N° 32–2013: ESA drives forward with all-electric telecom satellites

16 October 2013

ESA is set to begin developing a new generation of satellites propelled by solar electric thrusters, following the signing of a contract with SES of Luxembourg for the next phase of the Electra project.

Electra is a partnership between ESA and satellite operator SES to define, develop and validate in space an electric-only propulsion platform for geostationary telecommunication satellites of around 3 tonnes launch mass.

The first launch is expected by the end of 2018.

Electra is the first partnership project established under ESA’s ARTES-33 programme, which supports market-driven innovations from industry that require flight heritage and in-orbit validation – proof that they work in space – so that they are more readily embraced by the marketplace.

ARTES-33 requires a partnership between a manufacturer and a user of the innovative capabilities and demands that innovation is validated in a commercially representative environment.

Through Electra, Europe’s new capability will serve the current and future needs of satellite operators in the geostationary segment for smaller satellites.

The use of electric-only propulsion for orbit raising and stationkeeping yields important savings in fuel consumption, reducing launch mass by 40%. This allows payloads to be twice as large or the use of smaller launch vehicles. Either way, it is economically attractive.

German satellite builder OHB Systems is in partnership with SES for the development of Electra. OHB aims to extend its portfolio of telecom satellite platforms, adding a fully electric version to the Small GEO product line with Electra.

The Electra project encompasses both the development of the platform and the flight of a mission defined by the satellite operator. The mission will be selected at the end of this Phase-B1 in 2014.

Jean-Jacques Dordain, ESA’s Director General, attending the signing of the contract at SES in Luxembourg, noted: “Electra represents three partnerships in one: between SES and OHB, to develop the best solution for SES and the future needs of other satellite operators; between SES and ESA, to offer the best possible validation in orbit of a new technology; and between ESA and DLR to capitalise on previous investments. These three partnerships is the best way to optimise the use of public and private funds for enhancing the competitiveness of the European sector."

Rolf Densing, Director of ESA Space Programmes at the DLR German Aerospace Center, commented: “Electra is a good example of the kind of cooperation we are seeking with ESA in the area of telecommunications. It maximises the outcome for German industry in terms of potential commercial exploitation.

“At the same time, Electra imposes a rigorous framework on all the parties involved, derived from the high commercial stakes. With Electra we continue our strategy to establish a prime for small telecommunication satellites in Germany” 

Magali Vaissiere, ESA’s Director of Telecommunication and Integrated Applications, added, “We are adapting our tools to best support the competitiveness of our satellite telecommunication industry.

“Electra is the first example of our Partner programme, where we are consolidating the model of partnerships with the private sector to help the introduction and adoption of innovative efficient solutions proposed by our industry.

“SES is not only a world-leading satellite operator but also a key reference for the consolidation of OHB as a prime contractor in the commercial satcom sector.”

About the European Space Agency

The European Space Agency (ESA) is Europe’s gateway to space. It is an intergovernmental organisation, created in 1975, with the mission to shape the development of Europe’s space capability and ensure that investment in space delivers benefits to the citizens of Europe and the world.

ESA has 20 Member States: Austria, Belgium, the Czech Republic, Denmark, Finland, France, Germany, Greece, Ireland, Italy, Luxembourg, the Netherlands, Norway, Poland, Portugal, Romania, Spain, Sweden, Switzerland and the United Kingdom, of whom 18 are Member States of the EU.

ESA has Cooperation Agreements with eight other Member States of the EU. Canada takes part in some ESA programmes under a Cooperation Agreement.

ESA is also working actively with the EU on implementing the Galileo and Copernicus programmes.

By coordinating the financial and intellectual resources of its members, ESA can undertake programmes and activities far beyond the scope of any single European country.

ESA develops the launchers, spacecraft and ground facilities needed to keep Europe at the forefront of global space activities.

Today, it launches satellites for Earth observation, navigation, telecommunications and astronomy, sends probes to the far reaches of the Solar System and cooperates in the human exploration of space.
