How it works

The system is built around a network of mobile jamming and spoofing stations arrayed around a protected site, each tied into a central command-and-control (C2) unit that handles threat detection, analysis, and response in real time. IAI says the C2 architecture can run autonomously, without an operator manually directing individual stations — a design choice aimed at compressing response time when a coordinated, multi-directional attack can unfold in seconds.

HYPNOSIS works both ends of the interference spectrum. Jamming overpowers the legitimate GNSS signal with a stronger transmission on the same frequency, denying a receiver any usable position or timing data. Spoofing is subtler: it feeds a receiver counterfeit satellite signals engineered to look authentic, steering the target toward a false position without triggering any onboard indication that something is wrong. IAI says the system is built to do both across multiple frequency bands and constellations at once, and to handle threats converging from several directions simultaneously.

The company is positioning HYPNOSIS as a complement to, not a replacement for, kinetic interceptors — a “soft-kill” layer meant for situations where hard-kill intercepts become impractical simply because of the number of airborne objects. Guy Barlev, EVP and GM of IAI’s Systems, Missiles and Space Group, described it as a cost-efficient addition to a multi-layered defense concept that still includes kinetic systems.

The PNT angle

HYPNOSIS is the offensive counterpart to IAI’s ADA GNSS Anti-Jamming System, a defensive CRPA-based receiver-protection technology the company has fielded for over two decades, including reported operational use during Operation Guardian of the Walls in 2021. Where ADA is built to keep a friendly receiver locked on despite hostile interference, HYPNOSIS applies the same NAVWAR expertise in the other direction — deliberately denying or corrupting GNSS for an adversary’s receiver. For readers tracking the anti-jam/anti-spoof receiver market, it’s a useful reminder that the underlying signal-processing and RF expertise is dual-use: the same CRPA and signal-authentication know-how that hardens a receiver against jamming and spoofing informs how to jam and spoof one.

The unveiling comes as GNSS-guided drone and missile exchanges have intensified across the Russia-Ukraine and Iran-linked Middle East theaters, underscoring continued demand for layered counter-UAS defenses that don’t depend solely on interceptor inventories.

The new version keeps the original’s compact footprint — 30×28×13.3 mm, 19 grams, roughly 0.3 W typical power draw — while adding a wider ±4000°/s gyroscope range, integrated three-axis magnetometers for a full 9-DoF output, and motion-to-output latency down to 1.5 ms at data rates up to 2 kHz. The company says gyro bias stability, long-term bias repeatability, and scale-factor accuracy have all been improved over the first-generation unit.

A notable new feature is built-in vibration analysis: the IMU continuously monitors its mechanical environment and outputs a full vibration spectrum from 4 Hz to 8 kHz, including raw FFT data and summarized reports, without external instrumentation. SBG says this is intended to speed up integration, qualification, and troubleshooting for platforms operating in harsh vibration environments. The hardware also adds vibration damping and improved EMC resistance.

The unit is form, fit, and function compatible with the original Pulse-40, so existing integrations can upgrade with limited redesign. SBG’s Gaël Bielecki said the combination of small size, ruggedness, and vibration monitoring targets platforms like guided rockets, precision-guided glide bombs, and loitering munitions, while Head of Product Management Yoann Plenet framed the vibration-monitoring capability as a way to give engineers direct insight into mechanical conditions up to 8 kHz.

The Pulse-40 OEM is available now for evaluation and integration programs.

The program follows Pulsar-0’s first year in orbit, during which the satellite completed more than 350 transmission passes across four continents and returned 22 terabytes of observation data, with commercial receivers tracking its signals from Finland to Australia.

The inaugural Pulsar Verified cohort includes Trimble, which is bringing devices launched as early as 2018 to Pulsar compatibility, along with Septentrio (part of Hexagon), STMicroelectronics, Safran, StarNav, and Keysight. Septentrio joined Xona’s ecosystem around the time of the company’s Series C fundraise and is working to integrate Pulsar across its next-generation device lineup. Safran’s Skydel and Keysight’s PNT X, both GNSS simulators capable of modeling Pulsar constellation behavior, have separately attained Pulsar Verification, allowing developers to test against the signal before receiver hardware ships. Xona CEO Brian Manning said Pulsar Verified equipment installed in drones, robots, phones, or IoT devices will be ready to use the service as it comes online.

Xona positioned the verification program as a response to escalating jamming and spoofing incidents affecting commercial aviation, shipping, agriculture, and financial systems beyond traditional conflict zones. In live-sky jamming tests, the company said its stronger signal held where GNSS was disrupted, and that Pulsar can shrink a jammer’s effective area by as much as 95%.

