The Naval Space Surveillance Center (NAVSPASUR) is an operational naval command that has the mission of determining the location of all manmade objects in space and transmitting information on objects of interest to the fleet. NAVSPASUR operates a 217 MHz radar fence that has 9 transmitting and receiving stations deployed in a line across southern CONUS. This surveillance fence provides unalerted detection of all satellites overflying CONUS. NAVSPASUR also maintains a space catalog of all orbiting space objects, including payloads, rocket bodies and debris, and distributes information on satellite orbits to the fleet and other users by means of Navy tactical communication circuits and other means. NAVSPASUR. plays an important role as operational alternate to the primary national Space Surveillance Center (SSC) and Space Defence Operations Center (SPADOC) located in Colorado Springs, Colorado. In executing these responsibilities, NAVSPASUR has need of precise and/or standardized time and frequency in a number of applications. These include maintenance of the radar fence references to specification, and coordination with other commands and agencies for data receipt and dissemination. Precise time and frequency must be maintained within each site to enable proper operation of the interferometry phasing technique used. Precise time-of-day clocking must exist between sites for proper intersite coordination. After 'time tags' are attached to the data at the receiver sites, proper referencing and standardization are necessary at the Dahlgren, Va. operations center to ensure proper data synchronization and communications with the fleet and other agencies.
