Best GNSS Performance
The i89 achieves unrivalled GNSS performance - the iStar2.0 algorithm and ionospheric interference rejection technology provide a 96% reliable fix rate in low latitude regions with high solar activity.
Visual Survey Excellence
Accurately measure previously inaccessible points with the i89's vision surveying capabilities. Panoramic capture mode with 85% overlap with integrated IMU data significantly improves point measurement performance.
AR Visual Navigation and Stakeout
Simplify field operations with the i89's AR visual navigation and stakeout features that save up to 50% of the operator's time, even for less experienced users, with a reliability that is 10 times greater than standard gyroscope-based GNSS.
Efficient 3D Modeling
Seamlessly create 3D models using the i89's video photogrammetry algorithms. Compatibility with industry-standard 3D modelling software ensures flexibility and convenience.
Auto-IMU Technology
The i89's built-in 200Hz Auto-IMU removes the need for manual initialization, ensuring efficiency with every measurement. Its automatic pole tilt compensation maintains 3cm accuracy over a 60-degree tilt range.
Compact and Durable Design
The i89 pocket-sized design (750g) integrates GNSS, IMU and dual cameras into a single compact unit. IP68-rated for durability and reliable performance in a variety of field conditions, the i89 can withstand a 2 meter pole drop
