u-blox NEO-M9L positioning modules and M9140-KA-DR chip

u-blox introduces a series of automotive-grade positioning modules that are operational up to 105°C. 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 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 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 (ECUs). Applications include integrated navigation systems such as in-vehicle infotainment (IVI) and head units, integrated telematics control units (TCU) and V2X.

The modules include 6-axis inertial measurement units (IMUs) which deliver low-latency 100 Hz RAW data output. The modules offer a low-latency 50 Hz position update rate, suitable for use in real-time applications. The automotive dead reckoning (ADR) output combines the GNSS fix with IMU data to deliver the most accurate positioning output for the given scenario, the company claims. 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 security and robustness. The chip offers protection against possible GNSS signal spoofing, which can cause navigation systems to report faulty position data or time. All the module variants are compliant with AEC-Q104, the latest standard for modules used in automotive applications.
