PURPOSE:To attempt improved response in tracking a ship by setting up the content in memory of a speed registor based on the outputs of speed and course detection devices for the ship. CONSTITUTION:The memory content of counters TM and TS1-TSn of sampling timing in the stage of signal catching is changed based on the memory content of a speed registor MV. The course from a gyrocompass 12 and the speed relative to water from a log 11, are respectively inputted. From those data, on station position, an estimated speed in sampling timing are sought. With this arrangement in which the speed in sampling timing is sought from the speed of an actual ship, the response performance of tracking becomes excellent. |
