GPS/GNSS boards offer dead reckoning and multiple constellations
SparkFun Electronics has released two GPS/GNSS boards, the ZED-F9R Breakout and ZED-F9R pHAT, both featuring Automotive Dead Reckoning from u-blox.

The boards allow connection to multiple constellations including GPS, GLONASS, BeiDou, Galileo and QZSS. The ZED-F9R pHAT connects to a Raspberry Pi to bring GPS/GNSS capabilities to the platform.

The SparkFun ZED-F9R GPS-RTK Dead Reckoning Breakout is a high precision, sensor fusion GNSS board with equally impressive configuration options. The ZED-F9R takes advantage of Automotive Dead Reckoning (ADR) technology from u-blox and provides a highly accurate, continuous position by fusing a 3D IMU sensor, wheel ticks, a vehicle dynamics model, correction data, and GNSS measurements. The ZED-F9R also allows for fast prototyping via I2C through SparkFun’s Qwiic Connect System.

The SparkFun ZED-F9R GPS-RTK Dead Reckoning pHAT features the same high precision, sensor fusion GNSS board and impressive configuration options as the SparkFun ZED-F9R GPS-RTK Dead Reckoning Breakout, but with the ability for users to attach the pHAT to their Raspberry Pi (not included) to start navigating. No soldering is required to stack the pHAT on any single board computer with the 2x20 form factor.
