<p>On the day before the first two Celeste satellites were launched from Rocket Lab Complex 1 in New Zealand, Pietro Giordano, LEO-PNT System Manager at ESA/ESTEC, was at the 2026 Munich Space Summit, explaining the significance of Europe&#8217;s LEO-PNT system.</p>



<span id="more-196647"></span>



<p>&#8220;Celeste is a program that started not even two years ago, and we are already aiming to launch our first two satellites, what we call the IOD-1 and the IOD-2,&#8221; Giordano said. The satellites, now in orbit, are CubeSats flying at around 510 kilometers altitude.</p>



<p>&#8220;The objective of the mission is to demonstrate technology,&#8221; Giordano said. &#8220;This IOD [in-orbit demonstrator] phase is fundamental for us to master the technology, the techniques that we want to apply for future systems.&#8221; The satellites are designed to validate new positioning signals, multi-frequency capabilities, and integration with next-generation networks.</p>



<p>Giordano highlighted the wider scope of the Celeste program. &#8220;The two companies in charge of development are GMV and Thales Alenia Space France. They&#8217;re not just building the satellites. They&#8217;re also responsible for the ground segment and system-level development, including the very important specification phase, which will start as soon as the satellites are flying.&#8221;</p>



<h3 class="wp-block-heading" id="h-starting-now">Starting now</h3>



<p>Celeste will operate across multiple frequency bands, Giordano said, &#8220;moving from UHF to other bands and potentially targeting indoor applications.&nbsp;Of&nbsp;course, L-band is a fundamental and master band we all need to provide. S-band has two phases: there is the S-band allocated to RNSS [radionavigation satellite services], used by GNSS systems today. But we may explore potentially usable MSS (mobile satellite service) bands, and will leverage 5G and terrestrial networks. &#8220;We also have C-band, one of the more appealing bands for resilience,” Giordano said, emphasizing the versatility and future-proofing of the system.</p>



<p>The IOD phase lays the groundwork for an operational LEO-PNT network. &#8220;At Ministerial &#8217;25,&#8221; Giordano said, &#8220;ESA proposed the in-orbit preparation phase [IOP] that will follow.&#8221; First IOP satellites could be launched in the 2027-2028 timeframe. &#8220;When it comes to 5G and the current IOD satellites, we&#8217;re only testing the very basics, the physical layer,&#8221; Giordano said. &#8220;We will go beyond that in the IOP phase, where we plan to implement the full-scale 5G network capabilities.&#8221;</p>



<p>Looking ahead, Celeste is open to adding additional small constellations and experiments, offering opportunities for European industry and third-party participation. Giordano said, &#8220;We have a very strong ambition to bring into space operational services at European level in 2032, and we cannot do it with just demonstration satellites.&#8221;</p>



<p>With IOD-1 and IOD-2 now in orbit, ESA has taken its first tangible step toward a resilient, multi-band European LEO-PNT system, promising enhanced positioning, navigation, and timing services for the decades ahead.</p>

										<content:encoded><![CDATA[
<p>At this year’s Munich Satellite Navigation Summit, Xona co-founder and CTO Tyler Reid did something that funding announcements rarely do on their own: he made the company’s case feel immediate.</p>



<span id="more-196622"></span>



<p>Speaking the day after Xona announced its oversubscribed $170 million Series C, Reid did not dwell on venture optics. He talked instead about signal power, indoor penetration, interoperability and deployment. That matters, because for years the case for low Earth orbit PNT has been technically compelling but not yet commercially proven at scale. Xona’s new raise suggests that may be changing, and Reid’s comments in Munich made clear that the company wants the market to understand this moment not as another capital event, but as the transition from concept to operational proof.</p>



