Exail has unveiled the Advans Vega SL, a new high-precision inertial navigation system that maintains navigation continuity across amphibious operations.
In contested littoral environments, maintaining reliable navigation across the sea-to-land transition remains a persistent challenge for amphibious forces. In the event of GNSS jamming, spoofing or signal unavailability, the Advans Vega SL operates independently of any external signal from vessel departure to shore, ensuring forces maintain continuous positioning and fire control readiness without reconfiguration at any stage.

As a single, self-contained solution covering both maritime and land phases, it also removes the integration constraints associated with multi-system architectures, which typically require reconfiguration or handover at the water-to-land transition.
With 0.05° RMS heading accuracy in the maritime phase and 0.5 mils RMS on land, the Advans Vega SL system maintains positioning continuity in GNSS-denied environments without reconfiguration.
“GNSS signal denial is now an operational assumption in any amphibious and littoral combat planning,” said Yann Le Balc’h, business development manager for land defense, Exail. “The Advans Vega SL removes satellite dependency at the most exposed phase of an amphibious operation, giving forces the autonomy to project ashore on their own terms.”
Drawing on Exail’s fiber-optic gyroscope technology, the Advans Vega SL delivers 0.05° RMS heading accuracy in the maritime phase and 0.5 mils RMS on land — the highest navigation precision achieved to date in a system designed for the full sea-to-land transition. This performance level is rooted in decades of navigation expertise across land and naval operations, now brought to bear on a capability requirement that has become increasingly critical in modern amphibious warfare.
With navigation systems in service with more than 70 navies and land forces worldwide, Exail is a recognized supplier for defense forces requiring sovereign, signal-independent positioning capability across all operational domains.
CHC Navigation (CHCNAV) has released the AlphaAir 6, a flagship airborne lidar system designed for UAV-based laser scanning, drone lidar mapping, and aerial surveying in high-relief and complex terrain.
Combining prism scanning technology with a high-grade inertial navigation system (INS), the AlphaAir 6 delivers a maximum ranging capability of up to 2,100 meters and supports efficient data capture at typical flight altitudes of 400 to 600 meters above ground level.
The AlphaAir 6 integrates an upgraded laser engine and a high-grade IMU with 0.3°/h bias stability to improve trajectory accuracy and point cloud quality. This design removes the need for pre-mission IMU calibration and supports stable, efficient data collection for topographic mapping, corridor mapping, and wide-area aerial survey workflows.
The AlphaAir 6 combines fifth-generation real-time waveform processing with advanced multi-period technology to capture richer, denser, and more precise lidar data across complex terrain, vegetation, and built environments. According to CHCNAV, even at an ultra-high pulse repetition rate of 2,000,000 pulses per second, it continues to support real-time point cloud output, giving operators immediate in-flight visibility and a faster path to survey-grade 3D results.
To meet different project requirements, the AlphaAir 6 is available in single-camera and dual-camera configurations. Both options use large-format CMOS sensors to deliver high-resolution imagery, while the dual-camera version adds an ultra-wide field of view to improve image coverage and increase mapping efficiency.
With an integrated design and a weight of 1.35 kg, the AlphaAir 6 reduces payload burden on UAV platforms and helps extend flight endurance. Open interface protocols support integration with mainstream multirotor and fixed-wing UAVs, giving surveying and mapping professionals more flexibility across different mission types.

