The development of meteorological satellites of EUMETSAT/ESA is summarized and its program of next generation weather satellites used both in geostationary orbit and in polar orbit is presented. The next generation of geostationary weather satellites in MTG series will include an imaging satellite (MTG-I) and a sounding satellite (MTG-S). Both satellites will operate simultaneously and each of them will load different detection instruments. Six satellites (four MTG-I satellites and two MTG-S satellites) in MTG series are planned to be launched in the future. The polar orbit weather satellite named MetOp-SG will operate cooperatively with the satellite system of NOAA/NASA. The next generation satellite MetOp-SG of ESA will provide “morning” service just as the current MetOp satellite, and the next generation of JPSS satellite of NOAA/NASA will provide “afternoon” service. The data or information from MetOp-SG and JPSS satellites will be shared by both sides.
