Communications blackout — Not to be confused with radio silence or news blackout. In telecommunications, communications blackouts are a cessation of communications or communications capability, caused by a lack of power to a communications facility or to… … Wikipedia
Sudden Ionospheric Disturbance — A sudden ionospheric disturbance (SID) is an abnormally high ionization/plasma density in the D region of the ionosphere caused by a solar flare. The SID results in a sudden increase in radio wave absorption that is most severe in the upper… … Wikipedia
Meteor burst communications — Meteor scatter propagation as used by SNOTEL Meteor burst communications (MBC), also referred to as meteor scatter communications[1], is a radio propagation mode that exploits the ionized trails of meteors during atmospheric entry to establish… … Wikipedia
EME (communications) — Earth Moon Earth, also known as moon bounce, is a radio communications technique which relies on the propagation of radio waves from an earth based transmitter directed via reflection from the surface of the moon back to an earth based receiver.… … Wikipedia
high-frequency (HF) communications — The communications carried out at frequencies between 3 and 30 MHz. HF waves are dependent mostly on reflected sky waves and are affected by ionospheric conditions. HF is used for long range communications. The lower frequencies in this range are … Aviation dictionary