Inertial Labs, a Viavi Solutions Inc. company, has announced IRINS, a low Earth orbit (LEO)-aided inertial navigation system (INS) designed to allow full operation across land, air and sea in GNSS-denied, -degraded and -disrupted space operating environment .
Combining the capabilities of an INS, an altitude and heading reference system (AHRS) and a LEO PNT receiver, this platform marks a major milestone in Viavi’s portfolio for assured positioning, navigation and timing by bringing together the INS capabilities of inertial labs and the timing expertise of Jackson Labs.
The IRINS embedded system has been developed to counter the exponentially rising number of spoofing and jamming attacks that have affected military and critical infrastructure. Now, resilient LEO-based PNT and inertial navigation are available within a fully integrated system from a single vendor.
The system combines an INS, an AHRS and the GNSS-independent STL-2600 LEO Iridium receiver module. These capabilities enable the system to calculate altitude, position, velocity and time data, as well as minimize bias from causing drift. To help detect and eliminate attack signals, the device additionally integrates a GNSS receiver with a controlled reception pattern antenna (CRPA) port.
“The IRINS is the first fruit borne of VIAVI’s visionary strategy to mitigate vulnerabilities in positioning, navigation and timing, bringing together resilient satellite-based timing with tactical-grade IMUs to deliver the most precise PNT for GNSS-denied environments,” said Jamie Marraccini, vice president, Inertial Labs Products, Viavi. “By tightly coupling inertial sensing, LEO-based timing and navigation and anti-jam GNSS technologies into a single platform, the IRINS provides unmatched continuity, accuracy and trust for operations in contested and denied environments.”
“Assured access to PNT is critical for operations in contested environments,” said Maynard Porter, Director, Government PNT Business, Iridium. “Integrating Iridium PNT alongside VIAVI’s INS and AHRS provides users with an exceptionally resilient source of time and location data to maintain operational effectiveness when GNSS signals are disrupted.”
The IRINS is certified for IP67 and MIL-STD-810G environmental requirements. It is based on the company’s fully calibrated tactical-grade MEMS 3-axis accelerometer, gyroscope and clock. These are combined with embedded barometers, magnetometers and an optional onboard air-data computer as part of its AHRS.
Satellite communication is provided through the company’s STL-2600 receiver, which links to the Iridium LEO constellation. All capabilities are housed within a compact 126.5 × 49.3 × 53.3 mm enclosure.
Anello Photonics has launched the Anello Aerial inertial navigation system (INS), a compact, high-performance inertial navigation system built around the company’s Silicon Photonics Optical Gyroscope technology and integrated with multi-band GNSS receivers.
Anello made the announcement at CES 2026, taking place this week in Las Vegas.
The Anello Aerial INS is built for demanding aerial platforms — including BVLOS UAS, maritime/shipborne VTOL UAS, ISR/special-mission aircraft, heavy-lift and cargo drones, and other autonomous aerial vehicles. The system is powered by an advanced EKF-based sensor fusion engine and ANELLO flight-profile-tuned algorithms, consistently delivering >98% navigation accuracy without the need for cameras or fiber-optic cables.
The Anello Aerial INS delivers <0.5 deg/hr unaided heading drift, maintaining accurate navigation and control through high-dynamics and GNSS jamming, spoofing, or occlusion. Anello’s navigation solutions are built to deliver assured performance in fully GNSS-denied environments — whether operating over water or desert corridors, in night or low-light missions, or through fog and cloud cover — maintaining precise guidance without GPS and enhancing warfighters’ effectiveness and survivability.
“Customers flying real missions need resilient navigation when GPS isn’t reliable,” said Mario Paniccia, co-founder and CEO of Anello Photonics. “By combining our SiPhOGs with our airborne-optimized sensor-fusion algorithms and integrated multi-band GNSS, the Anello Aerial INS delivers accurate navigation solutions in a cost-effective SWaP-friendly package. This allows UAVs to hold course through GPS jamming, multipath, spoofing, or outages using only Anello without the need for cameras or fiber-optic cables and allows the warfighter to complete their mission safely and successfully.”
ANELLO’s full product portfolio has been developed in close collaboration with customers and verified through comprehensive integration and mission-platform testing.
The Anello Aerial INS is available for evaluation today with production shipments beginning in the second quarter of this year. Evaluation kits include the Anello Aerial INS, cabling, drivers for PX4/ArduPilot, and a quick-start integration guide.
CPI Electron Device Business – TMD Technologies Division has successfully completed sea trials of its cquantum-hybrid inertial navigation system (INS) aboard the THV Galatea, operated by Trinity House, the General Lighthouse Authority for England, Wales, the Channel Islands and Gibraltar.
This milestone shows that quantum-enabled sensing hardware can operate stably in maritime conditions, with the potential to provide resilient positioning without continuous reliance on GNSS.
Research indicates that a 24-hour GNSS outage could cost the UK economy £1.4 billion through cascading effects on logistics, transportation and critical infrastructure, underscoring the need for GNSS-independent solutions. By proving that quantum sensors can operate in operational conditions aboard a working vessel, CPI TMD is advancing technologies that reduce reliance on satellite navigation and improve resilience across maritime, defense and commercial sectors.
The Harlequin System: Quantum-Enhanced INS
The Harlequin system is a quantum-classical hybrid INS designed to extend GNSS holdover — the ability to maintain accurate position when satellite signals are unavailable or unreliable. Developed under an Innovate UK funded project, with partners from industry and academia, including the University of Strathclyde, and Joseph Cotter’s group at Imperial College London, Harlequin integrates classic INS components (a precise clock, a ring laser gyroscope, and a MEMS accelerometer) with CPI TMD’s gMOT-based quantum accelerometer.

