ComNav Technology has introduced the Jupiter Laser RTK, which is designed for surveying and stakeout operations. The system offers a range of up to 50 m with centimeter-level accuracy and eliminates the need for traditional poles for efficient performance in routine and complex environments.
Equipped with a global night vision camera and laser technology, the Jupiter Laser RTK maintains high efficiency even in low-light or nighttime conditions. Its laser remains visible in the dark, enhancing usability during survey and stakeout tasks. The system also features visualized capabilities through a handheld data collector with an intuitive interface. Users can easily view point positions and follow directional arrows and real-time distances via Survey Master software’s 3D visual interface to accurately mark stakeout points.
The dual-camera system further enhances precision by guiding stakeout paths with a front camera for long-distance views and switching to a bottom camera for close-range detail. A flashing laser replaces traditional walkie-talkies near stakeout points, while visualization compensates for the laser’s invisibility in bright light or over long distances. These features improve efficiency by up to 30%.
Jupiter Laser RTK incorporates cutting-edge technologies such as the K8 board, which tracks up to 1,668 channels across all satellite constellations for reliable positioning. Its Super Datalink supports a 15 km working range and full-protocol compatibility, while Auto IMU provides tilt compensation up to 120° without manual initialization. Designed for durability, the system is waterproof, drop-resistant, and equipped with long battery life, ensuring reliable performance in diverse environments.
All three organizations are United Nations agencies and have previously issued similar statements independently. This is the first time they have spoken on this in one voice.
In 2020, ICAO issued a letter to all member states urging them to “strengthen CNS systems resilience and mitigate interference to GNSS.” It contained 13 recommendations resulting from three different work streams within the organization. The last of the recommendations was “… to support the multi-disciplinary development of alternative positioning, navigation and timing (APNT) strategy and solutions to complement the use of GNSS in aviation in coordination with ICAO and airspace users.”
In 201, IMO issued a circular on deliberate GNSS interference.. It called on nations to prevent interfering transmissions coming from their territories, issue warnings about known interference, and consider taking actions to prevent unauthorized interfering transmissions.
This ITU circular urged nations to “address the critical issue” by:
Reinforcing navigation systems’ resilience to interference.
Increasing collaboration between radio regulatory and enforcement authorities.
Reinforcing civil-military coordination to address interference risks associated with RNSS testing and conflict zones.
Increase coordination between aviation, military and radio-regulatory authorities.
Retain essential conventional navigation infrastructure for contingency support in case of RNSS outages and develop mitigation techniques for service loss.
A resolution by ITU’s 2023 World Radiocommunications Conference echoed similar themes. Still, it was criticized because its cautions and prohibitions came with the caveat, stating “…without prejudice to the right of administrations to deny access to the RNSS, for security or defense purposes.”
Many observers opined that there are few reasons for nations to interfere with GNSS other than security or defense concerns, which allows malicious actors to have carte blanche. Furthermore, it was suggested that the resolution might have included language to ensure that security and defense-related disruptions do not extend beyond a nation’s borders or similar provisions.
While no specific events are cited in the statement as motivating its publication, the death on Christmas Day of thirty-nine people aboard an Azerbaijan Airlines flight could have been the reason. The aircraft was approaching a Russian airport during an intentional interference event and was apparently misidentified by Russian forces. It was subsequently damaged by ground fire and crash-landed in Kazakhstan.
The recent joint statement cites, among other international agreements and actions, the ITU Constitution, which says, “All stations, whatever their purpose, must be established and operated in such a manner as not to cause harmful interference to the radio services or communications of other Member States.”
The joint statement concludes with:
Therefore, ITU, ICAO and IMO jointly and urgently call on their respective Member States to:
Protect the RNSS from transmissions that can adversely cause harmful interference, degrading, interrupting, or misleading signals used for civilian and humanitarian purposes.
Reinforce the resilience of the systems that rely on RNSS for navigation, positioning, and timing in relation to this type of interference.
Retain sufficient conventional navigation infrastructure for contingency support in case of RNSS outages and misleading signals, and develop mitigation techniques for loss of services.
Increase collaboration between radio regulatory, civil aviation, maritime, defense and enforcement authorities.
Report cases of harmful interference affecting RNSS to the appropriate telecommunication, aeronautical, and maritime authorities and the ITU Radiocommunications Bureau to enable the monitoring of the situation.
The United Nations and its agencies are collaborative bodies that operate by consensus and through the cooperation of members. As such, they have no ability to enforce standards or compel compliance with recommendations.
The Japan Aerospace Exploration Agency (JAXA) has selected Spirent Communications to supply its lunar positioning, navigation and timing (PNT) simulation solution. The solution will support JAXA’s lunar exploration efforts and aid in developing essential navigation infrastructure for future moon missions.
Spirent’s PNT X solution allows JAXA to simulate lunar PNT services in a controlled laboratory setting before their deployment on the moon. This capability is critical for testing and validating navigation equipment for lunar missions in accordance with the emerging LunaNet specifications, which include adaptable S-band frequency solutions. The system also ensures scalability for future space exploration.
Using the PNT X system, JAXA can experiment with novel S-band signals and evaluate the performance of receivers that rely on standalone S-band Lunar PNT signals or a combination of Lunar PNT and Earth-based L-band GNSS infrastructure. The simulation of these signal combinations demands high levels of precision, which Spirent’s specialized architecture is designed to meet.
This collaboration builds on a longstanding relationship between Spirent and JAXA. In 2011, JAXA utilized Spirent’s simulation technology to verify the performance of early Quasi-Zenith Satellite System (QZSS) receivers. Since then, Spirent simulators have supported multiple advancements in QZSS.
Spirent’s lunar PNT simulation solution seeks to present new opportunities for space agencies developing lunar constellations, satellite and receiver developers and organizations planning lunar missions or seeking to establish additional PNT infrastructure on the moon.

