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.

U-blox L-band receiver enables cm-level positioning for mass market

Photo: u-blox

U-blox said its new NEO-D9S GNSS correction data receiver module provides an affordable approach to bringing centimeter-level accuracy to GNSS receivers.

The NEO-D9S receives from correction service providers broadcast on the L-band (1525-1559 MHz). A host processor can then decrypt this correction data and provide it to a high-precision GNSS receiver, combining corrections directly with readings from the satellite constellations to enable much more accurate position readings than those offered by GNSS signals alone.

Use of the NEO-D9S will also increase the availability of high-precision GNSS positioning data in areas with limited connectivity and reduce the amount of cellular data consumed by positioning receivers.

Customers are expected to include carmakers, both Tier 1 and OEMs, industrial system integrators that offer position-correction services, and any other applications that rely on very accurate positioning at low cost.

The NEO-D9S module is a correction-only receiver, based on the latest u-blox ninth-generation (D9) platform. This means that it will integrate easily with the u-blox F9 RTK GNSS receivers from u-blox, or can be used as part of a modular product roadmap. The module also integrates a TCXO and SAW filter to ensure good RF sensitivity and resilience to interference from adjacent channels.

The module includes the algorithms necessary to decode satellite data broadcasts. It is configured to work initially with whichever correction service has been set as default, but can be configured for any L-band data broadcast. It stores its configuration settings in non-volatile memory.

Airbus reminds pilots what to do when GNSS interference hits

Airbus is providing safety information to all pilots, not just those of the new BelugaXL. (Photo: Airbus)

Commercial airline pilots should be ready if their GNSS interference or jamming takes place. This safety message, along with steps to take, was provided by Airbus in the January issue of its publication “Safety First.”

In the publication, Airbus is reminding pilots of the consequences and required action in the cockpit, according to Aviation Week. Loss of the GNSS signal can affect navigation and surveillance functions. While built-in redundancies will maintain position computation, up to a dozen systems and functions can be affected.

Cover: Airbus

“A loss of GNSS inputs does not lead to a map shift or an erroneous position computation by the FMS (Flight Management System). In the case of a loss of GPS signal, the FMS switches from the mixed GPS/IRS position to an IRS-DME/DME position or IRS-VOR/DME or pure IRS, in order of priority,” the experts explain in the publication.

Other affected systems can include the predictive functions of the terrain awareness and warning system, the runway overrun protection system, and ADS-B Out, in which case pilots should notify air traffic control.

Once the flight is over, pilots should report the GNSS interference event to air navigation service providers.

Research Roundup: Focus on maritime

The 18,000-container-capacity CMA CGM Kuergelen. (Photo: CMA CGM)

Of the 273 papers researchers presented this year at the Institute of Navigation’s annual ION GNSS+ conference, which took place in Miami on Sept. 16–20, the following five focused on maritime issues. Papers are available at www.ion.org/publications/browse.cfm.

Automating the Sharing of Ocean Weather Data

The Automatic Identification System (AIS) — mandatory for large ships and used by many mid-sized ones — was designed to help avoid collisions, enable shore authorities to provide vessel traffic services, and allow coastal states to monitor their waters. It also may be used to transmit other information between AIS stations onboard and ashore.

In the aftermath of the sinking of the container ship El Faro in 2015, the U.S. National Transportation Safety Board (NTSB) and U.S. Coast Guard found a contributing factor was lack of reliable weather forecasts. The NTSB then recommended to the National Oceanic and Atmospheric Administration (NOAA) that it determine whether AIS could be used to share weather data collected by ships, to supplement the Voluntary Observing Ship (VOS) program where ships voluntarily submit weather observations to NOAA. The paper describes a successful test of this concept.

Citation. Gregory Johnson, Ken Dykstra, Gaurav Dhungana and Brian Tetreault, “Sharing Ships’ Weather Data via AIS.”

