Abstract

A statistical analysis of selected parameters of solar activity and orbital motion of artificial Earth satellites (AES’s) during solar cycle 24 is carried out. Inactive satellites, launch vehicle (LV) stages, and their debris moving mainly in low orbits are studied. Different analysis algorithms are applied to the time series of the solar radio flux F_10.7 and the calculated deceleration rate dP/dt of the investigated space objects (SOs): their annual statistical indices are estimated, these parameters are studied for periodicity (wavelet analysis), and a test additive decomposition into trend and seasonal components is performed. It is found that the satellite deceleration rate in the vicinity of the solar maximum (2012–2014) increases by a factor of ten. For the solar radio flux F_10.7 and the kinematic parameter dP/dt of SOs 06073 and 31117, seasonal changes, cyclicity with a period of 27 days, etc. are confirmed. A clear anticorrelation between the trends of the corresponding parameters within –0.73…‒0.95 for SO 31117 during 2011–2018 and –0.82…–0.95 for SO 37794 during 2012–2018 is observed.

第24太阳活动周期选定人造地球卫星轨道运动的统计分析

对第24太阳活动周太阳活动和人造地球卫星轨道运动的选定参数进行了统计分析。研究了非活动卫星、运载火箭(LV)级及其主要在低轨道上运动的碎片。采用不同的分析算法对被调查空间物体的太阳射电通量F10.7和计算的减速率dP/dt的时间序列进行了分析，估计了它们的年统计指标，研究了这些参数的周期性(小波分析)，并进行了趋势分量和季节分量的试验加性分解。研究发现，在太阳活动极大期(2012-2014)附近，卫星减速率增加了10倍。对sos06073和sos31117的太阳射电通量F10.7和运动参数dP/dt进行了季节变化、周期为27 d等确认。so31117在2011-2018年和so37794在2012-2018年期间对应参数的变化趋势在-0.73…-0.95之间呈明显的反相关关系。
