To provide a technique for achieving flexible communication by setting communication opportunities on demand that are not in a predetermined communication schedule in inter-satellite optical communication.SOLUTION: One aspect of the present disclosure includes: an orbit prediction unit that predicts the orbit of a relay satellite that relays communication between a satellite having an optical communication unit and an earth station; a communication planning unit that creates a communication plan between the satellite and the relay satellite; a setting unit that sets an unplanned communication period during which there is a possibility of unplanned communication between the satellite and the relay satellite; and a creation unit that creates control information for controlling the optical communication unit so that the optical communication unit points to and tracks the relay satellite over the unplanned communication period based on the predicted orbit.SELECTED DRAWING: Figure 10
【課題】衛星間光通信において予め決定された通信スケジュールにない通信機会をオンデマンドで設定することにより、フレキシブルな通信を実現するための技術を提供することである。【解決手段】本開示の一態様は、光通信部を有する衛星と地球局との間の通信を中継する中継衛星の軌道を予測する軌道予測部と、前記衛星と前記中継衛星の通信計画を作成する通信計画部と、前記衛星と前記中継衛星との間で非計画通信の可能性がある非計画通信期間を設定する設定部と、予測した前記軌道に基づいて、前記非計画通信期間に亘って前記光通信部が前記中継衛星を指向追尾するように前記光通信部を制御する制御情報を作成する作成部と、を備える。【選択図】図１０
