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.

On Nov. 11, the chair of the Z-Wave Alliance, Avi Rosenthal, published an opinion piece in GPS World, urging a delay in addressing one of America’s most pressing national security and economic vulnerabilities. I am talking about the need for a terrestrial complement to GPS. By ignoring both the urgency of the threat and the strength of the engineering analysis supporting near-term solutions like 5G-powered 3D PNT, Mr. Rosenthal argues the U.S. can afford to wait. At NextNav, we strongly disagree.
Around the world, GPS disruptions are no longer hypothetical. As this publication has documented, incidents of GPS jamming and spoofing have become routine in places like the Middle East and the Baltic states. And the increasing severity of these disruptions is spilling over into civilian life, putting us all at risk. We’ve seen the consequences here at home, too. Major airports have experienced manmade GPS disruptions of unknown origin, and farmers have seen how even temporary GPS loss can upend precision agriculture.
Whether caused by jamming, spoofing or natural disasters, the vulnerabilities are real and growing.
These threats are why the Federal Communications Commission (FCC) made it a priority to advance additional technologies and solutions as part of a whole-of-government approach to strengthen PNT resiliency. At NextNav, we are doing the hard work necessary to help enable a system-of-systems capable of delivering greater PNT resilience into America’s critical infrastructure, while Mr. Rosenthal and his allies continue to rely on flawed studies and broad mischaracterizations of our proposal. They preach delay rather than moving to the logical next step of the FCC process, specifically designed to allow the commission to fully evaluate competing technical claims.
We have filed multiple comprehensive engineering studies demonstrating that 5G operations in the lower 900 MHz band will not cause unacceptable interference to unlicensed devices. Those studies specifically examined five different unlicensed technologies, including the Z-Wave technology. To ensure this discussion is fact-based, we’d like to set the record straight.
The SIA-sponsored paper that Mr. Rosenthal cited for his unrealistic claims of interference does not hold up under scrutiny and contains a number of fundamental technical errors. As we’ve outlined in detail, NextNav’s detailed technical analysis has identified significant flaws in the Pericle paper, pointing out fundamental errors in the paper’s assumptions and methodology.
For instance, Pericle’s predicted 5G emission levels exceed levels found in theoretical free-space conditions — an impossibility that undermines the entire paper. The Pericle paper also seems to ignore how 5G positioning signals work, failing to mention comb patterns and muting that are core to the technology, and thereby further inflating perceived 5G emission levels. Attempts to reproduce Pericle’s simulations with Pericle’s stated methods and parameters yield dramatically different results, which serve as clear evidence of computational errors or faulty execution of the depicted scenario.
Perhaps most remarkably, no credible analysis could replicate Pericle’s conclusion that 5G interference would occur more than 50 percent of the time when the ostensibly interfering transmitter operates only 50 percent of the time.
The most glaring issue with the paper that Rosenthal cites is that it never directly analyzes the very devices that the security industry states are predominant in home and business security systems today. Specifically, it fails to analyze Z-Wave, the technology that, according to the Z-Wave Alliance, is utilized by more than 90% of professionally monitored security systems in North America. In fact, Z-Wave operates primarily on frequencies that are outside of the frequencies which NextNav’s proposes to use for 5G.
It is a fact that unlicensed lower 900 MHz devices today successfully coexist with a wide range of unlicensed users that operate without coordination or interference protection. Pericle never accounts for the resilience mechanisms Part 15 devices use every day, including frequency hopping, bursty transmissions, adaptive modulation, redundant paths (meshing), self-healing and other features.
Lastly, Mr. Rosenthal’s characterization of the Department of Transportation’s action also fails to mention that the DOT has already evaluated NextNav’s technology, ranking NextNav first in every category of its 2021 evaluation. In 2024, DOT awarded NextNav the largest grant, $1.8M, for Rapid Phase I field testing of PNT technologies. NextNav supports DOT’s ongoing work to advance complements to GPS, but its testing should not stand in the way of swiftly advancing solutions that are ripe for action now.
Waiting for DOT to conclude its testing of multiple additional PNT technologies before the commission acts within its authority to take the next step towards enabling one or more potential solutions not only runs contrary to a Presidential Executive Order for agencies to remove barriers to private sector investment, but also risks the same analysis paralysis that slowed deployment of resilient PNT in the previous administration.
