A real time locator by single station was developed by the use of the dispersion characteristics of VLF and ELF propagation. A remarkable merit of this apparatus is the real time locations of atmospherics, separating ground discharges from cloud discharges. Brief description of the apparatus and preliminary results are mentioned, although it is natural that further studies for improvements are strongly required. © 1974.
