Brandywine Communications won the subcontract for building the Frequency and Time Subsystem (FTSS) for the advanced satellite terminals under the U.S. Army’s Modernization of Enterprise Terminals (MET) program, managed by the Project Manger, Defense Communications and Army Transmission Systems (PM DCATS) in Ft. Monmouth, NJ. Brandywine’s network-centric advanced time and frequency subsystem provides the U.S. army with a hardened, high reliability, high availability source of ultra accurate frequency and time. The FTSS utilizes redundant cesium frequency standards that are automatically calibrated and synchronized by comparison to a SAASM GPS receiver (Brandywine PTS-SAASM).
These Primary Reference Standards (PRS) in turn are used to drive an advanced modular distribution system, based on Brandywine’s High Performance Timing System (HPTS). This frequency and time distribution amplifier provides hitless reference switching and generates a wide variety of low phase noise outputs to the customers’ specifications.
The system is supported by Redundant Battery Backup Units. The Battery backup units include Ethernet monitoring of battery condition and charge discharge currents. The FTSS also includes and an advanced synchronization control panel that allows both automatic and manual synchronization to a variety of internal and external sources.
A key feature of the FTSS is that the entire system can be remotely managed and controlled using Ethernet interfaces via Simple Network Management Protocol (SNMP). All internal equipment items are individually network-managed, allowing the customer to build the FTSS into a high level Network Management System.
