The SparkFun GNSS Flex pHAT - mosaic-X5 & IM19 IMU is an advanced all-in-one module designed to deliver survey-grade, millimeter-level RTK precision with comprehensive tilt compensation. This device is particularly suited for professional surveying, industrial robotics, and critical autonomous systems, offering exceptional accuracy and reliability. It integrates seamlessly with Raspberry Pi or similar single-board computers, requiring an external antenna for optimal performance.
Equipped with the Septentrio mosaic-X5 multi-band, multi-constellation receiver, the module provides millimeter-level accuracy, achieving 6mm horizontal and 1cm vertical precision with RTK. It supports a wide range of satellite constellations, including GPS, GLONASS, Galileo, BeiDou, and NavIC, ensuring robust and versatile tracking capabilities. The inclusion of AIM+ Interference Mitigation technology further enhances its performance by reducing signal interference.
The device also features the Feyman IM19 IMU, which offers high-precision attitude measurements and tilt compensation, enabling continuous navigation through sensor fusion. Connectivity is facilitated through a standard 40-pin GPIO header for Raspberry Pi, a dedicated USB-C port for high-speed data access, and a microSD card slot for data logging. The module supports both browser-based and command-line interfaces for user control.
