Spacecraft Formation Flying in Eccentric Orbits
JOURNAL OF THE JAPAN SOCIETY FOR AERONAUTICAL AND SPACE SCIENCES, 2008 Formation flight of spacecraft in eccentric orbits is considered in this paper. Symmetry of the eccentric orbits is assumed in a relative formation orbit, and under this assumption, relations of initial conditions in formation flight are derived. Some characteristic orbits are obtained from these relations, such as an orbit where a deputy spacecraft ...
