u-blox Unveils ZED-F9R-02B Positioning Module
Provides cm-level positioning accuracy for low-speed devices
Integration of GNSS correction data in the form of state-space corrections


On the 23rd, u-blox announced a firmware update for its 'ZED-F9R' positioning module, which provides centimeter-level positioning accuracy for low-speed applications such as e-scooters and shared bikes. The 'ZED-F9R-02B' is designed for autonomous driving and industrial applications that require accurate positioning data in challenging signal environments.
The ZED-F9R uses the u-blox F9 multi-band GNSS receiver platform to track up to four GNSS constellations simultaneously. It also uses Real-Time Kinematic (RTK) technology to derive centimeter-level position data.

High-precision GNSS measurements are fused with data collected by the module's inertial measurement unit (IMU), GNSS correction data, odometry information, and vehicle dynamic models to provide high-quality positioning accuracy in situations where GNSS alone might fail. It also includes dynamic models for lawn mower robots, electric scooters, cars, and more.

The ZED-F9R-02B integrates u-blox's GNSS correction data service, delivered in the form of highly scalable State-Space Corrections (SSR), accelerating the time-to-market of precision positioning solutions. It also supports a variety of correction services, including SPARTN, making GNSS correction data readily available across a wide range of geographic regions.
