10/25/40 GbE High Performance PTP Grandmaster and NTP Server

PRISMA VelaSync™ high speed time server is a network appliance designed for high frequency trading and other low-latency network applications. The combination of PRISMA’s highly optimized timing protocols and management functions, Spectracom’s precision GPS timing technology and the flexibility of commodity hardware offers exceptional performance and keeps pace with the needs of evolving network infrastructure.

  • PTP + NTP on all ports
  • Low 100’s of nanoseconds accuracy
  • 1G/10G/25G/40G Ethernet
  • I/O support for 1PPS, IRIG
  • Multi-GNSS support (GPS, Galileo, GLONASS, Beidou)
  • Rubidium atomic clock option
  • STL sync option for indoor timing or augment GNSS
  • BroadShield GPS jamming and spoofing detection option
  • Advanced user interface and REST API
  • Secure network management; enable or disable protocols for encryption, authentication,authorization and accounting
  • IPv4/IPv6 dual stack
  • Dual redundant and hotswappable AC power supplies and hard drives


Flexible Configuration Provides Reliable, Secure Time

The PRISMA VelaSync’s web-based user interface simplifies the configuration of multiple time sources for resiliency against GPS jamming or spoofing attacks, network issues and equipment failures. For example, the server can be easily setup to use a PTP source as a backup to the on-board GPS and use an NTP source as a cross check. The servers can be setup to back up each other so that if one fails, the time service continues. It includes dual redundant hot-swap power supplies and 1T hard drives.

And now, with the addition of STL, you can augment GNSS signals or cut the cord altogether with an indoor solution.

Smart Reference Monitoring

The PRISMA VelaSync uses smart reference monitoring to validate the fidelity of all available references. It does this by actively comparing phase offset of each reference against the primary reference and each other. The phase error validation calculates long-term averages and standard deviations of the phase offset between the monitored external reference and the internal system reference. The standard deviation is used to calculate two validity thresholds; a higher and a lower one (the latter acts as a hysteresis buffer, preventing the status flip/flopping if the actual phase error validation value varies closely around the outer threshold).


Security is a priority within the PRISMA VelaSync and included as part of the standard platform. Capabilities include supporting centralized authentication (LDAP, RADIUS, TACACS+), journaled activity logging, secure protocol support (SSH, HTTPS), and more. Updates are generally released on a quarterly basis, but patches and fixes to major CVE’s are addressed as they are discovered.



More Info

Server appliance offers multiple 1GbE (RJ-45), 10GbE (SFP+), 25GbE (SFP28), and 40GbE (QSFP) network ports for set-up, management, and simultaneous NTP and PTP server/grandmaster capability with built-in network sync monitoring.

More Info

New regulations from MiFID II in Europe to the Consolidated Audit Trail in the US mandate that reportable events must be timestamped to much more accurate levels than ever before and that regulated organizations must have a clear understanding of time for all information they are required to report. Europe’s MiFID II, in particular — which came into force on January 3, 2018 — is far more prescriptive with regards to timestamping, as defined by the European Securities and Markets Authority (ESMA) within RTS 25.