At NextNav, we are serious about solving an urgent national security problem, and we will continue to do the hard work necessary to support the FCC’s engineering-driven decision making. The FCC is the expert authority on commercial spectrum issues, and we believe it has all of the information it needs to take the next step in this process by issuing a Notice of Proposed Rulemaking (NPRM). Issuing an NPRM would also give the FCC the opportunity to ask any remaining technical or economic questions that it may deem necessary to complete its evaluation.
It’s time to roll up our sleeves and do the hard work necessary to enable a system-of-systems approach to building great PNT resilience. The longer we delay, the more vulnerable we become.
Renee Gregory is the vice president of regulatory affairs at NextNav.
Voyant Photonics is offering new versions of its Carbon lidar platform, adding 32-line and 64-line variants designed to bring the power of frequency modulated continuous wave (FMCW) sensing to more compact, cost-sensitive, and compute-limited systems.
The new models will be on display at the upcoming Consumer Electronics Show (CES 2026) in Las Vegas (LVCC West Hall, Booth #4875). Voyant will demonstrate live FMCW sensing capabilities and provide development kits for qualified partners.
The models complement the existing 128-line configurations, enabling broader choices and customizations from the Voyant portfolio of low-cost, high-performance sensors, and optimized for industrial autonomy, robotics, drones and smart infrastructure applications.
Building on the same efficient semiconductor foundation as Voyant’s flagship Carbon platform, the new versions offer lower data rates and simplified integration without sacrificing core FMCW advantages such as velocity measurement, interference immunity, and high dynamic range.
The Carbon family represents Voyant’s most versatile and scalable lidar product line, designed using Voyant proprietary silicon-photonics architecture that integrates beam steering and coherent detection on a single photonic chip. This integrated technology will unlock mass-production economics, reduced calibration drift, and unmatched consistency from unit to unit, the company said.
The new Carbon variants extend the core Carbon platform’s advantages:
High-precision depth sensing and real time velocity
Exceptional ambient light immunity, ensuring reliability from dim warehouses to direct sunlight
Compact design for demanding industrial and mobile environments
With line resolutions now spanning 32, 64 and 128, OEMs and system integrators can tailor performance, bandwidth and compute load to their specific use cases, from agile robotics and compact AGVs to drones and embedded edge platforms.
Advanced Navigation has finalized a multi-million deal with Kongsberg Defence & Aerospace to supply more than 50 Boreas D90 fiber-optic gyroscope inertial navigation systems (FOG INS) to strengthen Kongsberg’s Protector RS4 in high-threat, contested environments.
As a strategic-grade INS, the Boreas D90 is engineered for the world’s most extreme environments, maintaining exact targeting and unwavering line-of-sight control for the Protector RS4.
The Boreas D90 was selected not only for its superior precision in GNSS-denied conditions, but also for Advanced Navigation’s proven capacity to meet demanding delivery timelines. This agility is made possible by the company’s state-of-the-art, vertically integrated manufacturing. By controlling the entire production process, from sourcing raw components to assembly and testing in simulated EW environments, Advanced Navigation can rapidly scale output on demand and guarantee schedule certainty, a critical factor for Kongsberg.

The Protector RS4 is the world’s most fielded remote weapon system, deployed across more than 30 nations and multiple domains. The highly flexible, modular system is designed to integrate a diverse range of payloads, including small and medium caliber systems and guided effectors. Its advanced, modular sensor suite (day, night, LRF) provides exceptional and customizable situational awareness.
The fully stabilized 2 + 2 axis (detached line of sight) system allows the operator to maintain focus on a point of interest, independent of platform movement or the delivery solution for the specific system in use. The Protector RS4 is platform-independent and suitable for both land and sea applications.
By integrating Boreas D90, the Protector RS4 achieves a new level of precision and survivability, sustaining locked targeting and georeferenced stability even when GNSS is compromised or denied. This enhancement positions Kongsberg’s Protector RS4 as one of the few systems globally capable of maintaining precision pointing under active electronic warfare attack.
