Single Beam Echo Sounder

SBES are typically carried out to determine the river/sea bed levels accurately in 2D and 3D. The data is typically used by engineers, architects, port authorities, civil contractors and modellers to facilitate developments, planning and monitoring.

HHS has invested heavily in the latest survey equipment and processing software in order to achieve the most accurate data possible and to pass on savings to the client as the whole data capture and processing routine workflow is streamlined. HHS primarily use Trimble R8 GPS and S5 total station which operate as one integrated survey unit, in addition they are easily interfaced to third party devices which maintains the integrity of the data and enables HHS to deliver the highest quality data possible in either digital of hard copy format. The equipment can be quickly setup and calibrated on vessels of opportunity and can be easily allow either GPS or total station to out positional information to be logged.


SBES data sets have a wide range of end users, a typical end use would include
