REVOLUTIONARY LASER SURVEYING TECHNOLOGY
8 MP + 2 MP cameras with a 91° field of view
​
The i85's integrated laser rangefinder captures survey-grade 3D coordinates from hard-to-reach points with exceptional precision. Combined with green laser technology and 8MP camera edge computing processing, laser aiming efficiency is boosted by 50%. This revolutionary approach enables accurate measurements of points that are otherwise inaccessible, expanding your reach without sacrificing accuracy.
ADVANCED GNSS SIGNAL TRACKING
Powered by iStar2.0 algorithm with ionospheric interference rejection
The i85 supports GPS, GLONASS, Galileo, and BeiDou constellations, ensuring robust signal tracking in challenging environments. With 96% fix reliability in low-latitude regions affected by solar activity, it maintains consistent performance where other receivers struggle. The advanced tracking technology delivers survey-grade accuracy in all conditions.


NEXT-GENERATION IMU TECHNOLOGY
200Hz IMU with automatic tilt compensation up to 60°
The 200Hz IMU supports automatic tilt compensation with no manual initialization required. The i85 maintains 3 cm accuracy within a 60° tilt range, delivering consistent results even in challenging positioning scenarios. This eliminates the challenge of measuring hidden or dangerous points while making survey work safer and more efficient.
ULTRA-COMPACT DESIGN
Extremely rugged 800g unit built for demanding field use
Built for demanding field use, the i85 combines all key components into a single compact 800g unit. It is IP68-rated for water and dust resistance and can withstand a 2-meter pole drop. The ultra-compact design makes it one of the most portable professional GNSS receivers available, reducing operator fatigue during extended field work.
