u-blox is introducing 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 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.

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

The modules include new generation 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, making it ideal for use in real-time applications. The automotive dead reckoning (ADR) output smartly combines the GNSS fix with IMU data to deliver the most accurate positioning output for the given scenario. 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.
