The Basics 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.

WebThe radio waves also need to arrive at the receiver simultaneously. All time differences must be corrected for, because in order to receive a strong enough signal so that an object can be properly charted, the received radio waves need to be coherently added up. … WebThe techniques used in radio astronomy at long wavelengths can sometimes be applied at the shorter end of the radio spectrum—the microwave portion.
