u-blox announces new dual-antenna, all-band GNSS heading module
u-blox has announced the launch of its all-band GNSS heading module, the ZED-X20D. Based on the u-blox all-band X20 high precision technology, the ZED-X20D is a breakthrough dual-antenna solution that delivers centimetre-level RTK positioning and precise, motion-independent GNSS-based heading.
The ZED-X20D delivers accurate heading even at standstill and low speeds, enabling more reliable auto-steering, safer autonomous operation, and more predictable behavior in real-world environments.
The compact, energy-efficient ZED-X20D targets industrial applications such as precision agriculture (including auto-steering and guidance systems), Unmanned Aerial Vehicles (agricultural UAVs, delivery 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. This approach maximises heading availability and stability and delivers best-in-class performance in challenging GNSS conditions.
To meet diverse positioning accuracy and deployment needs, the ZED-X20D supports RTK, PPP-RTK, and PPP correction services. Customers can use u-blox PointPerfect to access a portfolio 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 delivering centimetre-level positioning with accurate heading, simplifying design, reducing system cost, and accelerating mass adoption
Designed with u-blox end-to-end hardened security, the ZED-X20D protects heading and positioning data from satellite to host. It features secure boot, signed firmware, and a hardware root of trust for cryptographic material, supports Galileo OSNMA, and uses encrypted correction data. All-band frequency diversity and advanced interference monitoring provide robust protection against jamming and other threats, helping end customers maintain trustworthy operation in critical applications.
The ZED-X20D reduces system complexity and on-host processing requirements. Retaining the industry-proven ZED form factor offers an easy upgrade path for existing customers, including users of the ZED-F9P, ZED-F9H and ZED-X20P helping engineers to quickly evaluate, benchmark, and deploy the solution in new or existing designs.
