  1. The orientation information of the sun, the moon and the earth, together with ephemeris are utilized to develop autonomous navigation algorithm, as well as its realization by dsp hardware

    在小樣本觀測數據情況下,研究利用日地月方位信息和日月星歷表進行航天器自主導航以及利用dsp實現航天器自主導航器的技術。
  2. In the stage of the sun and the moon in sight, azimuth of the sun, the earth and the moon in the spacecraft body coordinate system is simulated. combining the simulated azimuth with the ephemeris of the sun and the moon, the state equation and observation equation are modeled. the initial orbital parameters calculated by least square method are used in orbit state equation to predict spacecraft state and to realize autonomous navigation

    在日月可見階段,模擬日、地、月敏感器測量信息,即日、地、月在航天器本體坐標系下的方位信息,結合日月星歷,建立狀態方程及觀測方程,通過最小二乘法得到歷元時刻的軌道狀態初始值,將其代入軌道狀態方程進行自主導航。
