Abstract:	The Egyptian Satellite Company and the National Institute for Standards (NIS) in Egypt, with technical assistance from the National Institute of Standards and Technology (NIST) in the United States, are collaborating to broadcast frequency and time information to North Africa and the Middle East Region from a Nilesat geostationary satellite. The Nilesat Direct-toHome broadcasts of television and radio programs include a Time and Frequency broadcast, enabling users to recover traceable Time and Frequency with existing antenna and receiver technology. The broadcast includes a stabilized reference carrier frequency, a modified IRIG – B time-code, and an audible time-of-day announcement. This paper discusses the architecture and scope of this system.
