MSG-3, Europe’s latest weather satellite, delivers first image
Today, the Spinning Enhanced Visible and Infrared Imager (SEVIRI) instrument on MSG-3 captured its first image of the Earth.
This demonstrates that Europe’s latest geostationary weather satellite, launched on 5 July, is performing well and is on its way to taking over operational service after six months of commissioning.
The European Space Agency (ESA) was responsible for the initial operations after launch (the so-called launch and early orbit phase) of MSG-3 and handed over the satellite to EUMETSAT on 16 July.
MSG is a joint programme undertaken by ESA and EUMETSAT. ESA is responsible for the development of satellites fulfilling user and system requirements defined by EUMETSAT and of the procurement of recurrent satellites on its behalf. ESA also performs the Launch and Early Orbit Phase operations required to place the spacecraft in geostationary orbit, before handing it over to EUMETSAT for exploitation.
EUMETSAT develops all ground systems required to deliver products and services to users and to respond to their evolving needs, procures launch services and operates the full system for the benefit of users.
MSG-3 is the third in a series of four satellites introduced in 2002. These spin-stabilised satellites carry the primary Spinning Enhanced Visible and Infrared Imager, or SEVIRI. The prime contractor for the MSG satellites is Thales Alenia Space, with the SEVIRI instrument built by Astrium.
SEVIRI delivers enhanced weather coverage over Europe and Africa in order to improve very short range forecasts, in particular for rapidly developing thunder storms or fog. It scans Earth’s surface and atmosphere every 15 minutes in 12 different wavelengths, to track cloud development. SEVIRI can pick out features as small as a kilometre across in the visible bands, and three kilometres in the infrared.
The MSG satellites were built in Cannes, France, by a European industrial team led by Thales Alenia Space, France. More than 50 subcontractors from 13 European countries are involved.
