摘要

The GMES Sentinel-2 system will provide data continuity of SPOT and Landsat multi-spectral sensors. Both Sentinel-rn2 A and Sentinel-2B satellites currently under development will ensure systematic global acquisition of all land andrncoastal waters in the visible and short-wave infrared spectral domain with a 5 day revisit time at the equator.rnThe Multi Spectral Instrument is a push-broom imager providing imagery in 13 spectral channels with spatial resolutionsrnranging from 10 m to 60 m and a swath width of 290 Km, larger than SPOT and Landsat. The instrument features a fullrnfield of view calibration device, a silicon carbide Three Mirror Anastigmat telescope with mirror dimensions up to 600rnmm, specific filter stripe assemblies, newly developed Si-CMOS and HgCDTe detectors and a low noise waveletrncompression video electronics. The 1.4 Tbits/s raw image date rate is reduced down to 490 Mbits/s at the output of therninstrument to cope with the overall system transmission capability.rnThe Sentinel-2 program has entered in the CD phase in 2009. Launch of Sentinel-2A satellite is scheduled for 2013.
