65cm水平式望远镜静态指向模型

Static Pointing Model of 65 cm Level Mounting Telescope

由于传统的静态指向模型对于水平式装置存在法方程条件差的困难,针对紫金山天文台盱眙站65 cm水平式空间碎片望远镜,基于真实的可能产生误差的来源建立了独特的静态指向模型,使模型参数具有明确的物理意义,从而基本剔除了望远镜的系统误差,大大提高了该望远镜的指向精度,达到了4”．

Because of the difficulty of traditional static pointing model for level mounting telescope, a new static pointing model was built for 65 cm level mounting space debris telescope in Purple Mountain Observatory. This model is based on actual sources of error, so the model coefficients have clear physical meaning and most of the system errors were rejected. The pointing accuracy is greatly improved to 4＂.
