卫星导航信号反欺骗性研究

Analysis of Countermeasures for GPS Signal Spoofing

目前我国正在发展自己的卫星导航系统——北斗卫星导航系统。由于北斗卫星导航系统和GPS有比较高的兼容性,因此借鉴GPS卫星导航系统的成熟经验,可以使我们在应用北斗卫星导航系统的过程中,得到许多有益的启示。将在空间中对GPS导航信号进行反欺骗性研究,通过对GPS卫星导航信号的分析,设想欺骗信号的可能性,并给出相应的对策,提出反欺骗算法。

Now we are developing our own satellite navigation system --the compass satellite navigation system. Because of the compass and GPS are compatible, it can inspire us, if we study the successful experience of the GPS. In this paper, we are going to present anti-spoof research on the GPS signal in space, and analysis the signal of GPS, assume the possibility of spoofing, and then advance the measures and anti-spoofing arithmetic.
