Fully integrated compact airborne laser

The VQ-840-G is a fully integrated compact airborne laser scanner for combined bathymetric and topographic surveying. 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.

VQ-840-G 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

VQ-840-G Main Applications

  • mapping of coastal lines

  • coastline and shallow water mapping

  • surveying for hydraulic engineering

  • hydro-archaeological-surveying
