Abstract

The present disclosure provides a remote control, a terminal, and an on-board device. The control unit of the terminal obtains the current position of the ship and the current position of the terminal in response to receiving an input of an operation for controlling a predetermined propulsion force of the ship. The control unit of the terminal calculates the relative distance between the ship and the terminal based on the current position of the ship and the current position of the terminal. The control unit of the terminal determines a predetermined control amount of the propulsion force based on the calculated relative distance. The control unit of the terminal transmits a remote signal including an instruction for controlling the predetermined propulsion force in accordance with the determined control amount to the ship.
