Modems

Modems are devices that modulate and demodulate signals to transmit digital information over analog communication channels. In the context of space and astronautical engineering, modems are used to transmit data between spacecraft and ground stations or between spacecraft in space. Modems are essential for communication in space missions, as they enable the transmission of telemetry data, scientific data, and commands between spacecraft and ground stations. Modems used in space missions are designed to operate in harsh environments, with radiation-hardened components and advanced error-correction algorithms to ensure reliable communication. The development of high-speed modems has enabled faster data transfer rates, allowing for more efficient communication between spacecraft and ground stations.
