Wingcopter’s authorized partner in Japan, ITOCHU Corporation, has signed a Memorandum of Understanding (MOU) to collaborate on the practical use of Wingcopter’s long-range drones in aerial surveying together with PASCO Corporation and YellowScan Japan.
The companies initially plan to use the Wingcopter 198 in disaster management where drone-based surveying is playing an increasingly important role,
to create hazard maps and monitor ground deformation as part of effective pre-disaster prevention,
to gather information and assess damage in the event of a disaster, and
to measure terrain changes and develop recovery plans during post-disaster restoration.
According to Wingcopter, carrying out these tasks is easier and less risky with fixed-wing drones such as the Wingcopter 198 than with traditional human or aircraft-based methods.
About 70 percent of Japan’s land consists of mountainous and hilly terrain, with steep slopes and short, fast-flowing rivers. Conventional multicopter droneswould not be suitable for such tasks as they are limited in range and coverage compared to the Wingcopter 198.

Under the MOU, YellowScan Japan’s advanced lidaer scanner Voyager will be used on the Wingcopter 198. By integrating this technology with PASCO’s extensive expertise in operational quality and safety in aerial surveying, it is possible to carry out long-distance and large-area surveys that were previously difficult to achieve without manned aircraft.
In a single 45-minute flight, the Wingcopter 198 can scan 1,000+ hectares, simultaneously capturing lidar and RGB data, allowing the system to generate an exceptionally high point density and precision. This makes it suitable even for demanding applications.
The collaboration also promotes automation and labor savings in surveying tasks, contributing to sustainable development in the surveying industry and reducing disaster risks.
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.
Quectel Jan. 7 announced that it sent letters to Telit Cinterion, Thales Group, DBAY Advisors, Liberty Bell Project and Charles Parton demanding that they stop disseminating false and defamatory statements about Quectel regarding risks associated with its products’ security and the company’s purported connections to the Chinese government.
The letters assert that Telit Cinterion, Thales Group, DBAY Advisors, Charles Parton, and entities that Parton is associated with including Royal United Services Institute and the Council on Geostrategy, and the Liberty Bell Project, have conducted coordinated disinformation campaigns against Quectel.
The letters allege that the efforts, which are designed to harm Quectel’s business using malicious falsehoods, constitute inappropriate and unfair business practices and must stop.
“Quectel believes in fair competition and responsible business conduct,” said Jaron Xu, Quectel’s chief sales officer. “We will not tolerate attempts to interfere with our customer relationships and to compete on unfair terms by spreading maliciously false statements in a coordinated fashion under the guise of independent expertise. We will vigorously defend ourselves against competitors’ unfair business practices and we will not tolerate untrue and defamatory practices targeting Quectel and its customers.”
Quectel demanded that the competitors and associates cease such conduct immediately.
Greece now has its own internet of things (IoT) nano satellite in space, the MICE-1 (Maritime Identification and Communications systEm). MICE-1 was launched Nov. 28 aboard a Falcon 9 rocket from Vandenberg Space Force Base in California, as part of the Transporter-15 mission by SpaceX.
MICE-1 is the first Greek nanosatellite specifically designed for maritime and IoT communication applications. Developed at the Prisma Electronics facilities in Alexandroupolis, it aims to bring Greek shipping — and critical operational infrastructures in natural disaster scenarios — closer to the capabilities of space.
MICE-1 will collect and process shipping and environmental data in real time using artificial intelligence and advanced encryption techniques to ensure secure data transmission and analysis. It also paves the way for Greece’s presence in the field of space applications.
With real-time data collection and secure, two-way communication, MICE-1 contributes to reducing environmental footprint and promoting green technologies in shipping.
MICE-1 is a 3U CubeSat nanosatellite equipped with an AIS receiver to record, identify and track ship signals, as well as an S-band IoT communication system. The satellite’s objective is to establish direct communication with ships equipped with LAROS technology — Prisma Electronics’ innovative platform that facilitates the operational monitoring and optimisation of ocean-going vessels.