<p>The Burlingame, California-based company says the round was led by Mohari Ventures Natural Capital and included participation from Craft Ventures, ICONIQ, Woven Capital, NGP Capital, Samsung Next and Hexagon. The money, Xona says, will fund both constellation deployment and manufacturing scale-up at its new factory in Burlingame. On its own, that is a significant financing story. But heard against the backdrop of Munich, the announcement sounded less like a startup celebrating a raise and more like a company trying to establish that resilient positioning, navigation and timing is finally being recognized as an infrastructure market rather than an engineering niche.</p>



<p>That is the larger significance of the round. Xona is arguing that the next era of navigation will not be built simply by modernizing legacy GNSS at the margins. It will come from a new PNT architecture—commercially manufactured, rapidly deployed and designed from the outset for stronger signals, authentication and integration with today’s installed receiver base.</p>



<p>At the center of that vision is Pulsar, Xona’s LEO PNT system. In its product materials, the company describes Pulsar as a backward-compatible service that broadcasts alongside existing GNSS signals, with compatibility across receivers using L1 or L5 and, in many cases, an upgrade path through firmware rather than entirely new hardware. Xona says Pulsar’s X1 and X5 signals are intended to deliver 2 cm by 4 cm positioning accuracy, less than 10 nanoseconds of timing, and received power up to 100 times stronger than GPS L1 C/A.</p>



<p>In Munich, Reid gave that headline claim a more grounded form. “We typically are seeing at that apex about 20 dB difference compared to us versus GNSS,” he said. “So that 20 dB is 100 times stronger signal.” This statement reinforces one of the most important aspects of Xona’s thesis: stronger signals are not just about better nominal performance. They are about resilience, penetration and utility in places where conventional GNSS becomes fragile.</p>



<p>Reid pushed that point further when he described what Xona has already been seeing from its early on-orbit testing. “We’ve shown that we can penetrate indoors and you can get as good as a three-meter level position with just the one satellite in space,” he said. Even allowing for the caveats he included—that this reflects a stationary user and observations from multiple looks during a satellite pass—the implication is noteworthy.&nbsp;</p>



<p>That compatibility claim remains central to the company’s overall strategy. Alternative PNT concepts often falter not because the performance case is weak, but because the transition cost is too high. Xona is trying to remove that barrier by presenting LEO PNT not as a replacement that forces the market to start over, but as an adjacent upgrade that works with the GNSS ecosystem already in the field. The company says more than a dozen commercial receiver partners are already tracking Pulsar signals, with testing underway in sectors including critical infrastructure, construction, agriculture and IoT.</p>



<p>Here again, Reid’s Munich comments help sharpen the point. Speaking in response to a question about time scales and interoperability, he said, “We have that defined in our ICD to support multiple timescale offsets so that these systems do become interoperable.” That is an important detail. It suggests that Xona understands one of the fundamental barriers to adoption: the market does not want an isolated new layer. It wants a service that can integrate with existing timing references, existing receivers and existing workflows without imposing a wholesale reset on infrastructure operators and equipment makers.</p>



<p>The timing of the funding announcement also gives it added weight. In the release, Xona explicitly ties its case to the growing fragility of GNSS-dependent infrastructure, citing interference in the Strait of Hormuz, the vulnerability of GPS to jamming and spoofing, and the difficulty governments have had in adding resilience through conventional acquisition cycles. The company points as well to slow and over-budget modernization efforts in the United States. That framing is, of course, self-interested. But it also aligns with a broader shift in the PNT community: resilience is no longer a secondary requirement. It is increasingly becoming the requirement that defines system value.</p>



<p>Xona’s answer is scale. The company says its Burlingame facility will support deployment of the full approximately 300-satellite Pulsar constellation “in just a few years,” a pace it contrasts with traditional aerospace contracting. Xona is selling a model in which navigation infrastructure is built more like a modern commercial platform than a classic sovereign space program.</p>



<p>That shift may ultimately be the most consequential part of the story. For decades, GNSS has been defined by exquisite but slow-moving national systems, where capability improvements arrive over long timelines and resiliency upgrades can take years to materialize. Xona is making the opposite argument: that navigation can be manufactured, iterated and replenished at commercial speed. In the release, the company says its model could produce more navigation satellites per week at full production than the United States currently produces in a year.&nbsp;</p>



