The draft EUROCAE document ED-348: Guidelines for the use of multi-GNSS solutions for UAS – Medium Risk is now open for comments.
Between 2019 and 2022, EUROCAE group SG-6 developed guidelines for low risk operations Sail I and Sail II (ED-301) to support the use of GNSS and show compliance with previously established safety objectives (SORA OSO#13).
SORA OSO#13 is also applicable to higher SAIL operations with a different level of assurance, which may take the form of a service level agreement (SLA) with external GNSS service providers. This changes the approach with respect to low-risk operations, so a new standard will be defined instead of evolving ED-301.
“When discussing the use of GNSS in UAS operations, the assessment cannot be limited to GNSS as an external service only, but should consider other critical aspects such as system architecture, vulnerabilities, performance analysis, receiver design or integration, among other elements,” SG-6 posted on the EUROCAE website.
Because the requirements for medium-risk operations are more demanding than for low-risk operations, the scope of the ED-348 document not only covers compliance with OSO#13 requirements — where GNSS is considered an external service to support UAS operations — but also considers other relevant SORA OSOs where GNSS plays a relevant role.
Based on this information, the guidelines cover the following OSOs in regard to GNSS support SAIL III operations:
OSO#05: UAS is designed considering system safety and reliability.
OSO#08: Operational procedures are defined, validated and adhered to.
OSO#13: External services supporting UAS operations are adequate to the operation.
OSO#23: Environmental conditions for safe operations are defined, measurable and adhered to.
OSO#24: UAS is designed and qualified to operate under adverse environmental conditions.
Interested parties are invited to review the proposed draft on the EUROCAE Workspace and complete the comment form. Non-members of EUROCAE can register and click on “Access only to Open Consultation”). Early replies are encouraged; the deadline for comments is Feb. 2, 2026.

