The European Galileo satellite-based navigation system now has 30 satellites in orbit, following the launch of the latest two aboard a SpaceX Falcon 9 rocket on 28 April.
The new satellites are currently under the control of European Union Agency for the Space Programme (EUSPA) teams at the Galileo Control Centre in Oberpfaffenhofen, Germany, as well as the Galileo Service Operator, a consortium led by SpaceOpal.
The EUSPA and SpaceOpal teams are responsible for commissioning subsystems and manoeuvring the satellites until the start of the drift phase, which should take around four weeks and will be complete when the Drift Stop and Fine Positioning (DSFP) manoeuvres are undertaken for each satellite as they reach their final orbital location.
Once that is done, an In-Orbit Test campaign will assess the performance of the satellites’ navigation payloads.
“Galileo underscores the power of collaboration. With the European Commission, EUSPA and ESA working hand in hand. Galileo isn’t just about satellites; it’s a testament to our shared commitment to innovation, security, and progress. Together, we’re empowering billions worldwide, enabling precise navigation and enhancing transportation,” said R. da Costa, EUSPA Executive Director.
The latest launch took place only a few days after broadcast began of Galileo’s new Public Regulated Service (PRS) signals. PRS is an encrypted service intended for authorised governmental users and sensitive applications.
Eight more Galileo First Generation satellites are scheduled for launch soon, following which the first of the Second Generation (G2) satellites will begin joining the constellation. The first G2 launch is expected to take place in 2026 aboard an Ariane 6 launcher.
The G2 satellites will use electric propulsion and feature a more powerful navigation antenna, more and even better atomic clocks and fully digital payloads.
