Description
Q43 is an integrated GNSS RTK module with a helical antenna and geomagnetic sensor, designed for high-precision navigation systems, enabling stable positioning performance in mobile and industrial applications where accurate position and spatial orientation determination is required.
Multi-constellation, multi-frequency GNSS receiver with a 360° helical antenna and built-in geomagnetic sensor, ensuring stable operation within a wide 3.3–16 V voltage range, data update rates up to 10 Hz, and support for RTCM 3.3 and NMEA-0183 protocols in systems requiring precise synchronization and continuous measurement data transmission.
The Q43 GNSS Helical RTK Module integrates an RTK engine, helical antenna, and geomagnetic sensor within a single compact enclosure designed for easy installation in integrated systems. Reception of signals from multiple satellite systems (GPS, BeiDou, GLONASS, Galileo, QZSS) and multi-frequency operation enable centimeter-level RTK positioning in applications such as mobile robotics, surveying, precision agriculture, mining, and autonomous systems.
The integrated geomagnetic sensor enables heading determination relative to magnetic north, supporting orientation stabilization in mobile systems operating in the field, where conventional azimuth estimation based solely on satellite position may be insufficient. As a result, the module can simultaneously provide information about position and direction of movement, which is particularly important in applications such as autonomous robots, unmanned platforms, measurement systems, or navigation devices operating in dynamically changing environments. Combining positioning and heading detection functions within a single design simplifies system architecture, reduces the number of external components, and improves the consistency of data used by control and sensor fusion algorithms.
The module has been designed for operation in environments with elevated operational requirements, where simultaneous support for multiple satellite signal sources and resistance to interference typical of urban and industrial areas are essential. Thanks to precise time synchronization and high receiver sensitivity, it is possible to maintain a stable positioning solution even under conditions of partial sky obstruction, increasing the reliability of monitoring systems, telemetry, and IoT infrastructure utilizing real-time location data.
Compatible with Raspberry Pi, Raspberry Pi Pico, Jetson Orin, ESP32, and Arduino platforms, enabling easy integration with popular embedded environments as well as prototyping and industrial systems. Below, a detailed pinout description and compatibility information are provided.
