Abstract : The highly stable propagation characteristics of VLF transmissions make them an ideal source of world-wide navigation data. The arrival phase of a VLF signal is continuously compared with a local standard. The change in the phase difference between the received signal and the local standard is converted to relative motion with respect to the VLF transmitter. This investigation concerns itself with the development as a whole of the VLF navigation system. Refinements are made in the antenna system and the antenna signal processing. In addition, navigation procedures, tables, and forms are presented for system use. (Author)
