u-blox now offers a new firmware update which extends the range of positioning augmentation services supported by its ZED-F9R high precision GNSS dead reckoning modules. Thanks to a firmware update, the ZED-F9R-03B adds support for SPARTN 2.0 and QZSS CLAS correction services, expanding the geographical market reach of the devices and increasing the scalability of applications employing the module.

The RTK-capable module was developed for autonomous automotive and industrial applications needing simple and efficient implementation and where rapid access to highly accurate positioning data is essential, even in challenging signal environments such as in dense cities. Typical applications incorporate slow-moving use cases such as robotic lawnmowers and shared e-scooters.

The module has an integrated IMU for RTK positioning and employs sophisticated algorithms to fuse the IMU data with GNSS measurements, correction service data, wheel ticks, and a vehicle dynamics model to deliver centimetre-level positioning accuracy even in situations where GNSS alone would fail. It is based on the company's F9 multi-band GNSS receiver platform, which concurrently tracks up to four GNSS constellations, offering high-quality positioning accuracy.

“As our new ZED-F9R-03B high precision GNSS module also supports SPARTN 2.0 and QZSS CLAS, it enables designers to bring products that need dead reckoning technology to wider geographical markets, increasing economies of scale. PointPerfect is delivers correction data based on the SPARTN protocol, a service that is available from u-blox,” says Alex Ngi, product manager, Industrial Navigation and Robotics, Product Center Positioning at u-blox.
