Abstract
Sistema de navegación, que se caracteriza porque comprende una antena fija de red cuya alimentación es controlada de manera que el haz directivo que sale de esta antena ocupa sucesivamente una diversidad de posiciones; medios para extraer de los espectros correspondientes a cada una de las citadas posiciones frecuencias que, combinadas, dan tres frecuencias correspondientes a las coordenadas de velocidad, respecto al suelo, del vehículo en el que se halla montado el sistema; medios para determinar con ayuda de estas tres frecuencias la velocidad con relación al suelo.
