Drone mystery lights up Colorado skies

A proposed FAA rule — open for public comment until March 2 — would require drones over 0.55 pounds to electronically transmit their location and ID.

Northeastern Colorado was visited with a mystery in late December and January. Residents began seeing drones from 7 to 10 p.m. each night, moving in groups as large as 30, and flying in a grid pattern. The drones stayed about 200 feet to 300 feet in the air and flew steadily in squares of about 25 miles, at speeds estimated at 25–40 mph.

Reports were so numerous that a multi-agency task force was formed to investigate, including 10–15 law enforcement agencies as well as the FBI and Federal Aviation Administration (FAA). The drones were reported to measure six feet across and sound like a small jet engine. “These are not drones that people in our county can just buy,” said Washington County Sheriff Jon Stivers.

Numerous government agencies and companies denied the drones were theirs, including the U.S. Air Force, NOAA, NORAD, the FAA, and large drone developers Google, Amazon and Uber.

The Colorado Division of Fire Prevention and Control (DFPC) flew the state’s Multi-Mission Aircraft in an area where drones had been reported during two January missions.

Some suspect the drones were part of a secretive Air Force counter-drone program to protect nuclear missile silos. Another theory was a hunt for a missing nuclear warhead from one of the many intercontinental ballistic missile sites that dot the prairies of Wyoming, Colorado and Nebraska.

A group of Wichita, Kansas, drone enthusiasts also came forward, saying they had flown groups of drones in the area — but not to the same scale.

In an interview at January’s World Economic Forum in Davos, Switzerland, Transportation Secretary Elaine Chao told Yahoo Finance, “We don’t know who they belong to, we don’t know who’s operating them, to this day we do not.” Her department oversees the FAA, which issues Part 107 waivers to drone operators, allowing them to fly at night or out of line of sight of the operator. The waivers (thousands have been issued) lack enough specifics to narrow down who might be responsible for mystery drones.

A proposed FAA rule — open for public comment until March 2 — would require drones over 0.55 pounds to electronically transmit their location and ID, giving agencies access to information on drones in flight.

The new remote ID requirement would help with the creation of the Unmanned Aircraft System Traffic Management System, a project between the FAA, NASA and other agencies to “ultimately identify services, roles and responsibilities, information architecture, data exchange protocols, software functions, infrastructure, and performance requirements for enabling the management of low-altitude uncontrolled drone operations,” according to the FAA.

As of press time, no one has come forward to claim ownership of the drones. The public is encouraged to submit reports. As The X-Files’ Fox Mulder might say, “Watch the skies.”

Lay of the GNSS Land

Top receiver manufacturers discuss what’s on the horizon for GNSS receivers. The companies reveal recent and upcoming innovations, how to combat spoofing and jamming, fusing GNSS with other sensors, and the impact of increasing accuracy both for professional surveyors and consumers.

With regard to jamming and spoofing, the preferred approach is a combination of monitoring, detection and filtering. However, shielding, the use of IMUs and other third-party sensors, and advances in processing algorithms also help mitigate interference. In a few years, hopefully, encrypted or “watermarked” signals will substantially reduce this problem.

IMUs and other sensors are now routinely integrated with GNSS receivers, with their outputs fused. This trend is largely propelled on the demand side by the needs of the emerging market for autonomous vehicles and on the supply side by smaller, cheaper and more accurate IMUs and lidar scanners. Meanwhile, developments in algorithms have improved the modeling of errors to correct for the inherent tendency of IMUs to drift. Additionally, digital cameras, lidar and other industry-specific sensors are increasingly common, especially for collision avoidance in human-machine interactions.

In surveying, the use of all constellations and frequencies, as they become available, is an industry trend. Costs will continue to drop as the growth in the adoption of GNSS solutions enables manufacturers to take greater advantage of economies of scale. Precise point positioning (PPP), which benefits greatly from the growth in GNSS constellations, is now giving real-time kinematic (RTK) positioning a run for its money. Available applications enable Android mobile devices to achieve centimeter accuracy, while innovations continue in core positioning algorithms.

