In accordance with the present invention, provided is a radio wave positioning system (10) for an automated aerial vehicle, including at least one base station (100), and an automated aerial vehicle (200) performing wireless communication with the base station (100). The base station (100) includes: a first receiving part (110) receiving a query signal from the automated aerial vehicle (200); and a response signal transmitting part (120) transmitting a response signal to the received query signal. Moreover, the automated aerial vehicle (200) includes: a query signal transmitting part (210) transmitting a query signal to the base station (100); a second receiving part (220) receiving a response signal from the base station (100); and a position measurement part (240) measuring a relative position of the automated aerial vehicle (200) to the base station (100) based on a distance to the base station (100) calculated based on a reception time of the received response signal. Accordingly, the present invention can improve the accuracy of the position measurement of the automated aerial vehicle.

    본 발명은 한 개 이상의 기지국(100); 및 상기 기지국(100)과 무선통신을 수행하는 무인항공기(200);를 포함하는 무인항공기용 전파측위시스템(10)을 제공한다. 상기 기지국(100)은 상기 무인항공기(200)로부터 질의신호를 수신하는 제1수신부(110); 및 상기 수신한 질의신호에 대한 응답신호를 송신하는 응답신호송신부(120);를 포함하여 구성된다. 또한, 상기 무인항공기(200)는 상기 기지국(100)에 질의신호를 송신하는 질의신호송신부(210); 상기 기지국(100)으로부터 응답신호를 수신하는 제2수신부(220); 및 상기 수신한 응답신호의 수신시간을 기초로 산출된 상기 기지국(100)과의 거리를 기반으로 기지국(100)에 대한 무인항공기(200)의 상대위치를 측정하는 위치측정부(240);를 포함하여 구성된다. 이에, 본 발명은 무인항공기의 위치측정 정확도를 향상시킬 수 있다.
