Focus Telecom has introduced a new timing product for defense and mission-critical applications, the Time-Loader.
The Time-Loader can be deployed in environments where GNSS signals are denied or disrupted, to support any ground, naval and airborne system that needs real time of day (TOD) and 1PPS external synchronization aligned to UTC or GNSS.
In this emerging era of rapid tactical deployment of defense systems, communications intelligence, missile defense systems, radar/electro-optical sensors and UAS batteries in the field are often in GNSS-denied or jammed environments. This situation creates challenges for access to real time and accurate time of day.
To solve this problem, the Time-Loader generates a GPS L1 C/A code RF output as if the signal were coming from a live-sky GPS antenna. It provides full-constellation GPS output and is compatible with external GNSS receivers. It encodes times with nanosecond accuracy for GPS timing receivers.
The Time-Loader’s GPS-disciplined oscillator (GPSDO) is the Microsemi MAC-SA53/55, which provides excellent UTC accuracy with outstanding hold-over rubidium clock performance.
The Time-Loader is the size of a suitcase, hand-carried and easily deployed. It activates quickly from a cold start or when sensors are deployed for the first time.
Included in the Time-Loader is a self-contained, miniature GPS simulator that provides real-time extremely accurate signals. The 18-channel full-constellation simulator stores location/time/date data in internal memory and stores complex vector data to simulate dynamic scenarios. The simulator also can be used to transcode NMEA or SCPI position/velocity/time (PVT) data into GPS RF signals.
After a negotiation process that began in December 2021, Orolia officially joined Safran Electronics & Defense on July 8.
Orolia employs more than 435 people in Europe and North America and has revenues of about €100 million. Its solutions include atomic clocks, time servers, simulation and resilience equipment for GNSS signals, and emergency locator beacons for commercial aviation and military applications.
These products and solutions will complement Safran Electronics & Defense’s activities as it meets the challenges of positioning, navigation and timing (PNT) in contested and vulnerable environments, Safran said.
In most situations, GNSS receivers are the reference providers of time and position data. Still, they need to be secured by combining them with accurate, high-integrity autonomous time or inertial references.
Through this partnership with Orolia, Safran Electronics & Defense, will offer a comprehensive set of resilient PNT architectures and equipment to meet the challenges of integrity and robustness for the aviation, defense, space, transportation, new mobility and critical infrastructure markets.
“Orolia could not imagine a better fit than with Safran to secure its growth and leverage its PNT leadership positions,” said Jean-Yves Courtois, CEO of Orolia. “Thanks to the addition of best-in-class timing and inertial technologies, premier access to the largest defense and aerospace markets, and a proven track record in government program capture and execution, Safran and Orolia now have all the cards in hand to establish themselves as the resilient PNT leader.”
Martin Sion, CEO of Safran Electronics & Defense, said: “The acquisition of Orolia makes Safran one of the few companies with the full complement of PNT technologies, bringing together Orolia’s precise time referencing and Safran Electronics & Defense’s proven inertial navigation solutions. Our shared ambition is to become the world leader in resilient PNT for all conventional and strategic applications.”
Service providers harnessing the solution can now offer GNSS/GPS- backup-as-a-service (GBaaS) with enhanced precision and availability

ADVA has introduced its Oscilloquartz high-performance optical cesium atomic clock. The coreSync OSA 3300-HP is ADVA’s latest innovation in assured positioning, navigation and timing (PNT).
Following ADVA’s launch of an optical pumping timing solution two years ago, the OSA 3350 ePRC+, the OSA 3300-HP takes the technology to new levels. It has a 10-year lifetime compared to the five years offered by currently available high-performance magnetic clocks.
As a high-performance optical cesium clock, the OSA 3300-HP sets a new benchmark for precision and availability, ADVA claimed, providing the resilience required for PNT assurance in critical infrastructure and empowering service providers to deliver differentiated service-level-agreement timing offerings with integrated GNSS backup.
The feature-rich device has embedded Ethernet- and IP-based management as well as a user-friendly touchscreen graphical user interface.
“The launch of our coreSync OSA 3300-HP marks a key milestone in the design of atomic frequency and phase standards,” said Gil Biran, GM of Oscilloquartz, ADVA. “After many years of extensive work in our Swiss laboratories supported by the European Space Agency, we now have a mature, state-of-the-art technology that enables a major leap in the accuracy and stability of network timing while providing a substantially longer lifetime.”
