“We are honored to have this opportunity to collaborate with Meta’s incredibly talented team of engineers to develop a unique open-source solution using our mRO-50 technology,” said Jean-Yves Courtois, Orolia CEO. “We look forward to a continuing partnership with Meta and other global network leaders working to advance solutions to ensure ongoing timing accuracy and resilience.”
Orolia developed the ART Card solution in collaboration with the Meta engineering team to fulfill a new specification that Meta published for the Time Appliances Project Initiative of the Open Compute Project. This new collaborative community is focused on designing from scratch new hardware and software to efficiently support the critical timing accuracy and resilience demands on computer network infrastructure. This project is fully open-sourced and available on Orolia’s GitHub.
In 2020, Meta began converting its data-center servers to a new time-distribution service based on network time protocol (NTP) and precision time protocol (PTP). The new service, built in-house and later open-sourced, was more scalable and improved the accuracy of timekeeping within the Meta infrastructure from 10 milliseconds to 100 microseconds. Orolia ART Cards will further increase the accuracy, resiliency and adoption of Meta’s new timing platform.
Developed with long-term support in mind, Orolia’s ART Cards deliver management, disciplining and monitoring functions that can be integrated into any computer with a PCIe port and bring accurate and resilient timing for the most demanding applications such as NTP/PTP time reference, time stamping and latency calculation.

The International Maritime Organization (IMO) has issued a resolution for maritime cyber-risk management, effective January 2021. IMO Resolution MSC.428(98) affirms that maritime operators need to address cyber threats that risk the integrity and availability of technology systems.
GPS/GNSS signal jamming and spoofing expose the vulnerabilities of PNT-reliant systems. The single point of failure in the signals used to synchronize military operations or determine a vessel’s location leaves maritime systems open to attack. With resilient PNT, maritime and naval vessels can rely on trusted data.
Remote Operations at Sea. In September, Orolia participated in a Remotely Operated Service at Sea (ROSS) demonstration where an unmanned vessel was tele-operated from more than 800 kilometers (500 miles) away.
With its SecureSync Interference Detection and Mitigation (IDM) suite, Orolia provided the project’s PNT cybersecurity package and delivered precise, reliable data for the control center to pilot the vessel from afar. The IDM suite includes GNSS threat detection and mitigation, as well as the option to include encrypted and alternative signals for use in GNSS-denied environments.
After this successful demonstration, SeaOwl Group, the company leading the ROSS project, obtained the first remotely operated vessel navigation license in France.
Diving Deep. Atomic clocks and oscillators are useful for underwater operations where RF signals are unavailable to provide accurate PNT data. Precision timing technologies, such as Orolia’s Spectratime mRO-50 oscillator, ensure stable timing for navigation systems through radar. They support missions such as:
stabilizing and synchronizing sensor measurement data collection for autonomous underwater vehicles (AUVs)
providing holdover to maintain precise positioning on submarines during extended periods of GNSS signal denial
generating precise frequencies with low phase noise and less burden on radio receiver architecture, such as search-and-rescue control centers
operating with low power consumption and increasing the reliability of radio reception.
Resilient PNT is essential at sea, from military missions and commercial freight shipping to port management, search and rescue, research and fishing operations. Jamming and spoofing detection, threat mitigation, and alternative PNT sources configured in multiple layers of protection can ensure continuous operations, even in compromised environments. In shallow or deep-water environments, Orolia’s portfolio includes critical infrastructure support for naval command-and-control centers, essential GNSS vulnerability testing and services, and wearable solutions that fit in the palm of a hand.

Orolia has introduced a low SWaP-C miniaturized rubidium oscillator, the Spectratime mRO-50, designed to meet the latest commercial, military and aerospace requirements where time stability and power consumption are critical. The oscillator is low SWaP-C — size, weight, power and cost.
The Spectratime mRO-50 provides a one-day holdover below 1 µs and a retrace below 1 x 10-10 in a form factor sized 50.8 x 50.8 x 19.5 millimeters. It takes up only 51 cc of volume — about one-third of volume compared to standard rubidiums — and consumes only 0.45 W of power.
he Spectratime mRO-50 miniaturized rubidium oscillator provides accurate frequency and precise time synchronization to mobile applications, such as military radio-pack systems in GNSS-denied environments. Its operating temperature of -10°C to 60°C (military version extends to -40°C to 75°C) is also suitable for UAVs and underwater applications.
Orolia is a leader in space-based atomic clocks and high-end crystal, rubidium, hydrogen maser and integrated GPS/GNSS clocks. The company also provides testing instruments for space missions that rely on high precision atomic clock technology.
Orolia’s Atomic Clocks team received the 2019 PTTI Distinguished Service Award in January for advancing the state of the art in high-stability atomic clocks and producing the only space-based passive H-maser in the world, operating on all Galileo satellites. Spectratime mRO-50 is the latest technology solution from this award-winning team.
“Through Orolia’s continuous commitment to innovation, we are proud to offer our customers more precise PNT data in a cutting-edge, lightweight form factor for mobile missions,” said Orolia’s Atomic Clocks Product Line Director, Jean-Charles Chen.
