GPS Instrument Company

The high-speed iterative analog computer from GPS Instrument Company. The microsecond electronic integrator switching controls enabled the user to solve boundary value problems, employ multiple time scales (two or more time dimensions) in solving certain partial differential equations, and in general, through repetitive simulation techniques find embedded optimum solutions. The iterative group was first demonstrated at the Fall Joint Computer Conference in 1961.


Repetitive Operation Analog Computer

Mike Hmelovsky donated this Analog Computer on 13-June-2021. It was originally used at the University of Hartford in the 60s.

An early pioneer in individual analog computing units and high-speed integrators for repetitive operations was the Boston firm Geo. A. Philbrick Researches, Inc., later Teledyne Philbrick Inc. Its founder, George A. Philbrick, promoted the use of analog computing using his “black boxes” as flexible and effective engineering analysis tools. In the years from 1946 to 1966, his firm was in the forefront of both high-speed and real-time electronic analog computing.
