Features:

• The SparkFun ZED-F9R GPS pHAT is a high precision, sensor fusion GPS board with equally impressive configuration options and takes advantage of u-blox’s Automotive Dead Reckoning (ADR) technology.
• The ZED-F9R module provides a highly accurate and continuous position by fusing a 3D IMU sensor, wheel ticks, a vehicle dynamics model, correction data, and GNSS measurements.
• The ZED-F9R module is a 184-channel u-blox F9 engine GNSS receiver, meaning it can receive signals from the GPS, GLONASS, Galileo, and BeiDou constellations with ~0.2 meter accuracy!