The gMOT cold atom source, developed by CPI TMD, the University of Strathclyde and Kelvin Nanotechnology, is a grating-based magneto-optical trap that provides a source of ultra-cold atoms that forms the basis of a portable, rugged quantum sensor.
Conventional INS technology accumulates errors over time, causing position estimates to drift. By integrating its cold-atom accelerometer technology with classical INS technology, Harlequin leverages quantum-enhanced sensing to perform periodic drift corrections, extending the period over which a vessel can maintain accurate position in the absence of satellite-derived timing and positioning.
Real-world trials: Operating around a working vessel
The Harlequin trial demonstrates that quantum sensors can operate reliably outside the lab, functioning in the harsh conditions of real-world maritime operations—a crucial validation step toward field-deployable systems.
The sea trial took place aboard the THV Galatea, which is not a scientific test vessel but an operational ship with a demanding day job: keeping shipping routes safe by ensuring buoys and lights are correctly placed and maintained, surveying the seabed for hazards, marking wrecks, and supporting marine-infrastructure projects such as cables and pipelines.
The Harlequin system had to be loaded, tested and unloaded around the Galatea’s regular operational schedule, adding complexity to the trial and underscoring the system’s ability to integrate into real-world maritime workflows.
Next Steps: System Upgrades and Second Trial
Data gathered during the trial will inform a program of system upgrades aimed at improving performance and enhancing suitability for long-term shipboard operation. A second field trial is planned for the end of 2026 to validate improvements and bring it closer to operational readiness.
Advanced Navigation has finalized a multi-million deal with Kongsberg Defence & Aerospace to supply more than 50 Boreas D90 fiber-optic gyroscope inertial navigation systems (FOG INS) to strengthen Kongsberg’s Protector RS4 in high-threat, contested environments.
As a strategic-grade INS, the Boreas D90 is engineered for the world’s most extreme environments, maintaining exact targeting and unwavering line-of-sight control for the Protector RS4.
The Boreas D90 was selected not only for its superior precision in GNSS-denied conditions, but also for Advanced Navigation’s proven capacity to meet demanding delivery timelines. This agility is made possible by the company’s state-of-the-art, vertically integrated manufacturing. By controlling the entire production process, from sourcing raw components to assembly and testing in simulated EW environments, Advanced Navigation can rapidly scale output on demand and guarantee schedule certainty, a critical factor for Kongsberg.

