The JS-AUK45G-9 is a high-performance concurrent GNSS receiver designed to track multiple systems simultaneously. With its advanced multi-band RF front-end, it supports all major constellations including GPS, QZSS, SBAS, GLONASS, Galileo, and BDS. By processing all satellites in view with correction data, it delivers precise RTK navigation. Powered by the JS-AUK45G-9 engine, it provides exceptional sensitivity, rapid acquisition, and strong interference suppression, ensuring reliable positioning even in challenging environments.
