Question

How do you describe the complete signal path of the satellite communications operation?

• A. Begins at a ground station, proceeds to an uplink, then to a downlink, and ends at a receiving ground station.
• B. From the satellite, to a downlink, then to a ground station
• C. Begins at a ground station, proceeds to an uplink, to the satellite itself, to a downlink, and ends at a receiving ground station
• D. All of these

Answer 1

Answer: (C)

Begins at a ground station, proceeds to an uplink, to the satellite itself, to a downlink, and ends at a receiving ground station

A communication satellite works like a relay station where signals transmitted by the ground stations are picked up by the satellite's receiver antennas(uplink), the signals are filtered, their frequency changed and amplified, and then routed via the transmit antennas(downlink) back down to Earth.
