Q: What was the purpose of Galileo In-Orbit Validation?

A: Galileo In-Orbit Validation (IOV) was designed to test and validate the technologies and systems of the Galileo navigation constellation before the full operational deployment began in 2011.

Q: Who operated the Galileo IOV satellites?

A: The Galileo IOV satellites were operated by the European Union Agency for the Space Programme (EUSPA).

Q: What came before and after Galileo IOV?

A: The Galileo IOV phase followed the GIOVE test satellites and was succeeded by the Galileo Full Operational Capability (FOC) phase.

Q: Which companies manufactured the Galileo IOV satellites?

A: Astrium was the primary manufacturer, while Thales Alenia Space handled assembly, integration, and testing.

Q: How many Galileo IOV satellites were launched?

A: Four Galileo IOV satellites were launched: GSAT0101, GSAT0102, GSAT0103, and GSAT0104 (the latter was decommissioned).
