Digiplot is a marine radar aid for automatic anti-collision navigation which processes signals from conventional radar and presents computed information on a separate screen to give at-a-glance situation appreciation. The company's origin is touched on and conception and design are described as they evolved to meet operational requirements.

The majority of sophisticated radar equipments and devices available today have evolved from successive shipborne radar developments over a considerable period of years. With Digiplot it is otherwise. The Iotron Corporation was established in 1969 by a few men whose background had been information technology in the realms of fire control and navigational systems for submarines, aircraft, missiles and spacecraft, and reconnaissance systems using electronic and optical techniques; in all these systems digital electronics played a key role. The choice of the navigational functions of marine radar as the most appropriate subject for attention by the group was made after a general study of the commercial field, because of the revolution apparent in ships, their equipment and their operations.
