The private sector failed funding the European navigation system, rival from the US GPS system. So the European Commission has decided to directly fund the project with public budget, but it will generate additional delays. The goal is now to have an operational system with 30 satellites by 2012 (instead of 2008). In the meantime, the US will launch a new generation and China is also trying to launch a home-made system. Do Galileo actors share the same strategy and the same goals? It is perhaps the first question to answer!
