Smart IMU-RTK.Robustly connected.
The CHCNAV i83 pairs 1408-channel GNSS with a calibration-free 200 Hz IMU — RTK in under 10 seconds, tilt up to 60°, and Wi-Fi, Bluetooth, UHF and 4G built in so every correction source stays connected.
Surveying, minus the tripod time
One receiver that stays connected and never needs levelling — survey, stakeout and site control in a single device.
1408-channel GNSS
CHCNAV's iStar2.0 engine tracks GPS, GLONASS, Galileo, BeiDou, QZSS, NavIC and SBAS — reliable fixes measured in millimetres, even in tough environments.
Connected everywhere
Wi-Fi, Bluetooth, NFC, UHF and a 4G modem built in — every controller and correction source stays connected, no dongles.
Calibration-free tilt
The 200 Hz AUTO-IMU measures at up to 60° of pole tilt with E-Bubble levelling — up to 30% faster surveys, no calibration routine, immune to magnetic interference.
Status at a glance
A 1.1" colour OLED plus LEDs and two buttons — satellite count, RTK state and battery without opening a menu.
34-hour battery
9,900 mAh built in — up to 34 h as an RTK rover or 16 h as a base. Survives a 2 m pole drop.
Built for the site
IP67-sealed magnesium alloy body, MIL-STD-810H rated for shock and vibration — dust, rain and the ute tray.
