摘要 研究导航卫星自主定轨中地球定向参数误差的修正方法,建立了由于地球定向参数误差所引起的卫星坐标误差的改正公式,提出了两种地球定向参数误差的地面修正方法。试算结果表明:该方法具有很好的精度,足以满足广播星历的要求。 This paper researches the correction method for the error of earth orientation parameters in AOD (Autonomous Orbit Determination) of navigation satellites. A correction formula of error of satellites' coordinates which is resulted from error of earth orientation parameters is constructed, and two kinds of ground correction methods is put forward. The result of calculation indicates that the accuracy of correction method is high enough for meeting the requirement of broadcasting ephemeris.
