摘　　要：推导出射向标定测量中天文归心计算公式,通过实测数据,对其适用范围进行了分析。结果表明,在中纬度平坦地区,偏心距小于1 000 m时,天文成果归心计算的精度在纬度0.2"、经度0.01 s、方位角1"以内。The astronomic eccentric reduction formulas in the orientating launch survey are proposed,whose applicability is analyzed by some experimental data.The precisions of astro nomic eccentric reduction are not larger than 0.2＂of latitude,0.01 s of longitude,1＂of azimuth only if the eccentricity is less than 1000m in the flat zones of middle latitude.
