Like the previous generation of Meteosat satellites, MSG is spin-stabilised. When operating in geostationary orbit, the satellite spins counter-clockwise at 100 rpm around its longitudinal axis, which is aligned with the Earth's rotational axis. The MSG satellites are placed in orbit at 0 degrees longitude, like the first generation Meteosats, but can be moved up to 50 degrees east or west if required.

The MSG body is a cylindrical-shaped solar drum, 3.2 m in diameter and 2.4 m high. The satellite itself is built in a modular way around three main sub-assemblies:

The Spinning Enhanced Visible and Infrared Imager (SEVIRI) instrument in the central compartment

The Mission Communication Payload (MCP), including antennas and transponders, in the upper compartment

The platform support sub-systems, in the lower compartment.

For its initial boost into geostationary orbit as well as for station keeping, the satellite uses a bi-propellant system. This includes small thrusters, which are also used for attitude control. The MSG solar array, built from eight curved panels is wrapped around the satellite body.

The MSG spacecraft have been designed for launch by Europe's Ariane-4 or Ariane-5 launchers from Kourou, in French Guiana. Each satellite has a planned operating lifetime of seven years.
