Pole Tilt Compensation
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.

Portable and Lightweight
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.

Professional GNSS
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.

Rugged Design
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.