In the world of mobile consumer devices, dual-frequency, multi-constellation GNSS chipsets are increasingly prevalent. As increased accuracy fuels expectations for even higher accuracy, precision positioning may become the norm in the consumer space, and new applications for these devices may emerge. Already, crowdsourcing the monitoring of both GNSS signals and interference helps improve accuracy for everyone, in a positive feedback loop.

Other notable trends include the introduction and expansion of 5G data networks, the increased use of satellite-based correction services, and continued efforts to develop precise positioning for indoor areas.

Jamming and Spoofing. “We continue to develop and deploy patented technology to detect spoofing,” said Alok Srivastava, director, product management. “We already have cutting edge GNSS antenna technology to provide stellar support for interference rejection and filtering.” All Topcon end products have this advanced antenna and filtering technology.

Sensor Fusion. “Topcon has been using inertial systems for decades for a variety of positioning applications — such as machine control, mobile mapping, and agriculture,” said Srivastava. “In recent years, advancements in IMU technology have progressed to where the size and cost of these sensors are at levels to be utilized at a larger scale. For example, the recently released Topcon HiPer VR takes advantage of inertial technology to improve productivity in real time with our Topcon Integrated Leveling Technology (TILT), which compensates for mis-leveled field measurements out of plumb by as much as 15 degrees.”

Surveying. Topcon continues to invest in its core positioning algorithms to innovate such features as quartz lock loop, advanced multi-engine platform, and VHD heading technology into its positioning engines, Srivastava said. “We also produce solutions such as our Millimeter GPS and Hybrid Positioning innovations, which are designed around improving accuracy, higher reliability, and greater flexibility by converging positioning technologies.”

Consumer Devices. “GNSS in consumer devices and other commercial systems is used to aid other positioning sensors,” Srivastava said. “So, it may not be in the best of interest to offer that level of accuracy from GNSS alone.”

Other Challenges. Precise indoor positioning is a requirement of the vertical construction industry. “Topcon’s combined optical instrument takes a unique approach to solve that problem by integrating a compact laser scanner with a fully featured robotic total station,” Srivastava said.

Jamming and Spoofing. CHCNav is currently taking a twofold approach to GNSS interference, said François Martin, vice general manager, International Division. “As a GNSS system integrator, we focus our design around strong electromagnetic shielding and sealed isolation chambers.” Additionally, he pointed out, the advanced filtering of GNSS signals and an antenna patch produce optimal interference mitigation.

Sensor Fusion. Integrating interference-free, high-dynamic IMUs instead of MEMS has brought the full benefits of tilt compensation to users, Martin said. The latest development in algorithms dramatically obviated the need for the annoying process of initializing GNSS IMU receivers and boosted the availability of GNSS RTK in demanding environments.

Surveying. The fast adoption of GNSS solutions by large user segments has reduced costs by enabling a sizable manufacturing economy of scale, Martin pointed out. “Tighter combination of embedded technologies such as GNSS and connectivity modules are sustaining that cost reduction process.”

Consumer Devices. “The emergence of dual frequency multi-constellation GNSS chipsets supports the development of untapped user segments, but the position accuracy repeatability remains an issue,” Martin said. “The integration of GNSS chipset and high-performance helical antennas, as precision add-on modules, onto rugged Android cell phone and tablets is creating a prosumer-grade centimeter to decimeter accuracy answering to a wide range of mobile workforce applications.”

Other Challenges. A growing number of positioning and navigation applications require the fusion of technologies to increase productivity, Martin said. “The integration of advanced tightly integrated positioning algorithms, scanners, IMUs, HDR cameras, IoT and cloud-based connected solutions are a clear trend.” However, their adoption by a large user base remains limited by their current price point.

