The orbit reference of choice for the leader is a Halo orbit and the\nfollowers are assumed to follow nearby and be constrained either geometrically or in\nsize. This type of formation could be useful in the future for constructing space ports,\nspace telescopes, astronomical spacecraft requiring sun shields and, with greater num-\nbers, spacecraft swarm missions. The formation design method is constructed by firstly\nseeking the local coordinate system from the monodromy matrix through extraction of\nthe independent bases which span the space of the Halo orbit. To nullify diverging and\nconverging motion, we confine the relative motion to within the periodic subspaces. Two\ntypes of formations are studied in this thesis, natural loose formations and periodic loose\nformations with impulsive control. For natural formations, two modes of relative motion\nwithin these subspaces, long-term and short-term motions. In this study, the long-term\nmotion is approximated by deriving a discrete formulation of independent directions\nbased on the eigenvectors of the monodromy matrix, while for the short-term motion\nthe fundamental set solutions are modeled using Fourier series and additional linear func-\ntions. Since the size of the formation discussed is significantly smaller than that of the\nHalo orbit, the formation design method can fundamentally be stated as a process of\nlinearly combining these approximations to achieve the desired formation. Consequently,\nuse of this approach transforms formation design from a differential equation problem\ninto an algebraic one, and furthermore enables the long-term and short-term motion\ndesign problems to be handled either jointly or separately. To increase design degree of\nfreedom impulsive control is introduced to the formation problem. The use of single, two\nand three impulses are specially discussed in detail. Design examples, both for natural\nand with impulsive control formation are presented to demonstrate the validity of the\ndesign method.
