The European Union PAVE-SCAN project aims to build European GNSS-based and AI-driven technologies to detect and assess roadway pavement problems.
The proposed project aims for the development to market (TRL8-9) of European GNSS-based integrated low-cost sensor technologies and artificial-intelligence-driven open-architecture software solution — machine learning (ML) and machine vision (MV) — for the detection, classification and georeferencing of roadway pavement surface anomalies, and for the low-cost assessment of roadway pavements using participatory sensing.
The proposed system is of practical importance because it provides continuous information about roadway pavement surface anomalies — valuable for efficiently monitoring the transport infrastructure and for public safety. The vision for roadway condition assessment using smartphone-like technology is under the hypothesis that such technology can be used for crowd-sourced data collection and analysis in GIS-based pavement management systems (PMS).
“The developed technology and related transport informatics are disruptive technologies that have the potential to reshape the transport and infrastructure industries,” according to the project description.

Product to market and ‘Product as a Service’ (PaaS) business model
Position Partners has unveiled SmartSurveyor, which facilitates accurate, survey-grade aerial mapping and photogrammetry without the need for a connection between a camera shutter and a GNSS receiver.
The fully compact, handheld, aerial mapping survey rover is compatible with DJI Mavix 2 and 3 series and Phantom 4 Pro drones.

The design is dissimilar to other drone mapping systems in that it works from a drone or smartphone and with two or more ground control points (GCPs) while using an ultra-matching technique.
Once data is captured by SmartSurveyor, all the photos and the GNSS file are uploaded to a PC and analyzed through the Agisoft UltraMatch workflow to confirm their accuracy before they are exported. Data can be managed in the cloud or on a local PC using software designed by MapSender.
Additionally, this mapping tool works in tandem with the AllDayRTK subscription GNSS network service so collected data can be uploaded to Tokara to remotely manage a project.
What is the most promising approach to increasing the location accuracy of smartphones?
Ismael Colomina
“In addition to the use of increasingly available augmentation services, such as Galileo’s free High-Accuracy Service (HAS), I see two development directions that may help, particularly in the context of positioning in urban areas where smartphones are most used. One is the use of 3D city models — in general, 3D geoinformation — to compensate for multipath, non-line-of-sight and occlusion effects. The other is to use signals that are robust against those effects, which today are only available in geodetic-grade receivers.” — Ismael Colomina, GeoNumerics
For the navigation of autonomous vehicles, will GNSS become essential, or will it be relegated to a secondary role by robotic navigation methods?
John Fischer
“The PNT solution cannot be from a single source because autonomous navigation requires high integrity. Therefore, it’s not that GNSS will be relegated to secondary status, it’s that no one method will be primary. An intelligent fusion of diverse sensors —including GNSS — will provide the PNT solution along with an integrity metric that safeguards operation. The various sensors must agree. If they don’t, no trust can be put into the solution and autonomous navigation will cease. The definition of a new integrity metric that quantifies this trust level is needed.” — John Fischer, Orolia
Ellen Hall
“Because GNSS provides high precision and widely available PNT, it will continue to be a critical component in navigation while working with computer vision, inertial measurement units (IMUs) and lidar through sensor fusion. As a secondary component, GNSS serves a vital role for localization and validation.” — Ellen Hall, Spirent Federal Systems
Tbe company has received Global Certification Forum validation of 5G LBS Assisted-Galileo test case
Keysight Technologies Inc. has gained Global Certification Forum (GCF) validation of a 5G location-based services (LBS) assisted-Galileo (A-Galileo) test case by combining 5G new radio (NR) and GNSS technology.
The achievement will accelerate implementation of LBS in smartphones by enabling mobile phone vendors to verify that designs comply to the latest 3GPP specifications that support accurate location positioning in a wide range of sectors.
Sectors include healthcare, road and aerial transportation, emergency and rescue services, public safety, and homeland security. Highly precise positioning services also enable mobile operators to deliver personalized services supporting entertainment, hospitality and retail applications.
LBS leverages different technologies, including GNSS, beamforming and round-trip time to geographically locate a user. LBS test cases allow users to verify sensitivity, accuracy and dynamic range in mobile phones that leverage GNSS constellations to identify precise geographic location.

GCF conformance agreement group meeting #72, held Oct. 21, confirmed the validation of the first 5G LBS A-Galileo test case, which was supported by Keysight’s S8705A RF/RRM DVT and Conformance Toolset. The toolset provides access to a wide range of radio frequency, radio resource management, and development validation test cases used to verify 5G NR designs in both non-standalone and standalone deployment modes.