The Protector RS4 is the world’s most fielded remote weapon system, deployed across more than 30 nations and multiple domains. The highly flexible, modular system is designed to integrate a diverse range of payloads, including small and medium caliber systems and guided effectors. Its advanced, modular sensor suite (day, night, LRF) provides exceptional and customizable situational awareness.
The fully stabilized 2 + 2 axis (detached line of sight) system allows the operator to maintain focus on a point of interest, independent of platform movement or the delivery solution for the specific system in use. The Protector RS4 is platform-independent and suitable for both land and sea applications.
By integrating Boreas D90, the Protector RS4 achieves a new level of precision and survivability, sustaining locked targeting and georeferenced stability even when GNSS is compromised or denied. This enhancement positions Kongsberg’s Protector RS4 as one of the few systems globally capable of maintaining precision pointing under active electronic warfare attack.
The deal supports the Global Supply Chain (GSC) Program, an initiative by the Australian Department of Defence designed to connect local suppliers with major global defense prime contractors. Advanced Navigation is based in Australia; Kongsberg is based in Norway.
Nortek’s DVL 333 Surface, designed specifically for uncrewed surface vessels (USVs), enables USVs to maintain position or navigate when GNSS is lost.
Uncrewed surface vessels (USVs), often called sea drones, help monitor, map and secure the world’s oceans, performing tasks and surveys for less expense and risk than traditional crewed vessels. USVs are used in environmental monitoring, offshore inspection, subsea infrastructure protection, and defense missions such as intelligence, surveillance and reconnaissance (ISR).
USVs require reliable navigation and positioning information, particularly when performing autonomous operations. This information typically comes from GNSS.
But during GNSS outages, USV operators are turning to alternative sensors for positioning. Without GNSS, a sole inertial navigation system (INS) on a vessel quickly drifts outside of acceptable levels when performing dead-reckoning navigation. By adding a Doppler Velocity Log (DVL) to the USV, operators can perform long-distance, dead-reckoning-based positioning with much lower drift.

In subsea navigation systems, DVLs provide vehicle velocity information using acoustic returns from the seabed. Because DVLs offer an accurate velocity estimate with no drift, combining a DVL with an INS constrains the drift that would accumulate with an INS alone. Using a DVL allows USVs to maintain position or even navigate without requiring GNSS information, enabling fully autonomous navigation independent of potentially vulnerable signals.
However, deploying DVLs on surface vessels introduces its own set of engineering and operational challenges. Conventional DVLs typically feature protruding transducer heads that are not flush with a vessel’s hull — challenging on smaller or high-speed vessels.

The compact Nortek DVL 333 Surface is designed for flush-hull installation, minimizing drag and protrusion below the hull line. It features a concave, fluid-filled transducer cavity sealed with an acoustic window, allowing for full control of sound velocity and eliminating the need for a hull-mounted speed-of-sound sensor.
When paired with a high-grade INS, the DVL 333 Surface delivers accurate position updates even during GNSS outages or interference. Its 300-meter bottom-track range supports fully autonomous operation in coastal waters, while a water-track mode extends functionality in deeper environments where the bottom is out of range. The DVL333 Surface can also be upgraded to Nortek’s VM Operations vessel-mounted ADCP system. For ease of maintenance, an optional type-certified sea valve allows in-water servicing without dry-docking.
Validating capabilities in the field
The capabilities of the DVL 333 Surface were demonstrated during field trials in the Oslofjord, an inlet in Norway. The test site presented conditions representative of complex coastal environments, where depth can vary significantly over short distances, and the seabed composition ranges from soft sediment to rock. Unlike uniform test sites with flat, sandy bottoms, the Oslofjord provides a realistic proving ground for challenging navigation scenarios.
“Our goal was to demonstrate that a surface vessel can maintain precise positional accuracy even during a complete GNSS blackout, and to do so in truly challenging coastal conditions,” said Torstein Pedersen, Nortek.

The navigation tests were carried out using a DVL 333 Surface integrated with an Exail PHINS 6000 INS. Although the trial track was relatively short, the system’s performance quickly stabilized, achieving a stable, long-term accuracy of approximately 0.05% of distance traveled (for instance, 50 cm error each 1 km traveled). When bottom track was disabled (simulating operation outside of the DVL 333 Surface’s 300 m bottom track range) and only water track was used with the PHINS INS, the horizontal position error remained within 8 meters over a three-hour run, with the DVL operating solely in water-track mode. In this mode, the INS estimates background currents, which were accurately estimated as weak, stationary currents.
“We were particularly impressed with the performance of the system when using just water track mode,” Pedersen said. “The Exail INS was able to use the water track information to estimate currents and correct for them in the navigation, which is not an easy task to do with accuracy over extended periods. This performance is critical for open water navigation.”
These results confirm that the DVL 333 Surface delivers reliable navigation performance in variable bottom conditions and without a direct speed-of-sound measurement. More importantly, they demonstrate the availability of a commercially available DVL that overcomes the challenges typically faced when adapting subsurface systems for surface platforms.

