VERSASYNC

Rugged Time and Frequency Reference

VersaSync is a low SWaP high performance GNSS master clock and network time server that delivers accurate, software configurable time and frequency signals under all circumstances, including GNSS-denied environments.

The Miniature Rubidium oscillator option brings outstanding holdover capability, for applications facing persistent GNSS outages.

Its compact size and high level of ruggedization make VersaSync suitable for mobile applications in harsh environments. Its small footprint allows for easy integration of the time and frequency functionality into any systems’ architecture.

The «standby mode» capability allows the unit to maintain precise timescale, while being minimally powered, with time distribution being resumed once main power is reapplied.

VersaSync optionally includes proven GNSS interference detection algorithms (jamming, spoofing), and implements smart time reference management in case of GNSS interference detection.

VersaSync also embeds strong operational cybersecurity, enabling secured time distribution on governmental / defense networks.

Backed by more than four decades of timing solution expertise from Safran, VersaSync includes all the timing functionality required in modern, network-centric applications:

• NTP/PTP precise time transfer over Ethernet, including security protocols that prevent network vulnerabilities

• Low phase noise 10 MHz frequency distribution

• Configurable pulse signals, including IRIG or HaveQuick timecodes

• Serial link Time Of Day (ToD) messages

A Perfect Fit for GNSS-Denied Environments

VersaSync accommodates a wide range of precision oscillators, allowing the unit to maintain frequency and time accuracy for long periods of GPS/GNSS outage. These options include OCXO quartz oscillators and a micro-rubidium option, which brings unprecedented time stability and reliability in such a compact form factor. In addition, it can be re-synchronized by an alternative external reference.

Highly Reliable, Versatile, and Configurable Solution

VersaSync physical inputs and outputs are software configurable and can adapt to various application requirements for mission-to-mission configurability.

I/O pins can be configured as TTL, 10 V pulse, RS232, or RS485. This allows VersaSync to provide a high number of outputs of the same, or different types, while still fitting into a small form factor. However, if the combination of software configurable outputs is not enough, VersaSync can accommodate an option board, designed to customer requirements to provide additional outputs of the standard types or future interfaces.

VersaSync is designed for exceptional intrinsic reliability. Comprehensive status monitoring capability, either locally or remotely, allows quick fault diagnoses. Remote monitoring is based on SNMP protocol and RestAPI, providing flexibility for automated / scripted monitoring. An internal, exportable log can be accessed either locally or remotely.

Future-proof, network-enabled time distribution

VersaSync is a key enabler for network-based migration strategies, and enables precise time distribution to network elements or network-connected sensors, using NTP or PTP protocols - towards sub-millisecond time transfer accuracy. Without any compromise on cyber security
