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 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 (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 new generation 6-axis inertial measurement units (IMUs) which designed to 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 positioning output for the given scenario. Additional GNSS-only output enables integration into 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 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.
