Main Features

Lightweight

Only 750g for efficiency and ease of everyday use.

Visual Surveying

Dual cameras extract survey-grade 3D coordinates improving point measurement efficiency.

Superior GNSS

Advanced ionospheric error mitigation with iStar 2.0

Auto-IMU

200 Hz Auto-IMU provides accurate measurements with pole tilt compensation.

Benefits and Performances

01 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.

02 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.

03 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.

04 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.

05 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.

06 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.
