| Abstract: | 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. |
