Product description
The NEO-M8L 3D Automotive Dead Reckoning (ADR) modules combine GNSS, inertial sensing, and speed information from
the vehicle to provide continuous and accurate positioning
for telematics, navigation and V2X applications. The position
engine tolerates missing wheel sensor data and also supports UDR mode without any wheel sensor data.
Incorporating u-blox’s latest advancements in multi-GNSS signal processing, the NEO-M8L delivers the ideal solution where navigation performance is the priority, regardless of GNSS signal quality or availability. In addition to the on­board sensors, NEO-M8L further eases installation with automatic conguration of speed or wheel-tick inputs, and compensation for in-vehicle antennas.
The intelligent combination of sensor measurements and
GNSS enables accurate, real-time positioning, speed and heading information at rates up to 30 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 with multi-constellation reception including Galileo, 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 exible connectivity and enable simple integration with most u-blox cellular modules.
NEO-M8L modules use GNSS chips qualied according to AEC-Q100 and are manufactured in ISO/ TS 16949 certied sites. Qualication tests are performed as stipulated in the ISO16750 standard: “Road vehicles – Environmental conditions and testing for electrical and electronic equipment”.
The NEO-M8L automotive grade module adheres to automotive industry standard quality specications and production ow.
