ZED-F9R-03B High Precision GNSS Module

u-blox has released a new firmware update that extends the range of positioning augmentation services supported by its ZED-F9R high precision GNSS dead reckoning modules. The new u-blox ZED-F9R-03B adds support for SPARTN 2.0 and QZSS CLAS correction services, extending the geographical market reach of the ZED-F9R and increasing the scalability of applications using the module. This RTK (Real-Time Kinematic) capable ZED-F9R module is designed for use in autonomous automotive and industrial applications that require simple and efficient implementation and typical applications of this module include slow-moving use cases such as robotic lawnmowers and shared e-scooters.

This module is based on the u-blox F9 multi-band GNSS receiver platform, which concurrently tracks up to four GNSS constellations, providing high-quality positioning accuracy. It has an integrated inertial measurement unit (IMU) for RTK positioning and employs sophisticated algorithms to fuse the IMU data with GNSS measurements, wheel ticks, correction service data, and a vehicle dynamics model to provide centimeter-level positioning accuracy even in situations where GNSS alone would fail.

Key Features of ZED-F9R Module

  • Multi-band GNSS receiver delivers centimeter-level accuracy

  • Fully integrated solution for fast time-to-market

  • Dynamic models for slow-moving service robots and electric scooters

  • SPARTN-format SSR corrections for easy and efficient implementation
