The Launch Readiness Review (LRR) will take place on Wednesday, December 16, 2015 in French Guiana, to authorize the start of operations for the final countdown.

Galileo, an emblematic European program

Galileo, a new global satellite navigation system, is an emblematic European Union program – lead by its Directorate General for Internal Market, Industry, Entrepreneurship and SMEs (GROWTH); with ESA assigned the responsibility for design and procurement.

The Galileo FOC (Full Operational Capacity) satellites are built in Europe by OHB System of Bremen, Germany as prime contractor, with all payloads supplied by SSTL (Surrey Satellite Technology Ltd.), a British subsidiary of Airbus Defence and Space.