Atomic clocks offer synchronization backup for networks that rely on GNSS-based timing, combining high accuracy with outstanding availability. The OSA 3300-HP commercial high-performance optical cesium atomic clock features an all-digital design and leverages optical-pumping techniques using laser diodes. This enables it to measure 100 times the number of atoms, making it more efficient compared to existing primary reference clock (PRC) technologies.
In 2020, OCP-TAP started working on highly precise and hyper-scalable time synchronization services in its data center market, using a GNSS clock source and precision time protocol (PTP) technologies. OCP-TAP technology adds scalability and improves the accuracy of timekeeping within the infrastructure industry.
In 2021, OCP-TAP integrated its technology into the time card and introduced it as an open-source solution to build time servers.
The Protempis Res720 embedded module provides a highly accurate GNSS clock source to further increase the accuracy, resiliency and adoption of the OCP-TAP’s new time card duo, which was announced in an OCP Tech Talk on June 2.
OCP-TAP provides a new collaborative community focused on designing hardware and software to efficiently support critical timing accuracy and resiliency demands on computer network infrastructure.
Protempis Res720
Protempis’s Res720 embedded module adds a dual-band GNSS time reference to the time card to improve resilience, noise rejection and anti-spoofing and anti-jamming capabilities.
The Res720 GNSS embedded timing module is suitable for data centers, 5G Open RAN and XHaul, smart grids, industrial automation and SATCOM networks. It provides 5 ns timing accuracy, dual-band GNSS support and anti-jamming/anti-spoofing capabilities.
The Res720 embedded module provides unparalleled performance as a timing source in embedded systems, including to time servers, network interface cards, radio units and routing/switching devices for 5G, private wireless, Open RAN and data networks.
“Protempis brings its expertise in GNSS and network synchronization to Meta, the OCP-TAP, and the open-sourced time card. Their highly accurate dual-band GNSS product has shown how it can improve operations,” said Ahmad Byagowi. Byagowi is inventor of the Time Card, founder and project lead for OCP-TAP, and a research scientist at Meta.
“We are honored that our Res720 dual-band technology will be used for enabling time-sensitive applications over OCP-compliant and PTP-aware networks,” said Karen Guldan, Protempis president. “We look forward to a continuing partnership with OCP-TAP and global network leaders working to advance solutions to provide ongoing timing accuracy and resilience.”
Precisional, an affiliate of The Jordan Company (“TJC”), announced May 9 that it completed the previously announced transaction to acquire four industrial technology businesses from Trimble, including Protempis (formerly Trimble Time and Frequency).
Thales and Syrlinks have signed a multi-year contract with the French defence procurement agency (DGA) to develop a new generation of tiny, high-performance atomic clocks.
Code-named Chronos, these new quantum clocks will meet the requirements of numerous civil and military applications. With their very high stability (error of less than 1 second in tens of thousands of years), defence electronics equipment will be able to operate when a GNSS signal is unavailable, for example due to hostile jamming.
Working with the procurement agency, the partners will help safeguard France’s technological sovereignty in GNSS-denied positioning, guidance, navigation and encrypted military communications. In civil applications (5G network synchronization, transport, energy, etc.), the Chronos quantum clocks will deliver low price and high performance to French and international customers.
Large swaths of the modern economy now rely on satellites for synchronization. GNSS technology provides the precise time reference for critical infrastructure such as 4G/5G networks, internet, air and rail transport, energy networks, global banking transactions and high-frequency trading, which would quickly fail if the signal were unavailable. In view of this high level of dependency, backup systems are needed to ensure that our civil and military infrastructure can continue to operate even if the GNSS timing signal is unavailable.
Thales’s industrial facility in Vélizy-Villacoublay and the Thales Research & Technology center in Palaiseau, both near Paris, have the industrial capabilities and talent to manufacture the atomic and optical core of these future quantum clocks.
Syrlinks — a French company based in Rennes, Brittany — specializes in satellite radiocommunications, radionavigation systems and miniature atomic clocks, and its products were selected to equip 650 satellites for the American operator OneWeb. The company will develop the electronic brain of the Chronos clock and guarantee its high-precision timing function.
The CNRS will provide critical scientific support for this project via its SYRTE (Observatoire de Paris) and Femto-ST (Université de Franche-Comté) joint research units.
An aviation industry coalition is voicing concern to Transport Canada about elements of a proposed mandate that will require aircraft flying in Canada to be equipped with the Automatic Dependent Surveillance-Broadcast (ADS-B), also called the Next Generation Air Transportation System, or NextGen.
