Paper Abstract

Launched on March 6th, 2017 from Kourou, Sentinel 2B has passed the phase of commissioning. Sentinel 2B will work together with Sentinel 2A launched in June 2015. The building and implementation of the satellite has been made under the responsibility of ESA, for the European Commission. The subset of Image Quality commissioning was delegated by ESA to CNES, referring to the experience of the French Space Agency on previous imagers. This phase lasted 4 months after the launch, a little longer than the formal In Orbit Calibration period conducted by ESA, some Image Quality parameters requiring several months before converging to a stable state. This paper presents the status of the satellite, from an IQ prospective, just before it entered its operational phase. The radiometric and geometric performances are listed, including: the absolute radiometric calibration, the equalization, the SNR, the absolute and the multi-temporal location accuracy. The performances of both satellites Sentinel and Sentinel 2B working together, will be addressed. A particular focus will be done on multi-temporal location performances, homogeneity of radiometric inter calibrations. The accomplishment of the Global Reference Image over Europe is evoked as well. The IQ commissioning phase ended on June 2017. From this date, the monitoring of IQ parameters is under the responsibility of ESA/ESRIN. Nevertheless, CNES continues to support ESA to survey the accuracy of S2A and S2B performances. The article ends by dealing with the prospective offered by the couple Sentinel 2A + Sentinel 2B.
