u-blox X20 all-band, high-precision GNSS platform

u-blox’s X20 all-band, high-precision GNSS platform builds on the company’s F9 high-precision GNSS platform, with improvements in accuracy, performance and security. This latest generation addresses the current high-precision GNSS needs around the world, with a futureproof design that is equipped to handle new and emerging technologies and standards. The platform is designed for industrial automation, automotive and other applications that require centimetre-level position accuracy in challenging environments, as well as time synchronisation applications for critical infrastructure systems.

The all-band (L1/L2/L5/L6) platform features an integrated L-band receiver. As it includes all available GNSS satellite signals, it offers high-precision positioning even in difficult signal environments. It supports the basic L1 and L2 frequencies, along with the subsequently added L5 band. The L5 band operates at lower frequencies than the L1 and L2 bands and benefits from improved signal properties, making L5 signals inherently more robust. The product also adds support for the L6 band, used for navigation services as well as correction services that help make positioning estimations more precise.

The platform provides flexibility, with built-in support for all types of correction services. It not only supports local base stations and correction types such as RTK (real-time kinematic), Network RTK and PPP-RTK, but also introduces the option to utilise PPP (precise point positioning) corrections. The platform’s versatility and scalability allow its users to select the optimal solution for their application. Potential applications are manifold, from port logistics operations to machine control in construction as well as emerging industrial applications, for instance UAVs, and ground robotics such as lawnmowers.

The platform is software upgradeable, meaning users will be able to adapt their system should there be any evolutions in the relevant technologies and standards. It also comes with end-to-end security functions, including system authentication via secure boot and secure firmware update, message authentication and encryption with built-in secure root of trust (RoT). It supports Galileo OSNMA authentication combined with advanced jamming and spoofing detection and mitigation.
