20. ABSTRACT (Conllnua on ravaraa alda II nacaaaary and Idanllly by block numbar) 



An electronic system has been 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.
