全球导航卫星系统日益增长的经济重要性使心怀恶意的人能够在位置和时间估计方面误导接收者。这可以通过将信号替换或叠加到真实的GNSS卫星信号来实现，并且被称为欺骗。大多数当前的接收器并不设计为检测欺骗。本文旨在系统地阐述威胁。在许多情况下，它们可以通过将接收到的信号、估计的状态以及它们各自的动态与模型进行比较来解决。导航电文的加密签名将进一步提高伪造合成信号的可检测性，并应在新的全球导航卫星系统信号的定义中加以实施。一般来说，欺骗的分析应该得到与自然损伤分析相同的关注。我们希望本文件将有助于实现这一目标。版权所有（C）2014航海学院。
The growing economic importance of Global Navigation Satellite Systems (GNSS) makes it rewarding for malevolent people to aim at misleading receivers in their position and time estimation. This can be achieved by replacing or superposing signals to the authentic GNSS satellite signals and is called spoofing. Most current receivers are not designed to detect spoofing. The present article aims at a systematic exposition of threats. In many cases, they can be addressed by comparing the received signals, the estimated states, and their respective dynamics against models. A cryptographic signature of the navigation message would furthermore improve the detectability of fake synthetic signals, and should be implemented in the definition of new GNSS signals. In general, the analysis of spoofing should receive the same attention as the analysis of natural impairments. We hope that the present paper will contribute to achieve this.
