SSTL to handle Galileo satellites

Surrey Satellite Technology (SSTL) has been selected by ESA to supply 14 navigation payloads for the deployment phase of the Galileo satellite navigation system. SSTL is teamed with OHB–System of Bremen, Germany for the provision of these fully operational Galileo satellites. The two companies agreed to work together as a “core team” on Galileo, with OHB taking the role of prime contractor and builder of the spacecraft “bus” and SSTL taking full responsibility for the navigation payloads onboard the satellite that will form the heart of the Galileo navigation system. Each satellite will carry two different types of highly accurate atomic clocks which are used to generate navigation messages that are broadcast by the satellites directly to the users’ Galileo receivers. Under the contract, SSTL will be responsible for the design, manufacture and test of these navigation payloads using equipment procured mainly from European suppliers. SSTL will also manufacture some of the electronics to interface the satellite bus built by OHB-System and the navigation payload.

SES ASTRA awarded second Navigation Payload for EGNOS

SES ASTRA has been awarded a second contract by the European Commission (EC) to provide hosted payload services for EGNOS. The contract was awarded following a tender by the European Commission. The new payload will operate in L-band and be located onboard SES ASTRA’s new ASTRA 5B satellite that was recently ordered from EADS ASTRIUM. The satellite is scheduled for launch in the second quarter of 2013 and will be positioned at SES ASTRA’s 31.5 degrees East orbital position. In addition to the payload, SES ASTRA will also provide the related ground infrastructure needed to operate the awarded payload.

Major Galileo contracts signed

Mr René Oosterlinck, ESA’s Director of the Galileo Programme and Navigation-related Activities, signed the first three contracts for the Galileo full operational capability phase. This event marks the start of building the Galileo operational infrastructure. The signing ceremony took place at ESA’s European Space Research and Technology Centre at Noordwijk (The Netherlands) in the presence of Mr Matthias Ruete, Director General ‘Energy and Transport’ of the European Commission (EC) and Mr Jean-Jacques Dordain, ESA’s Director General. These contracts cover system, satellites and launch activities.
The contract signed with Thales Alenia Space (Italy) covers the industrial system support activities provided to ESA as Galileo system prime: system engineering, system performance, system assembly, integration and validation, signal-in-space engineering, security engineering and product assurance. For the space segment, and following the signature of framework contracts with OHB-System AG (Germany) and EADS at the end of 2009, the first work order signed with OHB covers the manufacture of 14 satellites, with delivery of the first satellite in July 2012, followed by two satellites every three months.
As prime contractor, OHB teamed up with Surrey Satellite Technology Limited (SSTL; UK). OHB will lead the system level activities and is responsible for the spacecraft platform. SSTL is responsible for the satellite payload. For launch services, the contract covers the provision by Arianespace of five Soyuz launchers with an upgraded Fregat upper stage, to be launched from Europe’s Spaceport in French Guiana, each placing two satellites in their final orbit.
