i93 Visual GNSS Receiver

CHCNAV i93 – Advanced Visual IMU-RTK GNSS Receiver

The CHCNAV i93 GNSS Receiver is a cutting-edge visual IMU-RTK surveying and engineering solution, designed to enhance precision, efficiency, and ease of use. By integrating advanced GNSS, IMU, and dual-camera technologies, the i93 revolutionizes traditional surveying workflows. With 3D visual stakeout, video-photogrammetry, and automated IMU calibration, it allows surveyors to achieve faster, more accurate results in even the most challenging environments.

Key Features:

✔ High-Precision GNSS Performance – Utilizing multi-constellation tracking and CHCNAV's iStar GNSS RTK algorithm, the i93 ensures consistent, survey-grade accuracy even in areas with limited satellite visibility. Its hybrid engine improves positioning performance, delivering high-quality RTK data for construction sites, infrastructure projects, and geospatial applications.

✔ 3D Visual Survey & Stakeout – The dual-camera system enables real-time visual navigation, allowing operators to see and stake out points more efficiently. The intuitive LandStar software provides a clear, 3D visual experience with a directional arrow and distance indicators, simplifying stakeout and increasing productivity.

✔ Video-Photogrammetry for Hard-to-Reach Points – With video-based point measurement, surveyors can capture precise 3D coordinates from video footage, making it possible to survey hazardous, obstructed, or otherwise inaccessible locations. This feature eliminates the need for manual access, improving both safety and efficiency.

✔ Auto-IMU for Seamless Operation – The 200 Hz automatic IMU tilt compensation ensures instant initialization with no manual calibration required. Operators can measure and stake out with high accuracy even when tilting the pole up to 60 degrees, improving speed and flexibility in the field.

✔ Long-Lasting Performance & Rugged Build – Designed for demanding field conditions, the i93 is housed in a shock-resistant magnesium alloy body with IP67 dust and water protection. A long-lasting battery provides up to 34 hours of continuous operation, eliminating downtime.

✔ Reliable Connectivity & Versatile Applications – Equipped with Wi-Fi, Bluetooth, NFC, 4G LTE, and UHF modems, the i93 supports seamless communication with controllers and cloud-based workflows. Whether working as an RTK network rover, base station, or in PPK mode, the i93 adapts to diverse surveying and mapping applications.