EGNOS for Maritime Navigation

The European Geostationary Navigation Overlay System (EGNOS), which has been providing guidance to civil aviation since 2011, also can support maritime, railway and road applications. This paper assesses its use for maritime navigation compliant with International Maritime Organization (IMO) requirements for harbor entrances, harbor approaches and coastal waters: 99.8% of signal availability, 99.8% of service availability, 99.97% of service continuity, and 10 meters of horizontal accuracy. A kinematic test campaign was conducted in the waters of the Canary Islands using a geodetic multi-frequency, multi-constellation receiver-antenna pair installed aboard two vessels. The EGNOS Maritime Service met all IMO requirements by achieving a signal availability of 99.999%, a service availability in 99.9% of a predefined rectangular region, and 1.06 meters of horizontal accuracy at the 95th percentile. The service continuity requirement, however, was met in only 62.50% of the predefined region. Therefore, the paper concludes that the continuity risk is the most limiting factor for expanding the EGNOS Maritime Service along the coastal waters of the Canary Islands.

López Salcedo, Huamin Jia, Francisco Javier Pancorbo Garcia, Carlos Garcia Daroca, Irene Martin Calle, Santos Rodrigo Abadía Heredia and Manuel López Martínez, “A Kinematic Campaign to Evaluate EGNOS 1046 Maritime Service.”

Options for Integrity

Many maritime authorities are considering how to maintain the integrity of navigation systems as their infrastructure ages, especially given that the need for integrity in the user position is expected to increase with e-navigation services and for autonomous vessels. In harbor entrances, harbor approaches and coastal waters, the International Association of Marine Aids to Navigation and Lighthouse Authorities (IALA) prescribes an absolute horizontal accuracy of ≤10 meters 95% of the time, with an integrity risk of 99.99999%. Today’s GNSS more than meets that accuracy requirement, so the driver is integrity. Options for integrity are marine radiobeacon DGPS/DGNSS, the primary augmentation system in use today; receiver autonomous integrity monitoring (RAIM); satellite-based augmentation systems (SBAS); and others (such as commercial services or inertial.). The European MarRINav project is investigating resilient PNT options to support UK Critical National Infrastructure. Part of this work is comparing EGNOS and marine radiobeacon DGPS performance to inform international discussions and receiver standardization.

Citation. Alan Grant, George Shaw and Martin Bransby, “Considering SBAS and marine radiobeacon corrections to support safe maritime operations.”

Evaluation of WAAS for Use in Canadian Waters

Mariners navigating in Canadian waters use a ground-based augmentation system (GBAS) that provides differential corrections and integrity monitoring of GPS. This GBAS has been provided since 1994 by the Canadian Coast Guard (CCG) in the form of a differential GPS (DGPS) broadcast service. The service is only provided south of latitude 60°N in collaboration with the U.S. Coast Guard. Before embarking on a recapitalization program of its 24-year-old DGPS, and given that the U.S. Coast Guard is progressively shutting down its National Differential GPS sites, the CCG is evaluating options for its own DGPS network. Options include the wide-area augmentation system (WAAS), originally developed by the U.S. Federal Aviation Administration for civil aviation. This paper describes the authors’ evaluation for the CCG to determine the expected accuracy, integrity and availability of WAAS throughout Canadian waters, concluding that the current WAAS provides acceptable accuracy and integrity for most of Canada, excluding the higher latitudes.

GNSS + INS for Attitude Determination

Attitude determination (AD) is an important navigation component for ships and spacecraft. GNSS enables resolving their orientation in a precise and absolute manner, by employing multiple antennas rigidly mounted on the vessel. This requires carrier-phase observations, with the consequent added complexity of resolving integer ambiguities. Inertial aiding has been extensively exploited for AD, because it enables tracking fast rotation variations and bridging short periods of GNSS outage. In this paper, the fusion of inertial and GNSS information is exploited within the recursive Bayesian estimation framework, applying an Error State Kalman Filter, which, unlike common Kalman filters, tracks the error or variations in the state estimate, posing meaningful advantages for AD. The results show that the inertial aiding, along with a constrained attitude model for the float estimation, significantly improve the performance of attitude determination compared to classical unaided baseline tracking.

The U.S. Department of Transportation on Wednesday released updated guidelines for autonomous vehicles.

“Ensuring American Leadership in Automated Vehicle Technologies: Automated Vehicles 4.0” (AV 4.0) was announced by U.S. Transportation Secretary Elaine L. Chao in a keynote speech at CES 2020 in Las Vegas.

AV 4.0 unifies efforts in automated vehicles across 38 federal departments, independent agencies, commissions and executive offices, providing high-level guidance to state and local governments, innovators and stakeholders on the U.S. government’s approach toward autonomous vehicles.

