Abstract(in English) | The high frequency band, which is a type of electromagnetic wave, has the advantage of being able to transmit radio waves to the far side of the Earth without the need for relays. This is because high frequency waves propagate through the ionosphere, a layer that covers the Earth in a spherical shape and reflects off the Earth's surface. However, predicting the current state of the ionosphere accurately is difficult because it changes over time and due to sudden phenomena that occur unexpectedly. Currently, the International Reference Ionosphere (IRI) is known as a empirical standard model of the ionosphere. However, actual ionospheric conditions change when solar activity becomes more active. For this reason, this paper uses FT8, a wireless communication method, to study the ionosphere from a new perspective of actual communication data propagated worldwide. Furthermore, the measured data is compared with the theoretical model to verify the requirements for ionospheric propagation and to ensure consistency between them. |
