The ZED-F9R Breakout and ZED-F9R pHAT each features u-blox's Automotive Dead Reckoning and allows for 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.
"SparkFun has always been proud of the GPS and GNSS boards we've made in-house," says Kirk Benell, SparkFun's Chief Technical Officer. "That makes us even more excited to be the first to develop not one, but two, open source development platforms that utilize u-blox's ZED-F9R module. We've created unique Real Time Kinematics (RTK) as well as dead reckoning boards in the past, but these are the first boards that combine the two features into a single professional platform."
The ZED-F9R GPS-RTK Dead Reckoning Breakout is a high precision, sensor fusion GNSS board that takes advantage of u-blox's Automotive Dead Reckoning (ADR) technology 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 GPS-RTK Dead Reckoning pHAT features the same high precision, sensor fusion GNSS board and configuration options as the 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.
Both boards are currently shipping.
