All-band GNSS receiver enables affordable cm-level precision
U-blox has launched the ZED-X20P all-band GNSS receiver module, which delivers global, centimeter-level location precision to the mass market at a total cost of up to 90% less than traditional options.
Designed for global use at scale, the GNSS receiver can receive concurrent signals on the L1, L2, L5, and L6 bands from four global GNSS constellations, as well as SBAS, QZSS, and NavIC.
The receiver module leverages u-blox’s extensive GNSS expertise to overcome the technological and cost barriers, making worldwide centimetre-level navigation capabilities accessible for a variety of applications for the first time.
The compact and highly energy-efficient ZED-X20P is primarily targeted at the industrial sector, which includes smart construction, surveying, precision agriculture, rail, maritime, mining, and deformation monitoring. Other potential use cases include unmanned aerial vehicles (UAVs), ground robotics, delivery robots, smart cities, and virtual reality.
To achieve high-precision positional information, the ZED-X20P is compatible with various GNSS correction services, including those provided via satellite through L-band, without the need for extra hardware. Customers can opt for u-blox’s PointPerfect, which delivers a full range of PPP-RTK, network RTK, and global PPP correction services for robust performance and scalability in mass markets. The module also includes built-in support for Galileo E6, allowing customers access to the free-to-use Galileo High Accuracy Service (HAS), along with any standard-compliant RTK service, including both free and commercial options, for maximum flexibility.
When paired with an all-band antenna such as the u-blox ANN-MB2, the ZED-X20P GNSS receiver ensures optimal results, combining ease of use with superior compatibility. Together, they create a one-stop-shop solution for achieving affordable high precision across a diverse array of applications.
Further, the GNSS receiver module is designed with end-to-end security to safeguard the navigation information the host equipment receives by protecting one of the most important sensors in the end device.
Security measures include a secure boot and signed firmware to prevent tampering and a built-in root of trust for securely storing cryptographic material. The module supports Galileo OSNMA (Open Service Navigation Message Authentication) and uses encrypted correction data to enhance security further. It features all-band frequency diversity, which provides robust protection against jamming. Additionally, all communications between the module and the host are encrypted and authenticated, ensuring secure data transfer.
The ZED-X20P is also designed for ease of integration into new and existing products. Combining all positioning functionality into a single compact module that incorporates the all-band receiver chip and correction data processing eliminates the need for additional receivers or on-host processing. Moreover, by retaining the popular ZED form factor, the module offers an easy upgrade path for existing customers, including those using the ZED-F9P.
Stephan Zizala, CEO of u-blox, elaborated: “Customers can now start working with our new ZED-X20P module, which integrates a unique combination of u-blox GNSS single chip, firmware, and correction service within a module. It enables trustworthy centimeter-level positioning around the globe. Applications like mobile robots, precision agriculture, and automated construction machines will benefit from superior performance at a significantly lower cost than more traditional solutions.”
