The u-blox ANN-MB2 multi-band (L1/L2/L5/E6/B3/L) active GNSS antenna is designed to reduce time-to-market for modern wide-frequency, multi-constellation, high precision GNSS applications.
These require centimeter-level accuracy and a reliable RTK positioning fix even in challenging environments. Its robust design, excellent price-toperformance ratio, and flexible mounting options make the ANN-MB2 an ideal choice for mass market applications requiring an all-band high precision GNSS antenna.
The ANN-MB2 is a perfect match to the u-blox all-band X20 high precision platform (e.g. ZED-X20P), and the u-blox F9 high precision products that support L1, L2, and L5 bands along with the L-band for RTK corrections.
With ANN-MB2, customers have a reliable, ready-to-use all-band antenna that streamlines evaluation, minimizes design efforts, and speeds up mass adoption.
