Untethered 3D dead-reckoning bridges gaps in automotive locations fixes

February 18, 2016 // By Graham Prophet
u-blox’ NEO-M8U is presented as the first Untethered 3D Dead Reckoning (UDR) module; combining multi-GNSS (GPS, GLONASS, BeiDou, Galileo) with an onboard 3D gyro/accelerometer, NEO-M8U provides accurate positioning even where GNSS signals are weak or not available. It achieves this without any connection to the vehicle other than power.

The u-blox NEO-M8U 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 area, NEO-M8U is typically three times more accurate than a traditional GNSS receiver. NEO-M8U offers instantaneous position immediately after power-up, without the need to wait for a first fix as with regular GNSS receivers.

Simplifying 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. With intelligent sensing and continuous self-calibration, NEO-M8U 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.

“NEO-M8U, with its performance and simplicity, is a game changer for a range of new use cases such as navigation, fleet management, road pricing, usage-based insurance and even ‘find-my-car’ applications,” says Andrew Miles, Product Manager, Dead Reckoning at u-blox. NEO-M8U will be available in early Q2, 2016. It can upgrade any existing NEO design via pin and software compatibility to other NEO modules.
