List of Galileo satellites
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.[1]
As of September 2024, 32 Galileo (4 In Orbit Validation (IOV) and 28 Full Operational Capability (FOC) satellites have been launched). The 2 Galileo In-Orbit Validation Element (GIOVE) prototype vehicles were retired in 2012. Currently, 27 satellites are operational, 4 are not usable and 1 is decommissioned.
The remaining 6 FOC satellites have completed manufacturing and testing. They are currently in storage awaiting launch by Ariane 6.[2]
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.[3][4]
- Batch 1 consists of 14 FOC satellites (Galileo-FOC FM1 to Galileo-FOC FM14)
- Batch 2 consists of 8 FOC satellites (Galileo-FOC FM15 to Galileo-FOC FM22)
- Batch 3 consists of 12 FOC satellites (Galileo-FOC FM23 to Galileo-FOC FM34)
In parallel to Batch 3's completion, the 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.[3][5][6][7][8]

Satellites
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.[9]