Jamming and Spoofing. “Recent developments in receiver-antenna combinations maximize the benefits of anti-jamming techniques,” said Gustavo Lopez, market access manager. Third party sensors, such as IMUs, also help mitigate interference, he pointed out. “Septentrio’s advanced receiver technology such as AIM+, a standard feature on all the company’s products, bring not only real time monitoring but also jamming/spoofing mitigation. Galileo and GPS have clear roadmaps bringing signal authentication in order to avoid spoofing.”

Sensor Fusion. Smaller IMUs with higher grade performance now on the market are enabling new use cases in autonomous applications, said Lopez. Other important elements are a new generation of compact high-performance sensors and the growing importance of multi-sensor technology “to provide even higher levels of positioning integrity.” He cited Septentrio’s AsteRx-i family of products as an example of GNSS/INS integrated solutions.

Surveying. As an example of Septentrio’s survey-specific products, which “continuously benefit from advanced developments being rolled out in our platform,” Lopez cited the Altus NR3.

Consumer Devices. The increasing positioning accuracy of cell phones, Lopez pointed out, “has spurred innovations such as PPP and the use of mobile phone measurements,” as well as “other purposes, such as interference detection and crowdsourcing.”

Other Challenges. “Sensor fusion is a key element in positioning and orientation,” Lopez said. “Easy integration is a key element in this trend. Also, integrity in error reporting and positioning will be required as well as reliable raw measurements which can be integrated with other sensors. This drives the requirement for receivers capable of running customer proprietary software. Another important element will also be the possibility of running positioning algorithms on a third-party processor.”

Hemisphere GNSS

Jamming and Spoofing. “Hemisphere’s new Lyra II ASIC platform used in our Phantom and Vega series positioning and heading boards,” said Miles Ware, director of marketing, “introduces new technology and filtering methods to identify and mitigate known and unknown interference sources that typically have an adverse effect on GNSS performance.”

Sensor Fusion. “Advancements in IMU integration and sensor fusion,” Ware said, “will continue to be a key focus for Hemisphere to support the growth and adoption of the expanding autonomous vehicle and application marketplace. The positioning and heading technology offered in our Vega 28 will be a core component for autonomous marine, machine control, and agriculture solutions for new and emerging markets.”

Surveying. “Access to modern and future signals like BeiDou Phase III, ALTBOC and BS-ACEBOC significantly enhance GNSS accuracy, especially in challenging environments where satellite visibility is compromised by the topography and or the structures present,” Ware pointed out. “Survey solutions that can not only track but also use all the available GNSS measurements in their RTK solution will have a substantial advantage in the market.”

Consumer Devices. “As mobile phones and consumer devices continue to adopt hardware designs that can access the latest GNSS signals,” Ware said, “the opportunities for solutions where high precision measurement engines can be hosted within mobile devices opens up a new realm of solutions that can leverage the high accuracy positioning performance found in Hemisphere technology and products. We see this as a very exciting and emerging area.”

Other Challenges. Ware pointed to “leveraging GNSS technology to further support environmentally friendly transportation solutions and sustainable agriculture,” for which GNSS continues to be an integral component.

Unicore Communications

Sensor Fusion. “We are implementing GNSS with different level IMUs, including low-cost and high-end, targeting automotive, intelligent driving, and robot application scenarios,” said Gao Jingbo, marketing director. “The algorithm can also integrate with the already-existing sensors on the platform, such as IMUs, cameras and odometers. The solution can be done on the GNSS side, with high information synchronization accuracy, or processed on the platform.”

Surveying. Products with Unicore boards inside can provide centimeter- to millimeter-level positioning accuracy, said Jingbo. “Unicore’s high precision boards and modules can track all frequencies of all satellite systems. The UGypsophila RTK technology can make the most of the observation data of all frequencies in all systems even without the observations of the base station in the RTK solution, thus greatly improving the usability, reliability and accuracy of RTK.” The company is now also working to reduce the dimensions and cost of its products, Jingbo pointed out. “With Unicore’s single GNSS SoC on board, the UB4B0M and UM4B0 modules are making affordable high-end high precision surveying possible.”

