Positioning expert u-blox has released a firmware update that expands the range of positioning augmentation services supported by its high-precision ZED-F9R GNSS (Global Navigation Satellite System) dead reckoning modules. Thanks to a firmware update, u-blox’ ZED-F9R-03B now supports SPARTN 2.0 and QZSS CLAS correction services. This extends the geographic market reach of the ZED-F9R and increases the scalability of applications using the module.

The 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 where fast access to highly accurate position data is critical – even in challenging signal environments such as dense cities (“urban canyons”). Typical applications include slow-moving use cases such as e-scooters.

The module features an integrated inertial measurement unit (IMU) for RTK positioning and uses sophisticated algorithms to fuse IMU data with GNSS measurements, wheel ticks, data from correction services, and a model of vehicle dynamics to provide centimeter-accurate positioning even in situations where GNSS alone would fail. The system is based on the u-blox F9 multiband GNSS receiver platform, which simultaneously tracks up to four GNSS constellations to provide high positioning accuracy.

“Because our new ZED-F9R-03B high-precision GNSS module also supports SPARTN 2.0 and QZSS CLAS, it enables developers to bring products that require dead reckoning technology to broader geographic markets to achieve economies of scale. PointPerfect provides correction data based on the SPARTN protocol, a service offered by u-blox,” said Alex Ngi, Product Manager, Industrial Navigation and Robotics, Product Center Positioning at u-blox.