MICE-1 enables LAROS to leverage the capabilities of space, providing new tools for sustainable and efficient shipping. The company will also use the nanosatellite to optimize and evaluate the artificial intelligence algorithms it has developed, with the aim of assessing functionality impairment, predicting behaviour and managing telemetry in line with high cybersecurity standards.
A team of specialized engineers from Prisma Electronics participated in development of the nanosatellite in close collaboration with the European Space Agency. Operation of the main ground station was supported in collaboration with Democritus University of Thrace.
To meet the requirements of the mission, Prisma Electronics collaborated with international partners in the space sector, including SpaceX, Exolaunch, EnduroSat and IC-Space.
Prisma Electronics is already planning the next phase: the development of a comprehensive satellite IoT network for use in shipping, environmental monitoring and civil protection. The MICE-1 mission demonstrates that Greece is not just observing international space developments, but actively contributing to shaping them.
Carried out under the supervision of the European Space Agency (ESA), the mission is part of the Ministry of Digital Governance’s national IOD/IOV CubeSat nanosatellite programme, which forms part of the Greece 2.0 initiative. This programme is funded by the European Union’s Recovery and Resilience Facility (RRF).
Swift Navigation is collaborating with Nvidia to enable a more scalable, cost-effective approach to autonomous driving by integrating the Nvidia Drive AGX platform with Swift’s globally referenced, centimeter-accurate GNSS positioning.
Swift Navigation offloads absolute localization to the GNSS sensor stack using its Swift Automotive Suite. The suite is a complete, modular software solution for safe, high-integrity precise vehicle localization that combines the centimeter-level Skylark Precise Positioning Service with the Starling positioning engine, software that fuses raw GNSS data and corrections with inertial sensors (IMU) and wheel odometry to deliver high-integrity, centimeter-accurate positioning (PVT).
By entrusting lane-level positioning to Swift’s high-precision stack, the vehicle’s optical sensors are relieved of the absolute positioning burden. This allows the perception stack to be optimized for obstacle detection and immediate safety, significantly reducing overall system cost and complexity.
Integration with Nvidia Drive AG
The integration is delivered through the Starling SAL Plugin for Nvidia DriveWorks. The Nvidia Drive AGX platform is the industry-standard, end-to-end platform for software-defined vehicles, scaling from assisted to fully autonomous operation. DriveWorks, its comprehensive SDK, provides a unified sensor abstraction layer (SAL) for seamless ingestion of data from all sensor types.
Swift’s new plugin acts as a drop-in component within this architecture. Sitting between the vehicle’s raw GNSS sensors and higher-layer software, such as that for localization, the plugin invisibly handles the complex mathematics of GNSS corrections and sensor fusion, outputting a clean, corrected position stream directly into the standard DriveWorks interface.
“We are removing the single biggest hurdle to widespread autonomy: the complexity and cost of localization,” said Holger Ippach, EVP of Product and Marketing at Swift Navigation. “By delivering Starling’s natively integrated, high-integrity GNSS to Nvidia DriveWorks, we are giving OEMs a direct path to globally referenced, lane-level positioning that is simple, scalable, and affordable.”
The collaboration and the Starling SAL Plugin unlock several advantages for automotive OEMs leveraging the Nvidia Drive platform:
Cloud-native ASIL safety. Skylark is an ASIL-certified positioning service built entirely in the cloud, offering scalability and reliability at a lower cost than solutions reliant on physical data centers.
Comprehensive sensor fusion. The Starling Positioning Engine delivers robust, high-integrity positioning by fusing precise GNSS with IMU and wheel odometry, ensuring continuous, lane-level accuracy even in signal-challenged environments.
Plug-and-play precision. Developers no longer need to build localization stacks from scratch. High precision is toggled on simply by adding the Starling plugin to the DriveWorks configuration.
Hardware independence. Because Starling is software-defined, Nvidia customers can achieve high performance using a wide variety of mass-market GNSS receivers, rather than being locked into expensive, proprietary navigation units.
Pre-validated integration. The Starling plugin has been rigorously tested and validated within the DriveWorks environment. This eliminates the complex, months-long burden of validating custom sensor drivers and fusion algorithms, allowing engineering teams to focus immediately on high-level path planning and control.
