HIGH-PERFORMANCE GNSS ON TOP LASER

The i85 Laser IMU GNSS is a compact, 800 g receiver designed for demanding fieldwork. Equipped with a 1408-channel GNSS chip and CHCNAV’s iStar2.0 engine, it delivers consistent RTK performance, even in challenging conditions. Advanced ionospheric modeling maintains fix reliability during periods of increased solar activity.

The built-in laser module enables fast, accurate 3D point capture in obstructed or hard-to-reach areas. AUTO-IMU eliminates manual centering, allowing immediate measurements with tilt compensation. Combined with a high-speed SoC processor and next-generation IMU,the i85 enhances laser-based surveys.

With up to 20 hours of battery life and features such as AR navigation and visual stakeout, the i85 is built for efficiency across all experience levels.

WORLD LEADER IN GNSS

Equipped with CHCNAV’s multi-constellation, multi-frequency GNSS chip and proprietary iStar2.0 technology, the i85 delivers consistent, ultra-accurate positioning even in complex environments. It features an enhanced IMU that optimizes heading accuracy, enabling laser measurements accurate to 2 cm at 5 m and 3 cm at 10 m*. Its reinforced metal chassis and integrated all-in-one design ensure stable laser sensor alignment. Multi-sensor synchronization reduces latency and enhances calculation accuracy. An integrated temperature sensor adjusts measurement algorithms in response to environmental changes, while intelligent gain control adapts to lighting and signal conditions to ensure consistent laser measurement performance.

BRIGHT GREEN LASER
The i85 is equipped with an industrial-grade green laser that maintains high visibility across a wide range of surfaces. Resistant to ambient light levels up to 50,000 lux, comparable to direct midday sunlight, the laser remains clearly visible, allowing accurate targeting even under bright outdoor conditions.
Optimal visibility on all surfaces

CLEAR LONG-RANGE SHOTS

With the industry’s first true 8MP high-definition camera, the i85 offers precise visual targeting over long distances. The integrated camera functions like a high-definition telescope, keeping distant targets crisp and clearly defined even when zoomed in. Users can confidently aim and capture targeted points without interference from visual distortion or blurry images.

LASER MEASUREMENT WITH EXTENDED RANGE

The i85 overcomes GNSS signal limitations in obstructed environments such as under dense foliage or near tall structures through a hybrid GNSS and laser ranging solution. Its integrated high-precision laser enables accurate data collection in areas that are physically difficult or unsafe to access. Data acquisition efficiency improves by more than 50%, reducing collection time from minutes to seconds. Whether surveying across rivers, behind barriers, or near hazardous zones, surveyors can collect data remotely without direct exposure to risk. The i85 enables safe, efficient, and accurate measurement even under the most challenging field conditions.

SMART AUTO-FOCUS

The i85’s high-performance embedded processor powers real-time image processing, ensuring clear views with ultra-low latency. It automatically adjusts focus and zoom based on user behavior, and after a brief aiming period, the device assists in capturing point data without requiring manual input. The intelligent autofocus feature streamlines operation and minimizes handling, enabling greater productivity.
