THE SPOTLIGHT

Brandywine Communications ships first advanced Satellite Ground Station Time and Frequency Subsystem.

Brandywine’s network-centric advanced time and frequency subsystem provides a government customer with a hardened, high reliability, high availability source of ultra accurate frequency and time.

The TFSS 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’ specification.

Available low noise output frequencies are 0.1 MHz ,1 MHz, 5 MHz, 10 MHz, 50MHz, 70MHz, 100 MHz. Available timing outputs are 1PPS, Have Quick, IRIG B, IRIG A, Network Time Protocol (NTP).

A key feature of the TFSS 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 TFSS into a high level Network Management System.

AROUND THE CLOCK

Brandywine delivers first articles for ENTA-R Time Distribution Unit

This time Distribution Unit external receives time of day from two GPS receivers, and provides 1PPS and Have Quick time code to multiple users in different electrical formats. Dual Ethernet ports provide management and NTP functions.  For more information, just click here.

GPSDO

Brandywine’s GPSDO GPS Disciplined Oscillator module provides multiple low phase noise frequency outputs for embedded satellite communications terminal.  The GPSDO is designed to meet the requirements of MIL-STD-188-114 for frequency references. The GPSDO includes options for Ethernet NTP and management capability, which are unique in this class of product.
