NEO-M8L - u-blox Automotive Dead Reckoning M8 GNSS module, including 3D sensors

The NEO-M8L standalone module combines the high performance u-blox M8 concurrent positioning engine with u-blox 3D Automotive Dead Reckoning (ADR) technology.

The NEO-M8L 3D Automotive Dead Reckoning (ADR) modules combine GNSS, inertial sensing, and speed information from the vehicle to provide continuous and accurate 3D positioning for road vehicles.

Incorporating u-blox's latest advancements in multi-GNSS signal processing (now including Galileo), the latest version of NEO-M8L delivers the ideal solution where navigation performance is the priority, regardless of GNSS signal quality or availability. In addition to the on-board sensors, NEO-M8L further eases installation with automatic configuration of speed or wheel-tick inputs, and compensation for in-vehicle antennas.

The intelligent combination of GNSS and sensor measurements enables accurate, real-time positioning, speed and heading information at rates up to 20 Hz, as essential for smooth and responsive interactive display. Access to native, high rate sensor data enables host applications to make full use of the receiver's assets.

The NEO-M8L includes u-blox's latest generation GNSS technology which adds Galileo to the multi-constellation reception that already includes GPS, GLONASS, BeiDou and QZSS. The module provides high sensitivity and fast GNSS signal acquisition and tracking.

UART, USB, DDC (I²C compliant) and SPI interface options provide flexible connectivity and enable simple integration with most u-blox cellular modules.
