Abstract

In this paper, a method, algorithm, and calculation program are presented to calculate the working frequency for the transmission lines of skywaves. The calculation method allows for improving the accuracy in determining the working frequency by taking into account the inhomogeneities of the ionosphere. The experimental validations showed that the developed program gives high accuracy with and fast calculation time. The probability of successful communication using frequencies calculated by the program is 78%. When using 2 additional frequencies, the probability of successful communication reaches 92%.
