u-blox X20D dual antenna high-precision GNSS platform

u-blox, has announced its latest all-band GNSS heading module, the ZED-X20D. Based on the u-blox all-band X20 technology, the ZED-X20D is a dual-antenna solution that is designed to deliver centimetre-level RTK positioning and precise, motion-independent GNSS-based heading.

The company says the ZED-X20D delivers accurate heading even at standstill and low speeds, enabling more reliable auto-steering, safer autonomous operation, and more predictable behaviour in real-world environments.

The compact, energy-efficient ZED-X20D targets industrial applications such as precision agriculture (including auto-steering and guidance systems), UAVs, heavy machinery, marine and robotics navigation. It supports all GNSS constellations on L1, L2, L5, and L6 on both antennas, as well as L-band. The ‘all bands on both antennas’ approach maximises heading availability and stability and provides improved performance in challenging GNSS conditions.

To meet diverse positioning accuracy and deployment needs, the ZED-X20D supports RTK, PPP-RTK, and PPP correction services. Users can use u-blox PointPerfect to access a comprehensive range of correction options for regional and global coverage, while built-in support for Galileo E6 enables the free-to-use Galileo High Accuracy Service (HAS).

ZED-X20D, together with the u-blox ANN-MB2 all-band high-precision antenna and u-blox PointPerfect service, forms a ready-to-use all-band GNSS solution with centimetre-level positioning with accurate heading, simplifying design, reducing system cost, and accelerating mass adoption.
