How many satellites will Galileo have?

Once the Galileo constellation reaches Full Operational Capability (FOC) it will consist of 30 satellites. The constellation will contain 24 operational satellites and auxiliary satellites not part of the baseline constellation. From most locations, six to eight satellites will always be visible, allowing positions and timing to be determined very accurately to within a few centimetres. Interoperability with other GNSS increases the reliability of Galileo services.

The next launches are planned from late 2021 onwards. In a first phase, this will re-enforce the constellation with the deployment of auxiliary satellites. After this, subsequent launches will be used for constellation replenishment purposes.
