GPS-RTK Dead Reckoning pHAT - GPS module for Raspberry Pi

Description

GPS module with u-blox ZED-F9R. The module uses Automotive Dead Reckoning (ADR) technology. Provides highly accurate and continuous positioning by combining the 3D IMU sensor, vehicle dynamics model, correction data and GNSS measurements. The ZED-F9R module can receive signals from the GPS, GLONASS, Galileo and BeiDou constellations with an accuracy of 0.2 meters (supports simultaneous reception of four GNSS systems). The module provides position accuracy in cities or in covered areas. Continuous positioning is ensured even under weak signal conditions and is available in the event of total signal loss (e.g. short tunnels and garages). The ZED-F9R is an excellent solution for autonomous robots that require accurate positioning in difficult conditions.

The module has a 40-pin GPIO connector compatible with Raspberry Pi, NVIDIA Jetson Nano or Google Coral. The board also has a Qwiic connector and a USB Type-C connector for communication with the system.
