The NEO-M8U module introduces u-blox’s Untethered Dead Reckoning (UDR) technology, which provides continuous navigation without requiring speed information from the vehicle. This innovative technology brings the benefits of dead reckoning to installations previously restricted to using GNSS alone and significantly reduces the cost of installation for after-market dead reckoning applications.

The strength of UDR is particularly apparent under poor signal conditions, where it brings continuous positioning in urban en­vironments, even to devices with antennas installed within the vehicle. Useful positioning performance is also available during complete signal loss, for example in parking garages and short tunnels. With UDR, positioning starts as soon as power is ap­plied to the module, before the first GNSS fix is available.

The NEO-M8U may be installed in any position within the vehicle without configuration. In addition to its freedom from any electrical connection to the vehicle, the on-board acceler­ometer and gyroscope sensors result in a fully self-contained solution, perfect for rapid product development with reliable and consistent performance.

 The intelligent combination of GNSS and sensor measure­ments enables accurate, real-time positioning at rates up to 20 Hz, as needed for smooth and responsive interactive appli­cations. Native high rate sensor data is made available to host applications such as driving behaviour analysis or accident reconstruction.

The NEO-M8U includes u-blox’s latest generation GNSS receiver, which adds Galileo to the multi-constellation recep­tion that already includes 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 flexible connectivity and enable simple integration with most u-blox cellular modules.