The Starling SAL Plugin for Nvidia DriveWorks is available now.
Today’s commercial innovation requires infrastructure that moves at the same pace.
Essence
The rise of commercial satnav
Everyday life is saturated with location-dependent devices. They are multiplying faster than ever and their requirements have surpassed what GPS can support. Innovation in low-Earth orbit (LEO) satellites have seen exponential growth in the last ten years, unlocking new possibilities in further connecting our world.
In 2016, the total number of satellites operational in space from commercial and government operators was approximately 1,500. This number had been stable for decades, with linear growth since the launch of Sputnik in 1957. Today, there are now more than 8,000 satellites operational in space — with nearly all growth happening in LEO.
There are multiple reasons why. The cost of space access has decreased with reusable rockets and greater competition. The demand for connectivity has driven deployment of multiple constellations to deliver Internet from space. Latency is extremely important in communications and resolution in Earth observation.
While innovation in LEO satellites has primarily focused on connectivity and Earth observation, there is a generational opportunity to innovate in the position, navigation and timing (PNT) infrastructure that silently powers modern life.
There are now more than ten entities working toward deployment of dedicated PNT functions in LEO, amounting to more than 2,500 satellites if every constellation was complete today. As shown in Figure 1, five of these entities have already collectively launched more than 50 satellites. This market signal is not surprising, as demand for greater precision, power and protection are becoming fulfilled with diversification in LEO.
Figure 1. Launches of LEO PNT satellites.
Essentials
Medium-Earth orbit (MEO) has been the traditional choice of satellite navigation for global systems, with GPS, Galileo, BeiDou and GLONASS all being deployed in this regime. This altitude in the outer Van Allen belts is the harshest radiation environment Earth orbit satellites are subjected to and is a major driver in the cost and complexity of the satellites. From a commercial standpoint, deployment in LEO is more attractive as the more benign radiation environment allows for the use of more commercial off-the-shelf (COTS) parts in satellite designs, facilitating volume production. With a healthy ecosystem and supply chain now developed around LEO for both satellites and launch vehicles, the opportunity for commercial PNT to set a new standard in performance and protection is open.
The time for innovation in PNT could not be more urgent. Innovators are pushing the frontiers of technology across every industry and market. Physical intelligence is proliferating in the form of self-driving cars, humanoid robotics, automated farming, unmanned aerial systems and more. As these systems begin to coexist in the real world, the tools they rely on have never been more at risk. Commercial aviation is regularly jammed in Europe and the Middle East due to ongoing conflicts. And ships at sea are struggling to adapt to an environment where spoofing is commonplace.
The commercial world has different and increasingly more stringent requirements than government-focused systems like GPS. GPS was designed primarily around military requirements and is longstanding infrastructure that is difficult to change with the myriad number of deployed devices that depend on it. This responsibility makes GPS too big to fail, but also incredibly difficult to change.
GNSS infrastructure has unlocked so much in commercial activity. There are now more devices using GNSS than the Internet, and GPS is by far the majority user of the technology (based on nearly 7 billion active GNSS devices on Earth and around 6 billion users of the Internet.) However, commercial users have limited input to the evolution of GNSS constellations, which has led to a widening gap between technology and wants, which provides for the current commercial opportunity.
Simply put, today’s commercial innovation requires commercial infrastructure that moves at the same pace to support.
Elements
Architecting LEO PNT
For a LEO satellite navigation system, many designs could be considered, as reflected in Table 1 from Reid et al. (2025) outlining current public information about systems already announced. These constellations range from government-supported systems, which could act as extensions of already deployed global or regional systems, to commercial systems that target potentially unique, independent markets.
Table 1. Comparison of dedicated LEO PNT systems, deployments, and plans. Note that satellites already deployed were verified on celestrack.org .
These constellations all have one thing in common: they aim for between 200 and 300 LEO satellites. The reason is simple: as LEO satellites have a footprint of approximately 1/10th that of medium Earth orbit (MEO) satellites, and between 20 and 30 MEOs are required for global PNT, approximately 10x more LEOs are needed to obtain similar coverage. A consequence is that in LEO, the radio energy is spread over 1/10th the area compared to MEO, which has implications for power needs at the satellite — 10x less in LEO for the same MEO power in the same band.
