The present invention relates to a system for simulating underwater acoustic communication based on ground wireless communication and a method thereof, which can effectively simulate operating characteristics of underwater acoustic communication necessary for the operation of various marine systems such as an autonomous underwater vehicle (AUV) and an underwater drone on the ground by using ground wireless communication. According to the present invention, the system for simulating underwater acoustic communication based on ground wireless communication comprises: a first transceiving terminal connected to a first device through an internal communication network to, when a data packet transmission request message is transferred from a control module of the first device, transmit a GPS value request signal to a transceiving terminal to which a data packet is to be transmitted, modulate an underwater acoustic communication simulation signal in accordance with transmission characteristics of underwater acoustic communication estimated by using a GPS value received from the transceiving terminal, and transmit a data packet to the transmitting terminal through the modulated underwater acoustic communication simulation signal; and a second transceiving terminal performing ground communication with the first transceiving terminal, and connected to a second terminal through an internal communication network to receive a data packet transmitted from the first transceiving terminal to transfer the data packet to a control module of the second device.

    본 발명은 지상 무선 통신 기반 수중음향통신 모사 시스템 및 그 방법에 대한 것이다. 본 발명에 따른 지상 무선 통신 기반 수중음향통신 모사 시스템은 제1 기기와 내부 통신망을 통해 연결되어 상기 제1 기기의 제어모듈로부터 데이터 패킷 송신 요청 메시지가 전달되면, 데이터 패킷을 송신하고자 하는 송수신 단말에 GPS 값 요청 신호를 송신하고 상기 송수신 단말로부터 수신한 GPS 값을 이용하여 추정된 수중음향통신의 전송 특성에 따라 수중음향통신 모사 신호를 변조하고, 상기 변조된 수중음향통신 모사 신호를 통해 상기 송수신 단말에 데이터 패킷을 송신하는 제1 송수신 단말; 및 상기 제1 송수신 단말과 지상 통신하고, 제2 기기와 내부 통신망을 통해 연결되어 상기 제1 송수신 단말로부터 전송된 데이터 패킷을 수신하여 상기 제2 기기의 제어모듈에 전달하는 상기 제2 송수신 단말을 포함한다.
