Description:

• An Arianespace Soyuz rocket will launch on a mission from the Guiana Space Center in South America. The Soyuz will carry two Galileo full operational capability satellites for Europe's Galileo navigation constellation. The Soyuz 2-1b rocket will use a Fregat-MT upper stage. Arianespace will oversee the launch.
• The FOC satellites have a mass of 733 kg full 660 kg dry and are built by OHB (Bremen) with navigation payloads by SSTL (Guildford) and a propulsion system from Moog ISP (Niagara Falls) with eight 1N MONARC-1 hydrazine thrusters. (Moog ISP is the former Bell Aerospace, which built the Agena engine). The earlier IOV test satellites were partly owned by ESA, but the FOC satellites are owned by the European Union's GSA (Global Navigation Satellite Systems Agency), based in Prague. The FOC satellites carry two rubidium and two hydrogen maser atomic clocks and broadcast on L-band; they also carry the MEOSAR search and rescue transponder payload.

Mission details:

• Launch delayed from .
• The European Commission's GalileoSat-7 and 8 (ESA designation Galileo FOC FM03 and FM04) were launched on Mar 27, 2015 by a Soyuz/Fregat. This time the launch went perfectly and delivered the satellites to a 23500 x 23580 km x 55.1 deg orbit.
