The 13th launch in the Galileo programme, performed by SpaceX under contract with ESA, has taken Galileo satellites number 31 and 32 (FM26 and FM32) to medium Earth orbit, extending the constellation to make it more robust. In the coming weeks, the new satellites will reach their final destination at 23 222 km, where they will be tested prior to starting operations.

ESA Director of Navigation Javier Benedicto said, “With the deployment of these two satellites, Galileo completes its constellation as designed, reaching the required operational satellites plus one spare per orbital plane. The remaining 6 Galileo First Generation satellites are expected to be deployed in 2025 and 2026 for increased robustness and performance, solidifying the resilience and reliability of Galileo and enabling uninterrupted delivery of the world’s most precise navigation.”

ESA, as design authority and system development prime, together with manufacturer OHB, has developed and tested 38 satellites since the conception of Galileo. All but six satellites have been launched, with the remaining ones ready to join the constellation starting next year. They will be launched in pairs by Ariane 6, ESA’s new launcher that successfully completed its inaugural flight in July. Thereafter, the first batch of Galileo Second Generation (G2) satellites, currently under development by Thales Alenia Space and Airbus Defence and Space, will also be placed in orbit by ESA’s heavy launcher.
