Abstract :
The author describes the long wavelength propagation model of the Naval Ocean Systems Center. This model applies the concept of the Earth-ionosphere waveguide to very low frequency (10-30 kHz) and low frequency (30-60 kHz) radio propagation. The propagation model is a collection of computer programs that are exercised separately or in sequence, depending on the application. The execution of these individual programs for purposes of obtaining coverage maps is set up by a driver program, which automates the process. At the present time this driver program implements the sequencing of the programs via the VAX VMS control language
