针对现有数据微分处理方法的缺陷,采用容错思想改进了传统的数据处理算法,提出容错拟合微分技术。新算法有效地消除了各类孤立型野值和斑点型野值的不利影响,降低了算法对随机误差的敏感性,提高计算弹道的可靠性和精度。通过仿真和工程实践计算,验证了该算法的有效性和适用性。
Differential technique has an important place in the field of spaceflight.This paper advances fault-tolerant algorithm of numeric differential method to improve old LS algorithm.New method can eliminates availably the influence resulting from the AO & IO outliers,and reduces the sensitivity to stochastic error.Through resembling using the data from project practice,new idea is valid and applicable.
