The application relates to a satellite navigation deception method, system and device based on an intelligent metasurface. The method comprises the following steps: deploying a single or multiple RIS modules fixed on a mobile or fixed carrier between a navigation satellite and a target receiver; according to the ability of the RIS module to reflect or transmit a navigation frequency band signal, using the RIS module to receive and forward a single or multiple real navigation signals, changing the propagation path of the real navigation signal, without storing and processing the navigation signal, and the deployment complexity and cost are low. Furthermore, a signal processing model is constructed according to the signal obtained by the target receiver, and the signal forwarding beam of the RIS module is controlled through the signal processing model, so that the target receiver in a certain area receives a forwarding signal power greater than a real signal power, and the success rate of navigation deception is improved.
