EGNOS infrastructure was completed in July 2005 and EGNOS passed its first operational readiness review. In 2006, discussions were ongoing to transfer EGNOS to the GSA. The Commission had provided €143 million of funding for the programme under the TEN. In 2007, the re-profiling of Galileo affected EGNOS, expected to enter into service in 2008. EGNOS and Galileo would be merged in a single programme and financed entirely with public funds. The Commission then noted that EGNOS costs were so far estimated at €700 million for the EU and ESA, as well as additional costs of €330 million for the 2008-2013 period. The budget of EGNOS was increased due to unforeseen complexities in the system, and to the fact that the aviation sector requested triple redundancy within the system to ensure back-up in case of the failure of one element. This implied the tripling of the ground infrastructure, increasing the costs.