The certification push follows a $170 million Series C round closed in March, led by Mohari Ventures Natural Capital with participation from Craft Ventures, ICONIQ, Woven Capital, NGP Capital, Samsung Next, and Hexagon, among others. Xona opened a satellite integration and assembly facility in Burlingame, California, in April to scale production toward a planned 258-satellite constellation, with the first U.S.-built satellites expected to launch later this year. In June, Xona signed a memorandum of understanding with Murata Manufacturing — an existing investor through its Wonderstone Ventures arm — to explore Pulsar integration into communications modules, timing devices, and industrial electronics for data centers, financial networks, and 5G/6G infrastructure.

The system draws on GNSS for primary high-precision timing, ATSC 3.0 terrestrial broadcast signals — including the Broadcast Positioning System (BPS) — as a GPS-independent complement, and network-based precision time protocols for integration with IP infrastructure.

The company positions the approach as an alternative to conventional holdover mode, in which a device runs on its own internal clock during a GNSS outage and gradually drifts from true time. By continuously cross-referencing GNSS, terrestrial ATSC 3.0/BPS signals and network timing protocols, the SDAC is intended to maintain synchronization through jamming, spoofing or satellite signal loss rather than degrading over an outage.

Madeleine Noland, president of ATSC, said in the announcement that ATSC 3.0 was built to support applications beyond video delivery, including time transfer and positioning through BPS, and called the deployment evidence of broadcasting’s role in resilient national timing infrastructure. Dean Goodman, CEO of All 6G, said the product responds to a longstanding need for a true complement to satellite timing, combining satellite, broadcast, terrestrial and network sources into a single system, and linked the effort to FCC Chairman Brendan Carr’s public emphasis on resilient PNT infrastructure.

All 6G said the SDAC is designed and manufactured in the U.S. under the company’s no-Chinese-chip policy, targeting 5G/6G networks, data centers, power grids, financial systems, defense applications and other critical infrastructure requiring assured PNT. The device is available now for evaluation and deployment.

For Canada’s Calian, the answer begins with the best possible GNSS reception. Speaking with Inside GNSS at Eurosatory, Goran Jedrejčić, Head of Sales for Europe at Calian Advanced Technologies, described a company that has spent decades building high-performance GNSS antennas and is now applying that expertise to the growing challenge of jamming and spoofing.

Calian employs roughly 5,000 people worldwide and operates across sectors ranging from defense and space to healthcare and nuclear applications. Jedrejčić represents the company’s GNSS division, which traces its roots to Tallysman Wireless. “Tallysman was very well known in high-end applications and high-performance applications,” he said. “That group was taken over by Calian some four years ago, but nothing about our quality has changed.”

The group’s focus is research, development and manufacturing of GNSS antennas and increasingly, smart antennas with integrated receiver technology. “‘Smart’ means the receiver is already deep inside,” Jedrejčić said. The system integrates processing electronics directly within the antenna assembly. “You see a small footprint. There is no extra box you need to place somewhere, no extra cables. This is what’s coming on unmanned platforms.”

Manufacturing, ranging from small antennas to complex anti-jamming antennas, remains concentrated in Canada, something Jedrejčić views as both a quality and supply-chain advantage. He believes technical performance must be matched by dependable manufacturing and logistics. “If you think about it, the supply chain is very important,” he said. “If you’re able to be a reliable supplier and having all our manufacturing in a country like Canada, it means we can ship very fast. That’s a big deal nowadays.

“We focus mostly on L-band, on GNSS, Iridium, that kind of frequency range, and specialized high-end antennas, to deliver the best signal integrity,” he said. “We put a lot of effort into getting the best possible performance, high accuracy for positioning.” And that emphasis has naturally grown to encompass resilience.

Small size, low power, high resilience

“We have fixed radiation pattern antennas [FRPAs] which mitigate everything on the horizon,” Jedrejčić said. “So if there is a horizon-based jammer or spoofer, it will basically ignore that.” Additional protection is provided by filtering technologies designed to reject interference before it reaches the receiver. “It’s called XF+ filtering,” Jedrejčić said, “which again makes your system very, very resilient.”

Another clear differentiator for the company, he said, is the focus on size, weight and power. “What we have that is quite unique is a specialized CRP [controlled reception pattern] antenna which is extremely light, extremely low power consumption while still showing excellent performance.” That combination is increasingly important for unmanned systems operating on limited power budgets. “Our four-element CRPA consumes 0.7-watts of power,” he said. “A comparable conventional antenna is about 15 to 20-something watts, so that’s a really big difference.”

The Calian portfolio is finding applications across a remarkably wide assortment of platforms. “You can see us from water up to space,” he said. “We are in submersible platforms, as well as on the sea surface, in many ships. We are of course on every land platform, and we’re also in satellites.”

