摘要: 采用轨道叠加的方法,对将单天解轨道合成为多天解轨道算法过程进行了详细推导,并通过算例证明了轨道合成对提高轨道产品精度(特别是在局域定轨中)的有效性。同时对利用动力平滑的方法实现简化的轨道合成进行了原理分析,并对基于法方程叠加的轨道合成与利用动力平滑的方法进行简化的轨道合成方法进行了比较。Abstract: The algorithm of using one-day-arcs to integrate n-days-arc by the way of orbit overlaying is discussed in detail.An example is given,which proves that the orbit integration method can improve the accuracy of orbit efficiently,especially in local area orbit determination.Meanwhile using the power smooth method to carry on the simplification orbit integration is analyzed.
