CHCNAV i93 IMU-RTK GNSS Receiver
The CHCNAV i93 is a professional IMU-RTK GNSS receiver designed for surveying teams that need more than conventional point measurement. It combines high-performance GNSS positioning, automatic IMU compensation and dual-camera visual surveying in one field receiver.
The i93 can work as either an RTK rover or GNSS base station. Its visual surveying functions are useful when direct access to a point is difficult, while AR visual stakeout helps surveyors work with real-time visual guidance.
The receiver also supports PointSky satellite corrections for areas where cellular coverage is limited or setting up a local base station is inconvenient. With 1,892 GNSS channels and a 200 Hz IMU, the i93 is designed for demanding surveying and construction workflows.
RTKSurvey.com supplies the CHCNAV i93 for professional land surveying, mapping and engineering applications.
Key Features
Dual-Camera Visual Surveying
The i93 uses dual cameras to capture visual information and obtain survey-grade 3D coordinates. This allows surveyors to work with points that may be difficult, unsafe or inconvenient to reach directly.
AR Visual Stakeout
Visual guidance can assist with construction and surveying stakeout by showing the direction and distance to target points directly in the field.
1,892-Channel GNSS
The i93 uses a 1,892-channel GNSS configuration for multi-constellation and multi-frequency satellite tracking.
200 Hz Auto-IMU
The built-in 200 Hz IMU provides automatic pole tilt compensation, reducing the need to keep the survey pole perfectly vertical during field measurement.
PointSky Satellite Corrections
PointSky provides satellite-delivered positioning corrections for areas where a local base station or reliable cellular network is difficult to use. The official product information specifies 3 cm positioning accuracy within 3–10 minutes under the stated conditions.
Rover and Base Station Operation
The i93 can be configured as either an RTK rover or GNSS base station, with integrated 4G and UHF communication for different correction workflows.
