SecureSync is the key enabler of highly available time and Frequency synchronization distribution architecture. It adapts to demanding infrastructure environments, with extended temperature support (-20°C to +65°C). Time distribution to legacy systems can be acheived with a range of synchronization signals, while timing protocols (NTP, PTP) are available for synchronizing of recent systems through the networks.



SecureSync offers a broad range of flexible design options, including a variety of internal oscillators for holdover and phase noise, and onboard clocks that can be synchronized to many external references. The platform can be configured for specific applications, with the ability to extend the number of options cards on the platform (up to six cards can be accomidated per unit).

Option Cards include:

1PPS, Alarm Relay, ASCII Time Code, Event Broadcast, Frequency Output (1, 5, 10 MHz), Gigabit Ethernet, HAVE QUICK, IRIG, Precision Time Protocol (PTP), Square Wave TTL, STANAG, STL and Other Signals, T1/E1 Output, and Programmable Frequency Output.


SecureSync User Interface

SecureSync® offers set-up, configuration and monitoring in a variety of ways, such as the front panel, RS-232 “console” port, or through many network services. However, its feature-rich browser interface provides the greatest access to all available tools.

Interference Detection and Mitigation

SecureSync is built on a scalable, flexible and highly configurable platform to offer precisely what customers need at the lowest cost of ownership. In addition to interference detection, greater resiliency on SecureSync is available through a multi-layered approach that can leverage anti-jam antennas, Orolia’s complete Interference Detection and Mitigation (IDM) suite which includes spoofing detection, as well as time error minimization with high performance internal oscillators. Qualified military customers are also eligible for secure military signals such as SAASM and M-Code.

As an encrypted signal 1000x stronger than GNSS, STL is an ideal solution for augmenting GPS or other GNSS constellations for resiliency and security or as a standalone indoor solution when roof access isn’t an option.


SecureSync Interference Detection Suite

IDM Software Suite Precision Timing Option

SecureSync Interference Detection Suite is an interference detection suite that keeps your GPS/GNSS Synchronization safe from vulnerabilities caused by jamming and spoofing.

Interference detection is a key enabler for greater resiliency in critical infrastructure.

Orolia now offers GPS jamming detection as a standard feature for its flagship SecureSync® time servers. Now customers will not only receive the first DISA approved resilient timing and synchronization solution, they will also improve their Positioning, Navigation and Timing (PNT) cybersecurity with this additional layer of detection.

STL Precision Timing Option

Satellite Time and Location (STL) is a revolutionary new source for precision time based on the Iridium® constellation of satellites. With the reliance upon GPS and other GNSS signals becoming more and more common for critical applications, STL provides an ideal augmentation for these applications where "it just has to work." And with signal strengths approximately 1000x stronger, it can also provide high accuracy timing indoors where GPS and other GNSS signals can’t typically be reached.

Enterprise-Class SecureSync NTP Server

SecureSync® combines Spectracom’s precision GPS master clock technology and secure network-centric approach with a compact modular hardware design in a 1RU chassis to result in a powerful, scalable and flexible NTP appliance.

Supporting a wide variety of network synchronization and management protocols, the base model comes with a built-in 10/100 base-T Ethernet port for network management and high-performance NTP which can serve more than 7,500 NTP requests per second. It includes all the latest functions of NTPv4. It can be deployed in combination with other stratum-1 NTP server(s), can be used in a stratum-2 configuration, and can be expanded through option modules.

Options Modules Extend Synchronization Capability

A unique capability of SecureSync is to add hardware options at initial deployment or later as your network grows. An option adds three (3) 10/100/1000 interfaces to deliver NTP to multiple isolated LAN segments at 1 GigE. Two other options add PTPv2 functionality to the unit. One option is for a configurable master/slave PTP operation over a 10/100 network interface. The other is for PTP grandmaster functionality at 1 GigE. Up to six (6) of either types of ports can be added. Each PTP port is configured and operates independently to improve PTP performance since its processor is independent of all others in the system.

Along with precision 10 MHz and 1PPS outputs, all other physical synchronization signals can be generated as options so you can leverage your networking timing deployment to specifi c devices. Many of these signals can be used as references for redundancy or for other applications such as syncing across security boundaries via optical fiber.

Reliability and Scalability Supports All Timing Network Architectures

Several features support reliability and redundancy. SecureSync can also be deployed without the expense of a multi-GNSS receiver to operate as a Stratum-2 server. Units within the same stratum can be set as NTP peers. Any other timing source can also be a reference, such as T1/E1, time code, 1PPS, etc. You set the priority from all the available references. An internal oscillator maintains timing accuracy if all references are lost. Choose from TCXO, 2 types of OCXO and Rubidium. Add STL to GPS or GNSS to improve resilience, or use STL alone for indoor applications.

A Network-centric Approach

SecureSync is a security-hardened network appliance designed to meet rigorous network security standards and best practices. It ensures tamper-proof management and extensive logging. Robust network protocols are used to allow for easy but secure configuration. Features can be enabled or disabled based on your network policies. Installation is aided by DHCP (IPv4), AUTOCONF (IPv6) or SLAAC, and a front-panel keypad and display, and a command-line interface. A modern web browser user interface supports confi guration unit and an optional monitor of synchronization quality throughout the network.

NTP Over Anycast

Orolia NTP services, implemented in its SecureSync and NetClock 9400 platforms, are compatible with an Anycast routing scheme. The NTP over Anycast feature is a combination of the time server’s ability to associate one of its network ports to an Anycast IP address and to remove itself as an available time source if there is a problem with its reference.




SecureSync PTP Grandmaster

As methods of data transfer evolve, so too does the need for increased speed in information transmission.

Precision Time Protocol (PTP), as defined by the IEEE 1588 standard, provides the most advanced method of synchronization over Ethernet networks. Spectracom supports Precision Time Protocol Version 2 (PTP v2) in its SecureSync PTP Grandmaster Clock system. The standard configuration includes up to 6 PTP ports to operate various PTP deployments, allowing for maximum scalability to handle the expansion of your network infrastructure.
