Abstract : An electronic system was developed to measure and record certain hydrodynamic characteristics of a towed buoy to be the antenna platform for a submarine communications system designated BIAS (Buoy Integrated Antenna Submarine). The system is for use during submarine development-assist tow trials. The quantities measured are buoy pitch, horizontal stabilizer angle, depth (shallow and deep), cable tension at the submarine, cable scope (fine and coarse), submarine depth, and speed. An automatic depth-keeping servo system also developed for the buoy in conjunction with the above measurement system to determine the feasibility of this type of device in a varying seaway. A second electronic measurement system was developed to measure and indicate the required hydrodynamic characteristics of the buoy necessary for operation of the system during submarine patrols. The quantities measured are displayed as meter readouts and include buoy depth (shallow and deep), cable tension at the submarine, and cable scope (fine and coarse).