OxTS has released WayFinder, a new localization solution designed for use in GNSS-denied environments. The system combines a GNSS/INS system, onboard processor, lidar scanner and two cameras to enable accurate positioning in areas with limited satellite coverage, such as urban canyons and underground tunnels.
Precise localization data is crucial for various industries, including autonomous navigation, automotive testing and sensor data georeferencing. However, obtaining accurate positioning information in areas with weak or unavailable GNSS signals has been a persistent challenge. WayFinder is designed to operate with minimal setup, requiring only basic configuration before use. The system’s key feature is Lidar Boost, a new software technology that enhances GNSS/INS performance in environments with unreliable satellite signals.
Lidar Boost employs advanced algorithms to process data from the integrated Lidar scanner, compensating for missing or erroneous GNSS updates in real time. This allows WayFinder to maintain high-accuracy localization in areas with limited satellite coverage and ensure smooth transitions between GNSS-supported and GNSS-denied environments.
The system can be used across multiple sectors. In ports, it can provide precise localization for autonomous vehicles operating among stacked shipping containers. In mining, it can support navigation for both underground and surface vehicles. WayFinder also offers a solution for indoor automotive testing without the need for fixed infrastructure. Surveyors working in areas with intermittent GNSS coverage can also benefit from its positioning capabilities.
Trimble and PTx Trimble have introduced Trimble IonoGuard, a new technology designed to enhance RTK GNSS signal reliability for precision agriculture applications. The system aims to improve positioning accuracy and reduce signal loss during challenging ionospheric conditions.
IonoGuard is now available for users of the PTx Trimble NAV-900 guidance controller and Trimble base stations equipped with the ProPoint positioning engine. The technology was developed to maintain RTK correction integrity and minimize positioning dropouts during periods of high solar activity.
Solar activity peaks every 11 years, with the next maximum predicted in 2025. This phenomenon can significantly impact GNSS signal stability, potentially affecting precision positioning. Solar Cycle 25, which began in 2024 and is expected to continue through 2026, may present substantial challenges with the possibility of global disruptions.
While solar cycle disturbances often go unnoticed by the public, high-precision RTK GNSS users in equatorial regions frequently experience impacts from solar activity throughout the year, which can lead to costly interruptions in agricultural operations.
IonoGuard is accessible through the latest PTx Trimble Precision-IQ firmware release. When used with compatible GNSS hardware, the system aims to deliver improved RTK performance during both routine operations and periods of solar disturbance.
GNSS researchers presented hundreds of papers at the 2024 Institute of Navigation (ION) GNSS+ conference, which took place Sept. 16-20 in Baltimore. The following papers focus on high-accuracy positioning for autonomous vehicles in various environments. The papers are available here.
High-accuracy and resilient GNSS receiver for autonomous vehicles
The G3STAR GNSS receiver, a key component of the GAMMS Horizon 2020 project, is designed to improve high-definition navigation map production for autonomous vehicles. This Galileo-based receiver leverages the constellation’s Open Service features, including the High Accuracy Service (HAS) and Navigation Message Authentication (OSNMA). The research team shared that G3STAR’s ability to obtain and decode HAS messages from Galileo E6-B signals, as well as to process OSNMA bits from live Galileo E1-B I/NAV messages, demonstrates its advanced capabilities in providing secure and precise navigation data.
Preliminary tests highlight G3STAR’s proficiency in utilizing Galileo’s new services. However, the research team shared that further evaluation is necessary to fully assess its impact within the GAMMS project. Plans include validating the HAS data’s effect on navigation accuracy, conducting field tests to evaluate OSNMA availability in various environments and assessing the influence of the Chip Scale Atomic Clock on receiver performance. Additionally, comparing the G3STAR’s performance to commercial off-the-shelf receivers will be crucial in determining its overall contribution to the GAMMS navigation system and HD map generation. These evaluations will be carried out during upcoming test campaigns, providing valuable insights into G3STAR’s potential to advance autonomous vehicle navigation.

