SparkFun GPS-RTK Dead Reckoning Breakout - ZED-F9R, SMA (Qwiic) 2X Qwiic Connectors Integrated SMA Connector for use with Antenna of Your Choice

The SparkFun Dead Reckoning Breakout SMA - ZED-F9R is a high precision, sensor fusion GPS board with equally impressive configuration options and takes advantage of u-blox's Automotive Dead Reckoning (ADR) technology. The ZED-F9R module provides a highly accurate and continuous position by fusing a 3D IMU sensor, wheel ticks, a vehicle dynamics model, correction data, and GNSS measurements. The ZED-F9R module is a 184-channel u-blox F9 engine GNSS receiver, meaning it can receive signals from the GPS, GLONASS, Galileo, and BeiDou constellations with ~0.2-meter accuracy! That's right; such accuracy can be achieved with an RTK navigation solution when used with a correction source. Note that the ZED-F9R can only operate as a rover, so you will need to connect to a base station. The module supports the concurrent reception of four GNSS systems. The combination of GNSS and integrated 3D sensor measurements on the ZED-F9R provide accurate, real-time positioning rates of up to 30Hz. This breakout maximizes position accuracy in dense cities or covered areas compared to other GPS modules. Even under poor signal conditions, continuous positioning is provided in urban environments and is also available during complete signal loss (e.g., short tunnels and parking garages). The ZED-F9R is the ultimate solution for autonomous robotic applications that require accurate positioning under challenging conditions.
