CHCNAV i76 Palm-Sized Visual IMU-RTK GNSS Receiver

The CHCNAV i76 Palm-Sized Visual IMU-RTK GNSS Receiver is a lightweight, durable, and highly efficient tool designed to enhance project stakeout efficiency and accuracy. With integrated GNSS, IMU RTK, dual cameras, CAD+AR visual stakeout, and IP68 protection, the i76 is built to perform in the most challenging field conditions.

Key Features:

Enhanced Stakeout Efficiency: CAD+AR visualization improves project stakeout efficiency by up to 40%.
Ultra-IMU Technology: 5th Gen IMU with EKF algorithms for optimal measurement accuracy, including automatic pole tilt compensation within 3 cm at a 60° tilt.
Advanced Antenna & GNSS Engine: 4th Gen air-medium GNSS antenna and hybrid GNSS engine with iStar 2.0 technology, achieving an RTK fix rate of over 96% in solar-active regions.
Compact & Durable Design: Weighs only 450g, with IP68 protection, 2-meter drop resistance, and biomimetic structure for durability.
Integrated Dual Cameras: 95° wide-angle dual cameras for enhanced visual stakeout.
Long Battery Life: Over 17 hours of continuous operation with an energy-efficient lithium battery.
Seamless Connectivity: Intelligent cloud-based OTA upgrades and robust GNSS signal tracking in all constellations and frequencies.

The i76 Palm-Sized Visual IMU-RTK GNSS receiver is engineered to provide high precision and user-friendliness in diverse and challenging conditions. By integrating advanced GNSS, IMU, AR, and MR technologies, the i76 delivers a comprehensive and intuitive view of site layouts, improving path planning, minimizing detours, and simplifying tasks like pipeline direction anticipation and foundation building.

The i76’s 5th Gen Ultra-IMU technology operates at 200 Hz, boosted by EKF algorithms to maintain accuracy within 3 cm even at a 60° tilt. The device features a “poke-and-measure” capability, eliminating the need for manual IMU initialization or bubble centering, making it user-friendly and efficient.

Equipped with a 4th Gen air-medium GNSS antenna and hybrid GNSS engine, the i76 excels in challenging environments, achieving a high RTK fix rate and extending UHF coverage up to 25 km in standard conditions. Its compact and rugged design, combined with intelligent cloud-based OTA upgrades and a robust battery, ensures reliability and extended endurance for professionals in surveying, construction, and mapping.