There is another crucial parameter to consider in LEO PNT design: spectrum. Table 1 shows that many approaches are being considered. Xona’s approach with its Pulsar constellation was centered around three major areas of commercial appeal: seamless operation with existing devices; increased native accuracy; and added resilience to jamming and spoofing. An important philosophy adopted early in the company’s culture was to not make development a science project — that is, do not reinvent the wheel, but rather upgrade the engine. GPS was a revolutionary technology, which is why it is so heavily adopted and brings so much value to the world. Therefore, stand on the shoulders of this giant to look out to the future.
Ease of integration was the first consideration, as it has been the most important aspect in accelerating adoption of any new system. And spectrum is key to Integration. By launching a new system that uses the existing L-band signals, the GNSS ecosystem producing approximately one billion new units per year can seamlessly upgrade their capability without new hardware. Xona’s first technology pathfinder satellite in 2022 validated this hypothesis. While the pathfinder mission supported two satellite frequencies already in the regional navigation satellite system (RNSS) bands — one near L-band E6 and the other in the yet unused C-band near 5 GHz — it became apparent that receiver companies were willing to develop hardware for the L-band signal, and did so quickly with their existing hardware. There was resistance and longer timelines to global adoption for C-band signals.
In response, Xona shifted the production signals to a dual L-band system, which already has nearly a dozen commercial receiver partners tracking the recently launched production satellite — some within weeks of the launch. The challenge is to choose a waveform that is near existing GNSS bands, familiar in form and function and digital signal processing techniques to what is already fielded today, and to not cause harmful interference to the existing GNSS services in orbit. The resulting design is shown in Figure 2, on the right. The key innovation was the selection of a bandwidth efficient form of quadrature phase shift keying (QPSK), which focuses the energy in the central lobe and rolls off quickly compared to a traditional binary phase shift keying (BPSK) signal, shown in Figure 2 on the left for comparison. The result is a 100x stronger signal that does not cause harmful interference to existing GNSS signals, while offering resilience through more signal power. This selection process was iterative, taking feedback from the receiver community. More information on the design and testing for compatibility can be found in Reid et al. (2025).
Figure 2. (Left) GPS BPSK-based signal waveform, and (right) Pulsar QPSK-based signal waveform.
In addition to compatibility and ease of integration, accuracy and resilience are critical design drivers. For example, farmers rely on their equipment positional accuracy to efficiently distribute seeds, fertilizer and water, reducing waste and improving crop yields. Positional accuracy also enables accurate, repeatable field operations year after year, saving time, fuel and money while protecting the soil. Because GNSS typically offers meter-level positioning, today many farmers buy positional accuracy through GNSS correction services to obtain centimeter-level positioning. The Xona architecture leverages these techniques in precise point positioning (PPP), delivering precise ephemerides direct from the space segment, and combining them with the fast motion from LEO satellites (compared to MEOs) to reduce position solution convergence times from ~10 minutes to nearly instantaneous (see, for example, Mah and O’Keefe, 2025). This geometry also boosts coverage, as correction services today typically rely on geostationary satellites and do not service high latitudes, where they would benefit missions such as mining operations for critical minerals and polar navigation.
Connectivity relies on resilient timing. Passing more data through a network means efficiently meshing data packets in synchronized manner. Telecommunications and data centers need such connectivity to function. Authentication is expected in our communications systems, which is largely unavailable in civil GNSS signals. In an age where GNSS spoofing is done to cheat at games like Pokémon Go and now more frequently for nefarious purposes, authentication becomes essential for a modern system (Anderson, 2025, and Xona, 2025a). For resilience to spoofing, Xona included not just data authentication, but also range authentication, so that users can ultimately authenticate their position.