“AV 4.0 will ensure American leadership in AV technology development and integration by providing unified guidance for the first time across the federal government for innovators and stakeholders,” Chao said.

AV 4.0 establishes federal principles for the development and integration of automated vehicles, consisting of three core focus areas: prioritize safety and security, promote innovation, and ensure a consistent regulatory approach.

It also outlines ongoing administration efforts supporting autonomous vehicle technology growth and leadership, as well as opportunities for collaboration including federal investments in the sector and resources for innovators, researchers and the public.

“AV 4.0 brings all of the important work happening on automated vehicle technologies across the federal government under one unified approach. The federal principles released today help foster an environment for innovators to advance safe AV technologies, and put the U.S. in a position of continued leadership in the future of transportation,” said U.S. Chief Technology Officer Michael Kratsios.

The USDOT is preparing for emerging technologies by engaging with new technologies to address legitimate public concerns about safety, security and privacy without hampering innovation, the department said in a press release.

With the release of “Automated Driving Systems 2.0: A Vision for Safety” (ADS 2.0) in September 2017, the USDOT provided voluntary guidance to industry, as well as technical assistance and best practices to states, offering a path forward for the safe testing and integration of Automated Driving Systems.

In October 2018, “Preparing for the Future of Transportation: Automated Vehicles 3.0” (AV 3.0) introduced guiding principles for autonomous vehicle innovation for all surface transportation modes, and described the USDOT’s strategy to address existing barriers to potential safety benefits and progress.

“AV 4.0 builds on these efforts by presenting a unifying posture to inform collaborative efforts in automated vehicles for all stakeholders and outlines past and current federal government efforts to ensure the United States leads the world in AV technology development and integration while prioritizing safety, security, and privacy and safeguarding the freedoms enjoyed by Americans,” the press release stated.

AV 4.0 will be published in the Federal Register for public review and comment. More information on the USDOT’s work on automated vehicles can be found at https://www.transportation.gov/av/4.

Snapdragon Ride is an advanced, scalable and open autonomous driving solution consisting of the family of Snapdragon Ride Safety system-on-chips (SoCs), Snapdragon Ride Safety Accelerator and Snapdragon Ride Autonomous Stack.

CES 2020, the massive annual consumer electronics show, is taking place Jan. 7-10 in Las Vegas.

Snapdragon Ride aims to address the complexity of autonomous driving and ADAS by leveraging its high-performance, power-efficient hardware, industry-leading artificial intelligence (AI) technologies and pioneering autonomous driving stack to deliver a comprehensive, cost and energy efficient systems solution.

The unique combination of Snapdragon Ride SoCs, accelerator and autonomous stack offers automakers a scalable solution designed to support three industry segments of autonomous systems, namely L1/L2 Active Safety ADAS for vehicles that include automatic emergency braking, traffic sign recognition and lane keeping assist functions; L2+ Convenience ADAS for vehicles featuring Automated Highway Driving, Self-Parking and Urban Driving in Stop-and-Go traffic; and L4/L5 Fully Autonomous Driving for autonomous urban driving, robo-taxis and robo-logistics.

The Snapdragon Ride Platform, based on the Snapdragon family of automotive SoCs and accelerator, is built on scalable and modular heterogeneous high-performance multi-core CPUs, energy efficient AI and computer vision (CV) engines, industry-leading GPU.

The platform with combination of SoCs and accelerator can be used as needed to address every market segment offering industry-leading thermal efficiency, from 30 Tera Operations Per Second (TOPS) for L1/L2 applications to over 700 TOPS at 130W for L4/L5 driving.

HERE’s new HD GNSS enables sub-meter positioning for mass market

The company also announces that HERE Navigation On-Demand is OEM-ready with APCOA as partner

HERE Technologies has introduced at CES 2020 its High Definition Global Navigation Satellite System (HD GNSS) positioning, a cloud-based solution that enables mass-market devices to achieve sub-meter accuracy across the globe.

CES 2020, the massive annual consumer electronics show, is taking place Jan. 7-10 in Las Vegas. Here’s booth is at Central Plaza, Tech East.

HD GNSS enables new user experiences with lane-level navigation, augmented and virtual reality. It combines precise point positioning (PPP) and real-time kinematic (RTK) positioning methods, allowing for fast convergence time, high availability and global coverage.

