    U‑blox has announced the NEO-M9V module, its first GNSS positioning receiver to offer both untethered dead reckoning (UDR) and automotive dead reckoning (ADR).

    The NEO-M9V is suitable for fleet management and micro-mobility applications that require reliable meter-level positioning accuracy even in challenging GNSS signal environments such as urban canyons.

    Vehicle fleet managers seeking to cut costs and lower their carbon footprint depend on accurate positioning and navigation data to reduce fuel consumption. Micro-mobility operators need to accurately locate their individual bikes and scooters.

    Using inertial sensor measurements, UDR offers a smooth navigation experience in dense urban environments by bridging gaps in GNSS signal coverage and mitigating the impact of multipath effects caused by GNSS signals that bounce off buildings. ADR further increases positioning accuracy in demanding environments by including the vehicle speed in the sensor-fusion algorithm.

    Offering both UDR and ADR on the same module delivers maximum positioning performance and design flexibility, u-blox said. The NEO-M9V also features dynamic models optimized for both cars and e-scooters.

    NEO-M9V is based on the u‑blox M9 GNSS technology platform. Its ability to track up to four GNSS constellations maximizes the number of GNSS satellites within its line of sight at any given moment. Integrated SAW and low-noise amplifier filters offer excellent interference mitigation for a robust solution. Compatibility with the NEO form factor reduces migration efforts for customers upgrading existing designs.

    U-blox is introducing a series of automotive-grade positioning modules that are operational up to 105° C (221° F). The NEO-M9L modules and the M9140-KA-DR chip are built on the robust u-blox M9 GNSS platform and use dead-reckoning techniques to provide accurate position data when satellite signals are compromised or unavailable.

    The u-blox NEO-M9L-20A and NEO-M9L-01A modules, as well as the M9140-KA-DR chip, are specially designed for first-mount automotive solutions. The modules and the chip are all automotive-grade, with the NEO-M9L-01A variant offering an extended operational temperature range up to 105 °C, making it suitable for integration on the roof, behind the windscreen, or inside hot electronics control units.

    Applications include integrated navigation systems such as in-vehicle infotainment (IVI) and head units, integrated telematics control units and V2X.

    The modules include new-generation 6-axis inertial measurement units (IMUs) that deliver low-latency 100-Hz RAW data output. The modules offer a low-latency 50-Hz position update rate, making it suitable for use in real-time applications. The automotive dead-reckoning (ADR) output combines the GNSS fix with IMU data to deliver accurate positioning output for various scenarios.

    Additional GNSS-only output enables seamless integration into a variety of third-party applications. The receiver also supports wake-on-motion, which enables smart features such as theft protection and power-efficient designs.

    The modules offer innovative sensor-based spoofing detection for advanced security and robustness. The chip offers protection against possible GNSS signal spoofing, which can cause navigation systems to report faulty position data or time.

    “The u-blox M9 sensor-fusion products address the latest automotive market demands for quality, reliability and robustness. Availability and trustworthiness of position output are increased by using concurrent reception of four GNSS constellations,” said Aravinthan Athmanathan, product manager, Product Center Positioning at u-blox. “In addition, the spoofing-detection feature is brought to a new level compared to the predecessor. Paired with low-latency position output, attitude, and sensor data, the u-blox NEO-M9L is ready to meet current and future challenges facing the automotive market.”

    All the module variants are compliant with AEC-Q104, the latest standard for ensuring the reliability of modules used in automotive applications. Engineering samples and evaluation kits will be available by the end of September.