As interference incidents continue to draw attention across Northern Europe, one particularly relevant application for Calian customers is maritime navigation in the Baltic region, where resilient PNT capabilities have become an increasingly important operational requirement.

For Jedrejčić, the company’s move into defense-oriented GNSS solutions represents less of a pivot than a natural evolution. “We have been doing high-precision antennas required in geospatial applications since the beginning, in drones doing photogrammetry, for example, where you need that high precision. We started there,” he said, “and over time we have added superior filtering and other resilience solutions.”

The company’s customers have undergone a similar transformation. “Many companies, many drone builders, have gone from civilian to defense,” Jedrejčić said. “We’ve just followed that. We’ve been with them the whole time.”

CMFF, established as an Army program of record in April 2025 under the Program Executive Office Command, Control, Communications, and Network, is designed to converge multiple legacy stovepipe systems into a single chassis inside ground and aviation platforms. The chassis integrates capabilities including Assured PNT, tactical communications waveforms, command and control, and force protection electronic attack systems through plug-in cards that can be swapped based on mission requirements. 

In September 2025, the Army selected General Dynamics Mission Systems and Pacific Defense as the two lead developers for CMFF prototype systems. Pacific Defense’s lane is the APNT plug-in card. The Block 2 APNT PIC is a rugged 3U VPX card aligned to the Sensor Open Systems Architecture and CMOSS, fusing data from GPS, alternative navigation signals, inertial sensors, and platform vehicle data to maintain position and timing awareness in contested and GPS-degraded environments. It builds on a Block 1 predecessor developed through prior Army contracts and internal investment.

Under the multi-phase, multi-year program, Pacific Defense will design, build, and test prototype quantities to support Army system integration and test activities. While the initial focus is mounted ground and aviation platforms, the company describes the solution as applicable across airborne, ground, and maritime systems. Primary work will be conducted at facilities in Cedar Rapids, Iowa; Mukilteo, Washington; Sunnyvale, California; and El Segundo, California.

The antenna delivers peak gain of up to 1.5 dBi, approximately 50% efficiency across both bands, and an axial ratio of around 4 dB, with stable right-hand circular polarization. It supports GPS, Galileo, GLONASS and BeiDou. The passive variant uses a pin-mount configuration optimized for a standard 70 mm x 70 mm ground plane. The active AGVLB208.A ships with 1.13 mm micro-coax cable and an I-PEX MHF I connector.

Target applications include UAVs, autonomous delivery robots, precision agriculture, telematics and fleet tracking. Taoglas says dual-band operation reduces multipath interference for more reliable centimeter-level positioning in complex RF environments.

An active SMD variant with integrated electronics designed for high-volume automated manufacturing is planned for later this year. The GVLB208 series is available now through Taoglas and its authorized distributors.

Announced June 17, Kestrel integrates Honeywell’s HG3900 MEMS Inertial Measurement Unit with an M-code receiver and a multi-GNSS receiver in a package the company says is 40 percent smaller and lighter than comparable EGI products on the market. The M-code capability provides access to the military GPS signal’s enhanced anti-spoofing and anti-jam protections, while the multi-GNSS receiver broadens the available constellation coverage under nominal conditions. When external signals are unavailable, the INS layer maintains self-contained navigation continuity.

The system is intended primarily for Group 2 and 3 collaborative combat aircraft and loitering munitions, where the combination of SWaP-C constraints and GNSS-denial risk is most acute, though Honeywell notes applicability to crewed platforms with similar constraints. The company claims up to 80 percent improvement in navigation accuracy over legacy systems and cost reductions of up to 50 percent — both figures are company-sourced. Kestrel will be available in non-ITAR configurations for international defense and commercial operators.

“This system helps operators maintain mission objectives in environments where legacy GPS systems are lagging behind,” said Matt Picchetti, vice president and general manager of Navigation & Sensors at Honeywell Aerospace. Honeywell has produced more than 60,000 EGI units since pioneering the technology in the mid-1990s.

For Inertial Labs, the Virginia-based inertial navigation specialist acquired by VIAVI Solutions in 2025, that challenge has become the central driver of product development.

Speaking to Inside GNSS in Paris, Inertial Labs Sales Engineer Jackson Williams said his company has spent more than two decades refining inertial technologies while steadily expanding into sensor fusion and assured navigation. “We’re kind of a 25-year overnight success,” he quipped. The company started in 2001, based in Northern Virginia. “We also have manufacturing in Rapid City, South Dakota, and another R&D office in Kiev, Ukraine,” Williams said.

