EUMETSAT ready to take over the MSG-4 satellite

EUMETSAT is ready to take control of the MSG-4 spacecraft on 26 July and start the commissioning of the full MSG-4 system. This will ensure that all systems, in orbit and on ground, meet the requirements of the operational service MSG-4 will eventually have to deliver.

tn - MSG-4 - commissioning

The MSG-4 satellite was launched on 15 July at 23:42 CEST aboard an Ariane 5 rocket from Europe’s Spaceport in French Guiana and is en route to geostationary orbit. It is currently controlled by ESOC, which performs the Launch and Early Operations (LEOP) service under EUMETSAT contract.

EUMETSAT’s own ground systems and operations teams are ready to take over control of the satellite from ESOC after the successful completion of the LEOP, foreseen around 26 July, and to start the commissioning of the full MSG-4 system.

This will involve all EUMETSAT ground systems used to control the spacecraft, receive and process their imagery and deliver quality-controlled products to users worldwide.

The capacity of the systems has been expanded to support a fourth MSG spacecraft in orbit and, after a successful test campaign, all systems and the EUMETSAT operations teams are ready to commission and operate MSG-4, in addition to Meteosat-8, -9 and -10, which are already in orbit.  

During commissioning, EUMETSAT will conduct an extensive testing programme to verify the end-to-end system performance. This will start with testing the spacecraft in orbit with the support of ESA, to confirm its full functionality after launch, including switching on the communications and imager payloads and taking the first image. This will be followed by trial dissemination of image data to a subset of expert users and the thorough validation of image data and extracted environmental products by EUMETSAT, based on the execution of a detailed system commissioning plan.

Upon the successful conclusion of the commissioning phase, MSG-4 will be declared operational, renamed Meteosat-11, and stored in orbit, where it will remain until needed to replace one of the older Meteosat satellites.

The MSG series of geostationary satellites ensures the safety of lives, property and infrastructure through its critical value for the nowcasting of high impact weather.


The European Organisation for the Exploitation of Meteorological Satellites is an intergovernmental organisation based in Darmstadt, Germany, currently with 30 Member States (Austria, Belgium, Bulgaria, Croatia, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, the Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom) and one Cooperating State (Serbia).

EUMETSAT operates the geostationary satellites Meteosat-8, -9 and -10 over Europe and Africa, and Meteosat-7 over the Indian Ocean.

EUMETSAT also operates two Metop polar-orbiting satellites as part of the Initial Joint Polar System (IJPS) shared with the US National Oceanic and Atmospheric Administration (NOAA).

EUMETSAT is also a partner in the Jason ocean altimetry missions exploited jointly with NOAA, NASA and CNES.

The data and products from EUMETSAT’s satellites are vital to weather forecasting and make a significant contribution to the monitoring of environment and the global climate.

From 2016 onwards, EUMETSAT will exploit the Copernicus Sentinel-3 marine mission, in cooperation with ESA and on behalf of the EU, and deliver data services to the Copernicus Marine Environment Monitoring Service.
