摘要: 卫星利用紫外敏感器和星敏感器进行自主导航的方法中地心矢量的测量精度是影响导航精度的重要因素之一,而地心矢量的测量又受到地球扁率的影响。在考虑地球扁率的前提下,研究了地球扁率对地心矢量测量的影响,给出了基于卫星姿态的地心矢量的补偿方法。仿真结果表明该补偿方法具有较高的补偿精度,并且能有效地提高卫星自主导航精度。

Abstract: An autonomous orbit determination method based on ultraviolet sensors and star sensors is presentedThe accuracy of the measurements of the geocentric vector plays a key role in satellite navigationbut it is affected by the earth oblatenessWith the earth oblateness taken into accountsimulations are used todetermine the effect of the earth oblateness on the geocentric vectorand a compensation process based on satellite attitudes is proposedThe results show that the compensation process has high accuracy and can improve navigation accuracy effectively