The 5G PNT network in Santa Clara County will mark the first real-world demonstration of a 5G-powered backup to GPS
NextNav Inc., a leader in next-generation terrestrial positioning, navigation, and timing (PNT) and 3D geolocation solutions, will commence operations of a 5G PNT network in Santa Clara County, California, as early as Dec. 11.
Network operations of positioning, navigation and timing applications represent the next milestone toward commercial readiness and the mission to deliver a resilient complement to GPS.
The 5G PNT network will consist of multiple fixed base station locations using a standards-compliant 5G signal with a positioning reference signal (PRS) enabled, a standalone 5G core, and NextNav’s 3D PNT architecture. The network’s authorized technical parameters will align with those in NextNav’s proposal to optimize the lower 900 MHz band to enable a terrestrial, widescale backup to GPS that is broadly available to critical infrastructure, public safety and American consumers.
“We’re incredibly pleased to continue demonstrating our technology in a real-world operational environment,” said Mariam Sorond, CEO of NextNav. “Activating this network is a critical step in our commercialization process, proving that robust 5G broadband service and high-integrity PNT can be delivered together, at scale, using standard 5G equipment.”
The 5G PNT network will validate NextNav’s 5G PRS-based PNT end-to-end architecture under real-world conditions.
“This is the first public demonstration of a full-scale and operational 5G-based PNT in live deployment, delivering both resilient PNT and broadband service simultaneously,” said Arun Raghupathy, NextNav Co-Founder and CTO. “Through this commercialization deployment, we’re validating our 5G-based network can deliver accurate 3D location, improved timing synchronization, and enhanced resilience. This real-world deployment is critical to establishing U.S. leadership in next-generation PNT technologies.”
The 5G PNT network will support the broader adoption of 5G-based terrestrial PNT with 5G broadband capabilities for operators, enterprises and ecosystem partners. This deployment will also prove that NextNav’s software solution is ready to scale and deliver commercial PNT while serving the critical national security and public safety needs of the United States.
AeroVironment has integrated its visual navigation system (VNS) kit with the Puma Long Endurance (LE) small unmanned aircraft system, delivering GNSS-denied navigation capability to ensure mission success.
First introduced in 2022 for the Puma 2 AE and Puma 3 AE, the VNS kit uses advanced computer vision and onboard processing to deliver precise, GNSS-independent navigation. Its integration into Puma LE now extends this capability across the full Puma family for greater flexibility and resilience in degraded or denied environments.
“Assured navigation is critical to the mission, especially as GNSS becomes an increasingly vulnerable resource,” said Jason Hendrix, Vice President of Small Uncrewed Systems for AV. “By fusing visual and inertial data in real time, the system enables uninterrupted flight paths, accurate geolocation, and mission continuity in unreliable GNSS regions.”
Using a suite of downward-facing sensors, cameras and onboard computing, the VNS kit performs visual inertial odometry (VIO) to capture and analyze terrain imagery, estimating true aircraft position in real time. The system fuses continuous visual data from the cameras with motion inputs from onboard inertial sensors to calculate precise position, velocity, and orientation — allowing the aircraft to know where it is and where it is going when GNSS is not available. It automatically transitions between GNSS-enabled and GNSS-denied modes with zero pilot input, ensuring uninterrupted mission continuity in contested environments.
In September, AV announced several upgrades to the Puma LE platform that include the integration of a Laser Target Designator and the release of the Universal Gimbal Kit, enhancements that evolve Puma LE beyond ISR into a cutting-edge precision-engagement system.
“Every upgrade to Puma LE, including the addition of the VNS kit and our new laser designator and gimbal capabilities, is driven by one goal: giving the warfighter greater confidence, flexibility, and capability,” said Trace Stevenson, president of Autonomous Systems at AV. “These recent releases are a great example of AV constantly evolving our platforms to ensure they are at the forefront of technology and providing best in class capability to the warfighter.”
The VNS Kit is designed as an add-on option for new Puma 3 AE or Puma LE system orders and as a retrofit kit allowing existing Puma 2 AE, Puma 3 AE, and Puma LE customers to upgrade fielded systems. The compact two-piece add-on installs into existing Pumas with minimal impact on performance and fits within the standard Puma cases for efficient mission packout. The standard Puma LE system weighs 23.8 pounds and offers 6.5 hours of endurance, a 60-kilometer range, is inaudible at 500 feet and features tool-free payload swaps for seamless transitions between intelligence, surveillance and reconnaissance (ISR), targeting, and other mission sets.
The MOLDPOS National Positioning System in Moldova has been integrated into the European Position Determination System (EUPOS), a pan-European GNSS augmentation service.
The MOLDPOS navigational system uses both GPS and GLONASS, and now Galileo has been added, according to Anatol Ghilas, director of the Agency of Land Relations and Cadastre (ALRC) of Moldova. Ghilas said the question of integration with the European system of Galileo was often discussed, and is a step forward in promoting the positioning technology.
Creation of MOLDPOS was gradual. First, sites for placement of MOLDPOS stations were selected, then the stations were installed. Once installations were in place, the system was tested and launched. Now it is integrated into EUPOS.
Moldova had been a member of the European Position Determination System since 2008.
According to Norwegian Ambassador to Moldova Øystein Hovdkinn, Moldova and Norway are situated in opposite parts of Europe, but it did not impede establishing friendly relations. Norway provided financial aid to build MOLDPOS.
Hovdkinn said that the Government of Norway supports the program of reforms in Moldova. The project’s goal is to promote Moldova’s development as a modern country and to promote its integration in Europe.
According to Gheorghe Duca, president of the Moldovan Academy of Sciences, implementation of MOLDPOS will have a positive influence upon the country’s social, economic and scientific sectors.
“A digital map is necessary for preventing floods, for rehabilitating roads, in agriculture and in science,” Duca said, adding that Moldova is the first country on the border with the European Union that will have digital maps, expected to be available in 10 months.

Shipborne Measurements Near the Kaliningrad Border
A major new report by GPSPATRON gathered data between June 23 and Oct. 14, aboard a vessel routinely leaving the Port of Gdańsk and performing extended maneuvers in open water.
The vessel conducted multiple offshore measurement campaigns, resulting in a shipborne dataset that provides a far more accurate representation of the true GNSS environment experienced by maritime operators in the Gulf of Gdańsk. It also reveals a level of interference complexity and intensity not visible in a previous coastal study.
In the present phase of research, the GPSPatron team moved beyond land-based monitoring and installed itsGP-Probe TGE2 interference sensor directly on board a research vessel. The ship operated throughout the southern Baltic Sea, including regular approaches toward the maritime boundary of the Kaliningrad region.
By placing the sensor on a moving platform rather than a coastal location, they were able to record GNSS interference exactly as it affects real vessels — capturing signal conditions that cannot be observed from shore due to differences in radio horizon, antenna orientation, multipath environment, and proximity to potential interference sources.

