To achieve simplification, downsizing and power saving of devices constituting a navigation system used for approaching and docking of an artificial satellite in an aero-space.SOLUTION: A navigation system 1 for estimating a posture of an object T in an aero-space includes: an optical marker 10 attached to the object T so as to reflect light; a light irradiation part 20 to irradiate the object T with light of a predetermined wavelength range; an image acquisition part 30 to acquire an image of the optical marker 10 that reflects the light of the predetermined wavelength range; and an image processing part 40 to estimate a posture of the object T by processing the image acquired by the image acquisition part 30. The light irradiation part 20 and the image acquisition part 30 are mounted on a space flight body 2.SELECTED DRAWING: Figure 1

    【課題】宇宙空間における人工衛星の接近・ドッキングに使用される航法システムにおいて、システムを構成する装置の簡素化、小型化及び省電力化を実現させる。【解決手段】宇宙空間における対象物Tの姿勢を推定する航法システム1であって、対象物Tに取り付けられ光を反射する光学マーカ10と、対象物Tに所定波長域の光を照射する光照射部20と、所定波長域の光を反射した光学マーカ10の画像を取得する画像取得部30と、画像取得部30で取得した画像を処理することにより対象物Tの姿勢を推定する画像処理部40と、を備える。光照射部20及び画像取得部30を、宇宙航行体2に搭載する。【選択図】図1
