Method for detecting tampered or counterfeited GNSS signals

The invention relates to a method for identifying a tampered or counterfeited GNSS signal, comprising at least the following steps: a) receiving a GNSS signal; b) analysing the GNSS signal in order to determine at least one signal characteristic and at least one satellite characteristic from the GNSS signal; c) comparing the determined at least one signal characteristic with at least one known signal characteristic, which is specified in accordance with the identified at least one satellite characteristic; d) identifying a tampered or counterfeited GNSS signal if there is a difference between the determined signal characteristic and the known signal characteristic. 本发明涉及一种用于识别篡改或伪造的GNSS信号的方法，至少包括以下步骤：a)接收GNSS信号；b)分析GNSS信号，以便从GNSS信号中确定至少一个信号特性和至少一个卫星特性；c)将所确定的至少一个信号特性与至少一个已知的信号特性进行比较，该已知的信号特性根据识别到的至少一个卫星特性规定；d)如果在所确定的信号特性和已知的信号特性之间存在差异，则识别出篡改或伪造的GNSS信号。
