CHCNAV i76 Palm-Sized Visual GNSS RTK Receiver
The CHCNAV i76 is a palm-sized GNSS RTK receiver designed for surveyors who want a compact instrument without giving up visual positioning and tilt compensation capabilities.
Weighing only 450 g, the i76 combines GNSS, a 5th-generation IMU and dual wide-angle cameras in a small field-ready receiver. Its CAD-based AR stakeout functions provide visual guidance, while the IMU supports pole tilt compensation during point measurement.
The compact design makes the i76 particularly suitable for construction stakeout, utility mapping and field surveys where equipment portability is important.
RTKSurvey supplies the CHCNAV i76 for professional surveying, construction and mapping applications.
Key Features
Palm-Sized 450 g Receiver
The i76 is designed for easy one-handed handling and reduced operator fatigue. Its compact body is suitable for surveyors who frequently move between measurement points.
CAD AR Visual Stakeout
The i76 combines CAD data with augmented reality to provide visual guidance during stakeout and help surveyors plan and follow target locations.
5th-Generation Ultra-IMU
The built-in IMU supports automatic pole tilt compensation up to 60°. CHCNAV specifies accuracy within 3 cm across the stated tilt range without manual initialization.
Dual Wide-Angle Cameras
Two 2 MP cameras with a 95° field of view support visual positioning, stakeout and field measurement workflows.
GNSS RTK Performance
The i76 uses a 4th-generation GNSS antenna and iStar 2.0 technology for reliable satellite tracking and RTK positioning.
Base and Rover Capability
The built-in 410–470 MHz UHF radio allows the receiver to operate as either a base or rover in compatible configurations.
Rugged IP68 Housing
The i76 is IP68-rated and designed to withstand a 2 m drop, making the compact receiver suitable for demanding outdoor work.
