Abstract:

Over the last twenty years, the Global Positioning System GPS has revolutionized the performance and the geographical availability of time and frequency dissemination, while at the same time reducing the cost to the individual user. This paper examines the question of what comes next for time and frequency dissemination. The question has two motivations How can improved performance be achieved in the future, and how can redundant sources of time and frequency be provided to critical systems A model is developed for time and frequency dissemination based on the time management performed in GPS. Several candidate systems for future time and frequency distribution are identified. One system-SONET telecommunications is discussed in detail. Performance requirements and hardware implementations are presented.
