“…This rotation matrix is defined to be the one that describes the orientation of the spacecraft-fixed reference frame F C with respect to the station-fixed reference frame F S . In the present context, the mathematical space SOp3q is regarded as a Lie group with tangent bundle TSOp3q and Lie algebra sop3q (see, e.g., [31,32]).…”

“…The quantities R 0 P SOp3q and Ω 0 P sop3q denote initial attitude and angular speed, respectively. Details on the derivation of the above equation may be found in the companion paper on spacecraft reorientation [32].…”

“…More sophisticated attitudinal control strategies may certainly be put into effect, taking into account, for example, specific unwanted and wanted directions. Such control problem was discussed in details in the companion paper [32] dedicated to the reorientation of a spacecraft under directional constraints. This sophisticated problem was, however, not considered in the present contribution.…”

The aim of this research paper is to propose a framework to model, simulate and control the motion of a small spacecraft in the proximity of a space station. In particular, rendezvous in the presence of physical obstacles is tackled by a virtual potential theory within a modern manifold calculus setting and simulated numerically. The roto-translational motion of a spacecraft as well as the control fields are entirely formulated through a coordinate-free Lie group-type formalism. Likewise, the proposed control strategies are expressed in a coordinate-free setting through structured control fields. Several numerical simulations guide the reader through an evaluation of the most convenient control strategy among those devised in the present work.
