CHCNAV i93+(X16) IMU Ibase RTK GPS Gnssgps RTK High Precision Survey Equipment Gnss

The i93 is a cutting-edge surveying tool that combines GNSS, IMU, and two premium global shutter cameras with video photogrammetry technology. It delivers survey-grade 3D coordinates from real-world video capture in seconds, making it easy to survey previously hard-to-reach, signal-obstructed, and hazardous points in the field, such as under overpasses, under eaves, and near power poles. With its dynamic panoramic video capture and automatic image matching, the i93 improves productivity by up to 60%. Automatic high-speed continuous shooting and adjacent image generation with up to 85% overlap ensure high processing success. Surveyors looking for ease, speed, and accuracy will find the i93 an ideal tool. 

The i93 GNSS features CHCNAV's state-of-the-art 200Hz Auto-IMU, which eliminates the need for manual initialization and simplifies surveying operations in the field. With IMU corrections available even when the range pole is carried on the shoulder, in hand, or placed horizontally, the i93's IMU-RTK automatic pole tilt compensation technology can boost surveying, engineering, and mapping speed and efficiency by up to 30%. Measuring and staking out with survey-grade accuracy over a pole tilt of up to 60 degrees is fast, easy, and highly productive, making the i93 the perfect solution for engineers, site managers, and surveyors. 

The i93 has all the connectivity features a surveyor needs to complete any GNSS survey project scenario. Built-in Wi-Fi, Bluetooth, and NFC technologies allow 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.
