It is aimed at professional surveying, industrial robotics and autonomous navigation applications where reliable position and attitude data are critical.It is part of the SparkPNT Flex ecosystem, so the receiver module can be swapped for repairs or future upgrades. The carrier connection breaks out useful interfaces including multiple UARTs, USB, SD card access, I2C, PPS, LEDs and event signals.The mosaic-X5 can be configured through its browser-based interface over USB, or via a command-line interface for deeper control and automated workflows. By default, COM4 on the mosaic-X5 is connected to UART2 on the IM19 so the IMU receives NMEA data and outputs compensated position and attitude data.This module requires a GNSS Flex carrier board and an external GNSS antenna. Antenna connection is available via the module’s U.FL connector, or via an SMA connector on a compatible GNSS Flex pHAT carrier using a short U.FL jumper cable.Features:SparkPNT Flex ecosystem: Designed to be easily swappable for repairs or future upgrades.Millimetre-level RTK accuracy: Delivers 6mm horizontal and 1cm vertical accuracy with RTK, plus timing precision down to five nanoseconds.AIM+ interference mitigation: Septentrio AIM+ anti-jamming and anti-spoofing technology for robust operation in noisy RF environments.Multi-band and multi-constellation: Tracks signals from GPS, GLONASS, Galileo, BeiDou and NavIC for strong satellite availability.Survey-grade attitude accuracy: IM19 roll and pitch measurements are accurate to within 0.05 degrees.Tilt compensation: Calculates a virtual digital level point at any tilt angle for faster field data collection.Sensor fusion: Provides dead reckoning during momentary GNSS signal loss in urban or obstructed environments.Browser-based interface: Access the mosaic-X5 built-in web server via USB for setup, monitoring and data logging.Command-line interface: Full CLI available for configuration, control and automated testing.Pre-configured for fusion: mosaic-X5 COM4 is linked to IM19 UART2 by default, and the link can be reconfigured with onboard jumpers.External antenna options: Use the onboard U.FL connector or a sturdier SMA connector on a compatible GNSS Flex pHAT carrier board.Specifications:Module configuration: GNSS Flex Module -
