Welcome to RTKSurvey.com
The CHCNAV i83 is a professional IMU-RTK GNSS receiver designed for survey teams that need dependable positioning, flexible communication and long operating time.
Its 1408-channel GNSS engine tracks major satellite constellations, while the built-in 200 Hz IMU supports pole tilt compensation. The receiver also integrates Wi-Fi, Bluetooth, NFC, 4G and UHF communication, allowing it to work with different field controllers and RTK correction methods.
One of the i83's practical advantages is its extended battery endurance. With a 9600 mAh battery, the receiver can operate as an RTK rover for up to 34 hours, making it suitable for long field projects with fewer battery changes.
