Introduction

High Precision Integrated Navigation Positioning Module

ER-GNSS-M02 is a new cost-effective and high-precision integrated navigation and positioning module, which supports the multi-frequency signal reception of the whole constellation. The module adopts M02PIN LGA package, 17mm*22mm small size, high integration, low power consumption. ER-GNSS-M02 module is equipped with high precision RTK algorithm engine, which supports long baseline RTK solution and fast initialization. Built-in IMU, using tight combination algorithm, can continuously output stable and reliable navigation and positioning data in areas where satellite signals are seriously blocked. The ER-GNSS-M02's small size and low power design and excellent navigation and positioning performance can be widely used in high-precision GIS equipment, UAV, autonomous driving, agriculture and construction machinery and other fields.
