Possible changes of the AES orbit caused by a passage through the Moon's shadow

Abstract

The change in the eccentricity of the AES orbit of the type 1963-30D as a result of one passage through the Moon's shadow is estimated, and it has been shown that the effect is not negligible.

The effects of the Moon's shadow and pre-shadow on the artificial satellites motion

“…The artificial satellites, in their motion around the Earth, can sometimes enter the Moon's shadow. 1,2 The probability of the satellite's entry the Moon's shadow can not be considered small, 3,4 as it is equal to 5% for the near-equatorial orbits with semi-major axes of 10-15 radii of the Earth. The problem of precomputing the Luni-Solar eclipses for the geostationary satellites was considered by several authors.…”
