For pt.II, see ibid., no.5, p.149-55, March 1975. Navigational problems in merchant ships are discussed with particular attention to steering, and the maintenance of a course, relative to a compass course, under the influence of currents, surface waves and hydraulic damping factors. Algebraic and differential equations are given, with rate-of-turn defined as the first derivative of the compass course with respect to time. A block diagram shows the principle of the PID analogue-computer control of steering. On-line navigation systems are noted in the context of radio senders and receivers, typically in the 10 to 14 kHz range, using several sending stations and a lane identification technique.
