Product description: SparkFun GPS-RTK Dead Reckoning Kit - GPS module with ZED-F9R chip and SMA antenna - SparkFun KIT-23452
SparkFun GPS module with u-blox ZED-F9R chip using Automotive Dead Reckoning (ADR) technology. Using sensor fusion technology, it provides incredible accuracy by combining GNSS measurements, 3D IMU data, wheel signals and vehicle dynamics model. The kit supports simultaneous reception of four GNSS systems: GPS , GLONASS, Galileo and BeiDou , guaranteeing positioning with an accuracy of 0.1 m using RTK correction. Maintains precise positioning even in places with weak GNSS signal, such as tunnels, cities or underground parking lots. ZED-F9R works in "rover" mode, so it requires connection to an RTK base . The kit also includes a multi-band GNSS antenna with a magnetic base and a USB A to USB C cable for easy connection and installation.
The manufacturer has prepared a detailed user guide that will help you get started with the module. Check it out!