Defense applications require resilience to jamming. World conflicts, particularly currently in Ukraine and the Middle East, have showcased GNSS vulnerabilities in the presence of widespread GNSS jammers. However, this problem is no longer only a defense issue. In 2025, nearly 123,000 commercial flights in Europe were disrupted between January and April alone by GNSS jamming (GPS World, 2025). For resilience to jamming, one method is more power. LEO being 20x closer to Earth than MEO affords nearly a 10x boost in power for the same power transmitted at the satellite. Xona’s target was 100x more power to the end user to significantly reduce the effective range of a jammer by more than six times as shown by recent field trials. Such a transmission power translates to a >97% reduction in affected area and means threats shift to larger and less practical platforms for adversaries, i.e., from requiring handheld devices to backpacks or even truck-sized jammers.
More signal power also has implications for indoor positioning. Internet of things (IoT) devices such as asset trackers are commonly affected by signal obstruction and attenuation during transit, particularly in indoor environments, urban canyons, under foliage, or when obstructed by vehicles and cargo. Warehouses, shipping containers, and other constraints limit where position can be determined. Even coarse indoor positions can support operational intelligence for asset management.
Launching LEO PNT
Pulsar is designed to launch in stages as shown in Figure 3, which unlocks capability in tranches that expands the number of features and ultimately the user base. While Pulsar will achieve persistent coverage across major markets at the deployment of 16 operational satellites, earliest customers in time transfer will see value from Pulsar much sooner as an independent source of timing synchronization for devices with holdover clocks. At 16 satellites, Pulsar will achieve persistent 1-satellite-in-view service, unlocking precise time transfer and coarse positioning for stationary users, including indoors. Pulsar also provides a link to stream GNSS corrections, building on a partnership with Trimble. Full resilient positioning will come online with GPS-level satellite visibility. First in the midlatitudes, with 192 satellites, and then globally with the deployment of an additional 66 satellites into polar orbit, bringing the total to 258 operational satellites.
Xona launched its in-orbit-validation stage in June 2025 with Pulsar-0, the first production-class satellite representative of the scaled capability in terms of signal modulation, power and features. Pulsar-0 allowed for performance validation of the complete system, not just of the payload in space but also the tangible benefit to users on the ground. For scale, Figure 4 shows the 150 kg class satellite pre-launch, including its integration on the Falcon 9 launch vehicle. Launch cost has been become more accessible, unlocking the ability to launch larger spacecraft by commercial entities, which can have larger positive impact on the ground (Xona, 2025b).
Figure 4. Xona’s first production satellite Pulsar-0.
LEO PNT on-orbit
In almost 6 months since launch, Pulsar-0 has been tracked in more than 6 countries, 12 third-party receiver protypes, and has achieved several performance milestones that signal the groundbreaking capability Pulsar will deliver to users everywhere when the full constellation is operational. Early performance tests are built to showcase the value and features most important to commercial users in realistic settings.
Accuracy. Figure 5 illustrates a signal-in-space user-range-error (SISRE) of 43 mm — about the diameter of a golf ball. This performance represents a more than tenfold increase in accuracy compared to that reported by GPS (Refro et al., 2024). The implication is an ability to natively perform PPP at the centimeter level, without an additional data link or correction layer.
Figure 5. Estimate of SISRE for Pulsar-0 ranging signal compared with nominal GPS.
Security. Xona is the first organization to show pseudorange authentication from orbit, accomplished using the Pulsar-0 satellite within weeks of the launch (Anderson, 2025). Pulsar is built from the ground up to be secure by design, combining cryptographic authentication of both navigation data and satellite ranging signals with rapidly authenticated signal verification — aiming for a time-to-authentication of approximately four seconds. This layered security significantly raises the technical and financial bar for would-be spoofers. A spoofer spoofing a single satellite continuously should succeed in fooling one second of a Pulsar receiver’s ranging once every 130 years (Xona, 2025a).
Jamming. Pulsar-0 signal testing has been conducted under live-sky jamming conditions at several jamming events, including Jammertest 2025 in Norway. These campaigns confirmed that using the Pulsar X5 signal can reduce the effective radius of a jammer by 6.3 times as compared to GPS L5 — in other words, less than 3% of the affected area compared to GPS. The same targeted power, bandwidth and type of jammer waveform was used against GPS and Pulsar, including center frequency. For context, Figure 6 shows the implications for a 1 Watt jammer scenario in San Francisco and the reduction brought by a 6.3x reduction in radius.
