October 3, 2025 /SemiMedia/ — u-blox has introduced the ANN-MB3, a compact triple-band RTK antenna supporting L1, L2, and L5 frequencies, designed for the F20 high-precision GNSS platform and compatible with F9 receivers. The antenna measures 62 × 80 × 25.5 mm and delivers robust high-precision positioning, while offering simplified integration and cost efficiency for industrial, automotive, and robotics applications.

The ANN-MB3 incorporates an LTE B13 notch filter in the L1 RF path to mitigate out-of-band interference, ensuring stable performance in challenging RF environments. The antenna supports flexible installation and is ready for immediate use, reducing development time, cost, and the need for specialized RF expertise.

Engineered for mass adoption, the ANN-MB3 provides practical centimeter-level positioning for applications including industrial automation, agriculture, autonomous vehicles, mobile robotics, UAVs, and network infrastructure.This launch extends u-blox’s high-precision antenna portfolio, which includes the dual-band ANN-MB series (L1/L2), ANN-MB1 (L1/L5), and the all-band ANN-MB2, offering customers flexibility to match performance, cost, and integration requirements. Engineering samples of the ANN-MB3 will be available starting October 2025.
