FIELD: radio engineering, communication.
SUBSTANCE: subset of the demodulated navigation signals accepted by the server is selected to be synchronized with the bit client frames to provide the synchronized bit server frames, the feature of the synchronized bit server frames is calculated to provide a set of the server signature, the set of the client's signatures and the set of the server signatures are compared to provide the comparison result, and the location of the client's device is authenticated on the basis of the said comparison result.
EFFECT: providing the client's device authentication in environments with a low signal-to-noise ratio.