<p>Reid’s comments in Munich reinforced that execution message. “We announced yesterday that we’re fully funded to deploy the first tranche of satellites to get the first commercial service,” he said. In a sector that has seen no shortage of elegant architecture slides, that line may be as important as any performance metric. It moves the conversation from theoretical constellation economics toward a near-term operating plan. Reid added that Xona will launch six satellites this year, followed by another dozen or more next year, with an initial service phase aimed in part at industrial time transfer. Those details make the financing round feel consequential in a way that venture announcements often do not. The capital is not being raised to continue talking about the future of PNT. It is being raised to start building that future at scale.</p>



<p>The company is also trying to show that this is not a U.S.-only play. Alongside the Burlingame buildout, Xona says it is expanding in Montreal and growing a London office, while partnerships with Furuno and Topcon are meant to extend the company’s reach into timing, industrial and international markets. That global framing is important. The demand for resilient timing and positioning is not limited to defense or autonomous vehicles. It increasingly reaches into telecom, power systems, industrial automation and any sector where precise synchronization and trusted location have become operational dependencies.</p>



<p>The Furuno partnership is particularly revealing because it highlights timing as an early commercial beachhead. In that announcement, Xona says the collaboration will focus on incorporating Pulsar capabilities into Furuno’s existing product domains with an initial emphasis on industrial timing. Xona argues that stronger signals and nanosecond-level precision can be brought into systems already trusted today, suggesting that timing may emerge as one of the first markets where LEO PNT proves immediate value before full navigation-scale deployment is complete.</p>



<p>Even so, this round feels like more than another venture milestone. Seen from Munich, and heard through Reid’s remarks on stronger signals, indoor penetration, interoperability and deployment readiness, it marks a moment when the LEO PNT conversation appears to be shifting from architecture diagrams and simulation arguments toward factories, launches and market timing. For a field that has spent years talking about vulnerability, backup and modernization, that is a meaningful change. Xona’s bet—and now its investors’ bet—is that the future of PNT will belong not simply to the strongest legacy signal, but to the systems that can deliver precision, trust and resilience at the speed the modern world now expects.</p>

<p>New 90G and 250G accelerometers and 4000°/sec gyroscope ranges deliver navigation solution integrity in high-dynamic environments, supporting interceptors, missiles, and hypersonic platforms.</p>



<span id="more-196604"></span>



<p>VectorNav Technologies today announced 90G and 250G accelerometer and 4000°/sec gyroscope ranges across its Tactical Series inertial measurement unit (IMU) and inertial navigation system (INS) product line. The enhancement directly addresses urgent requirements from defense contractors and platform developers operating in high-G mission profiles.</p>



<p>Defense modernization priorities are accelerating procurements of interceptors, missiles, and hypersonic platforms that must operate through launch, interception, and aggressive maneuvering—often in environments where GPS is denied or degraded. In these conditions, navigation performance depends on the IMU’s ability to maintain solution integrity without saturating. The extended-range Tactical Series is designed to meet that requirement, providing the core inertial measurements that enable resilient position, navigation, and timing (PNT) solutions to operate through mission-critical flight phases where conventional sensors fail.</p>



<p>&#8220;The demand signal from our customers has been unmistakable,&#8221;&nbsp;said Jakub Maslikowski, VP of Business Development.&nbsp;&#8220;As platforms become faster, more maneuverable, and face increasingly sophisticated threats, high-performance inertial navigation solutions are needed at scale to meet the evolving demand. With nearly 20 years supporting these mission profiles, we know these applications—and the extended-range gyro and accelerometer will enable faster integration and more rapid fielding of reliable systems.&#8221;</p>



