Position and time information provided by the satellite navigation system is important in many application fields. However, the satellite navigation signal is vulnerable to interference signals due to the low navigation signal strength. This interference signal for the satellite navigation signal is being advanced to the spoofing signal, which can adjust the position and time information of the satellite navigation receiver, beyond simple jamming signal. To ensure the safe use of satellite navigation signals in the future, it is necessary to prepare for attacks by such spoofing signals. It is possible to reduce the damage to users of satellite navigation by early detection of the spoofing signals. For spoofing signals, the detection method should be applied according to the attack method, and various detection methods should be applied because the impact of the attacker on the receiver may vary depending on the attack method and attack item. In this study, we propose a method to detect the spoofing signal when the signal is induced based on the satellite navigation correction data and measurement value. The proposed detection method is advantageous in that it can be applied to a receiver directly because the spoofing signal can be detected without being equipped with additional hardware in a conventional receiver. Additionally, this method can be applied to a mobile receiver as well as a fixed receiver. It is expected that the proposed technique will increase the usefulness and reliability of the satellite navigation system.