The S8705A toolset uses the E7515B UXM 5G Wireless Test Platform, a compact signaling test platform with multi-format stack support, rich processing power and abundant RF resources for emulating various mobility scenarios in a 5G network as well as a recommended GNSS emulator to deliver the LBS test case.
The Indian government is pushing smartphone makers to sell devices that receive NavIC signals along with GPS.
India originally stated NavIC would be required in smartphones sold starting in January 2023, according to Reuters, but strong reaction from smartphone manufacturers Apple, Xiaomi and Samsung apparently caused the government to push back or remove the deadline.
A deadline of January 2023 would not allow enough time for smartphone makers to integrate NavIC-enabled receivers to their devices. Steps include redesign, securing parts, testing and assembly. Many smartphones sold in India by the companies are economy-level devices priced under US$200.
The three tech giants met with government officials, seeking an extended target date of 2025, Reuters reported.
However, India’s Ministry of Electronics & IT issued a statement via Twitter :
A media report has claimed citing a meeting that mobile cos were asked to make smartphones compatible with NavIC within months. This is to clarify: (1) No timeline has been fixed. (2) The cited meeting was consultative; and (3) the issue is under discussion with all stakeholders.
NavIC (Navigation with Indian Constellation) is the operational name for the Indian Regional Navigation Satellite System (IRNSS) developed by India’s space agency for military and commercial purposes. NavIC consists of eight satellites that cover the Indian mainland and the region extending up to 1,500 km from its boundaries.
“NavIC can help in navigation on land, air, sea and also in disaster management,” Science & Technology Minister Jitendra Singh said in a press release. “NavIC satellites are placed at a higher orbit than the GPS of United States. NavIC satellites are placed in geostationary orbit (GEO) and geosynchronous orbit (GSO) with an altitude of about 36,000 km; GPS satellites are placed in medium earth orbit (MEO) with an altitude of about 20,000 km.”
“NavIC uses dual-frequency bands, which improves accuracy of dual-frequency receivers by enabling them to correct atmospheric errors through simultaneous use of two frequencies,” Singh said. “It also helps in better reliability and availability because the signal from either frequency can serve the positioning requirement equally well.”

Citizens Clean Up Coasts
Two citizen groups are taking action with the help of Esri ArcGIS mapping tools. North Coast World Earth uses Esri Ireland’s platform on the Northern Irish coast to record litter hotspots and engage with local communities. The volunteer group has collected nearly 3 tons of litter. In California, the Surfrider Foundation employed ArcGIS Hub to streamline cleanup operations after a major oil spill off Huntington Beach in October 2021. Citizens submitted more than 1,100 reports using the ArcGIS QuickCapture photo app to share the date, time and coordinates of toxic tar balls on beaches from Oxnard to San Diego.
A new series of tests will assess whether the United Kingdom satellite-based augmentation system (UKSBAS) for GNSS can develop into full operational capability to support safety-critical applications post-Brexit. Inmarsat, Goonhilly Earth Station and GMV NSL are conducting the UK Space Agency-funded tests. The signal is now stable and operational, enabling ongoing testing and validation by industry, regulators and users. If successful, UKSBAS will enable assessment of more precise, resilient and high-integrity navigation for maritime and aviation users in UK waters and airspace.

Smart GNSS Monitoring
More than 11,000 people around Europe and the world have turned their smartphones into GNSS monitoring tools by downloading the CAMALIOT app, so far delivering more than 53 billion measurements of meteorology and space weather patterns to researchers, reports the European Space Agency (ESA). ESA asks CAMALIOT volunteers to leave their smartphones by a window each night with GNSS on. The phones record small variations in satellite signals, gathering data for machine-learning analysis. More than 50 smartphone models with dual-frequency receivers can use the app.
Indian Prime Minister Narendra Modi gave his stamp of approval to his country’s indigenous NavIC during a drone festival May 27. Despite that, the Indian Army purchased three GNSS receivers from Baidu, a Chinese company, instead of relying on home-grown companies as the contract required, reports The New Indian Express. The receivers are for survey stations of the College of Military Engineering. A few Indian manufacturers objected to the purchase, the newspaper said, but their concerns were brushed aside by the Department of Military Affairs.
Winners will present their projects at ION GNSS+ 2022 in Denver
The Institute of Navigation’s Satellite Division, in partnership with Google, will host the 2nd annual Smartphone Decimeter Challenge, with the winning teams presenting their methods at the ION GNSS+ 2022 meeting. ION GNSS+ 2022 takes place Sept. 19–23 at the Hyatt Regency Denver, adjacent to the Colorado Convention Centerx.
