摘要
中国实验光干涉仪恒星跟踪器的硬件部分——光机电结构已经确定下来了。但是,它的软件部分——跟踪模式还没有确定下来。为了达到0″.2的星光方向跟踪精度。本文设计了一种新的跟踪模式:用步进方式实现捕获;用统计滤波方式实现跟踪;对各类失锁情况具有自动修复功能。计算机模拟的结果表明,这种跟踪模式是可行的,在一般情况下能够达到要求的精度。
The hardware structure of star tracker in Chinese Interferometer has been determined. But its software struture, tracking mode, has not been determined. In this paper, a new tracking mode was given in order to meet the need in precision(0″.2). The new tracking mode includes two main processes, the seeking process and the tracking process. If controllor does not find or losts target, the star tracker will be working in seeking process. Seeking means pacing with changeable pace. If eontrollor has found target, star tracker will be working in tracking process. We realise tracking with statistic filtering method. The simulation results shows that we can meet the need in precision under normal condition.
