摘　　要：星图模拟的研究大多集中在基于星敏感器的天文定姿领域,应用基于地面的天文大地测量的星图模拟几乎为空白。本文针对天文大地测量计算模拟需求,研究了一种基于地面可模拟多种视场的星图模拟方法,并对模拟方法的总体构想、恒星位置计算和模拟显示做了说明和推导,编制了星图模拟软件。测试表明,软件可较好地模拟不同视场不同亮度的恒星分布,并对恒星矢量图进行输出。Star map simulation is researched mostly in astronomical attitude determination based on star tracker,which is rarely used in astronomical geodetic observations.The paper aimed at requirement of astronomical geodetic calculation,introduced a star map simulation method that could simulate various fields of view on ground,proposed simulation construction,introduced calculation of star location and simulation show,finally,software of star map simulation was edited.Test showed the software could simulate different brightness stars with various fields of view,and the star vectors was exported.
