The comparative analysis of possibilities of a fixing of sources of radio emissions from one point is carried out by known methods. Possibility of defining range to a radio emission source under the characteristic of an electromagnetic field, surface of equal phases, is investigated. Ratios are given and possibility of a fixing of sources of radio emissions decameter wave band under the characteristics of curvature of ground electromagnetic wave front in a receiving point is proved. The expressions characterizing spherical front of a radio wave, depending on directing in a horizontal plane, to a source of radio emission and rage to it are received. The composition and structure of five-mast antenna system for definition of range to a source of radio emission and the block diagram of the device, realizing method offered, are defined. The developed device is essentially new one of defining a place of a source of radio emission from one point in decameter wave band. The device allows to define a place of a source of radio emission on ranges of ground radio wave emissions (up to 400 km).
