HIGHLIGHTS

The i89 is a compact visual GNSS receiver with a 1408-channel module, boosting RTK availability in challenging environments. Its CHCNAV iStar2.0 software uses advanced ionospheric modeling to deliver high-integrity RTK fix rates in solar-active regions. Visual surveying extracts accurate 3D coordinates from video, simplifying measurements in signal-obstructed, hard-to-reach or dangerous areas. Integrated AR visual navigation and stakeout improves efficiency by 50%. AUTO-IMU eliminates manual initialization to streamline field work. With 16.5 hours of battery life and a 1.65 lb lightweight design, it ensures optimal daily survey productivity.
