Analysis of Galileo satellite navigation system

Along with the application of GPS system in all of fields, the European Union (EU) also understands it is very important that it holds a satellite navigation system by itself. Through a long-time discussion, the informal agreement was subscribed by some countries in EU on 26th March 2002, the new satellite navigation system will be founded by EU, this project was named as Galileo system. China began to discuss with EU at the beginning of this project, for finding some opportunities to cooperate with EU on this project. Now, some agreements have been made, China-Europe Global Navigation Satellite System Technical Training and Cooperation Centre (CENC) was founded on 18th Sep. 2003 in Beijing. In this paper, some concepts will be introduced and analysed at the beginning of this project, including its design frame, its characteristics and its correlative technologies. Some basis will be provided for the future application of Galileo system.
