Time & Frequency System Overview

Modular Time & Frequency Synchronization Platform

SecureSync® combines Spectracom’s precision master clock technology and secure network-centric approach with a compact modular hardware design to bring you a powerful time & frequency reference system at the lowest cost of ownership. Military and commercial applications alike will benefit from its extreme reliability, security, and flexibility for synchronizing critical operations.

  • Synchronize to GPS, SAASM GPS, multi-GNSS and many other timing references
  • Generate virtually any time and frequency output signals
  • Choose from a variety of internal oscillator options
  • Built-in high-performance NTP server; PTP options
  • STL Option - add alternative signals to GPS or GNSS input references to improve resilience, or use STL alone for indoor applications.
  • Modular (configure-to-order) ruggedized shock and vibration-tested chassis (1RU)
  • Exceptional operating temperature range of -20°C to +65°C
  • Secure network management and control
  • Platform approach allows easy integration of specific capabilities
  • Defense Information Systems Agency (DISA): Department of Defense Information Network (DoDIN) Approved Products List (APL) approval of the Spectracom SecureSync Release (Rel.) 5 Tracking Number (TN) 1831001 as a Timing and Synchronization Device (T&S Device). View approval letter.

Success Stories

More Info
When a major national broadcaster set out to update its synchronization infrastructure to provide precise timing and frequency control of its studio operations and broadcast transmissions, their contractor looked to Spectracom to design and install a fault-tolerant 1PPS and 10 MHz distribution system for new digital equipment as well as legacy systems.

More Info
NTP (Network Time Protocol) and SNTP (Simple Network Time Protocol) are very similar TCP/IP protocols in that they use the same time packet from a Time Server message to compute accurate time. The procedure used by the Time Server to assemble and send out a time stamp is exactly the same whether NTP (i.e. full implementation NTP) is being used, or if SNTP is being used.

More Info
Large-scale NTP deployments require consideration for the network’s time synchronization architecture. Network time deployments are usually driven by considerations for reliability, scalability, manageability and security. The capability of modern NTP servers, such as Spectracom SecureSync® and NetClock® time servers, is such that capacity does not impact the design of the synchronization architecture.

White Papers

More Info
Typically, applications for timing use GPS as a precise, traceable, high availability, and free source of synchronization. But GPS is not the only satellite in the sky. More and more Global Navigation Satellite Systems (GNSS) are being developed and deployed. This white paper describes the trend to multi-GNSS using the example of the Russian GLONASS system as a complement to GPS.
