欧洲"伽利略"导航卫星

卫星导航系统用途广泛。目前全球主要的卫星导航系统有美国的GPS和俄罗斯的GLONASS。GLONASS因俄罗斯经济等方面的问题，无力补网，系统降效运行，主要用于军事；GPS军民两用，市场规模大，但由于是军方控制，对用户的安全使用具有潜在威胁。“伽利略”卫星导航系统组网布局更加合理先进，采用开放的市场运作模式，具有非常诱人的应用前景。

European "Galileo" Navigation Satellite

Satellite navigation system can be widely used. At present, there are two main satellite navigation systems in the world, namely GPS of USA and GLONASS of Russia. Because of the economic problems of Russia, the GLONASS network cannot be recovered, the system operates in lower efficiency and it's mainly for military use; with large market scale, GPS is for both military and civil use, but because it is controlled by the army, it has a potential threaten to customer's safe use. The networking of Galileo" satellite navigation system is more rational and advanced and it adopts an open market operation mode, so it has a good application prospect.
