| 摘 要： | 最近几次大的局部战争中，全球定位系统GPS（Global Positioning System）受到了越来越多的关注，它已经成为现代战争的又一块重要领域。即使在民用领域，从天上飞行的航班、地上急驰的车辆、海上游弋的船只到宏物小狗脖子上戴的跟踪器，GPS是无时无刻都在发挥着重要作用。目前，欧共体兴致勃勃地组建Galileo导航系统，并希望能在未来的全球导航卫星系统GNSS（Global Navigation Satellite System）唱主角。我国在2000年也成功发射了两颗“北斗“导航试验卫星。这些再加上俄罗斯那苦苦支撑的GLONASS，使得GPS发展及其相关议题变得越来越引人注目。本文重点介绍了一些针对GPS干扰的措施和技术，指出了这些措施和技术的优点和不足。另外，GPS系统构成、工作原理及干扰形式在此亦有所涉及。

| Abstract: | During the local area wars in rencent years, GPS was given more and more attention. It has been a new and critical area in the modern war. Even in the civilian area.it also shows great potential. Today,the Europe committee makes every effort to develop Galileo navigation system, and hopes to be a main role in the future GNSS. China also successfully launched two Beidou experimenntal navigation satellites. Adding the GLONASS of Russia,all these make topics on GPS attract great interest. This paper mainly introduces ways and techniques on GPS anti-jamming,and points out their advantages and disadvantages, also,the system architecture and work theory of GPS are concerned. |
