Qwiic GPS-RTK Dead Reckoning Breakout - GPS module with the ZED-F9K (SMA)

Description

GPS module with u-blox ZED-F9K system. Uses Automotive Dead Reckoning (ADR) technology. Provides a highly accurate and continuous position by combining the 3D IMU sensor, vehicle dynamics model, correction data and GNSS measurements. The ZED-F9K 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-F9K is an excellent solution for autonomous robots that require accurate positioning in difficult conditions.

The board has two Qwiic connectors and a USB Type-C connector for communication with the system. There are also pins on additional pins located on the edges of the board. Full documentation with examples of use is available on the product page.
