The invention discloses a method and a device produced by a satellite simulating signal and belongs to the satellite signal simulation technical field. The method produced by the satellite simulating signal comprises the following steps: receiving simulation coefficients input by users, acquiring navigation message coefficients based on the simulation coefficient; acquiring baseband signals of the satellite simulating signals based on the navigation message coefficients; and starting medium frequency carrier wave modulation for the baseband signals, and acquiring digital medium frequency signals; wherein the simulation coefficients comprise a simulation time, a satellite navigation system, a carrier-receiving coordinate, carrier-receiving moving state coefficients, an interfering type, an ionized layer or a tropospheric delay. By receiving the simulation coefficients input by the users, the method and the device produced by the satellite simulating signal acquire the navigation message coefficients, and acquire the baseband signals of the satellite simulating signals based on the navigation message coefficients, and enable the baseband signals and the digital medium frequency signals to start the medium frequency carrier wave simulation and to acquire the digital medium frequency signals, so that the users can use the baseband signals, or the digital medium frequency signals based on requirements.
