Abstract
An information processing device includes a predicted position acquisition means, an estimated position calculation means, a reliability calculation means, and a velocity calculation means. The predicted position acquisition means acquires a predicted position of a ship. The estimated position calculation means calculates an estimated position of the ship in which the predicted position is updated, based on a matching between data based on an output of an external sensor provided on the ship and map data. The reliability calculation means calculates a reliability of the matching. The velocity calculation means calculates a velocity of the ship at a first process time based on the estimated position at the first process time, an estimated position at a second process time immediately before the first process time, and a time constant set depending on at least the reliability.
