Visual survey with video-photogrammetry technology enables accurate point measurements and access to previously hard-to reach, signal obstructed, and hazardous points. The i93 GNSS can be used to complement aerial surveys generated from oblique imagery since its data is compatible with the most popular 3D modeling software. The i93  GNSS receiver is powered by the innovative CHCNAV iStar GNSS RTK algorithm, multi-band GNSS channels, and hybrid engine for reliable, high accuracy positioning in even the most challenging site conditions. The Auto-IMU of  i93 features automatic initialization, eliminating the hassle of manual initialization and simplifying surveying operations in the field. The i93 is the ideal solution for completing tasks faster, more accurately, and more efficiently

1408-CHANNEL GNSS, iSTAR TECH AND HYBRID ENGINE

Enhanced GNSS RTK performance in challenging environments
The i93 GNSS receiver features 1408 channels tracking full constellations and frequencies, powered by an integrated RF-SoC processor and iStar CHCNAV technology. It delivers reliable and accurate positioning data, with a 15% gain in survey-grade GNSS RTK performance. The built-in hybrid engine and narrowband interference mitigation boost GNSS dataquality and signal tracking capabilities by over 20% for optimal RTK performance.

VISUAL NAVIGATION AND STAKEOUT

Effortless one-step stakeout at a glance
The i93 integrates star-level cameras to provide an immersive 3D visual navigation and stakeout experience. With LandStar™ software’s 3D visual view, surveyors are guided by a clear, eye-catching directional arrow  and real-time distance, and the stakeout point markeddirectly on the ground in the 3D visual view. Moreover, 3D visual capabilities are also available for line stakeout and CAD-based map stakeout, making operations similarly effortless, intuitive, and efficient. This simplifiesthe stakeout process, allowing for quick completion in seconds and increasing efficiency by up to 50% for less experienced field operators

VISUAL SURVEY AND 3D MODELING

Accuracy comes into view: Measure any point with ease
The i93 Visual RTK combines GNSS, IMU and premium global shutter camera with video photogrammetry technology, delivering survey-grade 3D coordinates from real-world video in seconds. It is easy to survey previously hard-to- reach, signal-obstructed and hazardous points in the field, with dynamic panoramic video capture and automatic image matching that improves productivity by up to 60%. Automatic highspeed continuous shooting with up to 85% overlap ensures high processing success. Surveyors looking for ease, speed and accuracy will find the i93 Visual RTK an ideal tool.

ENGINEERED FOR VERSATILE FIELD USE

Uninterrupted operation in any RTK modes
The i93 Visual RTK has all the connectivity features a surveyor needs to complete any GNSS survey project scenario. Built-in Wi-Fi, Bluetooth and NFC technologiesallow for seamless connection to field data controllers and tablets. Integrated 4G and UHF modems support all GNSS survey modes. Smart power management ensures up to 34 hours of operation as a GNSS RTK network rover and eliminates the need for spare or external batteries. No matter where or when, the i93 GNSS magnesium alloy body is shock, dust and water resistant to ensure uninterrupted performance.

FAST, RELIABLE INDUSTRIAL AUTO-IMU

Reliable accuracy with automatic IMU initialization
The i93 GNSS receiver features CHCNAV’s state-of-theart 200 Hz Auto- IMU,eliminating manual initialization and simplifying field surveying. With IMU corrections available even when the range pole is carried on the shoulder, in the hand, or placed horizontally, the i93’s IMU-RTK automatic pole tilt compensation technology can boost surveying, engineering, and mapping efficiency  by 30%. The i93 enables measuring and stakingwith survey-grade accuracy over a pole-tilt of up to 30 degrees, ideal for engineers, site managers, and surveyors.
