What term establishes a communication between the GCS and the UAS?

• A. Transceiver
• B. Datalink
• C. Noise
• D. Redundant and backup systems

Answer: (B)

The key idea is the data channel that connects the Ground Control Station to the UAS. This datalink is the two-way link that carries flight commands from the GCS to the aircraft and returns telemetry and status information from the aircraft to the operator, enabling real-time control and monitoring. It sets how messages are sent, how reliably they’re delivered, and what medium or frequency is used. A transceiver is the hardware that can both transmit and receive signals and is part of the datalink hardware, but it isn’t the name of the communication link itself. Noise refers to unwanted interference that can disrupt the link, and redundant and backup systems describe additional components for safety, not the actual connection between GCS and UAS.
