Formulation of the problem. In the conditions of radio suppression of subscriber receivers of satellite navigation systems of small-sized unmanned aerial vehicles, it is required to determine their location by linear-frequency-modulated signals of radio engineering beacons.

Target. Substantiation of the functioning algorithm of the short-range radio technical system for unmanned aerial vehicles of a small class, based on the reception of an omnidirectional antenna of broadband signals with low peak power, emitted by space-separated ground radio technical beacons.

Results. An algorithm for the functioning of an on-board device of a short-range radio engineering system for a small-class unmanned aerial vehicle with an omnidirectional antenna is proposed, which ensures its location based on autocorrelation processing of broadband linear-frequency-modulated navigation signals. Analytical expressions are obtained for the values of the mutual difference frequencies of the sum of linear-frequency-modulated signals after their autocorrelation processing. As a result of the simulation of the algorithm, the accuracy of determining the location of an unmanned aerial vehicle was estimated at various values of the radial speed and power of radio beacon transmitters.

Practical significance. The proposed radio technical short-range navigation system provides location determination of small unmanned aerial vehicles with an accuracy that allows performing navigation tasks in conditions of radio jamming of subscriber receivers of global satellite navigation systems.
