424The telemetry transceiver system consists of a telemetry transmitter and a telemetry receiver. The telemetry transmitter is installed at the front of the wing propeller, and the telemetry receiver is installed inside the fuselage. After collecting data from onboard sensors, the telemetry transmitter outputs the signal, which is then transmitted out through the telemetry transmitter. After receiving the signal, the telemetry receiver completes signal demodulation, decoding, and outputs the data stream. The telemetry transmitter and telemetry receiver use identical board
