Abstract

Receptores auxiliares de navegación, adaptados para utilizar las transmisiones de un sistema transmisor auxiliar de navegación del tipo en cuestión, caracterizado porque el receptor comprende una serie de secciones receptoras, alimentada cada una de ellas con una frecuencia diferente de una serie de frecuencias asignadas recibidas de dicho sistema; una serie de osciladores, uno en cada sección, y todos de la misma frecuencia nominal, igual a un submúltiplo de la frecuencia básica denominador común del sistema; medios conmutadores cronometrados; medios controlados por estos conmutadores cronometrados y destinados a controlar el oscilador en cada sección en relación de enclavamiento respecto a las señales de frecuencia asignada aplicadas a aquella sección durante tiempos en que dichas señales se hallan presentes en la citada sección y para controlar dicho oscilador en relación de enclavamiento respecto a las señales de dicha frecuencia submúltiple en otros momentos, derivándose la referidas señales de frecuencia submúltiple de señales que se reciben en los otros momentos citados; y medios que responden separadamente a la relación de fases entre oscilaciones del oscilador de la sección a que se aplica la frecuencia asignada a la estación maestra del sistema, y oscilaciones de cada uno de los osciladores de las secciones a que se aplican las frecuencias de las estaciones esclavas del sistema, para dar indicaciones sobre líneas de posición hiperbólicas.
