Abstract :
In this paper, we consider the problem of establishing front-to-front sensor lock (FFSL) between two spacecraft when the relative trajectory is not constrained to a plane that is normal to the sunline. We then provide a detailed three-dimensional analysis of the basic formation initialization algorithm, and introduce projection operations in which establishing FFSL in 3D is effectively reduced to analysis in a plane. Finally, we provide easily testable conditions whether in-plane searching be sufficient to guarantee FFSL and discuss a situation where in-plane search fails.
