The MK43 is a high-performance concurrent GNSS receiver capable of tracking multiple systems simultaneously. With its advanced multi-band RF front-end, it supports GPS, GLONASS, BDS, and QZSS. By processing all visible satellites with correction data, it delivers precise RTK navigation. Powered by the MK43 engine, it offers exceptional sensitivity, rapid acquisition, and strong interference suppression, ensuring highly reliable positioning and navigation even in challenging environments.
