The NEO-M9L module is built on the robust u‑blox M9 GNSS chip, which provides exceptional sensitivity and acquisition times for all L1 GNSS systems. The u‑blox M9 standard precision GNSS platform, which delivers meter-level accuracy, succeeds the well-known u‑blox M8 product range.

NEO-M9L is an ultra-robust dead reckoning module with an integrated Inertial Measurement Unit (IMU) that can also output GNSS-only positioning data in parallel to the sensorfused data. The sophisticated built-in algorithms fuse IMU data, GNSS measurements, wheel ticks, and vehicle dynamics to provide optimal positioning accuracy where GNSS alone would fail.

NEO-M9L supports concurrent reception of four GNSS constellations. The high number of visible satellites enables the receiver to select the best signals. This maximizes position accuracy, particularly under challenging conditions, such as in deep urban canyons.

The device is a turnkey, self-contained solution that provides the best possible performance and accuracy with low latency. The u‑blox approach provides a transparent evaluation of the positioning solution and clear lines of responsibility for design support, while reducing the supply chain complexity during production.

In addition to RF-based jamming and spoofing detection, NEO-M9L implements sensor-based spoofing detection and in addition informs applications about possible security attacks.

NEO-M9L offers backwards pin-to-pin compatibility with the previous u‑blox generations' modules, and uses GNSS chips qualified according to AEC‑Q100 and manufactured in ISO/TS 16949-certified sites. Module qualification tests are performed as stipulated in the AEC-Q104 standard.
