RTK2B – 4G NTRIP Starter Kit

The GPS-RTK Dead Reckoning Breakout features u-blox’s high-precision ZED-F9R module, delivering real-time kinematic (RTK) positioning with centimeter-level accuracy even in challenging environments like urban canyons or under canopy.

Designed for robotics, autonomous vehicles, and marine navigation, the ZED-F9R combines multi-band GNSS, 6-axis IMU sensors, and wheel-tick / odometer inputs for robust dead-reckoning when satellite signals are degraded or lost.

The board connects easily via the Qwiic ecosystem, supports UART, I²C, and USB, and integrates seamlessly with u-blox’s U-Center software for configuration and visualization.

Key Features:

Multi-band GNSS receiver (GPS, GLONASS, Galileo, BeiDou)

Real-time kinematic (RTK) positioning, ±10 mm accuracy (with base station)

Built-in 6-axis IMU for dead-reckoning performance

Supports wheel-tick, IMU, and vehicle dynamics inputs

Qwiic-compatible for plug-and-play I²C connections

USB-C, UART, and I²C interfaces

5 V / 3.3 V logic compatible

Ideal for autonomous robots, UAVs, and USVs
