Firstly, the unmanned aerial vehicle pilot inputs a certain voice by using the GC voice input device of the GC voice communication system, and the GC voice input device converts the unmanned aerial vehicle pilot voice into an analog voice signal by using a GC like a microphone. A voice input device is used to convert an unmanned aerial vehicle pilot's voice into an analog audio signal by expressing the strength and weakness of the driver's voice as a voltage change.

Step ii) converts the analog voice signal of the unmanned aerial vehicle pilot processed in step iv) into a digital voice signal in a GC-analog-to-digital converter (ADC), and converts the digital voice signal in a GC-wave generator. Generating a radio wave having a predetermined frequency, and transmitting a radio wave including the digital voice signal using a GC transmitter and having a constant frequency, the GC-analog-digital converter (ADC) The process of converting a voice-converted analog voice signal into a digital voice signal converts an audio signal of an unmanned aerial vehicle pilot encoded in an analog manner into a digital voice signal, thereby converting a digital voice signal including an unmanned aerial vehicle pilot's voice into an unmanned aerial vehicle. All together with digital signal information of main communication, video communication and preliminary communication for control It is possible to obtain an effect that can be transmitted to the unmanned aerial vehicle, and to facilitate compatibility with the unmanned aerial vehicle pilot UI, the GC communication control module, and the GC information database of the digitized ground control (GC) system 10. .

Iv) transmitting a radio wave containing the analog voice signal and having a predetermined frequency using a UAV transmitter, as opposed to the GC-Analog-to-Digital Converter (ADC) of the step GC voice communication system. A UAV-Digital-Analog Converter (DAC), which performs the function of converting the digital audio signal of the step ⅲ) into an analog voice signal, converts the analog voice signal (signal wave) converted in an analog manner into an oscillator ", The process of transmitting to the ACC voice communication system of the ATC system 30 using the UAV-wave generator consisting of a modulator, a frequency converter, and an amplifier. To be carried out. That is, ① a process of making a carrier having an analog voice signal by combining the analog voice signal and the carrier by receiving the analog voice signal converted by the UAV-Digital-Analog converter and the carrier generated by the oscillator " modulator "; (2) the carrier having the analog voice signal of step (1) includes an analog voice signal in a frequency converter and is adjusted to a radio wave having a predetermined frequency; and (3) includes the analog voice signal of step (2) and has a constant frequency. The radio wave includes an analog audio signal whose output is raised through an amplifier "and is generated as a radio wave having a predetermined frequency in the same process as the step ii).
