The MK43 is a concurrent multi-GNSS smart antenna supporting GPS, GLONASS, BDS, and QZSS reception. Its multi-band RF architecture processes all visible satellites for RTK positioning with correction data. The high-performance MK43 engine delivers high sensitivity, fast acquisition, and robust interference suppression for reliable navigation in challenging environments.
