Ionosphere - Wikipedia

Web14 apr. 2024 · The ionosphere, which reflects HF radio waves, is created by solar radiation and is a part of the space weather environment. The ionosphere extends from around … The ionosphere is a region of the upper atmosphere, from about 80 km to 1000 km in altitude, where neutral air is ionized by solar photons, solar particles, and cosmic rays. When high-frequency signals enter the ionosphere at a low angle they are bent back towards the earth by the ionized layer. Meer weergeven In radio communication, skywave or skip refers to the propagation of radio waves reflected or refracted back toward Earth from the ionosphere, an electrically charged layer of the upper atmosphere. Since it is not limited … Meer weergeven VHF signals with frequencies above about 30 MHz usually penetrate the ionosphere and are not returned to the Earth's surface.
