What is downlink referred to as?

• A. Used to describe the frequency received from the satellite.
• B. Used to describe the frequency transmitted to the satellite.
• C. Used to describe the data rate
• D. Used to describe the satellite orbit

Answer: (A)

Downlink refers to the signal path from the satellite back down to the ground and is the frequency the ground station uses to receive that signal. It’s the “receive” side of the link. The opposite direction—transmitting from ground to satellite—is the uplink, described by a different frequency. Data rate and the satellite’s orbit are separate concepts and not what downlink denotes. So the downlink is best described as the frequency received from the satellite.
