To provide a target tracking apparatus which estimates the position of a target highly accurately.SOLUTION: A target tracking apparatus includes a communication device and a calculation device. The communication device performs communication with a plurality of observation satellites which observe targets. The calculation device executes satellite selection means, schedule setting means and estimation means. The satellite selection means selects two or more selection satellites for observing the target from the plurality of observation satellites. The schedule setting means decides an observation schedule, along which the targets are observed by each of two or more selection satellites and transmits an observation request signal which expresses the decided observation schedule to the corresponding selection satellite. The estimation means estimates a target position based on two or more kinds of high-accurate observation information observed by each of two or more selection satellites.SELECTED DRAWING: Figure 1

    【課題】目標の位置を高精度に推定する目標追跡装置を提供する。【解決手段】目標追跡装置は、通信装置と、演算装置とを備える。通信装置は、目標を観測する複数の観測衛星と通信を行う。演算装置は、衛星選択手段と、スケジュール設定手段と、推定手段とを実行する。衛星選択手段は、複数の観測衛星から目標を観測する2以上の選択衛星を選択する。スケジュール設定手段は、2以上の選択衛星の各々が目標を観測するための観測スケジュールを決定し、決定された観測スケジュールを表す観測要求信号を対応する選択衛星に送信する。推定手段は、2以上の選択衛星の各々が観測した2以上の高精度観測情報に基づき、目標の位置を推定する。【選択図】図1
