Telephony

Telephony is the technology of transmitting voice and data over a distance using telecommunication systems. In space and astronautical engineering, telephony is used for communication between spacecraft and ground stations, as well as between astronauts and mission control. Telephony systems in space must be designed to withstand the harsh environment of space, including extreme temperatures, radiation, and vacuum conditions. Additionally, the distance between spacecraft and ground stations can result in significant delays in communication, which must be accounted for in the design of telephony systems.