The Smartphone Decimeter Challenge is designed to advance research in smartphone GNSS positioning accuracy using state-of-the-art algorithms and technologies such as advanced machine learning models and precision GNSS algorithms.
While standard receivers using signals from GPS, other GNSS (Galileo, BeiDou, GLONASS) and regional systems (QZSS and IRNSS) provide accuracy between 3 and 10 meters (often worse in urban environments), better location can be obtained by processing carrier-phase measurements, inertial measurement unit (IMU) data, and base station corrections.
Teams will use datasets collected using the GPS receivers and IMUs of Android smartphones to compute location down to an accuracy of decimeters. Mobile users will benefit from lane-level-accuracy-based services, enhanced experience in location-based gaming, and greater specificity in location of road safety issues.
Winner selection is based on the accuracy of results from the test datasets compared to highly accurate ground truth. The top three winners will receive prizes valued at $15,000+ including a guaranteed speaking slot at the highly competitive ION GNSS+ 2022 conference (subject to technical paper and ION presentation requirements); a travel subsidy; and complimentary registration to attend ION GNSS+ 2022 in Denver.
A new Android app released by the European Space Agency (ESA) turns smartphones equipped with dual-frequency GNSS receivers into instruments for crowdsourced science.
The CAMALIOT app, developed through ESA’s Navigation Innovation and Support Programme (NAVISP) with the support of the GNSS Science Support Centre, is suitable for more than 50 smartphone models.
Using the CAMALIOT app, the phones will record small variations in satellite signals, gathering data for machine learning analysis of meteorology and space weather patterns.
As well as helping to create new Earth and space weather forecasting models, participants are also in with the chance to win prizes including new phones and Amazon vouchers. This four-month “citizen science” campaign runs until the end of July.
“The precisely modulated signals continuously generated by the dozens of GNSS satellites in orbit are proving a valuable resource for science, increasingly employed to study Earth’s atmosphere, oceans and surface environments,” said ESA navigation engineer Vicente Navarro. “Our GNSS Science Support Centre was created to help support this trend.”
For instance, tens of thousands of permanent GNSS stations are continuously recording GNSS data. As the satellite signals travel down to Earth they are modified by the amount of water vapor in the lower atmosphere, helping to forecast rainfall in particular.
GNSS signals also undergo delay and fading — known as scintillation — as they pass through irregular plasma patches in the ionosphere. This electrically charged upper atmospheric layer is continuously changing, influenced by solar activity, geomagnetic conditions and the local time of day. Dual-frequency GNSS receivers can compensate for this effect by comparing their two frequencies.
“The combination of Galileo dual band smartphone receivers and Android’s support for raw GNSS data recording is what opened up the prospect of supplementing data from these fixed GNSS stations with tens of millions of smartphones, vastly increasing our density of coverage,” Vincente said. “We took inspiration from the famous ‘SETI@home’ initiative, where home laptops help seek out signs of extraterrestrial life.”
The results can then undergo a Big Data machine learning approach, seeking out previously unseen patterns in both Earth and space weather.
“This is our first step in enlarging GNSS data acquisition using an internet of things data-fusion approach, employing novel sources such as fixed sensors and drones as well as smartphones,” Vincente said. “A wide range of other applications are also possible for the system, including improving the performance of GNSS systems.”
Formally known as the Application of Machine Learning Technology for GNSS IoT Data Fusion project, CAMALIOT is run by a consortium led by ETH Zurich (ETHZ) in collaboration with the International Institute for Applied Systems Analysis (IIASA).
“The CAMALIOT effort was underpinned by Element 1 of our NAVISP research programme, spurring innovation in satellite navigation,” said Pierluigi Mancini, ESA’s NAVISP program manager.
The PureL5 Customer Evaluation System is being tested by California and Chinese companies
OneNav has announced the commercial availability of its pureL5 GNSS digital IP core.
The pureL5 digital IP core’s architecture enables it to directly acquire and track L5 signals from GPS, Galileo, BeiDou, QZSS and GLONASS without any L1 aiding. This eliminates the entire L1 RF chain, saves space on the printed circuit board, and simplifies the RF front-end and antenna subsystem in smartphones, wearables and trackers.
The pureL5 digital IP core’s massively parallel array processor searches the entire 1-millisecond L5 code space in parallel, delivering 1 second time to first fix (TTFF). The pureL5 digital IP core is 0.28mm2 in the 3-nm semiconductor process and consumes 4.7 mW of power in 1-Hz tracking mode.
OneNav has delivered the pureL5 digital IP core register-transfer level (RTL) to its first system-on-chip (SOC) customer. IP core RTL verification and physical implementation are complete, and oneNav’s SOC licensee will tape out in the first quarter of this year. The pureL5 digital IP core RTL is available for customer licensing and shipment now.
