The present work aims at constructing an atlas of the balanced Earth satellite orbits with respect to the secular and long periodic effects of Earth oblateness with the harmonics of the geopotential retained up to the 4th zonal harmonic. The variations of the elements are averaged over the fast and medium angles, thus retaining only the secular and long periodic terms. The models obtained cover the values of the semi-major axis from 1.1 to 2 Earth’s radii, although this is applicable only for 1.1 to 1.3 Earth’s radii due to the radiation belts. The atlas obtained is useful for different purposes, with those having the semi-major axis in this range particularly for remote sensing and meteorology.

平衡的低地球卫星轨道

目前的工作旨在针对地球扁率的长期和周期性影响建立平衡的地球卫星轨道图集，其中地球电势的谐波保留到第四级纬向谐波。元素的变化在快角和中角上平均，因此仅保留了长期和长期周期项。所获得的模型涵盖了从1.1到2地球半径的半长轴的值，尽管由于辐射带的缘故，这仅适用于1.1到1.3地球半径。获得的地图集可用于不同目的，其中半长轴在此范围内的地图集尤其适用于遥感和气象。
