A new L1/L2/L5 antenna combining excellent performance-price ratio, robust design, and compact form factor – making high-precision positioning more accessible for mass adoption.
u-blox has announced the launch of the ANN-MB3, its latest L1/L2/L5 triple-band RTK antenna. Designed for the u-blox F20 high precision platform and optimized for seamless integration, the ANN-MB3 delivers exceptional performance at an affordable price point. By offering a robust antenna suitable for mass adoption, u-blox is addressing the industry’s growing demand for a reliable, flexible, and cost-effective GNSS antenna solution that accelerates the adoption of high-precision positioning technologies across industrial, automotive, and robotics applications.
Performance-price ratio for real-world adoption
The ANN-MB3 is engineered to deliver validated high performance at reasonable cost, providing customers with a practical and scalable way to integrate high-precision positioning into their products. By combining robust design and compact dimensions (62 × 80 × 25.5 mm), the antenna makes high-precision GNSS accessible for a wide range of industries and applications.
Flexible, reliable, and easy to integrate
The ANN-MB3 integrates an additional notch filter (LTE B13) in L1 RF path, provides the best possible out-of-band interference mitigation, ensuring reliable performance even in harsh RF environments while minimizing design complexity for customers. Ready-to-use and designed with flexible installation options, ANN-MB3 reduces the time, cost, and RF expertise required to implement triple-band GNSS solutions.
Optimized for the u-blox F20 triple-band platform (e.g. ZED-F20P) and fully compatible with u-blox F9 receivers supporting L1, L2, and L5 bands, ANN-MB3 enables customers to standardize on a single antenna solution that covers multiple frequency needs.
Enabling mass adoption of high-precision positioning
Applications such as industrial automation, agriculture, heavy machinery, autonomous vehicles, mobile robotics, UAVs, and network infrastructureincreasingly require robust centimeter-level positioning. The streamlined and affordable ANN-MB3 provides a practical way to meet these demands at scale, bridging the gap between performance and cost that has historically limited market adoption.
Extending the u-blox high-precision antenna portfolio
With ANN-MB3, u-blox now offers the industry a complete range of best-in-class high precision external active GNSS patch antennas:
- ANN-MB series (L1/L2) – dual-band
- ANN-MB1 (L1/L5) – dual-band
- ANN-MB2 – all-band solution
- New ANN-MB3 (L1/L2/L5) – triple-band solution
This portfolio provides customers with maximum flexibility to select the antenna that best matches their performance, cost, and integration requirements.
