u-bloxNEO-M9V-20B
Overview
The NEO-M9V-20B is a high-performance GNSS receiver module from u-blox featuring Untethered Dead Reckoning (UDR) and Automotive Dead Reckoning (ADR) capabilities. It provides reliable positioning in challenging environments like urban canyons or tunnels by fusing GNSS data with internal inertial sensor measurements. This module supports concurrent reception of four GNSS constellations, including GPS, GLONASS, Galileo, and BeiDou, at a frequency of 1.561GHz.
Why Choose This Part
The module offers a high sensitivity of -160dBm and features integrated anti-jamming and anti-spoofing technology for enhanced security. Its ability to provide dual outputs (raw GNSS and fused GNSS+DR) gives engineers flexibility in how they process location data. Operating on a 2.7V to 3.6V supply, it maintains low power consumption with a tracking current of 49mA.
Applications
Key Specifications
Getting Started
Integrate the module using UART, I2C, SPI, or USB interfaces and configure it via the u-center evaluation software. For rapid prototyping, engineers often use the u-blox EVK-M9 evaluation kit to test dead reckoning performance. Ensure the 24-SMD module is placed with adequate clearance for the internal inertial sensors to function correctly during automatic alignment.
