The present invention discloses an autonomous navigation and remote control navigation switching control module of an unmanned ship. The module comprise a combination simulation data selector and an STM32 minimum system. Two one-out-of-eight simulation selectors are combined through a cascade mode to form a two-out-of-four simulation selector to adapt signal selection requirement of a catamaran. The STM32 minimum system is employed to perform capture of PWM signals of a receiver so as to convert the PWM signals to voltage signals required by an unmanned ship. The module can realize switching of autonomous and remote control controlling modes of the unmanned ship, especially when there are emergency situations in a research and development phase and a later period task execution process, experimenters or field operation personnel can timely hold the control power of the unmanned ship because of two control modes so as to ensure that the loss of the unmanned ship configured to carry essential devices is reduced to the minimum, enhance the operation flexibility of the unmanned ship and improve the system reliability.
