ROTAN

History

One of the people who developed ROTAN was Walt Phelps, in 1957 or 1958. Development took place either in Building 86 or in Building 81, most likely Building 86.

The November 26, 1959 issue of TekTalk states that:

[ George Edens ] is largely responsible for developing the Rotan transducer system for velocity and acceleration systems.
