Satellite propulsion:
  • The MSG propulsion system inherits the unified bi-propellant system already proven on communication satellites and some scientific missions. It includes:
    • 4 propellant tanks providing a large storage capacity (up to 965 kg of propellant)
    • 2 helium pressurant tanks
    • 2 liquid fuelled apogee motors each giving 400 N thrust for apogee manoeuvres in transfer/drift orbits
    • 6 reaction-control thrusters for fine orbital manoeuvres, attitude acquisition and maintenance

The MSG solar array is built from eight curved panels (2.4 m high and 1.25 m wide) linked in a drum skirt around the satellite body. One of the panels has a cut-out for the instrument aperture. The array is dimensioned to deliver about 720 W of power at equinox after seven years in orbit. Two Nickel-Cadmium batteries are available for eclipse periods.
