  • Patent number: 10303164
    Abstract: A remote control device for an unmanned helicopter includes an orientation sensor that detects a flight orientation of the unmanned helicopter, a GPS antenna and a GPS receiver that detect speed information of the unmanned helicopter, and a CPU that detects a flight distance of the unmanned helicopter by integrating the speed information. A memory stores information concerning a base point of the unmanned helicopter. Based on a flight orientation of the unmanned helicopter and a flight distance of the unmanned helicopter, which is obtained by integration of the speed information, the CPU determines a relative position, which indicates a position of the unmanned helicopter with respect to the base point, and controls the flight of unmanned helicopter based on the relative position.
