List of Galileo satellites explained

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 IOV "In Orbit Validation" and 28 FOC "Full Operational Capability") satellites have been launched. The 2 GIOVE ("Galileo In-Orbit Validation Element") prototype vehicles were retired in 2012. Currently, 25 satellites are operational, 2 are undergoing commissioning, 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]

  1. Batch 1 consists of 14 FOC satellites (Galileo-FOC FM1 to Galileo-FOC FM14)
  2. Batch 2 consists of 8 FOC satellites (Galileo-FOC FM15 to Galileo-FOC FM22)
  3. 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 2026.[4] [5] [6] [7]

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.
