u-blox announced the release of NEO-M8U, the industry’s first Untethered 3D Dead Reckoning (UDR) module.
Combining multi-GNSS (GPS, GLONASS, BeiDou, Galileo) with an onboard 3D gyro/accelerometer, it provides accurate positioning even where GNSS signals are weak or unavailable. It achieves this without any connection to the vehicle other than power.
The module provides superior multipath suppression, which improves position accuracy even in tough environments such as urban canyons, tunnels or parking garages. For example, in London’s city centre, u-blox claims NEO-M8U is typically three times more accurate than a traditional GNSS receiver. In addition, it offers instantaneous position immediately after power-up, without the need to wait for a first fix as with regular GNSS receivers.
One of the device’s features is the ease of product development and installation: NEO-M8U looks and behaves just like a regular GNSS receiver and does not require any special mounting or connection to the vehicle. Thanks to its intelligent sensing and continuous self-calibration, it can be installed in the vehicle in any orientation.
Other features are its real-time update rate of up to 20 Hz benefiting a smooth navigation behaviour, as well as the high-speed access to the raw sensor data allowing for driving behaviour analysis and detection of sudden acceleration, such as during an accident.
