This is a list of past and present satellites of the Galileo navigation system. The fully operational constellation will nominally consist of 30 satellites in Medium Earth Orbit, with 24 active and 6 spares equally divided into 3 orbital planes in a Walker 24/3/1 configuration.
As of 1 February 2026, 34 Galileo satellites have been launched, consisting of 4 In Orbit Validation (IOV) and 30 Full Operational Capability (FOC) satellites. Two separate Galileo In-Orbit Validation Element (GIOVE) prototype vehicles were retired in 2012. Currently, 26 satellites are operational, 2 are undergoing commissioning, 4 are not usable, and 2 are decommissioned.
The remaining 4 FOC satellites have completed manufacturing and testing. They are currently in storage awaiting launch by Ariane 6.
FOC satellites were awarded and built in three batches by OHB in Bremen, Germany, with the contribution of Surrey Satellite Technology (SSTL) in Guildford, United Kingdom.
In parallel to Batch 3's completion, 12 Galileo Second Generation (G2G) satellites, featuring electric propulsion, enhanced navigation signals and capabilities, inter-satellite links and reconfigurability in space, were in development by Thales Alenia Space (TAS) and Airbus Defence and Space, with their deployment expected to begin in 2027.
The initial 28 satellites were each named after a child that won the European Commission's Galileo drawing competition. One winner was selected from each member state of the European Union.