It also supports off-the-shelf mobile devices and internet of things (IoT) trackers equipped with dual frequency chipsets such as the Broadcom BCM47765 and BCM47755.

More mass-market devices and vehicles are being equipped with dual-frequency GNSS receivers. With the HD GNSS service, the receivers enable high-precision positioning, HERE said, a capability that was cost and geographically prohibitive less than two years ago.

HERE HD GNSS accelerates chipset, hardware and software makers’ ability to offer a step change in what can be delivered to consumers in new product capabilities, features and user experiences, the company said.

HERE HD GNSS data delivery is optimized for mobile devices, requires no additional hardware and comes equipped with spoofing detection and phone sensor integration. It provides global coverage (including China and Japan), with single-frequency mobile device support in the future.

HERE is also working across a partner ecosystem — including reference station operators, chipset manufacturers, module makers, hardware vendors, mobile network operators and system integrators — to jointly improve the positioning accuracy to centimeter levels, and in more challenging environments such as urban canyons.

Automotive use cases

Autonomous driving. For safety, it’s critical that automated vehicles are designed with high levels of redundancy in positioning systems. If an automated vehicle gets caught in bad weather conditions which are degrading optical sensor operations, <0.2m positioning accuracy available via HD GNSS increases safety and operation time in autonomous mode.

Assisted driving. In case of an obstacle on the road, HD GNSS combined with HERE HD maps provide obstacle indication and avoidance functionality.

Mobile device use cases

Road lane guidance and improved ETAs on mobile devices. If a driver is unfamiliar with the roadway, HERE HD GNSS, combined with precision HERE map data, shows the driver the correct lane and path to navigate to the destination fast and safely.

Improved gaming and augmented reality experience. Location-based games are growing and widely popular, however they currently rely on less accurate positioning technologies that inhibit next generation use cases. HERE HD GNSS bring exciting opportunities to design the next version of games with sub-meter positional accuracy.

Uber and Hyundai release full-scale air taxi model at CES
Hyundai is the first Uber Elevate partner with manufacturing capabilities to mass produce Uber Air Taxis

Uber and Hyundai Motor Company announced at CES 2020 a new partnership to develop Uber Air Taxis for a future aerial ride-share network and unveiled a full-scale aircraft concept. Hyundai is the first automotive company to join the Uber Elevate initiative, bringing automotive-scale manufacturing capability and a track record of mass-producing electric vehicles.

CES 2020, the massive annual consumer electronics show, is taking place Jan. 7-10 in Las Vegas. Hyundai Motor’s innovative smart mobility solutions including UAM, PBV, Hub and more are showcased at Booth 5431 in the Las Vegas Convention Center North Hall.

The taxi concept was created in part through Uber’s open design process, a NASA-inspired approach that jump starts innovation by publicly releasing vehicle design concepts so any company can use them to innovate their air taxi models and engineering technologies.

In this partnership, Hyundai will produce and deploy the air vehicles, and Uber will provide airspace support services, connections to ground transportation, and customer interfaces through an aerial ride-share network. Both parties are collaborating on infrastructure concepts to support take-off and landing for this new class of vehicles.

“Our vision of urban air mobility will transform the concept of urban transportation,” said Jaiwon Shin, Executive Vice President and Head of Hyundai’s Urban Air Mobility (UAM) Division. “We expect UAM to vitalize urban communities and provide more quality time to people. We are confident that Uber Elevate is the right partner to make this innovative product readily available to as many customers as possible.”

“Hyundai is our first vehicle partner with experience of manufacturing passenger cars on a global scale. We believe Hyundai has the potential to build Uber Air vehicles at rates unseen in the current aerospace industry, producing high quality, reliable aircraft at high volumes to drive down passenger costs per trip. Combining Hyundai’s manufacturing muscle with Uber’s technology platform represents a giant leap forward for launching a vibrant air taxi network in the coming years,” said Eric Allison, head of Uber Elevate.