ADS-B uses GNSS technology to calculate an airplane’s precise location, speed and direction. This information is transmitted twice per second, providing greater situational awareness for air traffic controllers.
The mandate in Canada requires aircraft to implement 1090ES ADS-B in two phases over the next four to five years. It takes effect for Class A and B Canadian airspace (above 12,500 feet) on Feb. 23, 2023, and Class C, D, and E airspace no earlier than 2026.
Space-Based Transceivers
The proposed mandate will also require antennas capable of communicating with both ground-based and space-based transceivers (referred to as antenna diversity). The United States uses ground-based ADS-B stations, which are confined to line-of-sight reception between the aircraft and ground receivers.
Space-based ADS-B does not have this limitation, but requires antennas on top of the aircraft to provide the required fidelity to allow for air traffic separation.
“This would constitute an equipage mandate for most U.S. operators wanting to fly to Canada, most of which have recently equipped to meet U.S. requirements,” said Jim McClay, director of airspace, air traffic and security for the Aircraft Owners and Pilots Association (AOPA). “To comply, many operators will need to install new antennas on top of their aircraft as well as possibly replace their ADS-B units. The costs of complying will be significant and would be borne only by aircraft owners.”
A recent AOPA survey of members in border states revealed that most U.S. operators are unaware of the coming mandate and almost half of respondents who regularly fly to Canada indicated they would cease flying to Canada altogether in the face of the mandate.
Lack of Installers
The industry coalition also agrees that it is highly doubtful that there are enough avionics installers to complete the needed upgrades in time to meet the mandate’s deadlines.
“Due to these concerns, AOPA is urging a delay of the Nav Canada equipage mandate until a determination can be made on the cost impact to purchase and install the required equipment and discussions on potential alternative solutions are held,” McClay said.
Other Countries
According to Nav Canada, the equipage requirements of Canada’s ADS-B mandate are in line with those of a growing number of other countries in the world. “The adoption of satellite-based surveillance technology ensures long-term alignment with the global aviation system,” the company stated. Nav Canada provides services to Canadian airspace such as air traffic control and weather advisories.
Members of the coalition include the Canadian Owners and Pilots Association, General Aviation Manufacturers Association, Garmin, the Canadian Business Aviation Association, AOPA and others.
Coalition members share concerns that the mandate being pursued by Nav Canada and Transport Canada does not appear to be going through the full consultative process, and will submit their concerns over the next several weeks.
Focus Telecom has installed its GPS Resilient Kit (GRK) cyber protection system in the national time systems of the State of Israel at the National Physics Laboratory in Jerusalem.
“A cyber protection system like the one installed in the National Laboratory, as well as many other systems we have developed to protect critical infrastructure, enable our customers to deal with the growing global threat and ensure the function of GPS-based systems, on which their business activity is based — even under jamming and spoofing attacks of various kinds,” said Shlomi Mazor, vice president of sales, Focus Telecom.
The company has developed a holistic model made up of several layers that can protect a GPS-based organization, according to the company.
Focus Telecom has been a leader in the field of synchronization and atomic clocks since 1995, and serves as Israel’s national timekeeper.
The company’s technology can detect an attack on an organization’s time sources, neutralize the threat of intrusion into the organization, provide alternative time from a secure highly accurate source, and protect internal organizational time distribution through a fiber-optic protection system through which time protocols are transmitted. It provides alerts for spoofing or jamming attacks as they happen.
Focus Telecom provides solutions in several layers, including secure NTP/PTP time servers, grandmaster atomic clocks, and radio frequency firewalls. These are protected by an active protection system that can detect and neutralize disruptions before they reach timing servers, and by additional technological solutions that provide effective protection against threats.
Focus Telecom cites recent jamming and spoofing incidents as highlighting the need for protection. For instance, pilots reported disruptions of GPS signals in June 2019, making it difficult to access Ben Gurion Airport. These disruptions resumed in January 2022 and pose a renewed challenge to pilots.
In a May 2021 incident, farmers on the northern border and in the Gaza Envelope reported disruptions affecting the GPS-based guidance system installed in tractors used for sowing and harvesting.
Focus Telecom’s systems are successfully integrated into the Israel Defense Forces, defense industries, financial institutions, communications companies, and Israel’s transportation, electricity and water infrastructure.

ADVA is enabling service providers to offer GPS/GNSS-backup-as-a-service (GBaaS) to answer the need for operators to safeguard services that rely on positioning, navigation and timing (PNT) information.
