摘要: Apparatus for indicating the distance travelled by a vessel comprising a counter that operates cyclically and for periods of time during each cycle which is a linear function of the velocity of the vessel. The counter is operated with a control circuit which is energized in response to an electrical output signal that is substantially proportional and linear to the velocity of a vessel and a second electrical signal that varies linearly with time between two set values.
