1. Description

The NEO-M8U-04B module introduces u-blox's unrestricted dead reckoning (UDR) technology, which can provide continuous navigation without vehicle speed information. This innovation This technology brings the benefits of dead reckoning to installations that were previously limited to only using GNSS, and greatly reduces the installation cost of dead reckoning applications in the aftermarket. Under bad signal conditions, the strength of UDR is particularly obvious, because it will bring continuous Even on a device equipped with an antenna on a vehicle, it can be positioned in an urban environment. it works Provides positioning performance even if the signal is completely lost And a short tunnel. With UDR, you can start positioning as long as the module is powered on. The first GNSS fix is available. NEO-M8U can be installed anywhere on the vehicle without configuration. In addition Not affected by any electrical connection with the vehicle, on-board accelerometer and gyroscope The sensor can provide a completely independent solution and is ideal for reliable and rapid product development And have consistent performance. The intelligent combination of GNSS and sensor measurement can achieve accurate and real-time The maximum positioning frequency required for smooth and responsive interactive applications is 30 Hz. Local high-rate sensor data can be used in host applications, such as driving behavior analysis Or the 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 (compliant with I2C) and The SPI interface option provides flexible connectivity and can be easily integrated with most u-blox Cellular module. The u-blox M8 module uses AEC-Q100 certified GNSS chip and is manufactured in ISO/TS 16,949 certified sites.