<p>&#8211; &nbsp;High-speed interceptor platforms</p>



<p>&#8211; &nbsp;Rapid-response strike systems</p>



<p>&#8211; &nbsp;Hypersonic and advanced maneuvering vehicles</p>



<p>&#8211; &nbsp;Counter-UAS and air defense systems</p>



<p>The extended-range accelerometer and gyroscope are available across the full VN-110 IMU and VN-210 / VN-310 INS product family, supporting applications including:</p>



<p>Next-generation precision guidanceThe extended-range configurations are drop-in compatible with existing platforms—no changes to form, fit, or function—enabling immediate upgrades without redesign.VectorNav systems are designed, manufactured, and tested at the company’s AS9100-certified Dallas facility, where the company currently produces tens of thousands of units annually. As demand for resilient PNT continues to accelerate globally, VectorNav is expanding production capacity in 2026 with a new 100,000 sq. ft. facility to support high-volume programs and R&amp;D efforts.Engineering units of the enhanced Tactical Series are available now for immediate test and evaluation.

<p>SBG Systems expands its product portfolio with the unveiling of Stellar-40, a modular and scalable inertial navigation system (INS) developed for demanding environments and mission-critical applications.</p>



<span id="more-196600"></span>



<p>Designed for land, air, and marine platforms, Stellar-40 integrates a tactical-grade IMU, a GNSS receiver, and advanced sensor fusion algorithms within a compact and rugged enclosure. The system is developed to provide reliable navigation performance in high-vibration, high-dynamics, and electronically challenging environments.</p>



<p>The development of Stellar-40 focused on two main objectives, increasing resilience in harsh operational conditions and improving production scalability. To overcome the vibration sensitivity commonly encountered in defense and industrial applications, SBG Systems implemented an innovative three-level mitigation approach:</p>



<ul class="wp-block-list">
<li><strong>Sensor-level isolation: </strong>dampers integrated directly at the IMU sensor level reduce vibrations at the source.</li>



<li><strong>Resonance-free enclosure:</strong> a specialized housing engineered to drastically minimize resonance and internally induced vibrations.</li>



<li><strong>Structural isolation:</strong> custom external dampers designed to isolate the unit from harsh vehicle dynamics.</li>
</ul>



<p>This architecture supports stable system behavior in dynamic environments.</p>



<p>Beyond mechanical robustness, Stellar-40 addresses modern electronic warfare challenges. The system incorporates a high-performance GNSS receiver designed to actively mitigate advanced jamming and spoofing threats. When GNSS signals are degraded or unavailable, the system relies on multi-sensor fusion and dead-reckoning capabilities to maintain navigation continuity.</p>



<p>Positioned as the heavy-duty counterpart to Ekinox Micro, Stellar-40 introduces a revised mechanical and electronic design intended to simplify integration and manufacturing processes. The system is suited for defense programs, robotics platforms, UAVs, and autonomous systems requiring compact, scalable navigation solutions.</p>



<p>Kaoutar, Product Manager at SBG Systems, comments:</p>



<p>“Stellar-40 was developed with scalability and integration flexibility as key priorities. The design aims to support a broad range of platforms while keeping large-scale production in mind. This product brings high-end resilience against vibrations, jamming, and spoofing into a box that teams can completely trust in real-world operations.&#8221;</p>



<p>With the introduction of Stellar-40, SBG Systems continues to expand its range of inertial navigation solutions for professional and industrial applications.</p>

										<content:encoded><![CDATA[
<p>Spain’s GMV Aerospace &amp; Defence, together with ENAIRE, has developed a cost-effective system capable of detecting and localizing radio-frequency threats to satellite navigation, including spoofing and jamming. </p>



<span id="more-196589"></span>



<p>Supported by the European Space Agency (ESA) NAVISP program, the STAGER (&#8216;Sophisticated GNSS Threats Protection&#8217;) project addresses the growing challenge posed by deliberate and accidental disruptions to satellite navigation services, an issue of increasing concern for both civil and military sectors.</p>



