What is the main function of the transmitter in a UAS?

The main function of the transmitter in an Unmanned Aircraft System (UAS) is to relay status information. This includes sending telemetry data such as altitude, speed, battery levels, and other critical operational details from the aircraft back to the operator. By constantly transmitting this information, the operator can monitor the health and performance of the UAS during flight, allowing for informed decision-making regarding the operation of the drone.

The other options, while related to the broader operation of a UAS, do not accurately reflect the primary role of the transmitter. The control of flight is typically managed through commands sent via a remote control or ground control station but not exclusively through the transmitter. Capturing data is primarily the function of the onboard sensors or cameras rather than the transmitter itself. Providing power relates to the power source of the UAS, which is not the function of the transmitter.
