhanced physical geometric model appended to the product but not applied, the Level-1C product is tiled following a pre-defined grid of 100x100 km2, based on UTM/WGS84 reference frame.

TL;DR: The different geometric (line of sight, focal plane cartography, ...) and radiometric (relative and absolute camera sensitivity) in-flight calibration methods that will take advantage of the on-board sun diffuser and ground targets to answer the severe mission requirements are discussed.

TL;DR: The Sentinel-2 mission as mentioned in this paper is based on a twin satellites configuration deployed in polar sun-synchronous orbit and designed to offer a unique combination of systematic global coverage, high revisit (five days at equator with two satellites) and high spatial resolution imagery.