The deal supports the Global Supply Chain (GSC) Program, an initiative by the Australian Department of Defence designed to connect local suppliers with major global defense prime contractors. Advanced Navigation is based in Australia; Kongsberg is based in Norway.
Endura Super-TCXO Delivers Superior Holdover and Ruggedized Performance for Aerospace, Defense and Industrial Applications
SiTime Corporation has launched the Endura temperature-compensated oscillator (Super-TCXO), ENDR-TTT, for position, navigation and timing (PNT) applications. Engineered for superior holdover — uninterrupted operation when GNSS is not available — and resistance to jamming and spoofing, ENDR-TTT is an ultra-stable, low-power product for GNSS receivers in aerospace, defense and industrial markets.
“SiTime’s Endura Super-TCXO, ENDR-TTT, allows us to create a multi-layer anti-spoofing methodology,” said Paul McBurney, GPS World Editorial Advisory Board member, CTO and co-founder at OneNav. “The first layer minimizes the search window, preventing spoofing because signals outside the window are never tracked. The second layer addresses exceptionally large search windows, such as in first acquisition, where spoofers can be tracked. In this case, the spoofer signals can be identified and removed due to SiTime’s ultra-stable reference clock.”
When GNSS signals are dropped because of unavailability or degradation — including signal jamming or extreme environmental conditions — holdover maintains timing stability locally to enable uninterrupted network operation. The ENDR-TTT Endura Super-TCXO provides up to 20x longer holdover and 20x better PNT accuracy, dramatically improving spoofing resistance.
“SiTime’s ENDR-TTT Endura Super-TCXO accelerates GNSS recovery by narrowing the resynchronization window, reducing spoofing and setting a new standard for ruggedized precision timing,” said Piyush Sevalia, executive vice president of marketing at SiTime. “Our latest product delivers a powerful combination of superior performance, low power and small size, that leads the industry for PNT applications.”
Additional features for SiTime ENDR-TTT Endura Super-TCXO include:
±50 ppb stability over temperature (FvT); up to 10x better frequency stability over temperature versus quartz alternatives.
-55ºC to +125ºC operating temperature range.
30,000 g operational shock; up to 20x better resistance to shock.
0.004 ppb/g typical g-sensitivity; up to 50x better than quartz alternatives.
±0.5 ppm 20-year aging—eliminates field recalibration.
Optional I2C/SPI digital pulling capability for system frequency fine-tuning.
SiTime’s ENDR-TTT is sampling now. Mass production is expected in the first quarter of 2026.
SpacePNT SA, a global provider of high-accuracy, radiation-tolerant spaceborne GNSS receiver equipment for missions ranging from Earth to cislunar orbit, has completed extensive qualification testing of its second-generation product, including vibration, shock, thermal vacuum and electromagnetic compatibility tests.
The multi-frequency, multi-GNSS receiver resulted from two European Space Agency (ESA) ARTES Competitive & Growth (C&G) development projects supported by ESA and the Swiss Space Office.
The first project enabled SpacePNT to develop an industrialized second-generation product for large-scale production targeting low-Earth orbit, LEO position-navigation-timing and geostationary orbit telecommunications constellations. The receiver includes a proprietary Precise Orbit Determination algorithm that provides sub-decimeter real-time positioning and timing aboard spacecraft. The company validated the POD algorithm in a hardware-in-the-loop environment and retrofitted it into two first-generation flight models delivered to a customer for satellite integration.
Under the second project, SpacePNT developed a Radiation Hardiness Assurance approach for long-duration missions in harsh radiation environments. ESA’s GENESIS satellite mission, which will operate in a challenging medium Earth orbit environment, will be the first to use this RHA approach. SpacePNT will supply the mission’s GNSS receiver equipment.
Though the second-generation receiver uses largely the same hardware, software and firmware technology as the company’s flight-proven first-generation product, SpacePNT performed a complete qualification campaign to validate design changes.
After passing all qualification and performance tests, SpacePNT will begin manufacturing first flight models of its second-generation products for several customers. The receivers will fly on demanding Earth observation, in-orbit servicing and space exploration missions at altitudes from LEO through medium Earth orbit, geosynchronous transfer orbit, geostationary orbit and lunar distances.
