天文测量中减弱大气折射影响的方法

Reducing Affection of Atmospheric Refraction in Astronomical Survey

大气折射是对天文测量精度影响较大的因素之一,至今无法将其完全消除,只能尽量减弱。因此,处理好大气折射改正,是提高天文测量精度的一项重要任务。文中分析了大气折射的特点,介绍了传统天文测量对大气折射的处理方法;研究并实现了新的处理大气折射的方法,给出了具体解算公式。新方法的应用,使天文测量的效率、精度都得以大大提高。

Atmospheric refraction is one of the vital factors of affecting precision in astronomical survey. We can not eliminate it,but only reduce it. It is an important task that reduce affection of atmospheric refraction in astronomical survey. In this paper, characteristic of atmospheric refraction is analyzed, methods of dealing with atmospheric refraction in traditional astronomical survey are introduced. New method of dealing with atmospheric refraction is researthed and realized, material formulas has been given. Efficiency and precision of astronomical survey have been improved greatly by using new method.
