Remote sphere-positioning system for calibration of hull-mounted echo-sounder transducers
This system provides rapid and fine remote adjustment of line
lengths when calibrating hull-mounted echo-sounder transducers by the standard
sphere method. It consists of three motor-driven reels a control panel connected
to the reels by 50m of cable, and three attachable outriggers which can be adjusted
to the vessel’s dimensions and the position of any hull-mounted transducer
needing calibration. The outriggers can also be easily adapted for the calibration
of suspended or towbody-mounted transducers. The system greatly simplifies and
accelerates sphere calibration, leading to more frequent, thorough and accurate
calibration. Two-dimensional beam-plotting in particular, is greatly facilitated.
