Time and Frequency Synchronization (T&F Sync) Common and Standardized Architecture for DOD Shore Communication Stations; Conference paper

摘要

Time synchronization and frequency syntonization are vital to all mission-critical DOD C4ISR systems to ensure accurate data processing and timely information transmission and reception. Existing Time and Frequency Synchronization (T&F Sync) systems at Navy shore communication stations have evolved over many years and are often unique, stand-alone, site-specific configurations having been implemented for a number of specific system designs to meet a variety of specifications, standards, and requirements. These systems are composed of an eclectic and varied mixture of military and Commercial-Off- The-Shelf (COTS) equipment, many of which are legacy, obsolete, or discontinued models. Under the sponsorship of SPAWAR 05 and PEO C4I & Space/PMW-170 (formerly PMW-156), SSC-SD has evaluated available COTS T&F Sync equipment configurations. These configurations were evaluated for potential operation in accordance with JCS (Joint Chiefs of Staff) requirements, as well as current and future military requirements. From this evaluation the architecture for a common T&F Sync equipment configuration for shore communication stations was determined. Coordination of this proposed architecture with personnel from the sponsoring activities, the Defense Information Systems Agency (DISA) and the Naval Research Laboratory (NRL) has resulted in a final T&F Sync architecture solution that has been proposed for implementation. The proposed architecture is the subject of this paper. The goal of implementing this T&F Sync architecture is to provide a common technical architecture for all DOD shore communication stations that can satisfy current requirements and be expanded to meet future requirements.
