September 14, 2017 - Arianespace will launch four new
satellites for the Galileo constellation, using two Ariane 62 versions of the
next-generation Ariane 6 rocket from the Guiana Space Center in French Guiana.
The contract will be conducted by the European Space Agency (ESA) on behalf of
the European Commission (DG Growth) and the European Union. These launches are
planned between the end of 2020 and mid-2021, using two Ariane 62 launchers ?
the configuration of Europe’s new-generation launch vehicle that is best suited
for the targeted orbit. The contract also provides for the possibility of using
the Soyuz launch vehicle from the Guiana Space Center, if needed. Both missions
will carry a pair of Galileo spacecraft to continue the constellation
deployment for Europe’s satellite-based navigation system. The satellites, each
weighing approximately 750 kg., will be placed in medium earth orbit (MEO) at
an altitude of 23,222 kilometers and be part of the Galileo satellite
