SparkFun GNSS Flex pHAT - mosaic-X5 & IM19 IMU

Achieve the absolute pinnacle of positioning performance with your Raspberry Pi using the SparkFun mosaic-X5 & IM19 IMU GNSS Flex pHAT. This is one of our most advanced GNSS receiver boards combining the versatile Flex pHAT carrier with the industrial-grade millimeter-level mosaic-X5 RTK receiver and the high-precision IM19 IMU. It's the ultimate all-in-one solution for professional surveying industrial robotics and critical autonomous systems.The GNSS Flex pHAT acts as the bridge between your single-board computer (SBC) and the modular SparkPNT ecosystem. It mounts securely via an extended 40-pin header and connects to the included GNSS module using standardized 2x10-pin headers.Multiple SBC Compatibility: The 40-pin header is designed for a direct connection to a Raspberry Pi NVIDIA Jetson Orin Nano Google Coral or other compatible single-board computers.Native USB Access: A dedicated USB-C port connects directly to the mosaic-X5's USB hardware for high-speed data access to its web server.microSD Card Slot: Ideal for logging data on position velocity and time.Mounting Hardware Included: Comes with the necessary standoffs screws and an extended header for a clean stable setup.Survey-Grade RTK PrecisionAt the heart of this pHAT is the Septentrio mosaic-X5 a multi-band multi-constellation receiver known for its best-in-class reliability and performance.Millimeter-Level Accuracy: Delivers an astonishing 6mm horizontal and 1cm vertical accuracy with RTK plus timing precision down to five nanoseconds.AIM+ Interference Mitigation: Features Septentrio's unique AIM+ technology a powerful anti-jamming and anti-spoofing system that ensures unparalleled robustness and reliability in noisy RF environments.Multi-Band & Multi-Constellation: Tracks all signals from all major constellations (GPS GLONASS Galileo BeiDou NavIC) for maximum satellite availability and fast reliable fixes.Intelligent Tilt & Dead ReckoningPaired with the mosaic-X5 is the Feyman (FMI) IM19 IMU which combines MEMS sensor data with the GNSS RTK positioning data to provide high-precision attitude measurements. This enables advanced features such as tilt-compensated surveying and robust navigation during brief GNSS outages.Survey-Grade Accuracy: Delivers roll and pitch measurements accurate to within 0.05 degrees.Tilt Compensation: No more perfectly vertical survey poles! The IM19 can calculate a virtual digital level point at any tilt angle revolutionizing field data collection.Sensor Fusion: Provides a continuous navigation solution (dead reckoning) even during momentary GNSS signal loss perfect for urban or obstructed environments.Intuitive Control & Seamless IntegrationThis Flex Module is engineered to provide both a sophisticated user experience and a tightly integrated navigation solution setting it apart from typical receivers.Browser-Based Interface: Access the mosaic-X5's powerful built-in web server from any browser via the USB interface for intuitive setup monitoring and data logging.Command-Line Interface: For power users and automated testing a full Command-Line Interface (CLI) is also available for deep configuration and control.Pre-Configured for Fusion: By default the mosaic-X5's COM4 is linked to the IM19's UART2 automatically feeding it the necessary NMEA data. The IMU then outputs a fully compensated position and attitude. This link can be easily reconfigured via onboard jumpers to suit your specific project needs.This pHAT requires an external antenna. Users have a few options for connecting an external GNSS antenna to their GNSS receiver.The included GNSS Flex module has a U.FL connector for an external antenna.For a sturdier connection the SparkFun GNSS Flex pHAT includes an SMA connector bridged to a U.FL connector. Users simply need to jumper the U.FL connectors on both the SparkPNT GNSS Flex Module and SparkFun GNSS Flex pHAT with a short U.FL cable.This pHAT also requires a Raspberry Pi (or similar single-board computer). Users can find Raspberry Pi and NVIDIA single-board computers in our catalog. By default we use the Raspberry Pi's primary serial bus (i.e. TX: GPIO14/Pin 8; RX: GPIO15/Pin 9) to communicate with the GNSS receiver of the SparkPNT GNSS Flex module. However users can also utilize any of the other interfaces.
