摘要:

针对空间碎片环境长期演化计算中速度和精度难以兼容的问题,提出使用一种半分析方法进行长期轨道预报。对半分析法预报精度和速度进行测试,与数值法相比,10年内低轨半长轴偏差小于7 km,预报耗时小于0.11%。为评估半分析法轨道预报的适用性,对有45年轨道数据的千余碎片进行预报,分析在轨碎片数量演化趋势。结果表明,截至2024年7月的碎片数量误差为2.4%。基于半分析法轨道预报,对空间物件长期演化模型(space object long-term evolution model, SOLEM)进行改进,并与国际典型模型进行对比,验证了改进模型的可信度较高。

Abstract:

In order to solve the problem of compatibility between calculation speed and accuracy of space debris environmental long-term evolution, a semi-analytical method is proposed for long-term orbital prediction. The prediction accuracy and speed of the semi-analytical method are tested. Compared with the numerical method, the semi-major axis deviation of the low Earth orbit in 10 years is less than 7 km, and the consumed time of prediction is less than 0.11%. To evaluate the applicability of the semi-analytical method, orbital prediction is carried out for more than 1000 space debris with 45 years of orbital data, and the evolutionary trend of the number of debris in orbit is analyzed. The result indicates that the error of the debris number as of July 2024 is 2.4%. Based on the semi-analytical orbital prediction, the space object long-term evolution model (SOLEM) is improved, and comparison with representative international models verifies the higher reliability of the improved model.

Key words: semi-analytical orbital prediction, space debris, long-term evolution, space object long-term evolution model (SOLEM)
