LIDAR Scanning
VQ-840/860 Series
The VQ-840/860 Series are fully integrated compact airborne laser scanners 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. These scanners are compact and lightweight LiDAR systems 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 Applications
Coastline and Shallow Water Mapping
Surveying for Hydraulic Engineering

VQ-840-GL
The proven form factor and the use of very lightweight material enable a reduced weight of less than 10 kg (22 lbs), making the VQ-840-GL suitable for integration into crewed aircraft and UAVs.
The distance measurement is based on the time-of-flight measurement with very short laser pulses and subsequent echo digitization and online waveform processing. To handle target situations with most complex multiple echo signals, beside the online waveform processing the digitized echo waveforms can be stored on the removable data storage card for subsequent off-line full waveform analysis.
The laser beam is deflected in an elliptic scan pattern and hits the water surface at an incidence angle with low variation.
The VQ-840-GL can be complemented with an inertial navigation sensor for subsequent estimation of the instrument’s location and orientation. As a further option a high-resolution digital camera can be integrated.
The rugged internal mechanical structure together with the dust- and splash waterproof housing enables long-term operation on airborne platforms.

VQ-860-G
The RIEGL® VQ-860-G airborne laser scanner with increased performance enhances depth penetration in surveying inland waters and near shore waters for even more efficiency in bathymetric applications.
Weighing only 15 kg (33 lbs), integration into drones is also possible. Parametrization of the instrument allows high operational flexibility in order to adapt performance ideally to the survey project, with regards to the carrier aircraft‘s altitude and speed as well as the mission objective. The rugged internal mechanical structure together with the dust- and splash waterproof housing enable long-term operation on airborne platforms.
VQ-860-G Main Features
