Overview
Tethered Boats
Riverboat SP Teledyne Marine Tethered Boat
Tethered boats are autonomous surface vessels (ASVs) moored in a fixed position in order to provide a stable measurement platform. They are usually equipped with acoustic Doppler current profilers (ADCPs). These sensors measure the velocity of river currents and discharges via use of the Doppler effect, in which a measurable frequency shift of the acoustic pulse occurs due to the movement of the water.
Tethered boats can also be equipped with depth sounders, as well as a range of radio communications and GPS positioning devices.