Consumer Devices. Algorithms and hardware are ready now to implement PPP+RTK in cell phones, Jingbo said, and this increase in positioning accuracy will enable many more applications. “We have rich experience in high precision GNSS, but the antenna might be a challenge. Our new generation 22 nm GNSS SoC features low power consumption and support of sensor fusion. Additionally, true point technology by Rx-Networks (also a BDStar company) can provide sub-meter data service, which also enables users to access centimeter-level accuracy location data through their mobile phones and wearable technologies, without increasing the demand for processing power.”

Trimble

Jamming and Spoofing. “Trimble’s latest GNSS receivers leverage our seventh-generation Maxwell technology, which implements hardware- and software-based techniques to detect and mitigate spoofing,” said Stuart Riley, vice president, GNSS Technology. “In addition, Trimble continues to improve the robustness of our GNSS receivers with advances in processing algorithms and hardware enhancements such as the integration of inertial technology.”

Sensor Fusion. “For many years, IMUs have been widely used in Trimble agriculture and Applanix products,” Riley said. “Over the past few years, we’ve created a new line of lower-cost inertially integrated board-level GNSS receivers. We have also integrated inertial components into survey and construction products, including tilt compensation in the Trimble R10, R12 and SPS986 receivers. Trimble also combines its GNSS solutions with optical, laser, lidar and other sensors.”

Surveying. Trimble’s GNSS products, Riley pointed out, range from GIS handhelds to high-performance mobile mapping systems.

Consumer Devices. “The Trimble Catalyst system uses Android-based smartphones or tablets to run an application that includes a software-defined GNSS receiver,” Riley said. “The recently introduced SiteVision system builds on this ecosystem and integrates Google’s ARCore platform with precision GNSS to provide an augmented reality solution for a variety of professional applications.”

Other Challenges. To address signal masking and multipath, Trimble has “continued to improve performance in difficult environments with products such as the Trimble R12 receiver, which provides sophisticated multipath mitigation and an advanced precision processing engine.” Riley said, “Trimble’s RTX Correction Services, delivered via satellite, enable users to achieve RTK speed and accuracy nearly anywhere on the planet without the need for local reference stations.”

Jamming and Spoofing. “The RF environment is at best crowded and at worst hostile,” said Sandy Kennedy, vice president of innovation, Hexagon’s Positioning Intelligence division. “The NovAtel OEM7 generation of receivers was launched in 2016, with interference detection and mitigation as key features on every variant. Protecting authenticity, availability, and precision for multifrequency measurements is the challenge going forward — in all segments of the system: constellation management and SIS, antenna, receiver design and processing in FW/SW.”

Sensor Fusion. In the last three years, Kennedy pointed out, IMU manufacturers have made significant improvements in the performance offered in smaller, cheaper IMUs. “At the same time, new methods to improve error modelling (to control positioning errors) have been added to the NovAtel SPAN product line, especially in SPAN Land profile. Extended GNSS outages are easily handled now.”

Surveying. “PPP has become a strong competitor to RTK, as convergence times have decreased, and this will continue in service offerings like Terrastar-X from NovAtel,” Kennedy said.

Consumer Devices. The devices, Kennedy said, offer “the tantalizing promise of quality measurements from a common utility device with huge computing horsepower and data connectivity built in! It’s fun to watch, and we shall see if accuracy is truly addictive enough to fuel development for general use of precision positioning.”

Other Challenges. “In the past 20 years, users have moved from awe and wonder that centimeter-level positioning is possible — to utter contempt when it is not,” Kennedy said. “This will continue, with an added requirement of integrity and functional safety. Continuously available positioning within a usable protection level is a requirement for autonomous vehicles.”

Look for part 2 in our February issue.

Automated shipping moves containers with Locata

At ION GNSS+ in September, I met with Nunzio Gambale and Paul Benshoeff of Locata. They were excited to share their news about the timing tests conducted at White Sands Missile Range by the U.S. Air Force’s 746th Test Squadron.

