The new RIEGL VQ-840-G is a fully integrated compact airborne laser scanner for combined hydrographic and topographic surveying. The system is offered with an integrated and factory-calibrated GNSS/IMU system and can be complemented with an optional camera or IR rangefinder. The new 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 hydrographic airborne and UAV-based survey
• High accuracy ranging based on echo digitization and online waveform processing with multiple-target capability
• Concurrent comprehensive full 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
• Additional, fully integrated infrared laser rangefinder (optional)
• 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
