COMPLETE SOLUTION FOR SURVEYING UNDERWATER STRUCTURES AND TOPOGRAPHY
Small and Lightweight Topo-Bathymetric Airborne LiDAR System
RIEGL’s “All-in” Package includes:
- compact, powerful LiDAR sensor providing up to 2.2 Secchi depth
- RIEGL RiLOC-F inside inertial navigation system
- an integrated RGB camera to complement the LiDAR data with imagery
- RIEGL's proprietary software licenses for generating georeferenced and refraction-corrected point clouds
The compact design and the light weight of just 5.7 kg / 12.5 lbs make the RIEGL VUX-820-G especially well-suited for use on UAVs. Extra features like a display and status LEDs enhance interactive handling and operation.
The VUX-820-G, RIEGL’s complete solution for topo-bathymetric surveys, makes the bathymetric LiDAR more accessible by enabling easy integration and operation.
Main Features
- lightweight 5.7 kg (12.5 lbs)
- Integrated RIEGL RiLOC-F inside inertial navigation system
- Integrated RGB camera
- designed for combined topographic and bathymetric UAV-based survey
- high accuracy ranging based on echo digitization and online waveform processing with multiple-target capability
- concurrent comprehensive full waveform storage for all measurements
- high spatial resolution due to measurement rate of up to 100 kHz and high scanning speed of up to 50 scans/sec
- compact, lightweight and robust housing for easy mounting on UAV or integration into payload pods when used with crewed aircraft
- status information display and system parametrization via user interface

Main Applications
- Coastline and Shallow Sater Mapping
- River and Water Reservoir Surveying
- Monitoring Tasks in Hydro Engineering and Harbor Management
- Hydro Archeology
