Which device on a UAS relays information about RPM, position, altitude, airspeed, video images and GPS data?

• A. Receiver
• B. Antenna
• C. Sensor
• D. Transmitter

Answer: (D)

The device that sends all the drone’s data to the operator is the transmitter. Onboard the UAS, sensors and systems gather RPM, GPS position, altitude, airspeed, and the camera captures video. That information is packaged and sent out through the transmitter over the radio link to the ground control station. The antenna simply radiates or receives the signal, not the data itself. A sensor is the source of the data, not the relay mechanism, and a receiver would be on the ground (or the other end of the link) to receive what the transmitter sends. So the transmitter is the component that relays RPM, position, altitude, airspeed, video images, and GPS data.
