CHCNAV i83 Smart Versatile IMU+RTK Receiver
The i83 GNSS receiver is more than a universal 1408-channel multi-band IMU-RTK GNSS receiver, it is the perfect GNSS RTK survey tool that any surveying, construction or mapping professional has come to expect. Built-in connectivity modules such as Wi-Fi, Bluetooth, NFC, UHF and 4G modem can be used reliably, efficiently and conveniently in a variety of application scenarios to meet any job site configuration.
The i83 GNSS features CHCNAV’s third-generation GNSS antenna and the latest iStar algorithm to increase all GNSS signals tracking efficiency by 30%. It also integrates a premium calibration-free IMU sensor, which greatly improves the usability and reliability of RTK GNSS surveys. Designed for extended field use and robust performance, the i83 GNSS smart power management technology allows for up to 34 hours of continuous RTK rover operation. The i83 GNSS provides unparalleled productivity for GNSS measurements, stakeout surveys and other typical construction tasks.
