Problem statement. Local radio navigation systems are considered as a zonal alternative to global navigation satellite systems, since they allow solving the problem of coordinate-time provision of users in conditions of inaccessibility of satellite navigation signals. The main disadvantage of local radio navigation systems using rangefinder or differential-rangefinder methods for determining coordinates is the need to ensure that the times of the beginning of the transmission of the alternative coordinate-time signal by the transmitters and the times of their reception in the receiver of the navigation equipment of consumers are bound to the uniform time scale, i.e. to ensure the binding of the time scales of the transmitters and the time scale of the receiver to the uniform time scale, which in itself is a complex technical problem that requires separate communication channels for transmission of synchronization signals to solve it.

Purpose. To develop a method for local radio navigation according to signals of unsynchronized domestic means of electronic jamming of global navigation satellite systems.

Results. The method that provides local positioning of an authorized consumer according to signals from radio interference transmitters that are not synchronized with each other and not synchronized with the navigation equipment of the consumers is proposed. The method is based on the procedure for the initial synchronization of the navigation equipment of consumers with the calculation of corrections taking into account the desynchronism of the time scales of the navigation equipment of the consumers and the interference transmitters, using the known information about the location of the interference transmitters and the coordinates of the initial synchronization point.

Practical significance. Evaluation of the effectiveness of the proposed method was carried out by the method of computer simulation. Studies have shown that for an authorized consumer located at a distance of more than 30 km from the interference transmitters, the radial positioning error did not exceed 200 m with a range measurement error of no more than 30 m.