Along with spoofing and jamming of GNSS, in-network timing based on network time protocols (NTP) and precision time protocols (PTP) are also increasingly vulnerable to cyber threats.
As a response, ADVA is now empowering service providers to offer GBaaS and enable end users to address new guidelines and standards for redundant PNT architectures. GBaaS meets the latest recommendations for PNT homeland security, including U.S Executive Order 13905. Leveraging ADVA’s aPNT+ technology, GBaaS eliminates the risks and costs associated with GNSS dependence.
“Threats to hamper PNT capabilities are growing, and much of the world’s critical infrastructure is still without adequate protection from GNSS vulnerabilities,” said Gil Biran, general manager of Oscilloquartz, ADVA. “All of that can change when service providers are able to offer GBaaS.”
GBaas is based on ADVA’s aPNT+ platform, which leverages a suite of technologies, including multi-band GNSS receivers and management software based on artificial intelligence and machine-learning.
Service providers can offer ADVA’s aPNT+ protection as a subscription-based service as part of their service-level agreements.
ADVA’s GBaaS solution employs a combination of multi-layer detection, multi-source backup and fault-tolerant mitigation to render timing networks more secure. Embedded in all timing devices, ADVA’s Syncjack technology provides comprehensive and precise synchronization performance monitoring and analytics, enabling the Ensemble Sync Director network management suite to intelligently operate and prioritize multi-source timing feeds across the network.
Onboard multi-band GNSS receivers boost timing accuracy and also protect against attacks like jamming and spoofing. When GNSS is either unavailable or compromised, a dispersed network of autonomous cesium atomic clocks and network backup timing feeds is ready to deliver highly accurate network timing over long periods of GNSS unavailability.
The PTSS is designed to give nations, institutions, critical infrastructure operators and scientific labs control over the time source for their critical infrastructure systems. It provides a high-quality back-up or alternative to GNSS as a source of time, which can be distributed through eLoran, IEEE 1588 over fiber, two-way time transfer, and other methods.
Core products integrated into the PTSS:
SyncSystem 4380A Time Scale Edition generates an autonomous time scale derived from combining several highly accurate independent clocks with a multi-channel instrument for measuring and comparing clock performance.
Time Scale Orchestrator is a software platform providing a unified view with a built-in database that integrates the management, monitoring, alarming and reporting functions of the individual products that form the time scale system.
5071A Cesium Clock Primary Frequency Standard and MHM 2020 Active Hydrogen Maser are Microchip’s atomic clocks that provide accurate and stable frequencies continuously measured against each other to compute and generate the ensemble time-scale frequency.
The PTSS integrates the new portfolio of time scale products into a turnkey solution, available in a single rack and guaranteed by a complete factory acceptance test (FAT) that exceeds the most stringent requirements.
Leveraging Orolia’s HATI core in combination with Arista MetaWatch, the integration provides sub-nanosecond timestamping with accurate, precise and reliable timing
The collaboration between Orolia and Arista sets a new standard in time synchronization for FPGA-based network devices with the support of native White Rabbit capabilities to achieve sub-nanosecond time synchronization using optical fibers across multiple points in the network.
This integration is factory-supported in combination with the MetaWatch application in the Arista 7130LB platform, enabling distributed traffic capture with high-resolution timestamping, buffering and de-duplication, to provide advanced network monitoring and detailed network analytics. Deep buffering, time-ordered aggregation and de-duplication reduce the load on downstream packet capture and analysis devices.
“One key feature of this important collaboration is the simplification of the overall network architecture by eliminating coaxial cabling and PPS distribution equipment,” said Francisco Girela, White Rabbit application engineer with Orolia. “This integrated solution eases the adoption of White Rabbit, leading to cost savings, reduced footprint and better scalability.”
White Rabbit is an ultra-accurate IEEE 1588 Precision Time Protocol (PTP) implementation that achieves sub-nanosecond accuracy over optical fiber links. Designed for use in avionics, telecommunications, space, defense and scientific applications, White Rabbit has become the gold standard for time distribution within electronic trading networks.
Arista’s MetaWatch is a powerful FPGA-based network application designed for Arista’s 7130 platform and combines several components of a traditional network monitoring solution into one device, which simplifies network data capture, monitoring and analytics.
“Moving from analog time synchronization to fiber-based White Rabbit will allow our customers to improve their network analytics while improving the overall synchronization accuracy across a large estate,” said David Snowdon, engineering director, Arista. “The combination of MetaWatch and White Rabbit allows for less than a nanosecond of error on any timestamp taken in a wide-area network — a crucial feature for trading firms optimizing their latency, or for exchanges guaranteeing fairness.”

