The Federal Communications Commission (FCC) is investigating whether the use of Russian and Chinese foreign satellite systems by U.S. mobile phones and other devices poses security threats.
The FCC has concerns that U.S. handheld devices are receiving and processing GNSS signals from satellites controlled by foreign adversaries in violation of commission rules.
The FCC is seeking answers from handset manufacturers Apple, Google, Motorola, Nokia, Samsung and others that collectively cover more than 90% of the U.S. smartphone marketplace.
“There is no established record of what security threats, if any, these signals carry and whether the manufacturers of handheld devices are processing these signals in violation of the Commission’s rules,” an FCC spokesperson said in a statement.
Representative Mike Gallagher, chair of the U.S. House Select Committee on the Strategic Competition Between the United States and the Chinese Communist Party, wrote FCC Chair Jessica Rosenworcel earlier this week raising concern about reports that U.S. cell phones were receiving and processing signals from Chinese and Russian satellites.
The FCC has only approved U.S. phones to receive and process signals from the U.S. Global Positioning System (GPS) and the European Galileo GNSS.
CHC Navigation (CHCNAV) has released the RS10 handheld SLAM lidar laser scanner integrated with a full real-time kinematics (RTK) GNSS receiver. Designed to improve efficiency across a wide range of mapping and surveying applications, the RS10 seeks to provide professionals with a versatile, all-in-one tool for capturing 3D geospatial data in both outdoor and indoor environments.
The device integrates a GNSS smart antenna for RTK positioning accuracy even in challenging environments. It delivers 5 cm measurement accuracy by fusing high-precision lidar, RTK, laser and visual SLAM using three HD cameras. It uses a powerful onboard processor for real-time georeferenced point cloud generation in the field. Users can receive instant feedback, which allows them to adjust while scanning. Large sites up to 13,000 square meters can be mapped in real time.
The integration of high-precision GNSS and SLAM technologies eliminates the need for traditional loop closure, which often complicates the data collection process for handheld scanners. Users can freely scan target areas without having to return to previous locations, which can streamline field data capture and significantly reduce time spent in the field.
u-blox has introduced the F10 dual-band GNSS platform. It combines L1 and L5 bands to offer enhanced multipath resistance and meter-level positioning accuracy. The platform caters to urban mobility applications, such as aftermarket telematics and micro-mobility.
Applications that use GNSS receivers for accurate positioning are on the rise. Yet, current receivers do not fully perform in urban areas. Accurate and reliable positioning in dense urban environments — where buildings or tree foliage can reflect satellite signals — requires GNSS receivers to mitigate multipath effects. The L5 band’s resilience to these effects aims to improve positioning accuracy. Combined with the well-established L1 band, an L1/L5 dual-band GNSS receiver can deliver a less than 2 m positioning accuracy (CEP50), against about 4 m with the L1 band only. The u-blox team has conducted driving tests in several urban areas and reported significant improvement over GNSS L1 receivers.
The F10’s firmware algorithm prioritizes L5 band signals in weak signal environments to provide reliable positioning accuracy, even when paired with small antennas. The platform is also equipped with protection-level technology that provides a real-time positioning accuracy estimate.
When a cellular modem is extremely close to a GNSS receiver, it can interfere with the receiver’s reception. Some F10 module models, such as NEO-F10N, MAX-F10S, and MIA-F10Q, are equipped with a robust RF circuit that allows the GNSS and the cellular modem to operate without interference.
The u-blox F10 platform is pin-to-pin compatible with the previous u-blox M10 generation for easy migration. It also supports u-blox AssistNow, which offers real-time online A-GNSS service with global availability to reduce GNSS time-to-first fix and power consumption.
The u-blox EVK-F101 evaluation kit will be available in April 2024.

The National Physical Laboratory (NPL) has marked the inauguration of the first of three innovation nodes designed to enhance the United Kingdom’s capabilities in the development of time-critical technologies. The initiative is aimed at sectors such as transport, telecommunications, fintech and quantum with the application of accurate and precise timing.
In a collaborative effort between NPL and host organizations, including the University of Strathclyde, the University of Surrey and Cranfield University, the Innovation Nodes stand as a cornerstone of NPL’s National Timing Centre Programme. It represents the UK’s nationally distributed time infrastructure and offers secure, reliable, resilient and highly accurate time and frequency data. This infrastructure is crucial for the development of new technologies in time-critical 5G and 6G applications, next-generation automated factories and connected autonomous vehicles.
