Non-contact laser scanner VQ-860-G

for aeronauticsairbornemeasurement

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. The complete system is offered with an optionally integrated and factory-calibrated IMU/GNSS system and a digital camera. The RIEGL VQ-860-G is a compact and versatile system designed for straight forward integration on crewed aircraft. 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 water proof housing enable long-term operation on airborne platforms. 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 on the seafloor and in the water column. Main Features excellent depth performance wide operational envelope: flight altitudes from 75 m to 300 m high accuracy ranging based on echo digitization and online waveform processing with multiple-target capability concurrent comprehensive full waveform storage of all measurements for subsequent full waveform analysis high spatial resolution due to measurement rates of up to 100 kHz and high scanning speed of up to 100 scans/sec
