This fourteenth launch further strengthens the resilience of Europe’s satellite navigation network, enhancing the system’s ability to guarantee precision, availability, and service continuity. The addition of the two new satellites reinforces the Galileo constellation, making the signal more stable and reliable worldwide for all applications and users that rely on extremely accurate timing and positioning, including transport, telecommunications, emergency services, digital infrastructures, and intelligent mobility systems.
Immediately after launch, the most critical mission activities — the Launch and Early Orbit Phase (LEOP) — were entrusted to Spaceopal, the joint venture equally owned by Telespazio and DLR/GfR and responsible for the operational management and maintenance of the Galileo system. During this crucial phase, which marks the beginning of the satellites’ operational life, Spaceopal handled the acquisition of the first signals and initiated the checks and manoeuvres required to correctly position the satellites in orbit.
As the Galileo Service Operator, Spaceopal is responsible for system operations, managing both the space and ground segments of the programme. Its activities include constellation and mission control through the coordinated use of the ground segments hosted at the two Galileo Control Centres in Fucino (Italy) and Oberpfaffenhofen (Germany), as well as at remote sites distributed around the globe. SpaceOpal also oversees the implementation and management of the Galileo data transmission network, security supervision, logistics, maintenance, and performance monitoring of the entire system.
The operational activities carried out by Spaceopal ensure the provision of navigation services and the dissemination of data to users, with the objective of maintaining the high quality and reliability of Galileo’s global performance.
A decisive contribution to Spaceopal’s success and to the overall quality of the services delivered comes from the infrastructures and expertise of Telespazio, a Leonardo Group company. Telespazio is engaged at the Italian Galileo Control Centre in monitoring and continuously updating the navigation message and coordinating ground assets. The Fucino Space Centre is one of the operational pillars of the Galileo programme and guarantees service continuity during key mission phases.
Leonardo also plays a strategic role by providing some of the most sensitive technologies aboard the Galileo satellites. In addition to Telespazio’s contribution to Galileo services, Leonardo supplies key technologies for the programme. Each satellite carries two atomic clocks (Passive Hydrogen Masers – PHMs), developed by Leonardo at its Nerviano (Milan) site, which form the core of Galileo’s exceptional precision. These are the most accurate atomic clocks ever developed for satellite navigation applications: their stability allows an error of just one second over millions of years, a level of performance that is essential to ensure the high positioning accuracy and time synchronisation delivered by Europe’s navigation system. Leonardo is also developing a new atomic clock technology for future satellites in the programme.
All satellites in the constellation are also equipped with attitude sensors developed by Leonardo at its Campi Bisenzio (Florence) facility, which are essential for precise control of the satellite’s orientation in space.
Furthermore, for Galileo’s Public Regulated Service (PRS) — the encrypted navigation service for authorised users and sensitive applications — Leonardo designed and developed in Genoa the user terminals and the software, comprising millions of lines of code, for the service’s security centres (Galileo Security Monitoring Centre).
With this launch, the First Generation fleet is now approaching completion. Four additional satellites are still planned, which will finalise the current configuration and pave the way for the transition to Galileo Second Generation. This new phase of the programme will introduce even more advanced capabilities and performance, designed to meet the needs of the coming decade and to consolidate Europe’s strategic role in the satellite navigation sector.
