In UAS communications, which term describes the data that is transmitted from the ground to issue commands?

• A. Commands
• B. Telemetry
• C. Video data
• D. Sensor data

Answer: (A)

Data flow direction in UAS communications and the term for ground-to-drone control data. The data that travels from the ground to the aircraft to issue commands is called commands. This uplink control data carries the operator’s inputs that drive the UAV’s movements and mode changes, translated by the flight controller into motor commands and actuator actions. Telemetry, video data, and sensor data, on the other hand, are typically sent from the drone back to the ground, conveying status information, imagery, and environmental readings rather than instructions to the aircraft. So the term for ground-to-air commands is simply commands.
