Abstract
Local generation and distribution of precise, accurate, and stable time and frequency reference signals comprise an essential and central component of the NASA Deep Space Network (DSN). Within each complex, synchronized timing references are required by approximately 100 users located at distances up to 30 km from the central control center and station master clock. In this article, the first of two parts, a highly modular, hot-swappable, and expandable system design for generation, delivery, and synchronization of highly precise and stable timing signals over fiber-optic cables is described. The new timing system is now operational at all three DSN sites—Signal Processing Center 10 (SPC 10), SPC 40, and SPC 60— as well as Cape Canaveral’s MIL-71, the DSN Development and Test Facility 21 (DTF-21), and at several JPL development laboratories. Performance tests and operational experience will be reported in Part II.
