INS
Combines a GPS master clock with an INS

The Geo-APNT serves applications requiring precise navigation data and an accurate time reference. The Geo-APNT combines a versatile GPS master clock with an INS to
offer assured positioning, navigation and timing (PNT) under all circumstances, including temporary loss of GPS signal. It minimizes size, weight and power (SWaP) due to the integration of positioning and timing that are typically achieved by two independent subsystems.

It can be easily integrated into existing systems and supports RTK and PPK positioning and offers support for MEMS, fiber optic gyro and ring laser gyro inertial measurement units (IMUs). The system also includes GPS antenna and cables.

Adtran has released two optical cesium atomic clocks, the OSA 3300 Super High-Performance (OSA 3300 SHP) and the OSA 3350 Super Enhanced Primary Reference Clock+ (OSA 3350 SePRC+). The devices use optical pumping technology to meet evolving demands across applications from scientific research to critical positioning, navigation and timing (PNT) infrastructure.

The OSA 3300 SHP offers stability and accuracy, making it a valuable tool for metrology institutes and scientific research facilities. The OSA 3350 SePRC+ is specifically designed to enhance holdover capabilities for PNT services. It maintains 100 days of 100-nanosecond precision, providing continuous and accurate timing even in environments where GNSS is compromised or unavailable. This makes it a crucial component for ensuring the integrity of mission-critical networks and supporting vital infrastructure and defense operations with reliable backup timing.

“In an era marked by rising global tensions and heightened risks of state-sponsored interference in satellite communications, our latest innovation has arrived at a pivotal moment. It will greatly enhance our capacity to address the demand for secure and reliable network timing around the world,” said Gil Biran, GM of Oscilloquartz, Adtran.

A leading Canadian hydropower producer is using the Adtran Oscilloquartz grandmaster device combined with its optical cesium atomic clock to achieve new levels of precision, reliability and resilience in its power grid synchronization network.

The deployment addresses the urgent need to implement the highest standards of protection against GNSS disruptions — including jamming and spoofing cyberattacks — and helps bolster North America’s energy resilience. Featuring multi-source protection, the enhanced timing architecture offers a zero-trust approach to positioning, navigation and timing (PNT), ensuring robust and accurate synchronization. It also seamlessly supports existing services, which allows for a smooth transition from legacy timing to power grids with advanced PTP technology. For streamlined operations and assurance, the synchronization network is remotely managed through the Adtran Ensemble Controller with Sync Director.

By enhancing its timing framework with Adtran’s Oscilloquartz solution, the hydroelectric producer is designed to maintain the highest standards of cybersecurity and energy reliability in its critical infrastructure, the company said. The deployment aims to improve the stability and security of the energy supply across Canada and the United States.

The new solution includes Adtran’s OSA 3350 ePRC+ combined with the OSA 5422 to provide precision, stability and resilience against GNSS vulnerabilities. It has an all-digital design, which utilizes optical-pumping techniques, to guarantee timing accuracy and optimal stability for over a decade. This is twice the lifespan of conventional cesium clocks.

With the OSA 5422, the solution future-proofs the utility’s timing network and assures compliance with governmental regulations. It fortifies security and underscores the renewable energy utility’s commitment to maintaining a continuous, secure power supply.

Iridium Communications has entered a five-year agreement with L3 Harris. Under the agreement, Iridium will provide its satellite time and location (STL) service to more than three dozen L3Harris-operated communications network backbone nodes and a similar number of Federal Aviation Administration (FAA) facilities throughout the United States.

L3Harris, responsible for operating a private network for the FAA, provides voice, data and video communications for the National Airspace System operations and mission support functions. Given the critical nature of timing synchronization within the L3Harris communications network, particularly for supporting various critical infrastructure applications, the Iridium STL service plays a pivotal role in the overall network timing architecture by eliminating dependencies on GPS as the primary timing source.

The solution for L3Harris includes compact devices provided by Adtran’s Oscilloquartz division, which are designed to receive Iridium STL signals. These devices seamlessly integrate into the network and meet nationwide network timing synchronization requirements.

In April 2024, Iridium acquired Satelles, a secure satellite-based time and location service provider.

Sweden’s leading position in digital services and telecommunications highlights the need for robust timing services, which are fundamental to the functioning and security of digital infrastructures. The introduction of coreSync OSA 3300-HP by Netnod — a company specializing in providing internet exchange, DNS, and time services in the Nordic countries — aims to enhance the accuracy, stability and durability of timing synchronization services across the country.

By deploying Oscilloquartz super ePRC technology across six pivotal timing centers nationwide, Netnod aims to address the growing concern over GNSS vulnerabilities. The optically pumped cesium technology of the coreSync OSA 3300-HP offers a highly stable and precise alternative timing source, providing frequency stability and an operational lifespan double that of traditional magnetic cesium clocks.

Vodafone Turkey has integrated Adtran’s Oscilloquartz optical cesium atomic clock technology into its national network. The integration aims to enhance the resilience of network synchronization against disruptions in GNSS signals, a crucial step as the company progresses towards the implementation of 5G services.

The deployment establishes a network-wide synchronization solution capable of maintaining precise timing, even during GNSS outages. This technology is essential for ensuring continuous, reliable connectivity across Vodafone Turkey’s services.

The core of the solution, the Oscilloquartz OSA 3350 ePRC+, uses optical pumping technology for frequency stability. This device, combined with Vodafone Turkey’s existing grandmaster clocks and the Oscilloquartz clock combiner, forms the ePRTC+ system.

The system is designed to achieve a 100-nanosecond accuracy level for a period extending to 45 days, which surpasses the ITU-T G.811.1 standards for network timing.

Vodafone Turkey will implement a system across five strategic sites to mitigate risks associated with GNSS signal loss that can impact network operations and service quality. This aims to enhance redundancy and ensure network stability under challenging conditions including natural disasters and electronic interference.
