NEO-M9L Dual-Output Automotive Dead Reckoning Module with Extended Operating Range up to 105 °C

14 July 2021 - 0 Comments

u‑blox has introduced a series of automotive-grade positioning modules that are operational up to 105 °C. New NEO-M9L modules and 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 modules and chip are specially designed for first-mount automotive solutions. 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 applications include integrated navigation systems such as in-vehicle infotainment (IVI) and head units, integrated telematics control units (TCU), and V2X.

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 (ECUs). 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.

Moreover, the automotive dead reckoning output smartly combines the GNSS fix with IMU data to deliver the most accurate positioning output for the given scenario. 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.
