摘要:随着计算机技术、通讯技术、航天技术等一系列高新技术的发展，卫星导航定位技术获得了长足的发展，不管是在军事领域还是民用领域都有非常广泛的应用。
我国也建立了自己的卫星导航定位系统，即北斗卫星导航定位系统，并与美国的全球定位系统、俄罗斯的格洛纳斯系统、欧盟的伽利略定位系统成为世界上四大卫星定位系统。这四大卫星定位系统存在着或多或少的差别，但它们的同时存在，既能相互弥补、共同促进，又相互竞争。本文主要对这四个系统的现状进行分析，并横向比较，来预测北斗卫星导航系统的应用前景。

Abstract:With computer technology, communications technology, aerospace technology, the development of a series of high-tech, satellite navigation and positioning technology has achieved great development, whether in the military or civilian fields have a very wide range of applications.
China has also established its own satellite navigation system, satellite navigation and positioning system that Compass, and with the U.S. global positioning system, Russia's GLONASS system, the EU's Galileo positioning system as the world's four major satellite positioning system. That there are four satellite positioning system more or less difference, but they exist, both complement each other and jointly promote, and compete with each other. In this paper, it is to predict the Compass satellite navigation system applications by analyzing the status of these four systems.
