SparkFun GPS-RTK Dead Reckoning Boards

SparkFun GPS-RTK Dead Reckoning Boards are high-precision sensor fusion GPS boards that use u-blox’s Automotive Dead Reckoning (ADR) technology. The SparkFun modules provide an accurate and continuous position with a 3D IMU sensor, wheel ticks, vehicle dynamics model, correction data, and GNSS measurements. The boards are available as a pHAT for Raspberry Pi or ZED-F9R (Qwiic) systems. The modules feature a 184-channel u-blox F9 engine GNSS receiver that receives signals from GPS, GLONASS, Galileo, and BeiDou constellations with ~0.2 meter accuracy.
