NRL in the past 2 years has developed three oceanographic computers ssystems. The computer systems are based around Hewlett-Packard 2100 Series computers. The software used in a Real-Time Executive with multiprogramming and multiuser capabilities. NRLs philosophy has been to acquire and process the data in the field automatically, in real time, using the oceanographic computer systems. To accomplish this goal, much attention has been placed upon the interfacing of special-purpose as well as general-purpose devices to the computer system. Many special-purpose devices have already been interfaced to the computer system, such as navigation equipment, ship sensors, aircraft sensors, atmospheric sensors, and magnetometers. General-purpose devices such as random access disks and digital magnetic tapes have been provided in order to access and save the data. Also, several graphical plotting devices are available, including a large flatbed plotter along with displays and line printers to obtain and view the results. A special Fourier analyzer that works in conjunction with a dedicated HP2100 computer is used when real-time and off-line spectrum analysis is required. The oceanographic computer systems have been operated aboard ship and in aircraft alike.
