Methods of creation of digital multi-channel transmitters for simulators of signals of radio navigational systems with use of digital signal processing at several speeds are considered. Methods of simulation of the doppler effect arising in case of movement of subjects of navigation by the smooth speed control of phase manipulation and the frequency detuning of carrier frequency are considered.