<p>STAGER introduces a two-part solution designed for dense deployment around critical infrastructure. The first component is the SILENT node (spoofing identification and localization for enhanced navigation and timing), a compact monitoring unit capable of detecting and characterizing GNSS interference signals.</p>



<p>Built using commercial off-the-shelf, multi-constellation GNSS receivers and antennas, the unit continuously monitors satellite signals and surrounding RF activity, using several complementary techniques to detect anomalies in the GNSS signal environment. These include analysis of carrier-to-noise density ratio (C/N0) behavior, automatic gain control trends, RF spectrum monitoring, and the dispersion of carrier-phase double differences.</p>



<p>Together, these methods allow the SILENT unit to distinguish between nominal conditions, jamming events, and spoofing attacks. The system can also estimate the angle of arrival of interfering signals, enabling localization when multiple units are deployed across a region.</p>



<h3 class="wp-block-heading" id="h-ai-in-the-fold">AI in the fold</h3>



<p>The second component is VAULT (vulnerability assessment and understanding the impact of localized GNSS threats), a server-side application that aggregates and analyzes data from the SILENT network. VAULT classifies interference events using artificial-intelligence techniques, including support vector machine and variational autoencoder models, and then estimates the location of the interference source by combining angle-of-arrival measurements with power-difference-of-arrival analysis.</p>



<p>Beyond detection and localization, VAULT evaluates the operational impact of interference events. Using terrain data and RF propagation models, the tool estimates the affected service volume and identifies airspace or operational procedures that may be degraded by the interference source.</p>



<p>The system was validated through laboratory testing and open-air trials, including experiments during the Jammertest 2025 campaign. Results demonstrated reliable detection of spoofing and jamming signals and successful localization of interference sources using measurements from multiple monitoring units. In validation tests, localization errors ranged from sub-kilometer levels to several kilometers depending on geometry and measurement conditions.Presenting the results of the project at a recent ESA-hosted event, the STAGER team said their concept supports a scalable approach to GNSS resilience. By combining low-cost monitoring nodes with centralized analysis and modeling tools, the system could enable dense monitoring networks around airports, ports, or other critical infrastructure</p>

<p>Advanced Navigation, an Australia-based developer of inertial navigation and autonomous sensing technologies, has announced new investment aimed at accelerating the development of PNT systems designed to operate in environments where GNSS signals are degraded or unavailable.</p>



<span id="more-196583"></span>



<p>The company said the funding will support expansion of its portfolio of navigation technologies that integrate inertial sensors, AI-driven perception systems and sensor-fusion software to maintain accurate positioning in GNSS-denied environments. The technologies are intended for applications across aerospace, defense, robotics and maritime operations.</p>



<h3 class="wp-block-heading" id="h-focus-on-gnss-resilient-navigation">Focus on GNSS-Resilient Navigation</h3>



<p>Advanced Navigation’s core technology stack centers on high-performance inertial navigation systems (INS) combined with advanced sensor fusion algorithms. These systems use data from inertial measurement units (IMUs), computer vision, acoustic sensors and other onboard inputs to estimate position and orientation when satellite navigation signals cannot be relied upon.</p>



<p>Such capabilities are increasingly important as GNSS disruption—whether through interference, jamming or spoofing—has become more common in both civilian and defense operating environments.</p>



<p>Chris Shaw, co-founder and CEO of Advanced Navigation, said the company’s goal is to enable autonomous systems to maintain reliable navigation even in complex operating conditions.</p>



<p>“Our mission is to deliver navigation and autonomy technologies that allow systems to operate reliably across sea, land, air and space,” Shaw said in a statement.</p>



<p>Inertial navigation systems play a central role in these architectures. While INS solutions can maintain navigation continuity without external signals, they accumulate error over time due to sensor drift. Modern navigation stacks therefore rely on sensor fusion techniques that combine inertial measurements with other inputs—such as visual landmarks, lidar data or acoustic signals—to correct drift and maintain accuracy.</p>