Figure 6. ffective jamming areas for Pulsar X5 and GPS L5 from a 1 W jammer in San Francisco based on Jammerfest 2025 test results.
Indoor. Data were collected for several navigation passes per day at multiple locations, including indoors. These include passes at Xona headquarters in Burlingame, California, and its office in Montreal, Canada. The most challenging indoor environment was Montreal, on the third floor of an industrial and primarily concrete building with two floors above. Figure 7 shows the Pulsar-0 power profile during a typical pass, peaking at the highest point in the sky. This structure is an artifact of the antenna gain pattern used in this mission. Designed for a higher altitude for deployment of later satellites, the pattern will be more isotropic with future satellites launched near 1100 km altitude compared to Pulsar-0, which is closer to 500 km. Near apex, the signal penetrates indoors, and this short segment proves to be sufficient for indoor positioning for stationary users. Leveraging techniques based on Doppler and including pseudorange, early results indicate sub-10 meters both outdoors and indoors.
Figure 7. Comparison of Pulsar and GPS signal strengths on roof and indoors at the Xona Montreal office.
EVOLUTIONARY
The coming years will be about gaining operational experience and in scaling the constellation with a near-term focus on the first batch of 16 satellites. Pulsar-0 has already confirmed its value proposition: attaining major milestones in performance including accuracy, security and jamming, but perhaps most importantly in the integration of user equipment. The next year is about working with customers in specific industries and use cases as Xona moves towards deployment of early operational service.
The future of LEO PNT is bright. Theory has evolved to prediction, which is now evolving to reality. The early results appear to lead to an exciting PNT future with LEO PNT expanding the GNSS revolution in terms of security, interference mitigation and system availability both outdoors and indoors for a myriad of current and new applications and users.

Winners of the U.S. defense Counter-small Unmanned Aircraft System (C-sUAS) Low-Cost Sensing (LCS) challenge have been announced.
MatrixSpace Inc. was selected as the overall winner and will receive the top award of $500,000. Following the overall winner, the top three performers — Guardian RF, Hidden Level and Teledyne FLIR Defense — will each receive award amounts of $100,000.
The selected systems secured a place among the 10 finalists who advanced to live testing during USNORTHCOM’s Falcon Peak 25.2 exercise, outperforming 115 submissions. The system demonstrated capability in detection, classification, localization, scalability, cost and integration readiness.
Sponsors of the award include Defense Innovation Unit (DIU), U.S. Northern Command (USNORTHCOM), Joint Interagency Task Force 401 (JIATF-401), U.S. Army, U.S. Navy, U.S. Marine Corps and U.S. Indo-Pacific Command.
“Small UAS threats are evolving faster than traditional acquisition cycles, and meeting that challenge requires capabilities that can be deployed at speed and scale,” said David Payne, acting director of DIU’s Autonomy Portfolio. “The selected solutions show how commercial innovation can strengthen our layered defense — delivering affordable sensing that we can field widely, adapt quickly, and keep the warfighter ahead of the threat.”
The MatrixSpace platform combines ultra-low SWaP-C radar, AI-driven edge intelligence, and distributed networked CUAS powered by AiCloud. During the evaluation, it successfully detected, tracked and classified every sortie flown —including RF-dark fiber FPVs, commercial drones, and custom-built UAVs.
A scalable, distributed approach to counter-UAS sensing
The LCS challenge, launched in May 2025, was designed to complement existing sensor systems by identifying emerging technologies that enable broad, distributed, and resilient sensing architectures. During FP 25.2, the 10 selected finalists demonstrated solutions spanning radio frequency passive detection, active radar, acoustic sensing, optical and infrared modalities, and hybrid systems.
These technologies collectively showed potential cost savings of 50–80 percent in total cost of ownership, while still meeting key coverage and performance requirements for C-sUAS defense.