Over the past two decades, the company has evolved from a sensor manufacturer into a provider of complete navigation solutions. At the heart of that portfolio are gyroscopes and accelerometers, the foundational sensors that measure rotational and linear motion. Those are integrated into inertial measurement units (IMUs), which then form the basis of increasingly sophisticated inertial navigation systems.

Core competence

Williams summarized the company’s mission simply: “We do GPS&I, that is GPS plus inertial navigation, for autonomous vehicles. Starting with the base level sensors, we build our IMUs, and then create more complex inertial navigation systems out of those.” That focus has naturally led the company toward sensor fusion, using further data sources to constrain drift and improve overall navigation performance.

“Our main selling point and our kind of specialty is sensor fusion,” Williams said. “So we bring in aiding forms of data, such as air data computers, magnetometers for heading, fiber optic and man-time use, and low Earth constellation satellites for assured position and navigation and timing.”

Multiple aiding sources help constrain inertial drift and improve solution integrity. By fusing diverse, independent measurements, Inertial Labs seeks to maintain navigation performance in degraded environments, a sensor-diversity approach that Williams described as central to the company’s strategy.

“We bring in things like radio as well, line of sight, time of flight, time of arrival data,” he said. “We fuse these all together, curate them to our customers’ requirements, specifications, and support them when they’re on. We like to be very hands-on with our projects.”

Where it matters

Electronic warfare systems deployed particularly in Ukraine have demonstrated how vulnerable GNSS signals can be to interference. Modern assured-PNT architectures increasingly depend on multiple complementary sensors working together.

One example of a key aiding source is Inertial Labs’ miniature Air Data Computer (ADC). Designed for low size, weight and power consumption, the ADC provides airspeed, altitude and atmospheric measurements that can be fused with inertial data. For unmanned aircraft operating in dynamic flight conditions, those measurements provide an additional reference that helps maintain navigation accuracy during GNSS degradation or loss.

The war in Ukraine has also had a direct influence on product development. Inertial Labs’ Kiev office, originally established in 2006 as a conventional R&D center, now plays an important role in testing and validation. The value of that operational feedback has been significant. “All of our products are battlefield tested and qualified, vetted through our people in Ukraine,” he said. “And with everything that’s going on there, we’re getting a lot of feedback. That’s been a large factor in driving our innovation and our improvements in our devices.”

For many of the companies we met at Eurosatory, the war in Ukraine has become an unprecedented laboratory for navigation technologies. GNSS denial, electronic attack and contested electromagnetic environments have shifted inertial navigation from a backup capability to a central component of military positioning architectures.

Partnering in space

The emphasis on multiple, complementary navigation sources is also reflected in Inertial Labs’ work with the Iridium company. Iridium operates a global low-Earth-orbit (LEO) satellite constellation whose signals are increasingly being explored for resilient PNT applications. LEO-PNT satellites operating in low Earth orbit transmit significantly stronger signals than traditional medium-Earth-orbit GNSS constellations. Inertial Labs’ partnership with Iridium emerged publicly in 2026 with the introduction of IRINS, a system that combines Inertial Labs’ tactical-grade inertial sensors with Iridium’s LEO satellite capabilities.

Despite defense dominating current demand, Williams emphasized that commercial applications remain important. “Right now our main market obviously is the defense space and things of that nature,” he said. “But our IMUs are industrial grade up to tactical grade, so there is a portfolio, or a space in the portfolio for your commercial base use cases.”

He pointed specifically to the company’s LiDAR payload business. “That payload is called RESEPI and is used primarily in the commercial space, meaning farming, construction, things of that nature,” Williams said. Whatever the application, whether it’s about supporting battlefield autonomy, or infrastructure mapping and precision agriculture, the underlying requirement remains the same: reliable motion sensing and navigation in challenging environments.

Eurosatory 2026 showed clearly what our readers already knew – assured PNT is now a necessity rather than a specialized capability. Listening to Williams, a consistent case emerged: the future of navigation will not depend on a single sensor, signal or satellite constellation, but will require the ability to combine and interweave the widest available selection of them.

SkyBarrier is designed to jam all four major global navigation satellite systems simultaneously: GPS, GLONASS, Galileo, and BeiDou. HENSOLDT states the jamming effect covers both civilian and military signal variants, including encrypted signals, across the full range of currently relevant frequency and coding variants.

The system is built around rapid deployment: HENSOLDT says two operators can complete setup — including mast assembly and cabling — within minutes, with activation via a mechanical front-panel switch requiring no software configuration. The complete system consists of a single portable electronics unit, an extendable telescopic mast, and associated accessories.

HENSOLDT designed SkyBarrier for incremental upgradability, stating that new signal types can be added by replacing individual components rather than the full system. The company also notes a minimal physical interface profile — three hardware interfaces with no external data communication pathways — as a deliberate cybersecurity measure.
