Galileo Second-generation Satellites Ready to Navigate into the Future

Galileo Second-generation Satellites Ready to Navigate into the Future

Airbus has successfully completed the Preliminary Design Review (PDR) for its system concept for the second-generation Galileo navigation satellites. During this important milestone, Airbus' proposed preliminary design and the customer's system requirements have been fully reviewed and agreed.

This paves the way for further verification, acceptance and qualification at equipment and module level. Verification at payload level is already in full swing, with the Critical Design Review (CDR) for the satellite structure also due shortly.

Rapidly Emerging and Changing User Needs

In parallel, the Airbus site in Friedrichshafen, on Lake Constance, Germany, is preparing for an industrialized production line for currently six second-generation Galileo satellites. The satellite integration centre is being completely upgraded to meet current and future requirements for efficient, environmentally friendly, safe and secure production for the Galileo second-generation satellites. This is a key milestone in European satellite navigation services that European citizens and billions of users around the world will benefit from, powered by Airbus know-how brought to the project by over 200 highly skilled space engineers. The first Galileo second-generation satellites are planned to be launched in 2024.

The world of navigation is changing, driven by rapidly emerging and changing user needs (availability and reliability), a growing number of security threats (jamming and spoofing) and the evolution of other navigation systems. The new batch of Galileo spacecraft built by Airbus is the answer to this changing context. It will make the Galileo service more accurate, secure, dependable and adaptable over its lifetime spanning two decades.

Combining Heritage and In-orbit Experience

Weighing around 2.3 tons, each satellite is designed to operate for about 15 years. The state-of-the-art and all-electric medium-Earth orbit (MEO) platform from Airbus reuses flight-proven building blocks from the company's Telecoms and Earth Observation programmes, taking advantage of a combination of heritage and in-orbit experience. The flexible and modular navigation payload solution with future growth capability is also based on telecom elements for beam forming and signal generation.

Galileo is managed and funded by the European Union. The European Commission, ESA and EUSPA have signed an agreement by which ESA acts as design authority and system development prime on behalf of the Commission and EUSPA as the exploitation and operation manager of Galileo. The views expressed here can in no way be taken to reflect the opinion of the European Union and/or ESA.