In preparation for this announcement, Hyundai worked with Uber Elevate to develop a PAV (personal air vehicle) model, S-A1, that uses innovative design processes to optimize electric vertical take-off and landing (eVTOL) aircraft for aerial ridesharing purposes. S-A1 previous eVTOL designs Uber Elevate has released in the following ways:
- It is designed for a cruising speed up to 180 miles/hr (290 km/hr), a cruising altitude of around 1,000-2,000 feet (300 – 600 mt) above ground, and to fly trips up to 60 mile (100 km).
- The Hyundai vehicle will be 100% electric, utilizing distributed electric propulsion and during peak hours will require about five to seven minutes for recharging.
- Hyundai’s electric aircraft utilizes distributed electric propulsion, powering multiple rotors and propellers around the airframe to increase safety by decreasing any single point of failure. Having several, smaller rotors also reduces noise relative to large rotor helicopters with combustion engines, which is very important to cities.
- The model is designed to take off vertically, transition to wing-borne lift in cruise, and then transition back to vertical flight to land.
- The Hyundai vehicle will be piloted initially, but over time they will become autonomous.
- The cabin is designed with four passenger seats, allowing riders to board and disembark easily and avoid the middle seat with enough space for a personal bag or backpack.
Ushering in the era of seamless mobility, Hyundai’s exploration of future urban transportation incorporates the electric PAV concept with a new ground transportation, the Purpose Built Vehicle (PBV) concept.

Hyundai’s vision for creating communities from future transit systems comes into focus with yet another new infrastructure concept, called the Hub. When many PBVs and PAVs are docked and connected to a Hub, they make a new public space where diverse groups of people can come together.

AVL adds Rohde & Schwarz GNSS simulation to vehicle test environment

A collaboration between AVL and Rohde & Schwarz, two providers of measuring and automotive testing systems, now permits the reproduction of realistic GNSS reception conditions for testbed vehicle testing. As a result, users can reliably test all aspects of GNSS-based vehicle positioning — a core functionality of autonomous vehicles.

AVL DRIVINGCUBE enables the reproducible testing of driver assistance systems and driving features for self-driving vehicles using a real vehicle within a virtual environment in a variety of different traffic situations. For that purpose, test drives are performed with a real, ready-to-drive vehicle on a chassis dynamometer or powertrain testbed.

With the help of realistic virtual driving scenarios, it is possible to test peripheral sensors, control systems and actuators inside the vehicle in a fully reproducible and reliable manner. Automated vehicle functions are thus sufficiently validated during development and even before testing on the proving ground.

The range of environment simulations carried out with AVL DRIVINGCUBE can now be extended to include GNSS signals, bringing simulation closer to reality than ever before. The vehicle’s GNSS receiver is stimulated realistically using GNSS signals generated on the testbed.

This way, technical engineers can identify exactly how sensors, automated driving features and other actuators respond inside the vehicle. The now possible GNSS-based vehicle positioning feature is a core functionality of automated driving, and the approach ensures that it is reliably tested.

For generating GNSS signals, Rohde & Schwarz GNSS simulators are used (R&S SMBV100B or R&S SMW200A), which allow the generation of signals for all of the available satellite navigation systems (GPS, Glonass, Galileo, BeiDou, QZSS, SBAS) across all frequency bandwidths (L1, L2, L5). This also makes them suitable for testing multi-frequency receivers, which are playing an increasingly important role in automated driving.

“In Rohde & Schwarz, we now have a strong and reliable partner for GNSS stimulation. By generating consistent GNSS signals in connection with environment simulation, AVL DRIVINGCUBE now provides a test system that allows users to validate GNSS-based driver assistance systems and autonomous driving features,” explains Dr.-Ing. Tobias Düser, Head of Advanced Solution Lab at AVL Deutschland GmbH.

Christoph Pointner, Head of Signal Generators at Rohde & Schwarz, adds: “We are very pleased to bring our expertise in the field of signal generation to this collaboration with AVL and contribute to such an important innovation and trendsetting solution for testing automatized driving features.”

The additional GNSS stimulation makes testbed testing not only more realistic, it is above all a further step in moving testing from the road to the rig. This leads to a much sharper reduction of test drives than was the case previously and major savings in the kilometers driven.

Rohde & Schwarz GNSS stimulators form a flexible, modular system that can be adapted to your requirements and is easily integrated in the AVL DRIVINGCUBE environment. The stimulator is controlled automatically from the simulation platform. GNSS extensions for AVL DRIVINGCUBE are available with immediate effect.
