Attitude detection device

Abstract

An attitude detection device includes a rudder angle sensor, a speed sensor, an inertia sensor, and a control device. The rudder angle sensor detects a rudder angle of a ship. The speed sensor detects a speed of the ship. The inertia sensor detects information related to an inertial force applied to the ship. The control device finds a centrifugal force applied to the ship on the basis of a signal output from each of the rudder angle sensor and the speed sensor. The control device acquires an inclination of the ship on the basis of the signal output from the inertia sensor. The control device corrects the inclination of the ship on the basis of the output of the inertia sensor according to the centrifugal force applied to the ship.
