Satellite Time and Frequency Transfer and Dissemination


image of Satellite Time and Frequency Transfer and Dissemination

This is the first ITU Handbook to provide detailed information on the applied methods, technologies, algorithms, data structure and practical use of frequency and timing signals provided by satellite systems.




Long time ago people have marked time by the movement of the sun and other stars, by phases of the moon, by the changing of seasons, and by the passing of generations. Time intervals have been measured by sandfilled hour glasses, water clocks, and mechanical devices. The frequencies of musical instruments are tuned by comparison to tuning forks and pitch pipes.
