u-blox has expanded its ZED-X20P platform with the ZED-X20P-01B, a GNSS module variant that adds global Precise Point Positioning through Galileo High Accuracy Service. It gives OEMs a way to build decimeter-level positioning into products shipped across regions where local RTK infrastructure may be unavailable, inconsistent, or impractical.
The ZED-X20P-01B is a multi-band GNSS module used for high-precision positioning in embedded navigation, tracking, mapping, and autonomous systems. On the board, the module forms part of the GNSS positioning chain, taking in satellite signals and correction data before the system uses that location output for navigation, tracking, mapping, or control.
Galileo HAS Brings PPP To Global Deployments
Support for Galileo High Accuracy Service allows the module to use satellite-delivered correction data for PPP operation. That gives developers another option when RTK networks, SBAS coverage, or reliable communications are not always available. For OEMs shipping products internationally, this avoids having to plan each deployment around regional correction services. A UAV, marine system, agricultural machine, or mapping device can be designed once and used across different environments without changing the positioning approach.
The module remains compatible with u-blox PointPerfect services, so other correction methods can still be used where they fit the application.
Decimeter-Level Accuracy For Remote Systems
The ZED-X20P-01B is designed to deliver positioning accuracy in the decimeter range when PPP corrections are available. That level of precision suits applications where standard GNSS is not enough but where setting up local infrastructure is not practical. Typical use cases include UAV navigation, marine positioning, seabed mapping, precision agriculture, construction, mining, and environmental surveying. These are all areas where systems are expected to operate away from fixed infrastructure and still maintain usable positioning data.
There is also a deployment consideration here. Systems moving between sites, countries, or connectivity conditions need a positioning approach that does not depend on a single correction source.
Moving Base Support For Relative Positioning
The module includes Moving Base functionality, allowing one receiver to act as a reference for another. This supports relative positioning between systems that are both in motion. In robotics, autonomous machines, and coordinated vehicles, this allows systems to measure position relative to each other rather than relying only on absolute coordinates. It reduces the need for fixed reference points in those designs.
Better Resilience Against Jamming And Spoofing
u-blox has added stronger jamming and spoofing detection and mitigation, with validation carried out at Jammertest 2025. GNSS interference is a practical concern in many deployments. Systems operating in urban areas, industrial environments, or mission-critical outdoor applications need to handle degraded or manipulated signals without reporting misleading position data.
ZED Form Factor Keeps Integration Familiar
The ZED-X20P-01B keeps the established ZED form factor, making it easier to use in existing designs based on the same platform. For current ZED-X20P users, this offers a straightforward upgrade path. The module is intended for systems such as UAVs, marine navigation equipment, precision agriculture platforms, construction machinery, and autonomous systems operating across multiple regions.
