RIEGL VQ-840-G
The RIEGL VQ-840-G is a fully integrated compact airborne laser scanner for combined bathymetric and topographic surveying. The system is offered with an optionally integrated and factory-calibrated IMU/GNSS system and can be complemented with an optional camera or IR rangefinder. The VQ-840-G is a compact and lightweight LiDAR system to be installed on various platforms including UAVs.
The scanner carries out laser range measurements for high resolution surveying of underwater topography with a narrow, visible green laser beam, emitted from a pulsed laser source. Subject to clarity, at this particular wavelength the laser beam penetrates water enabling measurement of submerged targets.
Main Features
- designed for combined topographic and bathymetric airborne and 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 for subsequent full waveform analysis
- high spatial resolution due to measurement rate of up to 200 kHz and high scanning speed of up to 100 scans/sec
- integrated inertial navigation system (optional)
- additional, fully integrated infrared laser rangefinder or integrated digital camera (optional)
- compact, lightweight and robust housing compliant with typical hatches in aircrafts and with stabilized platforms
Main Applications
- Mapping of Coastal Lines
- Coastline and Shallow Water Mapping
- Surveying for Hydraulic Engineering
- Hydro-Archaeological-Surveying
- River Surveying
- Repeated Survey of Water Reservoirs