Orolia’s WR Z16, a reliable and precise time fan-out solution for White Rabbit distribution on 1G Ethernet-based networks, is a standalone device with 16 SFP connectors that provide sub-nanosecond accuracy over the plug-and-play optical fiber links. The HATI core requires an activation license generated by Orolia to be loaded in the reference WR-Z16 device paired with it to be functional.
Xona has completed environmental testing for its upcoming demo mission, a significant step towards realizing its high-performance commercial navigation system
Xona Space Systems announced that their first in-space demonstrator has been delivered to Spaceflight Inc. for final integration after successfully completing testing and is scheduled for launch on SpaceX’s Transporter 5 in May.
Xona is an aerospace startup developing a precision navigation and timing system in low Earth orbit. It plans to build an independent high-performance satellite navigation and timing system to meet the needs of intelligent systems.

Satellite navigation systems such as GPS and Galileo are in the domain of major governments (and free to users). Xona said it is part of the new commercialized space movement, using it to bring benefits to satellite navigation and timing.
Xona Space is launching Huginn, the first of two missions, demonstrating the capability of its Pulsar constellation. Pulsar’s architecture uses small, powerful satellites in low Earth orbit, more than 20 times closer to Earth than GPS satellites, which are in medium Earth orbit.
Pulsar is planned to deliver high-performance navigation and timing services by combining security and signal designs with Xona’s patent-pending distributed atomic-clock architecture to enable robust precision navigation services from low-cost satellites. Its precision LEO positioning, navigation and timing (PNT) service leverages advances in small satellite technology to provide users with a secure and robust alternative to traditional GNSS.
Xona’s system architecture utilizes the efficiency of small satellites to provide an affordable global system with more than 10 times better accuracy and 100 times better interference mitigation than legacy systems, the company claimed
Huginn will transmit the first precision navigation signals from a LEO spacecraft, designed to test and validate the core software and hardware technology that Xona has developed for Pulsar. The mission will also demonstrate the functionality of end-user equipment on Earth and supporting ground systems.
Huginn is now going through final integration with Spaceflight in preparation for launch on the scheduled Transporter 5 mission in May.
“We’re thrilled that Huginn has successfully completed its very rigorous test campaign in preparation for launch and are incredibly proud of the Xona team for achieving such a critical milestone,” said Brian Manning, CEO of Xona. “Through this process, we learned a massive amount and will be incorporating these lessons into our second demo mission as well as the production satellites.”
Following the Launch of Huginn, the Xona team will shift focus to the second demonstration mission as well as the development of the Block I Pulsar system.
The final Pulsar constellation will consist of several hundred LEO satellites, delivering secure and robust precision PNT services designed to meet the needs of advanced applications such as self-driving cars, precision agriculture and construction, augmented reality, critical infrastructure, and many others.
“It is inspiring to see what this team has been able to achieve going from a blank slate to orbit in less than a year from the time we completed our ground-based prototype testing,” Manning said. “This is a huge step in the development and deployment of our Pulsar constellation, and we’re looking forward to a very exciting year here at Xona.”
Xona is backed by Seraphim Space Investment Trust (LSE:SSIT) and MaC Venture Capital, with participation from Toyota Ventures, Daniel Ammann (co-founder of u-blox), and Ryan Johnson (former CEO of BlackBridge, operator of the Rapideye constellation). Follow-on investors also include 1517 Fund and Stellar Solutions.

Microchip Technology Inc. has announced its GridTime 3000 GNSS time server, a software-configurable solution providing power plants and substations with a new level of redundancy, security and resiliency to protect against surges, adverse weather and cyberattacks targeting critical infrastructure.
Meeting the Need
Power plants and substations rely on high-speed communications networks to transmit critical data including operability metrics, network health, fault monitoring, power measurement and usage trends. To synchronize communications and ensure continuity across these networks, substations require secure, precise timing and synchronization to avoid false tripping and to provide accurate time-stamping of substation data including system faults, power-measurement data and substation status information.
The launch of the Microchip GridTime 3000 GNSS Time Server assists power-grid operators to meet these requirements.
The GridTime 3000 system generates precise time and frequency signals to synchronize analog and digital communication systems. This resilient timing platform incorporates multiple timing inputs for protection in the event of a GNSS signal disruption caused by severe weather, environmental disturbances or signal jamming or spoofing.
