GNSS Sensors
A compact and lightweight device that combines GNSS, IMU RTK, dual cameras, and CAD+AR visual stakeout. Featuring IP68 protection and 2-meter drop resistance, this tool is designed to enhance efficiency and durability in the field.
EFFICIENT CAD AR STAKEOUT
Enhance project stakeout efficiency by up to 40%
The i76 boosts stakeout efficiency in construction projects by 40% in comparison to traditional surveying methods by integrating CAD base maps with augmented reality (AR) visualization, utilizing GNSS, IMU, AR, and mixed reality (MR) technologies. This offers a comprehensive and intuitive view of site layouts, aiding path planning, minimizing detours, and simplifying tasks like pipeline direction anticipation and foundation building. The AR overlay is particularly valuable for redline reviews, centerline verifications, and optimization of stakeout operations in diverse construction scenarios.
ULTRA-IMU TECHNOLOGY
Boost Accuracy by 30%
The i76 integrates a 5th Gen interference-free Ultra IMU operating at 200 Hz, enhanced by EKF algorithms for optimal measurement accuracy. It includes automatic pole tilt compensation, maintaining accuracy within 3 centimeters even at a 60-degree tilt, and ensuring reliable and user-friendly tilt measurements. The device simplifies operations with its “poke-and-measure” feature, eliminating manual IMU initialization or bubble centering. The IMU functions regardless of the range pole’s position, whether handheld, shoulder-mounted, or placed horizontally.
AIR-MEDIUM ANTENNA & HYBRID GNSS ENGINE
Achieve an RTK fix rate of over 96% in solar active regions
The i76 GNSS excels in solar-active and other challenging environments with its 4th Gen air-medium GNSS antenna and hybrid GNSS engine, offering robust tracking of all GNSS constellations and resistance to interference. Enhanced by iStar 2.0 technology, it achieves an RTK fix rate of over 96%, which is ideal for areas with high ionospheric activity. Pairing with CHCNAV base stations, it extends UHF coverage up to 25 km in standard conditions and 5-8 km in areas with obstructed signals, ensuring high-quality data in diverse surveying scenarios.
