Carrier Wave
In space and astronautical engineering, a carrier wave refers to a type of electromagnetic wave that is modulated with an information-bearing signal to carry information from one place to another. It is used in various communication systems, including satellite communication, radio communication, and radar systems. The carrier wave is typically a high-frequency sine wave, and the information-bearing signal is added to it by modulating its amplitude, frequency, or phase. The carrier wave is then transmitted through space and received by a receiver, which demodulates the signal to extract the original information. Carrier waves are used in space and astronautical engineering to enable communication between spacecraft and ground stations, as well as between different spacecraft.
