First Galileo satellites accepted

The first two Galileo satellites have successfully passed ESA’s technical acceptance review prior to their launch in October.

The European Space Agency (ESA) has accepted the first and second Galileo In-Orbit Validation (IOV) satellites as part of their quality acceptance review - a major milestone in the programme.

The satellites were designed and manufactured by a team under the leadership of Astrium Germany, with Institute Corporate Member Astrium UK overseeing the development and integration of the navigation payload.

The first of 4 IOV satellites - which will form part of the final full 30-satellite constellation - has already arrived at the European Space Centre in Kourou (see previous news below).

These first 2 Flight Model satellites (FM1 and FM2) are due to be launched aboard a Soyuz ST-B vehicle on 20 October - the first Soyuz launch from French Guiana.

The satellites will be joined in orbit in 2012 by the other two Astrium IOV satellites. These four satellites will validate the Galileo system design - four being the minimum required to provide 3-D positioning.

Details from Astrium below.