<h3 class="wp-block-heading" id="h-expanding-the-alternative-pnt-ecosystem">Expanding the Alternative PNT Ecosystem</h3>



<p>Demand for complementary PNT technologies has grown rapidly as governments and industry seek alternatives to exclusive reliance on satellite navigation. Recent disruptions in regions such as the Black Sea, Eastern Europe and the Middle East have highlighted the operational risks posed by GNSS interference.</p>



<p>Companies developing resilient navigation architectures are increasingly integrating multiple sensing modalities—including visual navigation, signals of opportunity and advanced inertial systems—to provide robust positioning capability when satellite signals are unavailable.</p>



<p>Advanced Navigation has focused on combining high-performance hardware with artificial intelligence-based perception systems. These technologies are intended to support autonomous platforms operating in complex environments such as urban areas, indoor facilities, underground infrastructure and subsea environments.</p>



<h3 class="wp-block-heading" id="h-applications-across-autonomous-systems">Applications Across Autonomous Systems</h3>



<p>The company’s navigation technologies are used across a range of autonomous platforms including unmanned aerial vehicles, autonomous underwater vehicles, ground robots and maritime vessels. These platforms require reliable navigation even when operating in environments where GNSS reception is blocked or intentionally disrupted.</p>



<p>Advanced Navigation said the new funding will allow the company to accelerate development and global deployment of its navigation technologies while expanding manufacturing capacity.</p>



<p>As autonomous systems become more widely deployed across commercial and defense sectors, resilient navigation architectures that integrate inertial sensing, perception and AI-driven sensor fusion are expected to play a central role in next-generation PNT systems.</p>

<p>UK company Envisage Space Ltd., working with Cranfield University and supported by the European Space Agency (ESA) NAVISP program, has developed analytical software designed to improve the reliability of GNSS positioning in dense urban environments.</p>



<span id="more-196576"></span>



<p>At a recent ESA-hosted event, Terry McLarney of Envisage Space and Cranfield University Professor Ivan Petrunin presented the results of the &#8216;RelyMap Connect&#8217; project, which&nbsp;focused on the needs of micromobility services such as shared e-scooters and bikes. These applications depend on accurate and reliable location information to enforce geofencing rules, manage parking zones and monitor vehicle movements.</p>



<p>Readers will know cities present some of the most challenging conditions for satellite navigation, significantly impacting applications that need reliable location information. RelyMap Connect addressed this challenge using predictive GNSS analytics combined with live measurement data. The system builds on Envisage Space’s RelyMap platform, which uses detailed three-dimensional city models to predict satellite visibility and expected GNSS performance at street level.</p>



<h3 class="wp-block-heading" id="h-real-time-estimation">Real-time estimation</h3>



<p>The new software estimates the expected quality of GNSS positioning in specific locations and time periods. The predictions are then combined with live, multi-constellation GNSS measurements and telemetry from connected devices to assess the reliability of the positioning solution in real time.</p>



<p>Machine-learning techniques are used to fuse predicted signal behavior with GNSS measurements, allowing the system to identify situations where urban signal conditions are likely to degrade positioning performance.</p>



<p>A key output is a &#8216;confidence factor&#8217; associated with the computed position. This metric provides an indication of how reliable the GNSS solution is under current environmental conditions and can be used to determine whether positioning is sufficiently reliable for operational tasks such as enforcing virtual parking bays or no-go zones.</p>



<p>The project team demonstrated geofence optimization in urban micromobility deployments in several UK cities. By identifying areas where GNSS performance is expected to degrade, operators were able to adjust geofence boundaries or operational rules to improve compliance and reduce false violations caused by positioning errors.</p>



<p>The software operates as a cloud-based analytical platform capable of evaluating GNSS positioning performance across large urban areas, providing a continuously updated view of positioning reliability in complex city environments.</p>



