1. Description

The NEO-M8U-0 module introduces u-blox's unrestricted dead reckoning (UDR) technology, which can provide continuous navigation without the vehicle providing speed information. This innovative technology brings the benefits of dead reckoning to installations that were previously limited to only using GNSS, and greatly reduces the installation cost of after-sales dead reckoning applications. Under bad signal conditions, the strength of UDR is particularly obvious. In an urban environment, UDR can still achieve continuous positioning even in a device with an antenna installed in the vehicle. In the case of complete signal loss, useful positioning performance can also be used. With UDR, positioning will begin once the module is powered up before the first GNSS fix is available. NEO-M8U can be installed anywhere on the vehicle without configuration. In addition to avoiding any electrical connection with the vehicle, the on-board accelerometer and gyroscope sensor also provide a completely independent solution, which is ideal for rapid product development with reliable and consistent performance. The intelligent combination of GNSS and sensor measurements can achieve accurate, real-time positioning at rates up to 30 Hz, which is essential for smoothly responsive interactive applications. The raw high-rate sensor data can be used in host applications, such as driving behavior analysis or accident reconstruction. 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. This module provides high sensitivity and fast GNSS signal acquisition and tracking. UART, USB, DDC (I2C compatible) and SPI interface options provide flexible connectivity and can be easily integrated with most u-blox cellular modules.
