空间目标的圆轨道跟踪法

Circle-orbit Tracking Method of Space Object

给出一种空间目标自动跟踪方法:圆轨道跟踪法.该方法在假设目标轨道为圆轨道的前提下计算目标轨道,而后在轨道平面中外推.和位置跟踪法比较表明:该方法不受空间目标视运动不均匀性的影响,有非常高的跟踪精度.即使采用低帧频CCD(1—2 HZ),使用本方法,也能实现对空间目标的高精度跟踪;并能给出目标的多点CCD坐标,实现对空间目标的多点分区采样,提高空间目标的定位精度.

Circular orbit tracking method is proposed in this paper. This method determinates the orbit of space object firstly on the assumption that the orbit of space object is circular orbit, and extrapolates the next position in orbital plane. Compared with position tracking method, circular orbit tracking method is not influenced by the unevenness of apparent motion and has highly tracking precision. By using the methods, even if the telescope is installed low frame-frequency CCD (1-2HZ), it also realizes to track space object with high precision, and gives the many CCD coordinate points to sample object in many different regions, and improves the measured precision of space object position.
