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
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.

Microchip releases MAC-SA5X, enhancing its miniature atomic clock (MAC) technology to deliver wider temperature range and rapid warm-up time
As reliance on precise frequency and timing increases due to GNSS enabling 5G communication networks, data centers and other mission critical infrastructure, smaller size and high-performance atomic clock technology has become essential to supporting both military and commercial applications.
To meet demand for a small-footprint atomic clock, Microchip Technology released a higher performance atomic clock for its size and power. The new device also delivers a wider thermal range, critical performance improvements and other enhancements over previously available technology, the company said.
Next-Gen Timing. Microchip’s next-generation MAC-SA5X miniaturized rubidium atomic clock produces a stable time and frequency reference that maintains a high degree of synchronization to a reference clock, such as a GNSS-derived signal.
Its combination of low monthly drift rate, short-term stability and stability during temperature changes allows the device to maintain precise frequency and timing requirements during extended periods of holdover during GNSS outages or for applications where large rack-mount clocks are not possible.

Operating over a wider temperature range of -40 to +75 Celsius, the MAC-SA5X was designed to quickly achieve atomic stability performance by taking less time to lock compared to some of the existing clock technology, Microchip said. In an aircraft application, for example, these attributes enable faster power up of critical communication and navigation systems in extreme climates.
The MAC-SA5X allows system developers to avoid the need for extra circuitry by integrating a one pulse per second (1PPS) input pin for fast frequency calibration, saving time and development cost. In addition, the MAC-SA5X is designed with the same footprint as previous generation miniature atomic clock technology, reducing the development time to transition to the newer, higher performance device.
“As an industry leader, Microchip continues to invest in next-generation atomic clock technology for Department of Defense programs, mission-critical infrastructure and networks that require a high degree of accuracy in timekeeping and synchronization,” said Randy Brudzinski, vice president and general manager of Microchip’s frequency and time business unit. “The MAC-SA5X adds several performance and feature enhancements while retaining the same footprint as the previous generation MAC-SA.3X products, enabling customers to easily transition to the new technology.”
Designed and manufactured in the U.S., the MAC-SA5X operates to the following additional specifications:
<5.0E-11 frequency stability over operating temperature;
<5.0E-11 per month aging rate; 6.3-watt power consumption;
47 cc in volume.
The MAC-SA5X provides backward compatibility with its predecessor MAC-SA.3Xm family and comes in an ovenized crystal oscillator (OCXO)-sized package of 50.8 mm x 50.8 mm.
Microchip has delivered more than 275,000 rubidium clocks, 120,000 chip-scale atomic clocks (CSACs), 12,500 Cesium clocks and 200 active hydrogen masers to customers worldwide.
Development Tools. The MAC-SA5x family of atomic clocks is supported by evaluation kit 090-44500-000.
Availability. The MAC-SA5X atomic clock is available now for pre-sampling, and will be available for deliveries in February. Microchip supports the MAC-SA5X with technical support services as well as an extended warranty.
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.
New modules enable entertainment, advanced connectivity features and next-generation artificial intelligence
Qualcomm Technologies has launched three new mobile platforms — the Qualcomm Snapdragon 720G, 662 and 460 — to enable enhanced user experiences across connectivity, gaming and entertainment.
The new mobile platforms support dual-frequency (L1 and L5) GNSS to improve location positioning accuracy and robustness. The system-on-chip solutions also support the Indian NavIC (Navigation with Indian Constellation).
Seven constellations. For the first time supported on mobile, the Qualcomm Location Suite now supports up to seven satellite constellations concurrently, including the use of all of NavIC’s operating satellites for more accurate location performance, faster time-to-first-fix (TTFF) position acquisition, and improved robustness of location-based services.
“ISRO is satisfied with the efforts of Qualcomm Technologies Inc. towards incorporating NavIC and we urge OEMs to leverage it for future handset launches in India,” said K. Sivan, chairman, ISRO. “The availability of NavIC across multiple mobile platforms will help enhance the geolocation capabilities of smartphones in the region and bring the benefits of this indigenous solution to Indian consumers for their day-to-day use.”
The new modules also enable fast 4G connectivity speeds, deliver key Wi-Fi 6 features and integrated Bluetooth 5.1 with advanced audio via the Qualcomm FastConnect 6-series subsystems.
Artificial Intelligence. Designed to deliver new and improved AI user experiences across photography, voice assistants and virtually always-on scenarios for increased contextual awareness, the new platforms also feature the Qualcomm AI Engine and Qualcomm Sensing Hub.
“While we see a fast adoption of 5G across geographies globally, we do recognize the phenomenal boost that 4G has given towards enabling broadband connectivity for Indian consumers. 4G will continue to remain a focus area for Qualcomm Technologies for regions like India, where it will stay a key technology for connectivity,” said Rajen Vagadia, vice president and president, Qualcomm India Pvt. Ltd. “Our goal is to enable our partners to continue creating solutions that offer seamless connectivity access and exceptional mobile experiences, that consumers can count on.”
“Today’s smartphone users want fast, seamless connectivity, advanced features and long-lasting battery life,” said Kedar Kondap, vice president, product management, Qualcomm Technologies, Inc. “This expansion of our 4G lineup enables our partners to offer sophisticated solutions that meet global demand and enable a remarkable gaming experience across multiple tiers and price segments.”

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.

‘Spoofing circles’ appear in China
“GPS spoofing circles” have been discovered at 20 locations along the Chinese coast, according to the non-profit environmental group Skytruth. Of the locations observed, 16 were oil terminals; the others were corporate and government offices. The spoofing in Shanghai resulted in reported positions from ships, fitness trackers and other GPS-enabled devices forming circles some distance from the shore — a phenomenon first observed by the non-profit C4ADS. Professor Todd Humphreys briefed the phenomena at an Institute of Navigation conference in September, and MIT Technology Review published an article about it in November 2019.
What improvements will GPS III bring to high -precision surveying? When? Will these improvements require any changes in equipment and/or processes?
Tony Agresta, Nearmap
“The biggest impact of GPS III to high precision surveying will be a full constellation of L5 satellites. Triple frequency will bring faster convergence times and better accuracy in more difficult conditions. GPS III will better align with Galileo and BeiDou with L1C which means better availability in restricted sky conditions. Users will want to have equipment capable of supporting these new signals, in antenna and receiver HW as well as the signal processing done on board.” Tony Agresta

Jean-Marie Sleewaegen
“Of all the improvements brought by GPS III, the new L1C signal will probably have the biggest impact on high-precision surveying. Compared to L1 C/A, L1C brings better reception in difficult environments, improved availability thanks to the “pilot” component, enhanced resilience to jamming attacks, and better interoperability with Galileo, BeiDou and QZSS. Many receivers do support L1C already, but the benefits will become more tangible as the GPS III constellation grows.” Jean-Marie Sleewaegen
