The CHCNAV i76 is a palm-sized GNSS RTK receiver combining satellite positioning, IMU technology and dual cameras for construction stakeout and utility mapping.
CAD AR visual stakeout integrates digital base maps with real-time augmented reality guidance, helping users locate design points and plan efficient routes.
Dual 2 MP cameras with a 95° field of view provide clear visual guidance, supporting precise foundation layout and construction site stakeout.
The fifth-generation Ultra-IMU supports tilt compensation up to 60° with a 200 Hz update rate, allowing measurements without keeping the pole vertical.
Weighing just 450 g, the i76 delivers up to 17 hours of RTK rover operation. Built-in UHF, Bluetooth, Wi-Fi and NFC support flexible connectivity.
IP68 protection, resistance to a 2-metre drop and operating temperatures from −40°C to +65°C provide durability for demanding field conditions.
