    Cohda Wireless has developed an advanced and versatile V2X connectivity solution to help pave the way for the introduction of connected vehicles on smart roads and highways across the globe.

    The MK6 RSU (roadside unit) and OBU (onboard unit) offer a comprehensive connectivity capability as standard features, including DSRC, C-V2X, LTE/5G and Wi-Fi/Bluetooth.

    The Australian-headquartered company believes the MK6 will expedite the rollout of cooperative intelligent transport systems (C-ITS) around the world. Cohda’s V2X stack and applications are widely deployed in the industry, and the MK6 is the company’s most capable, versatile and powerful platform to date.

    The dual concurrent technology capability of the MK6 gives users the reliability, flexibility and interoperability needed to embark on deployments with confidence, no matter where they are in the world, said Paul Gray, Cohda Wireless chief executive officer.

    “More and more cities across the world are actively embarking on initiatives to introduce connected vehicles on their roads and we developed the MK6 with the intent that it would become the undisputed connectivity solution of choice,” Gray explained.“City transport authorities want to invest confidently in future-proof products, and when they equip their traffic lights and other roadside infrastructure with the MK6 Road-Side Unit, they are deploying a road-ready solution that can reduce congestion and road accidents.”

    The MK6 also offers improved security and processing power for unique and complex applications, Gray said.

    In developing the sixth-generation MK6, Cohda applied its experience and involvement in some of the world’s most prolific trials and deployments, including the 3,000-vehicle New York Connected Vehicle Project as well as Australia’s largest connected vehicle pilot, the Ipswich Connected Vehicle Project.

    Cohda’s technology has featured in two production vehicle platforms, most recently in 2019 when Volkswagen equipped its Golf 8 production model with Cohda’s V2X. Volkswagen is the second manufacturer to incorporate Cohda’s V2X technology in a production vehicle in readiness for an impending connected road transport system.

    “We are approaching a tipping point and we expect the MK6 to be a catalyst for increased momentum,” explained Gray.

    “The MK6 is the all-rounder solution that makes it easy for the entire industry, especially cities and transport authorities, to participate in the evolution of the world’s transport systems,” Gray added.

    The MK6 features the RoadLink SAF5400 and SXF1800 chipsets from NXP Semiconductors, as well as the Qualcomm Snapdragon Auto 5G Modem-RF Platform. It will be available in December.

    Increasing urbanization is creating pressure to manage housing, utilities and infrastructure holistically. Hence the concept of digital twins. Digital twins enable the integrated operation and maintenance of any geospatial asset to meet the increased demand for efficient and intelligent transportation systems, the green expansion of urban areas and sustainable infrastructure.

    Traditional GNSS or optical measurement instruments no longer suffice to capture all the necessary information in a timely manner and with the right levels of detail. Integrating technological advances — GNSS, inertial systems, lidar sensors and 360° spherical imagery — into a single mobile-mapping system has greatly increased the ability to produce complete 3D models with high accuracy and precision. Mobile mapping also directly reduces workload, lowers project costs, simplifies data use, and provides reality-based design.

    Mobile mapping surveys have been proven to be four to 10 times faster and three to seven times less expensive than traditional methods, delivering the required results up to three times faster. Integrated, multi-platform mobile-mapping solutions bridge the gap between the real world and the digital world for greater interoperability and accessibility of data in near real-time.

    The high-accuracy and cross-platform design of CHC Navigation’s AlphaUni 900 lidar system provides an innovative solution for 3D spatio-temporal data acquisition, which is necessary for the digital transformation of the AEC industry.

    Smart Cities

    After developing for more than a decade, digital-twin technology is now a complex and comprehensive technical system to support the construction of new smart cities. It is an advanced model for the continuous innovation of urban development and a future form of modernization combining the virtual and real worlds. The creation of digital-twin cities brings to the forefront high-level topographic tools capable of providing comprehensive, multi-dimensional, large-scale, high-resolution data sets.

    To illustrate typical digital-city projects, CHC Navigation conducted a proof-of-concept demonstration in the Jinshan District of Shanghai, which covers an area of about 600 square kilometers. This area has rich terrain features and characteristics typical of large modern cities, such as tall buildings, power lines, rivers and vegetation.

    Versatile and easy-to-use platforms are essential for the democratization of lidar systems. Capturing 3D data with a single-platform lidar system can leave some areas blank in the point-cloud data. The AlphaUni900 lidar solution, with its multi-platform capability, can easily capture complete data from a UAV, car, backpack or unmanned surface vessel (USV) and provide a sophisticated and comprehensive 3D model. The AlphaUni 900 integrates seamlessly with real buildings, provides exterior and interior mapping, and dramatically changes the way high-precision data is collected.

    The derived 3D models can be easily merged and correlated with social or economic spatial data, for example from building-integrated internet of things (IoT) and cloud computing data. As a result, complex operations can be optimized in real time, potential problems can be anticipated, and planned maintenance can be implemented to ensure the sustainability of urbanization projects over their entire lifespan, all in a fully connected model.

    Affordable, user-friendly solutions for capturing and processing airborne lidar data and imagery have triggered a strong adoption of UAV technology in the AEC industry. For CHC Navigation, 2021 was marked by the huge success of the AlphaAir 450, a breakthrough in 3D UAV mapping technology. With its ease of use, high accuracy and affordability, the AA450 expands the scope of lidar surveying to non-professional users in geospatial reality-capture applications and to those who have never been able to afford such technology before.

    SkyTraq introduces GPS/GAGAN receiver module for Indian market

    SkyTraq Technology Inc., a fabless GNSS positioning technology company, has introduced the S1216F8-GI2, a NavIC + GPS/GAGAN receiver module for the emerging Indian market.

    It integrates L1/L5 RF front-end and baseband processor capable of receiving up to 14 L5 NavIC signals and up to 20 L1 GPS/GAGAN signals simultaneously. With currently usable six NavIC signals and three GAGAN signals, it offers a total of 18-23 usable signals for navigation compared to 9-14 usable signals with conventional GPS receivers, providing improved accuracy in urban canyon environments with signals often blocked by high buildings.

    The S1216F8-GI2 has form-factor and pin-out compatability with popular 12 x 16-millimeter GPS receiver modules, so customers using those GPS modules can effortlessly migrate to NavIC/GPS capability by drop-in replacement and changing to an L1/L5 antenna.

    For emerging intelligent transport systems (ITS) applications requiring NavIC/GPS capability in India, S1216F8-GI2 enables fast time-to-market for product manufacturers, the company said.

    NavIC sub-frame data output is a useful feature of the S1216F8-GI2. It can output NavIC broadcast warning messages related to weather alerts, forecast, and natural disasters such as cyclones, earthquakes and tsunamis.

    An S1216F8-GI2 engineering sample, evaluation kit and datasheet is available. Volume delivery to customers begins in late March. The S1216F8-GI2 is manufactured with ISO/TS 16949 automotive certification.
