This compilation enumerates both historical and current satellites belonging to the Galileo navigation system. The complete operational network is designed to consist of 30 satellites positioned in Medium Earth Orbit, with 24 actively functioning and 6 held as reserves, arranged within three orbital planes following a Walker 24/3/1 pattern.
By September 2024, a total of 32 Galileo satellites had been deployed: comprising 4 In Orbit Validation (IOV) units and 28 Full Operational Capability (FOC) satellites. The two prototype Galileo In-Orbit Validation Element satellites were decommissioned in 2012. Presently, there are 27 satellites fully operational, 4 that are non-functional, and one satellite retired from service.
Six additional FOC satellites have finished production and testing phases and are currently stored, awaiting their launch aboard the Ariane 6 rocket.
The manufacturing of FOC satellites was divided into three separate batches by OHB in Bremen, Germany, with support from Surrey Satellite Technology (SSTL) based in Guildford, UK:
- Batch 1: Consisting of 14 FOC units (FM1 through FM14)
- Batch 2: Comprising 8 FOC units (FM15 through FM22)
- Batch 3: Including 12 FOC units (FM23 through FM34)
Concurrently with the completion of Batch 3, development of the Galileo Second Generation (G2G) satellites is underway by Thales Alenia Space and Airbus Defence and Space. These next-generation satellites will incorporate electric propulsion systems, improved navigation signals, inter-satellite communication links, and capabilities for in-orbit reconfiguration, with deployment anticipated starting in 2027.

Satellites
The first batch of twenty-eight satellites were named in honor of winners from the European Commission's Galileo drawing contest, which selected one child representative from each EU member country.
