MicoAir MG-902 GNSS Module

Introduction

• MG-902 GNSS module integrates a u-blox 9th generation receiver chip – M9140 and the magnetic sensor – QMC5883L. It supports all L1 GNSS signals (GPS/GLONASS/Galieo/BeiDou) and can use up to 32 satellites simultaneously for navigation.
• The high-gain 25 x 25 x 4mm patch antenna provides the best performance.
• u-blox M9 receivers support concurrent reception of four GNSS.The high number of visible satellites allows the receiver to select the best signals. This maximizes the position accuracy, in particular under challenging conditions such as deep urban canyons.
• The M9 receiver also provides higher navigation rate and improved security features compared to previous u-blox GNSS generations.
• Built-in flash, parameters can still be saved when MG-902 lost power.