<p>McLarney said the results demonstrated how environmental modeling and data analytics can complement conventional GNSS processing for emerging urban mobility applications. RelyMap Connect partners now plan to engage with micromobility operators, regulators and city authorities to explore commercial deployment of the technology.</p>

										<content:encoded><![CDATA[
<p>Hemisphere GNSS and Calian Group have jointly introduced the A65, a next-generation GNSS antenna designed as a drop-in replacement for Hemisphere’s widely deployed A45 while adding broader constellation support and stronger interference rejection. </p>



<span id="more-196566"></span>



<p>The new model is aimed at precision agriculture, survey, marine, machine control and fixed-reference installations.</p>



<p>The A65 combines a Calian-engineered stacked-patch quad-feed antenna element and RF front end with Hemisphere’s application-level integration and field validation. It is built to deliver tighter multipath suppression, consistent phase-center variation and tracking across GPS L1/L2/L5, Galileo E1/E5/E6, BeiDou B1/B2/B3, GLONASS G1/G2/G3, NavIC L5, QZSS and L-band correction services, while reducing power consumption compared to its predecessor. </p>



<h3 class="wp-block-heading" id="h-xf-filtering-for-interference-heavy-environments">XF Filtering for interference-heavy environments</h3>



<p>A key change from the A45 is the integration of Calian’s XF Filtering technology at the antenna level. The filtering is designed to reject out-of-band energy before it reaches downstream receiver electronics, targeting interference from 4G/5G cellular, Ligado and adjacent-band emitters, broadband marine and aviation systems, and dense urban RF noise. </p>



<p>By pushing more of the interference-mitigation burden into the antenna and low-noise amplifier stage, Hemisphere and Calian are positioning the A65 for GNSS operations in increasingly congested and contested RF environments where legacy antennas can struggle to maintain clean signal quality.</p>



<h3 class="wp-block-heading" id="h-drop-in-mechanical-replacement-for-a45">Drop-in mechanical replacement for A45</h3>



<p>To ease adoption, the A65 retains the same mechanical footprint, connector location and mounting configuration as the A45, allowing existing users to upgrade without hardware redesign. At the same time, the new model adds:</p>



<ul class="wp-block-list">
<li>Expanded GNSS band coverage</li>



<li>Integrated XF Filtering</li>



<li>Improved noise figure with 2.5 dB NF and 28–30 dB gain</li>



<li>Lower power draw and broader voltage compatibility </li>
</ul>



<p>Ruggedization features include IP69K environmental protection, a high-impact LEXAN radome, robust metallic base, 15 kV ESD protection and an operating range from –40°C to +85°C, reflecting its intended use on agricultural machinery, construction equipment, workboats and permanent reference stations. </p>



<h3 class="wp-block-heading" id="h-oem-and-embedded-options">OEM and embedded options</h3>



<p>The A65 is available now through Hemisphere’s channels. For integrators that need embedded solutions rather than a finished antenna, OEM module versions based on the same Calian-engineered design are also being offered. </p>



<p>As a subsidiary of&nbsp;CNH Industrial, Hemisphere is positioning the A65 as a straightforward path for existing A45 users to gain wider multi-constellation support and stronger front-end interference protection, while maintaining compatibility with current installations.</p>

<p>Thales has introduced a new family of TopStar Galileo core modules aimed at receiver manufacturers that need secure, sovereign and jamming-resilient GNSS for defense and critical-infrastructure applications.</p>



<span id="more-196560"></span>



<p>The announcement positions the modules as building blocks for European and allied OEMs that want tighter control over their navigation supply chains while leveraging Galileo’s Open Service (OS) and Public Regulated Service (PRS).&nbsp;</p>



<h3 class="wp-block-heading" id="h-sovereignty-and-resilience-as-design-drivers">Sovereignty and resilience as design drivers</h3>



