downlink
Quick Summary
A downlink refers to a communication channel used for receiving transmissions from a spacecraft or satellite, or the transmissions themselves. It can also describe the act of transmitting data from a spacecraft or satellite to a receiver on Earth. In satellite communications, the downlink is the link from the satellite transmitter to a terrestrial receiver. This is a crucial part of the two-way communication process, where signals are sent from Earth to a satellite (uplink), and then retransmitted back to Earth (downlink). These transmissions can carry various types of information, including voice, video, and data.1234