Customer Evaluation System. OneNav’s pureL5 Customer Evaluation System is being tested by companies in California and China. The system is available for smartphone and wearable OEMs and SOC providers who want to evaluate oneNav’s pureL5 in the field and the lab.

Galileo-supported E112 will result in faster response times and more lives saved. (Image: EUSPA)
As of March 17, all smartphones sold in the European Union must be leveraging Galileo signals in addition to other GNSS for calls to the European 112 (E112) emergency number.
Using Galileo enhances pinpointing locations of 112 calls in Europe, resulting in faster response times and more lives saved, according to the EU Agency for the Space Programme (EUSPA).
The 112 emergency number is operational in nearly all EU Member States, as well as other countries. People in danger can call it 24/7 to reach the fire brigade, medical assistance and the police.
Most calls to the 112 emergency number are placed from mobile phones. These calls already support the sending of location information to emergency services. However, this information was not based on GNSS capabilities until recently.
Three years ago, the Commission Delegated Regulation anticipated measures to take advantage of GNSS and Wi-Fi location capabilities in smartphones placed on the European Union market, starting March 17.
GNSS versus cell-ID
Until now, the 112 caller’s location information was established through identification technology based on the coverage area of a cellular network tower (cell-ID). The average accuracy of this information varies from two to 10 kilometers, which can lead to significant search errors following emergency calls.
By contrast, GNSS location information pinpoints the call within a few meters. This level of accuracy will have a major impact in terms of response times, ultimately allowing for quicker intervention in emergency situations.
Galileo 112 rollout
The ability for 112 to communicate a caller’s location to emergency services automatically is already being rolled out. The protocol — Advanced Mobile Location (AML) — is being deployed across the European Union. When a caller dials 112 from their smartphone, AML uses the phone’s integrated functionalities and data from Galileo to accurately pinpoint the caller’s location and transmit it to a dedicated endpoint, usually a Public Safety Answering Point (PSAP), which makes the caller location available to emergency responders in real time.
According to the European Emergency Number Association (EENA), at least 18 EU Member States have already completed AML deployment, while others are in the process of doing so. This implementation is because of EU initiatives and projects such as the Help 112 project, which was set up to evaluate the merits of handset-based technologies in improving the location of emergency callers.

Construction of the BeiDou Navigation Satellite System (BDS-3) has been completed. The system was formally commissioned on July 31, 2020. In 2021, BDS continued to improve performance, expand applications and deepen cooperation, and has achieved sustained, stable and rapid development.
System Performance and Services
Currently, 45 BDS satellites are operational in orbit — 15 BDS-2 satellites and 30 BDS-3 satellites jointly provide seven types of services to users. Specifically, for the entire planet, the system provides three services:
Positioning, navigation and timing (PNT).
Global short-message communication.
International search-and-rescue (SAR) services.
For the Asia-Pacific region, the system provides four additional services:
Satellite-based augmentation.
Ground-based augmentation.
Precise point positioning.
Regional short-message communication services.
The system has been operating continuously and stably since commissioning, with the average value of satellite availability better than 0.99 and the average value of satellite continuity better than 0.999.
PNT Service. As actually measured by the International GNSS Monitoring and Assessment System (iGMAS), the global horizontal positioning accuracy is about 1.52 meters, the vertical positioning accuracy is about 2.64 meters (B1C signal single frequency, 95% confidence), the velocity measurement accuracy is better than 0.1 m/s, and timing accuracy is better than 20 nanoseconds. The performance is better in the Asia-Pacific region.

Global Short Message Communication Service. Trial service is provided through 14 medium-Earth-orbit (MEO) satellites for authorized users and low-orbit satellites, with a maximum single-message length of 560 bits, equivalent to about 40 Chinese characters.
Search-and-Rescue Service. A COSPAS/SARSAT-compliant MEOSAR service is provided by six payloads deployed on six MEO satellites. A B2b signal-based Return Link Service (RLS) is provided through 24 MEO and three IGSO satellites, which have completed testing and verification and are in the process of coordination within the framework of COSPAS-SARSAT.
Satellite-Based Augmentation Service. China’s Civil Aviation Administration is organizing satellite-ground integrated test and evaluation, and the positioning accuracy, alarm time, integrity risk and other indicators meet the requirements.
Ground-Based Augmentation Service. Real-time centimeter-level and post-processing millimeter-level services are provided for industrial and public users, based on the regional network reference stations built in China.
