FIELD: radio engineering and communications.
SUBSTANCE: invention relates to radio engineering, and in particular to methods for determining the location of radio frequency source (RFS), and can be used in navigation, direction-finding, location means for determining the location of a user terminal (UT) using radio signals received from a satellite transponder (ST) at low near-earth orbit. Method is based on the location of the complex electronic monitoring (CEM) and M≥2 emitting reference benchmark (ERBM) at positions with known coordinates, specifying the area of radio monitoring (ARM), radiation with the help of CEM equipment and m-s, where m=1…M, ERBM test radio signals at times tn, where n=1…N, N≥3, receiving in a CEM of said test radio signals after their retransmission of ST, determining canonical parameters of ST at time tn, choosing a sphere with a radius calculated on the basis of the average latitude of the ARM as the surface of the earth, and then determining the location of UT on the surface of the earth.
EFFECT: improving the accuracy of determining frequency shifts of system signals.
