U blox ZED F9R GNSS module

     U-blox released the latest firmware of the ZED-F9R high-precision GNSS (Global Navigation Satellite System) inertial navigation module to expand its range of enhanced positioning services. After the implementation of firmware update, u-blox ZED-F9R-03B will support SPARTN 2.0 and QZSS CLAS calibration services, expand the market coverage of ZED-F9R module applications, and improve the scalability of applications.

     For today's autonomous vehicle and industrial applications, easy and efficient implementation process and fast access to high-precision positioning data are crucial, even in densely populated cities and other signal constrained environments. The ZED-F9R module supporting RTK (real-time dynamic) function can just meet the needs of these applications. Common applications include slow moving usage scenarios, such as automatic mowers and shared electric scooters.

     ZED-F9R module integrates inertial measurement unit (IMU) that supports RTK positioning. Its advanced built-in algorithm integrates IMU data, GNSS measurement, wheel speed pulse, correction service data and vehicle dynamics model, which can provide centimeter level positioning accuracy even if GNSS signal is lost in a short time. Based on the u-blox F9 multi frequency GNSS platform, ZED-F9R module can track up to four GNSS constellations at the same time, thus providing high-quality positioning accuracy.

     "Our new ZED-F9R-03B high-precision GNSS module supports SPARTN 2.0 and QZSS CLAS, so designers can promote high-precision solutions that require inertial navigation technology to a wider range of regions, thus improving the scale efficiency of the product. u-blox also launched PointPerfect service, which can provide correction data based on SPARTN protocol."—— Alex Ngi, product manager of industrial navigation and robot of u-blox positioning product center
