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.
