摘要
本文介绍了太阳位置获取的方法及将其转换至地固系和当地切平面坐标系的方法,还介绍了太阳视位置计算的原理和方法,同时考虑了遮挡物对太阳遮挡的计算,结合实例计算获得了太阳在地固系内的直角坐标以及太阳的视位置和遮挡情况,并绘制了直观的太阳与遮挡墙的视位置图,从而计算出测站处太阳光照的时间,其在研究及实际应用需要中具有一定的现实意义。
This paper introduces the methods of solar position obtaining and its transition into conventional terrestrial system and local tangent plane coordinate system. It also recommends the principle of solar apparent place while taking solar occlusion calculation into account. Then, in combination of a case calculation, a visualized figure of sun and occlusion apparent place is drawn out by results. Consequently, the sunshine time which has practical significance for study and application is calculated in a station.