During live testing, vendors were evaluated against a variety of small UAS flown both individually and in coordinated multiples, employing diverse communication protocols. Finalists were not informed which platforms or profiles they would be tested against, ensuring performance was measured under realistic, un-scripted, and operationally relevant conditions.
Evaluated by experts and end-users, against a rigorous selection criteria,challenge winners differentiated themselves by demonstrating tailored technical strengths, high performance against threat-representative UAS targets and demonstrating a cost-effective architecture enabling deployment at scale across fixed, mobile, and austere environments.
About the LCS Challenge
The Counter-sUAS Low-Cost Sensing (LCS) challenge sought to identify emerging sensor solutions that could:
expand detection coverage
reduce total lifecycle cost
integrate seamlessly into joint C2 architectures
provide the resilience and redundancy required to counter small UAS threats.

With HxGN SmartNet, Hexagon has built a reliable, scalable GNSS infrastructure that integrates physical reference stations, specialized software such as Leica Spider, and a secure environment for distributing precise positioning data. Supporting tens of thousands of users worldwide, SmartNet delivers the accuracy and continuity essential for daily operations across many sectors.
The MMoU signatories hope to advance resilient positioning services and strengthen geospatial capabilities for nations around the world. Through joint initiatives, they aim to:
Enhance continuity and accuracy of GNSS-based positioning services
Strengthen resilience against signal interference
Support countries in developing and maintaining geodetic infrastructure
Expand education and workforce development in geodesy.
These initiatives ultimately help end users access more consistent accuracy, higher service availability, and stronger resilience against jamming or spoofing.
The MMoU was signed by Henning Sandfort, president, Geosystems Business Area, Hexagon, and Dieter Fritsch, Hexagon’s representative to the UN-GGIM Private Sector Network, on Nov. 17.
“Joining the MMoU underscores our commitment to ensuring that accurate, dependable geospatial information is accessible to governments and organisations worldwide,” Sandfort said.
“Hexagon’s contribution under the MMoU demonstrates the importance of global collaboration between Member States, UN and the geospatial industry,” said Nicholas Brown, head of Office at the UN-GGCE. “Hexagon is a key player of GNSS technology and digital reality solutions and therefore mostly welcomed to contribute the future vision of a strengthened global geodesy supply chain.
The latest generation of Safe Pro’s AI technology will be presented at U.S. Army exercise at Fort Hood, Texas
Safe Pro Group, a developer of artificial intelligence (AI)-enabled defense and security solutions, has deployed upgraded AI algorithms to its patented Safe Pro Object Threat Detection (SPOTD) technology for drone operations in GPS-denied environments.
The newly enhanced SPOTD capabilities will be prominently featured at the upcoming U.S. Army 2026 Concept Focused Warfighter Experiment (CFWE) technology demonstration taking place at Fort Hood, Texas.
Operating on the Amazon Web Services (AWS) Cloud or at the Edge, SPOTD is Safe Pro’s patented rapid battlefield image analysis platform designed to identify and map small explosive threats such as landmines and ambush drones detected in videos collected from virtually any drone.
The ability for SPOTD to rapidly detect threats and create 2D/3D models from drones flying in GPS-denied environments was developed after real-world exercises in Ukraine at the request of end users. The integration of these new algorithms further enhances the value of SPOTD as a situational awareness tool for use in a wide array of military reconnaissance and planning operations.
SPOTD enhancements include:
Ability to process any drone video data: Turning video clips into 2D and 3D models with AI-trained explosive threat detections
Enhanced operational robustness: Operating capability in GPS and GPS/GNSS denied environments
Terrain modeling: Threat and terrain mapping in support of unmanned ground vehicles (UGVs) route planning
Rapid mapping-only mode: Mapping for intelligence, surveillance and reconnaissance (ISR) and missions that do not require AI-powered threat detections
Accelerated processing: Up to 10x reduction in processing time powered by Safe Pro’s proprietary geospatial AI algorithms.
Powering the company’s SPOTD technology is Safe Pro’s unique real-world datasets, which include high-resolution drone imagery and GPS-tagged geospatial data encompassing more than 2.2 million drone images analyzed to date, and 41,400+ threats identified across 11,400 hectares (28,000+ acres).
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.