Throughout the development phase, the node sites at the Universities of Strathclyde, Surrey and Cranfield have hosted feasibility and demonstrator projects funded by Innovate UK, the United Kingdom’s innovation agency. These projects have benefited from technical consultancy and access to high-accuracy timing signals, which encourage the development of new products and services. These initiatives were created as an effort to establish an evidence base for redistributing positioning, navigation and timing (PNT) data to air and ground-based autonomous systems within a smart city infrastructure. This will ensure the safety, reliability and security of autonomous transport.
NPL welcomes collaboration with industry and academia to leverage the Innovation Nodes for access to traceable and high-accuracy timing signals and promises to stimulate further innovation and development in critical sectors.
Professor Paul Griffin of Strathclyde’s Department of Physics pointed out the vulnerabilities of GNSS to jamming and spoofing, underscoring the NTC’s mission to provide robust timing for the UK independent of GNSS. The initiative includes the use of atomic clocks at Anthorn in Cumbria, aligning with UTC through the NPL Time Over eLoran (NTOL) project, led by Chronos Technology. This project demonstrates the transmission of NPL’s timebase via eLORAN and its decoding by Strathclyde’s Power Networks Demonstration Center (PNDC), which is a significant advancement in securing the country’s timing infrastructure against potential threats.
u-blox has partnered with Cellular Tracking Technologies (CTT), a specialist in wildlife telemetry and Internet of Things (IoT) solutions, in an initiative aimed at conserving Antarctic wildlife.
The collaboration has introduced a cloud-based positioning solution to monitor the activities of Adélie penguins in Ross Island, Antarctica. The venture began when Point Blue, an American wildlife conservation organization, reached out to CTT to create a tracking mechanism that could study the movements of young Adélie penguins. These birds are among the five penguin species inhabiting Antarctica and are considered crucial for environmental studies due to their sensitivity to ecological shifts caused by climate change and human activities, such as commercial fishing.
Due to the challenging conditions in Antarctica, tracking penguins required a device that was lightweight, non-intrusive, energy-efficient, and cost-effective in terms of data transmission. This was particularly important given the small size of the penguins, their rapid movement, and their extended underwater dives.
u-blox provided its CloudLocate positioning service to meet these stringent requirements, which led to the development of CTT’s Penguin Iridium GNSS tracker. The tracker is fixed to the penguins’ backs and uses one of u-blox’s compact GNSS modules. The CloudLocate service processes the positioning calculation in the cloud rather than on the device to save energy and enable prolonged monitoring periods without the need for frequent device replacements.
The tracker operates by sending a concise 50 B message, which captures essential location data during the brief moments when a penguin surfaces for air. This level of efficiency is critical in minimizing the costs associated with satellite connectivity, which is often prohibitively expensive in such remote regions.
This partnership marks an advancement in wildlife conservation technology by allowing for non-invasive, continuous monitoring of Adélie penguins and providing vital data for assessing the impacts of environmental changes. CTT aims to extend this tracking solution to a wider range of wildlife research and conservation projects to demonstrate the potential for technological innovation to contribute significantly to ecological preservation efforts.
A plane carrying British Defense Secretary Grant Shapps had its satellite signal jammed as it flew near Russian territory, the government reported on March 14.
The government said that the Royal Air Force jet carrying Shapps, officials and journalists “temporarily experienced GPS jamming when they flew close to Kaliningrad” on a flight from Poland to the UK.
The Times of London, whose reporter was onboard, said that for about 30 minutes mobile phones could not connect to the internet and the aircraft was forced to use alternative methods to determine its location.
Kaliningrad is a Russian enclave bordered by Poland and Lithuania, home to the Russian Navy’s Baltic Fleet. Prime Minister Rishi Sunak’s spokesman, Dave Pares, said “the jamming didn’t threaten the safety of the aircraft at any point.” He added that it is not unusual for aircraft to experience electronic jamming near Kaliningrad.

Working in agriculture means facing a variety of challenges imposed by nature. Unfavorable weather conditions, such as irregular rainfall, strong winds and hail, are common obstacles for producers and companies involved in the sector. Additionally, a recent rise in solar flares has caused headaches for those who rely on precision agriculture technologies, such as satellite positioning technologies, to operate farm machinery.
Ionospheric scintillation is a phenomenon that causes rapid and irregular variations in the power of radio frequency signals that travel through the ionosphere, a region of the Earth’s atmosphere that has ionized particles, which makes it capable of reflecting and refracting radio signals, such as those used in satellite communications and GNSS.
