The NEO-M8L automotive dead reckoning (ADR) module, made by u-blox, features integrated motion, direction and elevation sensors. By combining a gyroscope and accelerometer with the advanced M8 GNSS (global navigation satellite system) platform, the chip achieves exceptional performance in both indoor and outdoor applications that demand high accuracy.
In addition to accessing the integrated module’s gyro and accelerometer data, accident reconstruction systems can provide the location of an accident to facilitate insurance claims even if a collision occurs in a tunnel or park house. High-end navigation devices can be made to guide drivers through tunnels of several kilometres thanks to the ADR system, while stolen vehicles can be located instantly due to continuous monitoring of sensor data and storage of location in non-volatile memory.
Measuring 12,2 x 16,0 x 2,5 mm, the NEO-M8L requires minimum host integration and features an odometer function and autonomous data logging. The installed module’s functioning is not affected by its orientation, making it ideal for all road vehicle applications requiring reliable and uninterrupted position in challenging environments such as urban canyons, tunnels and underground parking.
The module is able to track all visible GNSS satellites including GPS, GLONASS, BeiDou, QZSS and all SBAS; Europe’s Galileo constellation will be supported in a future firmware version. Concurrent reception of two GNSS systems is supported, and the module can output its position up to 20 times per second.
