Eight more Galileo satellites

OHB-System AG and Surrey Satellite Technology Ltd (SSTL) have been contracted to build a further 8 Galileo satellites.

German satellite manufacturer OHB-System AG has authorised Surrey Satellite Technology Ltd (SSTL) to start work on building a further 8 navigation payloads for Galileo. The total contract with the 2 companies is worth ~ €140 (£123, $157) million, and it is a continuation of successful cooperation between the companies, which have previously built all 22 Full Operational Capability (FOC) satellites for the constellation. Fourteen FOC navigation payloads are currently operational in orbit, with a further 8 already delivered to OHB for integration and test.

SSTL’s Director of Navigation comments: 'SSTL is delighted to have been selected to build the third batch of navigation payloads needed to complete the initial Galileo constellation. I am confident that the OHB-SSTL solution offered the lowest risk and best value for money, and I believe that our selection as payload providers for the third time in succession demonstrates a high regard for our work.'

SSTL’s Galileo FOC payload includes European-sourced atomic clocks, navigation signal generators, high power travelling wave tube amplifiers and antennas. The proposal for Batch 3 is for a recurrent build of the existing payload, but with an evolution of the atomic clocks to incorporate advances made under the European GNSS Evolution Programme.

SSTL designed and built GIOVE-A, Galileo’s pathfinder mission, launched in 2005 and still operational today. An order for 14 satellites was placed with OHB-SSTL team in 2010, with a further 8 ordered in 2012. FOC satellite launches began in 2011, with system completion scheduled for 2020.

The FOC programme is managed and fully funded by the EU, with ESA acting as design and procurement agent on behalf of the Commission.