Transition from classical jamming to combined spoofing-jamming interference
In contrast to the previous six-month coastal study, where all recorded GNSS interference consisted exclusively of multi-constellation jamming, the current shipborne campaign reveals a fundamentally different interference landscape.
All major events now present a dual-layer structure composed of:
GPS L1 spoofing, generating forged satellite-like signals, and
Simultaneous jamming of GLONASS, Galileo, and BeiDou.
This combined architecture forces GNSS receivers to rely solely on spoofed GPS signals while denying access to independent ranging sources. The practice is consistent with commonly used operational strategies: spoofing only one constellation (GPS) drastically reduces system complexity and cost, whereas spoofing all GNSS systems would require multiple parallel RF chains, SDR-based generators, algorithms for signal simulations and amplifiers.
Highest recorded levels of GNSS disruption
The most severe interference period occurred from late June through July, during which:
GNSS availability dropped to 83.5%,
4 days, 5 hours and 24 minutes of spoofing were recorded — by far the highest cumulative spoofing activity of the entire campaign.
The single most extreme incident took place between 1 and 3 July, with nearly 30 consecutive hours of spoofing within a 48-hour interval, posing a severe risk for maritime navigation.
In subsequent months the interference intensity gradually decreased, yet low-power and short-duration events continued to be observed.

A multi-emitter, synchronously operating interference network
Spectrogram analysis reveals that the interference does not originate from a single source but from four distinct, technologically different emitters operating in coordination:
The synchronous activation and termination of all four components indicate a centrally coordinated system, yet their differing spectral signatures, bandwidths, and stability levels confirm multiple spatially separated stations rather than a single unified installation.
This GNSS interference analysis shows interference intensity increases away from port. (Image: GPSPATRON)
Evolution of interference modulation techniques
A clear shift is observed compared to the previous study :
Previously, the dominant interference source consisted of a high-quality, purpose-engineered wideband signal with three clean constellation-matched components — an indication of modern, precisely designed jamming equipment.
In the current campaign, the prevailing interference is simpler wideband chirp jamming, a less advanced technique but deployed at significantly higher power levels.
The wideband analog-like component further shows pronounced parasitic frequency fluctuations, characteristic of older low-stability RF hardware.
This indicates a shift from high-precision jamming to a mixed environment of legacy high-power systems combined with newer spoofing capabilities.
Interference strongly intensifies offshore
A distinct spatial gradient was recorded:
In the Port of Gdańsk, interference appears weak or barely detectable.
As the vessel moves into open water, the same signals become up to 15 dB stronger.
The interference power consistently increases when approaching the waters facing Kaliningrad.
This pattern shows that — intentionally or not — the interference system affects maritime traffic far more than coastal infrastructure, with the operational impact being greatest in offshore navigational zones.

Hoptroff, a precision timing specialist, has partnered with the London Stock Exchange (LSEG) through its Hosting & Connectivity Partner Platform, which enables financial markets customers to access third-party applications and services via LSEG’s global connectivity services.
The move reflects a fundamental shift in how financial services views timing infrastructure. No longer just a technical requirement, time has become a strategic investment in cybersecurity and digital resilience.
Timing precision has long been a regulatory necessity in financial markets. Rules such as MiFID II and FINRA CAT NMS define exactly how accurate trade timestamps must be. What’s changing is the expectation that timing infrastructure itself be resilient and independently verified.
Emerging EU and US guidelines now urge firms to mitigate over-reliance on GNSS/GPS and to implement terrestrial, traceable time sources that are protected against jamming, spoofing and cyberattacks. Time is under threat, and for financial institutions, dependable time is now a core element of regulatory resilience and audit confidence.
“Partnering with LSEG is significant,” said Tim Richards, CEO of Hoptroff. “As one of the world’s most influential financial institutions, their recognition of Hoptroff’s timing solutions demonstrates the strategic importance of resilient time that is easily accessible.”
Hoptroff combines precision timing with the reliability and uptime the sector demands, then pairs it with software that makes compliance straightforward. “Everything is plug-and-play, so firms get instant access without heavy upfront infrastructure costs,” Richards said.
Hoptroff addresses both established and emerging regulatory requirements for time synchronisation. The company holds ISO 27001 and ISO 9001 certifications and exceeds the precision standards financial markets require, offering accuracy across a terrestrial network that connects directly to national timing authorities, including NIST, NPL and RISE. This allows firms to meet global financial services regulations, such as MiFID II, FINRA CAT, and the EU Digital Operational Resilience Act (DORA), without sacrificing trading accuracy or uptime.
