Аnnotation: Positioning and synchronization of seismic stations using GPS receivers is convenient and has high enough accuracy for subsequent processing and adequate interpretation of the obtained seismic data. However, it is impossible to synchronize the seismic station at the time of data acquisition if it is outside the access area of GPS satellites, for example, in a deep mine in such a way that the receiver itself cannot be pulled out of the mine, leaving it connected to the seismic station. This situation is relevant, for example, for seismological studies conducted by the IGD RAS in Gubkin. This work is aimed at solving the problem of positioning and synchronization of seismic stations directly inaccessible to the signals of satellites of this system.
