摘要
分别利用紫外三轴姿态敏感器测出的月心方向和测距仪测出的月心距作为观测量 ,采用推广卡尔曼滤波方法实时确定出月球卫星环月期间的轨道 ,考虑到月球卫星在环月期间太阳对月球光照条件的限制 ,提出分段滤波策略 。
An autonomous real time orbit determination for lunar satellites by the extended Kalman fitering is studied in the paper. The selenocentric direction is observed by an ultraviolet three axis attitude sensor and the selenocentric distance measured by a radar altimeter. Considering the illnmination condition of the moon, a strategy of piecewise filtering which alternatively uses one of the above measurements is presented and analyzed by digital simulation.
