Abstract

Conmutador de distribución de tiempo.#Se divulgan sistemas y procedimientos para detectar el fallo de una fuente de tiempo de precisión usando una fuente de tiempo independiente. Adicionalmente, se divulga la detección del fallo de una fuente de tiempo de precisión basada en GNSS basándose en una localización calculada de un receptor GNSS. Además, el sistema puede estar adicionalmente configurado para distribuir un tiempo, derivado de la fuente de tiempo de precisión, como referencia de tiempo de precisión para dispositivos dependientes del tiempo. En el caso de un fallo de la fuente de tiempo de precisión, el sistema puede estar configurado para distribuir un tiempo, derivado de una segunda fuente de tiempo de precisión, como señal de tiempo de precisión durante un periodo de aplazamiento.
