提出了一种用于探测器借力飞行段的自主光学导航方案。该方案利用星敏感器以及光学导航相机,通过测量恒星平行光方向及对行星张角,利用几何关系计算出探测器的相对位置,并利用扩展卡尔曼滤波算法进行修正,最后通过仿真验证了这种自主光学导航方案的可行性。
An autonomous optical navigation scheme for the leap flight of the detector is proposed. The scheme uses the star sensor and the optical navigation camera to calculate the relative position of the detector by measuring the parallel light direction of the star and the angle of the planet. The scheme is corrected by the extended Kalman filter algorithm. Finally, the simulation results verify this Feasibility of autonomous optical navigation scheme.
