The NEO-M8U is the industry’s first 3D untethered-dead-reckoning (UDR) module, designed to provide accurate positioning for in-car navigation systems even where GNSS signals are weak or unavailable, such as in long tunnels. The module relies on the vehicle’s power for continuous operation and is not connected to the other sensors. The module combines multi-GNSS — U.S. GPS, Russian GLONASS, Chinese BeiDou, and European Galileo — with an onboard 3D gyro/accelerometer, and provides excellent multipath suppression, which improves GNSS position accuracy even in tough environments, such as urban canyons, short tunnels, and parking garages.
The multisensor behaves like a regular GNSS receiver and can be installed in the vehicle in any orientation. Other features include a real-time update rate of up to 20 Hz and high-speed access to the raw sensor data for tasks such as driving behavior analysis, as well as detection of sudden deceleration or acceleration, such as if you get into an accident. The module will be available in early Q2, and its pin and software compatibility with current NEO modules simplifies upgrading.