In the January issue, we share the results of the tests. The two also showed me and Matteo Luccio, our contributing editor, a YouTube video highlighting another Locata project: guiding 100-ton robots around the Ports of Auckland, New Zealand.

The robots are straddle carriers, giant mechanisms that are usually driven by a human. The carriers move and sort the shipping containers as they arrive from ships and leave via truck or train.

In the new setup, Locata has made possible the elimination of the human element with nanosecond-precision tracking.

Tom Scott, a former Sky One television host and now host of a series of YouTube shows, highlighted the robotic system in April 2019 on his “Amazing Places” channel.

Compared to manned straddle carriers, the automated straddle carriers (A-STRADs) are able to stack the containers closer, higher and work more steadily, increasing the capacity of the limited land space at the port. The A-STRADs can stack containers with the accuracy of a few centimeters.

The automated system also allows stack shuffling, so that wear and tear on the asphalt is spread more evenly and requires fewer repairs.

The Locata local positioning system uses synchronized transmitters installed around the port, with two antennas on each straddle carrier using the lightspeed delay from each transmitter to find exact position. “They don’t just look at the timing signal itself, they track the phase of each transmitter’s carrier signal,” Scott explained.

ISS-Reshetnev Company — the primary GLONASS contractor — has a backlog of orders for navigation satellites up to 2025, according to General Director Nikolay Testoyedov.

Testoyedov discussed GLONASS production on Dec. 30, 2019, at a meeting hosted by ISS-Reshetnev Company for Russia’s Science and Technical Council.

“Within the Federal Target Program, GLONASS ISS-Reshetnev Company is tasked with the production of 27 navigation satellites,” Testoyedov said. “Taking all things together, we plan to double the number of satellites launched in 2020 compared to 2019.”

The orders require production at full capacity at the company’s facilities. At any given time, about 50 satellites are in varying stages of production, including 12 ground spares. Some of them are slated for launch in 2020.

In 2019 eight satellites designed and built by the company were launched into various orbits. As of today,  104 ISS-Reshetnev-made satellites are in space, or two-thirds of Russia’s entire orbital fleet of satellites. ISS-Reshetnev also successfully completed several projects for the manufacture of satellite onboard systems and instruments, including the international ExoMars-2020 program slated to launch this year.

Glonass-M satellite goes into service

The Glonass-M navigation satellite launched on Dec. 11, 2019, entered service Jan. 13.

A joint team of experts representing ISS-Reshetnev Company and the operating organization successfully completed all procedures moving the Glonass-M satellite to its proper orbital position, and switched on its main instruments. To this date, all the required data has been received from the satellite, which allowed it to be commissioned into service.

The new Glonass-M replaced a retired satellite of the GLONASS constellation that had surpassed its designed life expectancy by seven years.

As University of Mississippi (UM) students resume classes for the spring semester, they are sharing the campus’ sidewalks with a fleet of robots that can deliver meals at the push of a button.

Starship Technologies has launched robot food delivery services at the university, the first in the Southeastern Conference to have autonomous delivery robots.

Beginning Jan. 22, Ole Miss students, faculty and staff can access the Starship Deliveries app (iOS and Android) to order food and drinks to be delivered anywhere on campus, within minutes from any of the 30 robots serving UM. The service will work in conjunction with student meal plans.

Ole Miss Dining is focused on the continued utilization of advanced technology to enrich the student, faculty and staff dining experience,” said Chip Burr, resident district manager of Ole Miss Dining Services. “We are excited about the expansion of our mobile ordering operation and the new opportunities this partnership creates.”

The robots use a combination of sophisticated machine learning, artificial intelligence and sensors to travel on sidewalks and navigate around obstacles. The computer vision-based navigation helps the robots to map their environment to the nearest inch. They can cross streets, climb curbs, travel at night and operate in both rain and snow.

A team of humans also can monitor their progress remotely and take control if needed.


By making food and drink more accessible, the Starship robots save time and reduce stress, aiming to make the busy lives of the Ole Miss community a little easier, Burr said.

