摘　　要：文章分析太阳同步轨道人造地球卫星在不同条件下的在轨星等变化情况。文章精确分析太阳同步轨道卫星运行中,太阳光与轨道面的夹角随日期而变化,从而得到太阳同步轨道卫星的星等的变化情况。降交点地方时作为太阳同步轨道卫星重要参数,其对观测星等的影响文章也做了相应分析。In this paper, the variations of orbiting magnitude of solar synchronous orbit artificial earth satellites under different conditions are analyzed. In this paper, the angle between the solar light and the orbit plane in the operation of the sun synchronous orbit satellite is analyzed accurately with the date, and the change of the magnitude of the sun synchronous orbit satellite is obtained. As an important parameter of the sun-synchronous orbit satellite, the influence of the local time of the nodal point on the observa- tional magnitude of the satellite is also analyzed in this paper.
