摘　　要：全球导航卫星系统(GNSS)提供的低能级射频(RF)导航信号,易受到RF干扰的影响而导致导航精度的降低或者接收机的完全失锁。本文介绍了GNSS干扰的类型、技术手段和实施方式。针对不同干扰所采用的抗干扰技术,分析了其优缺点和适用范围。利用多种抗干扰技术初步设计了一个抗干扰方案。The global navigation satellite system（GNSS）provides low energy level radio frequency（RF） navigation signal,which is easy to be affected by the interference of RF,which leads to the decrease of the navigation precision or the complete loss of the receiver This paper introduces the types,technical means and implementation methods of GNSS interference.The advantages and disadvantages and the application range of anti interference technology used in different jamming are analyzed. An anti interference scheme is designed by using various anti interference techniques.