Items can be ordered from Starbucks, Chick-fil-A, McAlister’s, Panda Express, Which Wich, Qdoba, Einstein Bros. Bagels, Raising Cane’s, Steak ‘n Shake, Freshii, Papa John’s and Sambazon. After choosing their items, users select their location by dropping a pin on the campus map where they want their food delivered.

The app allows users to watch the robot’s journey in real time through an interactive map. Once the robot arrives, the user will receive an alert and can meet the robot and unlock it through the app.

The delivery usually takes just minutes, depending on the menu items ordered and the distance the robot must travel. The robots can carry up to 20 pounds.

Starship Technologies operates commercially on a daily basis around the world. Its robots have traveled more than 350,000 miles and completed 100,000 autonomous deliveries.

“We’re honored to be able to help make lives a little bit easier for Rebels across the Ole Miss campus by offering the world’s leading autonomous delivery service” said Ryan Tuohy, senior vice president of business development at Starship. “Whether it’s getting breakfast delivered in the morning or having a late-night snack, our robots are here to serve students, faculty and staff at all times of the day.”

Audi, Qualcomm and Virginia DOT to deploy C-V2X

Audi of America, the Virginia Department of Transportation (VDOT) and Qualcomm Technologies Inc. are planning for initial deployments of cellular vehicle-to-everything (C-V2X) communication on northern Virginia roadways.

C-V2X employs advanced wireless communications to enhance vehicle safety by using the same portion of the 5.9-GHz band that the Federal Communications Commission (FCC) has proposed to allocate for C-V2X.

In line with the Federal Department of Transportation’s announcement to establish a First Responder Safety Pilot Program, the organizations’ combined efforts are designed to focus on improving safety for construction workers and motorists.

The initial deployment is expected to take place on select roadways in Virginia beginning in the third quarter of this year.

C-V2X will be used to deliver work zone warnings on highways as well as signal timing information on approaches to signalized intersections on arterial roadways. In both cases, C-V2X communications can help deliver critical safety messages between vehicles and infrastructure with minimal latency, while less time-sensitive alerts are designed to be provided via C-V2X using the cellular network.

The initial deployments are aimed at expanding safety use cases in the connected vehicle safety spectrum established by the FCC, with the aim to curtail road hazards and fatalities. In a given year, traffic fatalities in the U.S. exceed 36,000 people.

The initial deployment is designed for connected-car systems designed to

  • boost safety around school buses,
  • warn motorists about dangerous road conditions,
  • alleviate congestion at traffic chokepoints and curbsides,
  • help improve the performance of automated vehicles that are nearing commercialization
  • potentially let cars communicate with mobile devices to send warnings that may one day help prevent the more than 6,000 pedestrian fatalities per year.

The northern Virginia initial deployment involves two primary use cases:

  • Work zone warnings, which the organizations feel is an important use case on highways, featuring a Qualcomm 9150 C-V2X chipset solution via an in-vehicle display in Audi Q8 SUVs designed to deliver a graduated warning, with the last link being a low-latency, reliable warning to drivers of the workers’ physical presence.
  • On arterial roadways, the signal phase and timing (SpaT) from a traffic signal, will be transmitted with a Qualcomm 9150 C-V2X chipset solution to Audi Q8 SUVs. These vehicles have the Audi Traffic Light Information (TLI) service that can provide drivers a countdown to the green light. C-V2X from the traffic signal can also provide direct information to the Audi Q8, which will be used by the TLI system to fine-tune the countdown information of the signal phase and timing.

“VDOT has long supported research into the benefits of connected and automated vehicles, particularly those aspects that have the potential to significantly enhance safety,” said Virginia’s Director of Transportation Research and Innovation Cathy McGhee. “The inclusion of shorter-range, direct communication in the 5.9 GHz band using C-V2X is exciting, as it can allow us to evaluate this emerging communication option for essential and practical safety and mobility services, including saving the lives of maintenance and construction personnel in work zones.”

