<p>A turn masking assessment process unit (5) is provided that assesses whether or not signal masking accompanying turning of an airliner has occurred between the airliner, which is the target of said assessment, and multiple receiving stations. If the turn masking assessment process unit (5) has assessed that the signal masking accompanying the turning of the airliner has occurred, a filter reset process unit (6) outputs to a positioning position tracking process unit (3) a filter control signal that directs a reset of a track given by a linear Kalman filter.</p> |
