WebOct 6, 2024 · At its simplest, space communications relies on two things: a transmitter and a receiver. A transmitter encodes a message onto electromagnetic waves through modulation, which changes properties of the wave to represent the data. These waves flow through space toward the receiver. WebMar 28, 2024 · The transmission of information through sky waves is called sky wave propagation (or communication). Sky wave transmission is suitable for frequencies in the range 2 MHz to about 20 MHz. Above 30 MHz, the ionosphere does not reflect the waves; they are transmitted through it. Space Wave Propagation

WebSky Wave Used for the propagation of EM waves with a frequency range of 3 – 30 MHz. Make use of the ionosphere so called due to the presence of charged ions in the region of about 60 to 300 km from the earth surface.
