PRODUCT DESCRIPTION

Enhanced Dual Band Multi System RTK Positioning Module

Product Introduction

MQ-126N is a new generation BDS, GPS, GLONASS, Galileo, QZSS dual frequency multi system centimeter level RTK Positioning module. The module Based on integrated GNSS chip with RF baseband and high-precision algorithms.

Built-in high-performance CPU, and integrated dual floating point processor and RTK dedicated coprocessor. It can achieve RTK positioning result out up to 10Hz. Provide more powerful satellite processing capabilities.

The size is 16.0x12.2x2.4mm, It use SMT pads and supports the full automatic integration of standard access and reflow soldering. Support working module as UART. It can be applied to high-precision positioning applications.