<p>On the sovereignty side, the Galileo PRS core module is explicitly aimed at EU companies seeking a standardized way to embed PRS into their own receivers, rather than buying complete black-box units. The module’s small footprint (on the order of a few inches square), low weight (around 50 g) and sub-2 W power consumption are intended to make it practical across aircraft, helicopters, drones, missiles and surface platforms.&nbsp;</p>



<p>On the resilience side, the TopStar line builds on work Thales highlighted in 2025, when it reported what it called a world first: a satellite-positioning solution combining real signals from two military constellations—Galileo PRS and GPS M-code—within a single receiver (TopStar M), further hardened by the TopShield anti-jamming front end.&nbsp;The new Galileo core modules can be read as an effort to push that architecture deeper into the supply chain, allowing more integrators to field receivers that fuse multiple secure services and front-end protection.</p>



<h3 class="wp-block-heading" id="h-target-markets-from-cockpits-to-weapons-and-critical-infrastructure">Target markets: from cockpits to weapons and critical infrastructure</h3>



<p>The likely near-term adopters include:</p>



<ul class="wp-block-list">
<li>Avionics and mission-system integrators needing Galileo-capable, PRS-ready PNT for new or upgraded cockpits;</li>



<li>Defense primes retrofitting existing platforms with more resilient GNSS front ends to cope with contested RF environments;</li>



<li>Critical-infrastructure vendors (e.g., timing and sync systems) in markets where regulators are pushing for multi-constellation, sovereign PNT options.</li>
</ul>



<p>Because the modules are meant to be embedded, they also fit into a larger European trend toward modular, common-core electronics that can be reused across programmes while meeting export-control and security-accreditation requirements.</p>



<p>With French accreditation already in place for the PRS security ASIC and decades of operational use behind the broader TopStar family, Thales is positioning these modules as a mature, defense-grade option for OEMs that want Galileo inside their next generation of receivers—without ceding control of the rest of the stack.</p>

										<content:encoded><![CDATA[
<p>Hexagon | NovAtel has introduced the GAJT-AE3, a new airborne anti-jam system designed to extend GNSS protection across all major constellations and frequencies in a compact form factor aimed at space-constrained platforms.</p>



<span id="more-196586"></span>



<p>The GAJT-AE3 is the latest addition to the company’s GNSS Anti-jam Antenna Technology lineup. The product is positioned for airborne applications operating in increasingly contested spectrum environments, where lower-cost and more capable jammers are targeting a wider range of frequencies used for positioning, navigation and timing.</p>



<p>According to the company, the GAJT-AE3 is the first anti-jam product in its class to provide full multi-constellation, multi-frequency coverage across major GNSS signals. That broader signal protection is intended to help aircraft and other platforms maintain PNT availability even as interference techniques become more sophisticated and harder to avoid through conventional approaches.</p>



<p>The system’s antenna electronics mitigate interference by forming up to seven nulls per band in the direction of detected jammers. NovAtel said that capability is designed to improve survivability in dynamic multi-jammer conditions while also supporting jammer direction finding for greater situational awareness.</p>



<p>Rather than outputting navigation data directly, the GAJT-AE3 delivers a protected RF signal that can feed both modern and legacy GNSS receivers. That architecture may ease integration for operators looking to improve resilience without redesigning downstream receiver systems.</p>



<p>NovAtel also said the unit supports all GNSS frequencies as well as L-band corrections and Iridium PNT. The company is targeting a range of airborne and defense applications, from unmanned aircraft to more complex weapon systems, where size, weight and integration constraints can limit the use of larger assured-PNT hardware.</p>



<p>In a statement, Stig Pedersen, president of Hexagon’s Aerospace &amp; Defence division, said the new system is intended to extend the company’s anti-jam portfolio for platforms where space is limited while increasing both signal coverage and multi-jammer awareness.</p>



<p>The GAJT-AE3 can be paired with antennas from Hexagon | Antcom’s portfolio, with custom antenna options also available. NovAtel said the system is now commercially available.</p>
