Time Transfer by IRIG-B Time Code via Dedicated Telephone Link

Abstract

Measurements were made of the stability of time transfer by the IRIG-B code over a dedicated telephone link on Hydro-Quebec's microwave system. The short-and long-term Allan Variance was measured on both types of microwave system used by Hydro-Quebec, one of which is synchronized, the other having free local oscillators. The results promise a time transfer accuracy of 10 microseconds. The paper also describes a prototype slave clock designed to detect interference in the IRIG-B code to ensure local time is kept during such interference.
