Description
Stationkeeping of quasiperiodic orbits near a periodic halo orbit of the
Earth+Moon-Sun system is analyzed. The full solar system is considered
as a perturbation of the restricted three body problem. In the full
solar system the periodic orbits are lost but the system still has quasi
periodic solutions relatively close to the previous halo orbits. They
are approximately obtained analytically and refined numerically. These
orbits can be taken as nominal orbits for halo missions. They inherit
the unstable character of the halo orbits. Although they are no longer
periodic their invariant manifolds, which are approximated by analytical
and numerical solutions of the variational equations, can be introduced.
Simple geometrical considerations help to develop a very cheap
stationkeeping algorithm.
