u-blox ZED-F9R GNSS Modules with an F9 multi-band GNSS receiver features rapid convergence time within seconds. This module combines high precision positioning with the highest availability by making use of all four GNSS constellations simultaneously. The ZED-F9R sensor fusion modules with an integrated Inertial Measurement Unit (IMU) are capable of high precision positioning. The sophisticated built-in algorithms fuse the IMU data, GNSS measurements, wheel ticks, and a dedicated dynamic model to provide a high-accurate positioning. The ZED-F9R modules support a range of correction services allowing each application to optimize performance according to the various application needs. This sensor module is designed to perform in difficult multipath environments and modern autonomous robotics applications.