Precise Point Positioning Service. PPP signals are broadcast by three GEO satellites. The measured horizontal positioning accuracy is 0.24 m, the vertical positioning accuracy is 0.41 m (95% confidence), and the convergence time is less than 20 minutes.
Regional Short Message Communication Service. The short-message communication function has been tested and verified for integration into public mobile phones; large-scale application is planned.
Development of the Applications Industry
Large-scale applications of BDS have entered a critical stage of liberalization, industrialization and internationalization. The overall output value of China’s satellite navigation and location-based service industry continued to grow in 2020, up to 403.3 billion yuan (US$63.2 billion), which is about 16.9% more than its value in 2019. In terms of BDS-3-enabled basic products, an industrial chain is gradually maturing, comprised of BDS/GNSS basic chips, modules, boards, antennas and other components.
The certification and testing system of basic BDS products has been established and implemented. BDS is already supported by most mainstream chips. BDS is increasingly being integrated into the daily life of the general public. It is becoming the standard configuration for positioning functions of smartphones and other mass-market products.
Smartphone manufacturers such as Xiaomi, Huawei, Apple and Samsung already support BDS. In the first three quarters of 2021, among all types of smartphones applying for online access in China, 72.3% supported positioning function based on BDS, accounting for 93.5% of the total sales volume. The BDS ground-based augmentation function has been introduced into smartphones to achieve high-precision positioning at the 1-meter level; lane-level navigation is being piloted in several cities in China.
In terms of industrial applications, BDS has fully served multiple industries including transportation, public security, disaster relief, agriculture, forestry, animal husbandry and fishing. It has accelerated the integration into electricity, finance, communications and other infrastructure. In particular, in the fight against COVID-19 through scientific and technological approaches, BDS-based precise positioning has facilitated the efficient supply and circulation of anti-epidemic materials.
BDS-based solutions for land rights determination, precision agriculture and smart ports have served the economic and social development of countries in Asia, Eastern Europe and Africa, and BDS-based products have been applied in more than half of the world’s countries and regions.
International Cooperation
BDS has always adhered to the development concepts of openness, cooperation and resource sharing; actively carried out practical international exchanges and cooperation; and contributed to China’s peaceful use of outer space.
Bilaterally, the Eighth Meeting of the China-Russia Project Committee on Major Strategic Cooperation in Satellite Navigation was held in October 2021. Both sides jointly formulated and signed the Roadmap for Cooperation in the Field of Satellite Navigation from 2021 to 2025, providing planning and guidance for China-Russia satellite navigation cooperation in the next five years. Also, China’s Satellite Navigation Office signed a memorandum of understanding on satellite navigation cooperation with the National Committee on Space Activities of the Republic of Argentina and the South African National Space Agency, and formally established a regular cooperation mechanism.
BDS is gradually being integrated into international standards, and is steadily promoting ratification by international standards bodies, including in the civil aviation, maritime, SAR, mobile communications and electrotechnical fields. Several international standards supporting BDS have been released. The Chinese government has drafted a letter of commitment to the International Civil Aviation Organization (ICAO), stating that BDS will provide basic services free of charge to civil aviation users around the world. The International Association of Marine Aids to Navigation and Lighthouse Authorities (IALA) has officially issued a standard that ratifies BDSBAS, so that global marine users can carry out applications based on it. The Third Generation Partnership Project has started the standardization of BDS-3’s B2a and B3I signals. In the detection standard for Indicating Radio Beacon Locator of the Global Maritime Distress and Safety System issued by the International Electrotechnical Commission, BDS receivers and BDS-based SAR services will be supported.
The Chinese government is steadily advancing the rule of law, attaching great importance to and comprehensively promoting the rule of law for satellite navigation. A legal system on BDS has been formed, consisting of national policies, industrial and local policies and regulations, and more. The legislative process of the Satellite Navigation Regulations of the People’s Republic of China has been actively promoted to ensure the healthy, rapid and sustainable development of the satellite industry. In May 2021, China issued a development report on the rule of law of BDS.
Follow-Up Plan
In the future, on the one hand BDS will ensure stable operation, while on the other hand it will focus on the development of backup satellites, and complete the production, state optimization and ground testing of backup satellites. Backup BDS-3 satellites with better performance will be launched as needed to further improve the reliability of the constellation. By adhering to the development concept of “BDS is developed by China, dedicated to the world and aiming to be first class,” carrying forward the BDS spirit of the new era of “independent innovation, open integration, unity of all, pursuit of excellence,” BDS will serve the world and benefit all humankind.
Number of BDS-3 satellites in orbit: 30
Signals broadcast: B1I, B3I, B1C, B2a, and B2b
