Underground RFID navigation requires high reliability of RFID equipment. However, during the operation of the system of non-contact binding to the underground track, there were cases of missing reading tags. One of the reasons for missing tags is the effect of attenuation drift in the high-frequency path between the transceiver and the antenna of the leading car. The RFID-channel monitoring method developed by the authors under the conditions of an electric depot is not suitable for such monitoring when the train is operating on the subway line. Therefore, this article proposes a method that uses the received signal strength indicator when the train is on the line and allows to monitor the current state of the high-frequency path of the SNCBT system.

Key words:
