SpletA multibeam sonar is a device capable of mapping a broad swath of sea bottom. It generally creates a three-dimensional model of the seabed. Applications This equipment is generally used for seabed mapping, oceanographic applications, bathymetric studies and underwater excavations. Technologies SpletThe sonar itself contains a three axis magnetometer and a three axis accelerometer which combine to stabilise the motion of the platform and provide heading information. An …
SpletSolstice, developed by our sister company Wavefront Systems and manufactured and commericalised by Sonardyne, is the number one side scan sonar in the world for AUVs and towed bodies. The imagery produced is recognised to be of the highest quality possible from side-scan sonar enabling detection and classification of seafloor objects across the … SpletThe beams are equally distributed across the swath. The sonar takes the nadir range and then computes the necessary beam angle to distribute the beams equally spaced across the swath. Equidistant mode assumes a more or less flat bottom and a swath angle of no more than 130°. Equidistant mode cannot be used when mapping vertical features.

With its high ping rate and wide maximum swath coverage of 180 degrees, Atec 400 is especially effective in shallow water survey. At greater depths, one can reduce the swath range in order to increase the ping rate.
