u-blox has recently launched the X20 all-band GNSS module with an integrated L-band receiver that supports all available GNSS satellite signals (L1/L2/L5/L6) and can provide centimeter-level accuracy globally.
The module also includes PPP (Precise Point Positioning) correction on top of RTK (Real-time Kinematic) and features like end-to-end security functions, advanced jamming/spoofing detection, and other software features. These features make this device useful for industrial automation, automotive, UAVs, and ground robotics applications.
Multi-band GNSS receivers using L1, L2, L5, and the new L6/E6 band frequencies enhance accuracy, reliability, security, and other benefits. That includes better PNT (Positioning, Navigation and Timing) and RTK performance, access to global precise point positioning (PPP) services like Galileo HAS, faster convergence times in PPP for industrial and automotive use, and access to regional PPP services like MADOCA-PPP. Additionally, it helps comply with regional regulations like AIS-140 for NavIC in India and improves jamming and spoofing immunity through frequency diversity, particularly when combined with authentication services like Galileo OSNMA.
Back in 2021, u-blox launched the ZED-F9P RTK GNSS receiver which offered 1-3cm positioning accuracy with real-time kinematic (RTK) technology. The company mentions that the X20 all-band platform builds on it. It provides an alternative to the competing Quectel LG290P quad-band GNSS module (L1, L2, L5, and E6) unveiled last summer.
The X20 all-band GNSS module integrated the L-band GNSS receiver in a single chip which enhances the capabilities of the popular F9 module. The company also mentions that the X20 module is compatible with the F9 series for easy upgrades and new designs. In addition, it includes security features such as system authentication via secure boot and firmware updates, built-in secure Root of Trust for message encryption and authentication, along with anti-jamming and anti-spoofing capabilities. The company highlights a high update rate but doesn’t specify a numerical value for that.
X20 all-band GNSS module’s main benefits:
- Global centimeter-level accuracy in the shortest time
- Position availability, even in challenging environments
- Highest measurement quality that improves workflows
- Recognized brand in high-precision GNSS
- Adherence to the highest quality standards suitable for automotive use
- A comprehensive ecosystem with many partners for integrated solutions
- Highest technical specifications equivalent to geodetic-grade receivers
In terms of software, the company mentions ” The u-blox X20 platform is software upgradeable” and nothing more. Additionally, I couldn’t find much information about this module, including datasheets, specification sheets, or pricing information. But a bit more information can be found on their product page or press release.