“We recognize the immediate value of the spectrum that the FCC proposed to allocate to C-V2X, and we endeavor to show our V2X equipped cars on real roads engaging in how transportation safety and mobility could be jump-started,” said Anupam Malhotra, Director, Connected Vehicle Services, Audi of America. “We are excited about our participation in this pilot deployment as it highlights the broad societal advantages that technology is now poised to deliver through the full 5.9 GHz V2X spectrum near term with far, far more to come as connected and automated vehicle fleets emerge over the next decade.”

Audi’s Traffic Light Information V2X services operate in 25 cities and nearly 10,000 intersections nationwide, including more than 1,700 intersections in the Washington D.C. metropolitan region.

“Qualcomm Technologies is excited to work with the VDOT, through its partner Virginia Tech and Audi to support the C-V2X use cases on the very same spectrum that the FCC has proposed to allocate for C-V2X. Qualcomm Technologies has long been a pioneer in the connected car with over 20 years of experience delivering in-vehicle telematic systems,” said Jim Misener, senior director, product management, Qualcomm Technologies, Inc. “With the advances in cellular communications now enabling us to also offer direct connectivity for safety services, traffic efficiency and emerging automated use cases, we are pleased to work closely with VDOT, Audi of America and Virginia Tech to showcase the commercial maturity and technological sophistication of C-V2X and to start the proliferation of the technology on U.S. roadways.”

The Virginia Tech Transportation Institute (VTTI) will develop the software and systems to support the primary use cases defined for the initial deployment. Following software development, the institute will then conduct a demonstration of C-V2X technology operating in these use cases.

C-V2X Features and Benefits

  • The C-V2X solution used in this initial deployment is based on third-generation partnership project (3GPP) Release 14 and Release 15 specifications. Direct communication of this solution uses 20 MHz from the 5.905 – 5.925 GHz ITS band, the same spectrum that the FCC has proposed allocating for C-V2X.
  • A more advanced mode of C-V2X has an evolution path to 5G using 3GPP Release 16 specifications.
    Field test results issued by the 5G Automotive Association (5GAA) have proven C-V2X to be an efficient and effective radio access technology, showing that it significantly increases in range and reliability compared to other radio technologies.
  • C-V2X commercial products are now widely available in the form of multiple chip platforms, wireless modules, vehicular Onboard Units and infrastructure Roadside Units.
  • C-V2X encompasses both direct short-range communications that operate in the 5.9GHz ITS band and longer-range network communications delivered by mobile network operators; chipsets now offer both direct and network connectivity in the same solution concurrently, aiding in the adoption of the technology.

Public Service Announcement: Update to the latest point release now

QGIS users who have adopted the 3.10 version when initially released at the end of October 2019 have likely noticed a sharp drop in reliability. The underlying issues have now been addressed in 3.10.2, all users are advised to update *now*.

When QGIS 3.10 was first released in the end of October 2019, a pair of libraries – namely GDAL and PROJ – were updated to their next-generation versions. The advantages are plenty: GeoPDF export[1] support, more accurate coordinate transformation, etc. For those interested, more technical information on this is available here[2].

The update of these crucial libraries led to a number of regressions. While we expected some issues to arise, the seriousness of the disruption caught us off guard. Yet, it was also somewhat inevitable: QGIS is the first large GIS project to expose these next-generation libraries to the masses. The large number of QGIS users across the globe were essentially stress testing both new code within QGIS as well as the libraries themselves.

Thanks to dedicated users taking time to file in report and the community helping out as well as our project sponsors for allowing us to fund development time, developers have been able to fix all known regressions in both in QGIS as well as underlying GDAL and PROJ libraries, benefiting a large number of open source projects.

As a result of this collective effort by the community, QGIS 3.10.2 is now back to being the reliable and stable GIS software we all love. As such, we cannot stress enough the importance of updating now.

Once again, thanks to our community of testers, sponsors, and developers for their countless hours and efforts in making QGIS better.

Happy mapping!
