The invention provides a method for realizing a pointing attitude of a quantum satellite to a ground optical station. A scientific application system formulates a scientific experiment plan, includingground optical station configuration, ground optical station geographic coordinates and other parameters participating in the scientific experiment as well as exit-entry moment forecast data of the ground optical station involved in the quantum satellite transit scientific experiment plan. The quantum satellite comprises a satellite platform, and the satellite platform bears optical loads such asa secret key communication machine, an entanglement source and an entanglement transmitter. The satellite-to-ground optical station pointing top pouring attitude guidance law comprises a first attitude guidance law and a second attitude guidance law, and the satellite-to-ground optical station pointing top pouring attitude guidance law is formed after the second attitude guidance law is seamlessly combined and then the first attitude guidance law is seamlessly combined. Through the strategy of satellite platform in-orbit yawing attitude maneuver, a problem that a quantum satellite optical device keeps a polarization state with a specific requirement in a quantum satellite scientific experiment can be solved.

    本发明提供了一种量子卫星对地面光学站指向姿态实现方法,科学应用系统制订科学实验计划,包括参与该科学实验的地面光学站配置,地面光学站地理坐标等参数,以及量子卫星过境科学实验计划中涉及的地面光学站的出入境时刻预报数据;量子卫星包括卫星平台,卫星平台承载密钥通信机、纠缠源、纠缠发射机等光学载荷;本发明的涉及的卫星对地面光学站指向得上注姿态导引律包括两部分:第一姿态导引律及第二姿态导引律,以第二姿态导引律在前,第一姿态导引律在后的次序无缝组合后形成卫星对地面光学站指向的上注姿态导引律。通过卫星平台在轨偏航姿态机动的策略,可以解决量子卫星科学实验中遇到的量子卫星光学器件保持特定需求的偏振态问题。
