如今全球卫星导航系统在国防和国民经济各个领域得到了广泛应用。在民用和军事行动方面人们对卫星导 航系统依赖性不断增强，卫星导航领域的竞争也日益加剧。但是卫星通信是一种容易受到干扰的通信体制，因此必须研究一 些有效并且可行的抗干扰方法避免干扰。本文对全球卫星导航系统中通信抗干扰技术和算法进行了一系列的研究，总结了抗 干扰技术的现状和发展趋势。

Now the GNSS has been widely used in various fields of the national economy and national defense. In the civil and military action, the dependence on satellite navigation system constantly enhances. The competition in satellite navigation is also increasingly fierce. The satellite communication is vulnerable to jamming, so it is necessary to study some effective and feasible methods of anti-jamming to avoid interference. This paper conducts a series of researches on communication anti-jamming technology and algorithm of GNSS, summaries the current situation and development trend of anti-jamming technology.
