CHCNAV ViLi i100 Visual-LiDAR GNSS RTK Receiver with Consistent Accuracy in Obstruction

Flagship device that integrates GNSS RTK, LiDAR scanning and visual cameras in one compact receiver.
Designed to deliver centimetre-level accuracy (~5 cm) even in obstructed or GNSS-denied environments (e.g., under viaducts, near tall buildings, in forests).
Uses multi-sensor fusion: GNSS + IMU + visual cameras + LiDAR to filter multipath and reflection errors automatically.
Enables contactless surveying and real-time 3D point-cloud earthwork volume calculations on-site.
Supports standard RTK modes (CORS, UHF base-rover, PPP) and provides visual/AR stake-out capabilities for efficient surveying workflows.
