Abstract

In a locator, a data synchronization unit calculates an interpolated value for autonomous sensor data which corresponds to a time of latest GNSS data. A complex positioning unit performs complex positioning using the latest GNSS data and the interpolated value for the autonomous sensor data. An autonomous navigation positioning unit performs first autonomous navigation positioning using the interpolated value for the autonomous sensor data, and performs second autonomous navigation positioning using latest autonomous sensor data. A modified amount calculator calculates a modified amount of autonomous navigation positioning, based on a difference between a result of the complex positioning and a result of the first autonomous navigation positioning. An autonomous navigation positioning fix modification unit modifies a result of the second autonomous navigation positioning using the modified amount to calculate a current position.