Advanced Navigation, a global leader in assured positioning, navigation and timing (PNT) and autonomous systems, has introduced a line of defense-ready inertial navigation systems (INS) featuring integrated electronic protection (EP) capabilities.
The systems are designed to counter electromagnetic warfare threats and ensure mission continuity amid a global surge in GPS jamming and spoofing attacks.
The electronic protection range includes:
Boreas D Series, including the Boreas D50, D70 and D90 fiber-optic gyroscope (FOG)-based inertial navigation systems. Engineered for high-threat operational theaters, the Boreas D series supports multiple vehicle types and links to battlefield management systems and health and usage monitoring systems.

Maximilian Doemling, chief product officer at Advanced Navigation, said countering signal jamming and spoofing requires solutions that are several steps ahead.
“This means embedding electronic protection into the foundation of every system,” Doemling said. “Our new electronic protection range takes our proven inertial navigation technology and combines it with advanced capabilities to detect and neutralize interference in real time.”
The systems provide real-time detection of GPS interference, cryptographic validation to identify spoofing and adaptive filtering to sustain positioning integrity. A built-in spectrum analyzer provides real-time monitoring of the radio frequency spectrum with configurable notch filters.
The electronic protection range incorporates dual-antenna, multi-band GPS receivers supporting up to three frequency bands for improved satellite visibility in high-interference zones.
The systems are engineered for integration into new and legacy defense platforms including combat vehicles, unmanned ground vehicles, artillery, counter-unmanned aircraft systems, radar pointing systems, intelligence, surveillance and reconnaissance payloads, unmanned aerial vehicles, unmanned surface vehicles and autonomous underwater systems.
In September 2024, a coalition of U.S. aviation and maritime stakeholders raised concerns over the surge in GPS jamming and spoofing incidents affecting civilian airspace and international shipping lanes. The Federal Communications Commission announced plans to initiate a formal inquiry into alternative and redundant positioning, navigation and timing systems.
Australia has established the Joint PNT Directorate, now at initial operating capability. In the U.K., the government is working to implement a framework for greater positioning, navigation and timing resilience.
Advanced Navigation backs its solutions with a three-year warranty. All Advanced Navigation solutions are free of International Traffic in Arms Regulations restrictions.
The Boreas D50, Boreas D70, Boreas D90 and Certus Evo are available for shipment.

OxTS has released WayFinder, a new localization solution designed for use in GNSS-denied environments. The system combines a GNSS/INS system, onboard processor, lidar scanner and two cameras to enable accurate positioning in areas with limited satellite coverage, such as urban canyons and underground tunnels.
Precise localization data is crucial for various industries, including autonomous navigation, automotive testing and sensor data georeferencing. However, obtaining accurate positioning information in areas with weak or unavailable GNSS signals has been a persistent challenge. WayFinder is designed to operate with minimal setup, requiring only basic configuration before use. The system’s key feature is Lidar Boost, a new software technology that enhances GNSS/INS performance in environments with unreliable satellite signals.
Lidar Boost employs advanced algorithms to process data from the integrated Lidar scanner, compensating for missing or erroneous GNSS updates in real time. This allows WayFinder to maintain high-accuracy localization in areas with limited satellite coverage and ensure smooth transitions between GNSS-supported and GNSS-denied environments.
The system can be used across multiple sectors. In ports, it can provide precise localization for autonomous vehicles operating among stacked shipping containers. In mining, it can support navigation for both underground and surface vehicles. WayFinder also offers a solution for indoor automotive testing without the need for fixed infrastructure. Surveyors working in areas with intermittent GNSS coverage can also benefit from its positioning capabilities.
