Multi-constellation & multi-frequency | Built-in geomagnetic sensor

supports RTK Centimeter-Level High-Precision Positioning

Features at a glance

RTK Mobile Station, RTK base station Centimeter positioning

Two Q43 GNSS Helical RTK Modules are used as an RTK Base Station
and RTK Mobile Station respectively

By setting up continuous running reference station and outputting the differential correction data on the ground known fixed coordinates using the Q43 module which is configured in base station mode, or by paid RTK base station enhanced services, transmitting differential correction data to Q43 terminals which uploading rough positioning data, the terminals, with errors like multipath refraction, Ionospheric, and Tropospheric Refraction, are able to calculate error value in real time, for centimeter-level positioning in seconds.

Concurrent reception of Multi-GNSS systems

Supports Multi-constellation systems, including GPS, BDS, GLONASS, Galileo, and QZSS

Supports Positioning Enhancement System

Supports A-GNSS positioning enhancement system, significantly reducing time to first fix and simultaneously improving the accuracy, integrity, reliability, and availability of positioning and navigation

Built-in geomagnetic sensor

Suitable for compass and electronic compass applications

Compatible with multiple programming platforms

Provides demos and user manuals for Raspberry Pi / Raspberry Pi Pico / Jetson Orin / ESP32 / Arduino, enabling easier development integration and strong scalability
