One-position correlation goniometric method for determining the coordinates of the location of radio emission sources is based on the measurement of the parameters of the desired source of radio emission (RES) in a single radio control post (RCP) and the calculation of the same parameters at points, the location of which is supposed to be known, is also based on the fact that the azimuth is measured on the RES using a RCP with a logoperiodic rotary antenna system (LRAS), specify the coordinates of the location K of the virtual posts (VPs) on the database of radioelectronic facilities (REF) of the used RCP in the sector of the measured azimuth at a distance of several angular minutes from the RCP, make a list of i base REF (i BREF) located in the measured azimuth sector, calculate the azimuths from the RCP and the VP on i BREF using the position coordinates, establish the correlation of the azimuths (AC) with the VP on i BREF from the azimuths on them with the RCP, make up the i (K+1) ray equations with the VP and with the RCP with the azimuths calculated on i BREF, redefine the BREF coordinates i as the coordinates of the pairwise crossing points of these rays, thus obtaining the K gauge characteristics (GC) for RCP/VP pairs in latitude (LaGC), longitude (LoGC) and azimuth (AGC) as the dependences of the difference between the true and calculated coordinates and azimuths from the corresponding calculated coordinates and azimuths, then calculate the azimuths from each VP on the RES using the measured azimuth ϕ on the RES and the received AC for the pairs of RCP/VP, correct them using AGC, calculate the test coordinates of the RES as the coordinates of the intersection points C 2   k+1  of pairs of rays with RCP and VP for the desired RES, correct them using LaGC and LoGC, averaged and fixed as final. 
     EFFECT: increased accuracy of the definition of PRFES by increasing the number of virtual posts and the use of one RCP.