These variations in the power of radio signals occur due to disturbances in the concentrations of free electrons in the ionosphere, which various factors, including solar activity, geomagnetic events and weather conditions in the upper atmosphere can influence. Fluctuations in the electron density of the ionosphere cause distortions in radio signals, leading to fluctuations in the signal’s power and phase. Some of the consequences of this phenomenon are almost imperceptible, such as a deviation of 1 m or 2 m in the position calculated by your cell phone’s GPS receiver. When it comes to precision farming, however, a few centimeters of error in machine positioning can severely impact operations by increasing input waste, reducing efficiency and decreasing production.
Many farmers, especially in Brazil, plant and harvest two crops a year, and rely on precision farming technology to sow and harvest quickly and accurately. With an estimated production of 317.5 million tons for the 2023/24 harvest, according to the Brazilian National Supply Company (Conab), these producers have buffer time to keep their machines idle. During planting and harvesting periods, farms often operate 24 hours a day, 7 days a week, and precise positioning via GNSS is essential for using solutions such as auto-steering and traffic control. When ionospheric scintillation affects the performance of location systems, it causes delays and inaccuracies, directly impacting the productivity of farms and damaging the operations’ efficiency and profitability.
To mitigate the impacts caused by ionospheric scintillation, as well as other problems that can affect receivers, farmers have several GNSS correction options at their disposal, such as precise point positioning (PPP) and real-time kinematics (RTK). These alternatives aim to increase positioning accuracy for high-precision applications and create different levels of resilience against ionospheric interference. However, it can still affect these services, causing errors in the receiver’s position calculations. In RTK systems, which rely on carrier phase measurements, scintillation can drastically impair positioning accuracy, especially at greater distances from the base station.
To overcome scintillation challenges, PPP positioning is a more reliable option. Unlike RTK, PPP estimates ionospheric errors at the receiver’s location and does not depend on corrections from a local base station. This allows users to achieve high precision anywhere within the global coverage area, regardless of the distance from the base station. In addition, PPP takes into account the immediate ionospheric environment, making it less sensitive to changes in atmospheric activity.
A study by Hexagon | NovAtel in 2020, analyzed the ionospheric activity in the central-western region of Brazil, comparing a standard RTK positioning solution and the PPP TerraStar-C PRO positioning solution, developed by NovAtel. A 24-hour data collection captured the nocturnal impacts of ionospheric activity and yielded some insights: while RTK position performance at 10 km from the base station was degraded for many hours, showing errors of up to 25 cm, the receiver using TerraStar-C PRO corrections continues to experience centimeter-level accuracy, with shorter maximum deviations of up to 10 cm.
In summary, ionospheric scintillation is a growing challenge for precision agriculture, affecting the productivity and efficiency of agricultural operations. To minimize its impacts, the adoption of correction services such as TerraStar-C PRO has proven to be a resilient and reliable solution, allowing farmers to continue their operations accurately and effectively, even in challenging conditions. The development of increasingly advanced precision solutions is crucial to ensuring the success of agriculture.
FrontierSI, a not-for-profit research organization specializing in positioning, geodesy, spatial infrastructures and rapid spatial analytics, has released a review of Australia’s resilient positioning, navigation and timing (PNT) policy to fortify the country’s PNT infrastructure. The review, expanded upon in a new white paper and technical report, was created in response to the increasing number of cyber threats.
“PNT is an essential utility we presently have no control over,” said Joshua Critchley-Marrows, FrontierSI’s space PNT lead. “Australia’s access to PNT is intrinsically linked to satellite-delivered services from foreign-owned and operated assets, such as the USA’s Global Positioning System (GPS). Investing in our infrastructure is crucial to ensure continuous access to this critical service that underpins nearly all aspects of our daily lives.”
According to FronteirSI, the reliance on foreign satellite systems exposes Australia to significant vulnerabilities, such as recent technological failures and cyber-attacks. These incidents emphasize the need for a self-reliant and robust PNT ecosystem capable of withstanding both unintentional and malicious disruptions.
FrontierSI aims to bolster PNT resilience by enhancing the systems’ robustness against disruptions and advocating for the development of assured, robust, augmented and alternative PNT solutions. The recommendations outlined in the white paper and technical report call for proactive measures, including legislative updates and supply chain risk assessments, to protect Australia’s critical infrastructure and economic vitality.
