摘要

PROBLEM TO BE SOLVED: To provide a bow azimuth correction device to correct the output azimuth of a bow azimuth sensor automatically and accurately.;SOLUTION: A bow azimuth correction device includes an output azimuth acquisition unit, a ground course acquisition unit, and a correction unit. The output azimuth acquisition unit acquires an output azimuth that is an azimuth output by a bow azimuth sensor. The ground course acquisition unit acquires a ground course obtained on the basis of detection results of a GNSS sensor. The correction unit corrects the output azimuth, on the basis of a difference between the output azimuth and the ground course, so as to reduce the difference.;COPYRIGHT: (C)2013,JPO&INPIT
