Swiss firm U-Blox has enhanced spoofing and jamming protection with a Galileo OSNMA firmware update for its Zed-F9P GNSS module.

The OSNMA (open service navigation message authentication) firmware update advances the spoofing and jamming detection capabilities of the multi-band GNSS module. It ensures robust and reliable performance for various applications such as robotic lawnmowers, unmanned aerial vehicles, surveying and mapping.

The ZED-F9P-05B (www.u-blox.com/en/product/zed-f9p-module) is the first U-Blox product to adopt OSNMA (www.u-blox.com/en/technologies/osnma-galileo-spoofing), a cryptographically strong solution to spoofing problems, setting a standard in the industry for GNSS security and reliability.

The update helps ensure the performance of the ZED-F9P-05B. Features include enhanced spoofing and jamming detection to guarantee end-product robustness against tampering and malicious attacks, as well as improved real-time kinematic (RTK) convergence to reduce the risk of incorrect readings important to surveying-related applications.

The addition of the SpartN (www.spartnformat.org) Beidou satellite constellation support also enhances the capabilities of the GNSS receivers and boosts the performance of the U-Blox PointPerfect GNSS correction service in some regions. As the receivers feature an ionospheric model, they deliver a more robust performance during periods of elevated ionospheric activities.
