On 9 April the European Space Agency (ESA) reported that the worldwide Ground Mission Segment providing all Galileo navigation messages has completed a full-scale hardware and software migration to version V2.0, and is now fully operational again.

The Ground Mission Segment was turned off on 26 January, allowing the migration to take place over the month of February. The following month was taken up with detailed checking by operations and system, concluding in a final ‘check point’ on 31 March to validate the successful migration.