GNSS/INS positioning software library
The autonomous vehicle industry has seen significant interest and investment throughout the past 15 years, with numerous practical applications emerging in the market. However, the technology for functionally safe GNSS/INS localization in autonomous vehicles is still not fully established. This gap is particularly crucial in safety-critical applications, where positioning algorithms must be robust against potential faults, especially in challenging environments. This paper highlights Hexagon’s Safety-Critical Positioning Solution, which addresses this need by providing both precision and safety for autonomous land vehicles.
The Positioning System is a safety-first software library that integrates GNSS signals, state space corrections from the TerraStar-X Enterprise service, inertial measurement units (IMUs) and additional vehicle sensors. This system employs an extension of Receiver Autonomous Integrity Monitoring techniques, originally developed for the aviation industry. It computes multiple navigation solutions using a solution separation technique, including an “all-in-view” solution and several subset solutions that exclude various fault hypotheses. These solutions are used to calculate Protection Levels (PLs), which provide an estimated upper bound on positioning errors, accounting for systematic biases and measurement faults. The PLs can be compared against alert limits to determine whether the navigation solution is sufficiently accurate for autonomous decision-making.

Unmanned ground vehicles in off-road environments
This paper explores the emerging potential of radar for localization in GNSS-denied scenarios, particularly in challenging off-road environments where lidar-based systems struggle. The research focuses on two distinct settings: a dense forest and an underground mine. To address the localization challenges in these environments, the team developed a pipeline that combines an adaptive extended Kalman filter (EKF) for unstructured forested regions with a factor graph approach that fuses EKF estimates and point-to-plane radar iterative closest point (ICP) measurements for structured underground environments. The results demonstrate significant improvements in localization accuracy compared to existing methods, with the adaptive EKF proving particularly effective in forested areas.
The study provides valuable insights into the integration of radar and IMU data for vehicle localization in GPS-denied scenarios. While the adaptive EKF outperformed conventional EKF in structured outdoor settings, the standard EKF showed better performance in the highly dynamic conditions of the underground mine. The factor graph approach exhibited improved tracking performance, especially in reducing lateral drift along straight trajectory segments. The research also highlights the importance of selecting high-quality ICP registrations for radar-based SLAM. These findings pave the way for future research directions, including refining adaptive EKF for varied environments, exploring radar-based navigation on feature-sparse roads and enhancing the factor graph framework to incorporate additional sensor modalities.

GNSS plays a vital role in autonomous systems, providing essential positioning, velocity and timing (PVT) information for platforms such as autonomous vehicles, UAVs and ships. However, GNSS vulnerability to spoofing attacks poses significant security risks, potentially disrupting decision-making processes in these systems. To address this issue, researchers have developed a novel approach called Clock Drift Monitoring (CDM) for detecting GNSS spoofing in autonomous vehicles. Unlike previous methods that focused on directly detecting Doppler bias from measurements, CDM indirectly monitors the adverse impact of Doppler bias on the PVT solution, overcoming challenges associated with bias extraction from raw measurements.
The CDM technique exploits user clock drift derived from Doppler positioning as a detection metric. Under normal conditions with authentic GNSS signals, the clock drift remains stable, reflecting the user’s frequency source stability. However, spoofing conditions introduce counterfeit signals with consistent Doppler bias across all measurements, resulting in abnormal clock drift variations. A Generalized Likelihood Ratio Test-based detector identifies these variations, offering a practical and flexible method for GNSS spoofing detection. Field tests have validated the CDM technique’s effectiveness in real-world scenarios, demonstrating its robustness as a solution for autonomous vehicles to counter emerging cyber threats. This method’s ease of implementation, broader applicability and inherent robustness make it a promising approach for safeguarding autonomous systems against counterfeit GNSS signals.

Located in Noordwijk, the Netherlands, the GRC independently assesses Galileo’s operations, signal quality, and user-level service performance and compares its performance with that of other GNSS.
The upcoming GRC V2 version will introduce real-time monitoring capabilities, enhancing EUSPA’s ability to oversee GNSS services. This evolution will support additional Galileo services, including:
Signal Authentication Service (SAS): Strengthening trust in Galileo signals.
Time Dissemination Service: Enabling precise synchronization for critical infrastructure.
Search and Rescue (SAR): Improving emergency response operations.
Emergency Warning Satellite Service (EWSS): Facilitating public alerts for natural disasters and emergencies.
Key operational improvements in GRC V2 include:
Enhanced monitoring using data from multiple institutions.
Real-time processing for faster user notifications.
Seamless system upgrades without disrupting operations.
Advanced cybersecurity measures integrated into a platform-as-a-service model.
The upgraded GRC is expected to be operational by 2026 without impacting ongoing functions.
