Launchpad: Time and frequency server accurate in all conditions

September 21, 2016  - By

The VersaSync is a new generation time and frequency server from Spectracom. The high-performance GNSS master clock and network time server delivers accurate, software-configurable time and frequency signals in all circumstances, including GNSS-denied environments.

versasync-spectracom-wIt is based on a platform-approach to maximize versatility without restricting performance, which maintains or improves high-performance standards from larger form factors while reducing the footprint. The result is a rugged and compact design suitable for air, land or sea applications.

Standard VersaSync configurations are designed in accordance to VITA 75, which was developed for easy integration of subsystems in mobile platforms. The overall volume is under 1 liter, the weight is less than 1 kilogram, and its power consumption is approximately 10 watts.

The list of design features for harsh environmental conditions include mil-performance circular connectors, a sealed enclosure (IP65), and an efficient heat transfer via the conduction-cooled based plate. Spectracom is currently confirming its extensive reliability and compatibility modeling to military specifications.

Versatility is also the theme for the VersaSync’s internal time-base, compatibility with external time and frequency reference sources, and time and frequency signal generation. It is available with a choice of a very low-phase noise ovenized crystal oscillator (OCXO) or chip-scale atomic clocks (CSAC), and can accommodate other high-precision internal time references. Similarly, it is available with various GNSS receivers including multi-constellation receivers and SAASM encrypted GPS with an upgrade path to M-code.

Software-defined digital timing I/Os offer mission-to-mission configurability of virtually any timing signal. Network synchronization and management also offers a high degree of flexibility. Two gigabit Ethernet interfaces are available for network synchronization protocols (NTP and PTP) as well as for configuration, status, logging and upgradability.
