ABSTRACT=The paper describes the development of a framework capable of addressing some fundamental3
issues in the analysis of proximity operations between two spacecraft that are operating within a4
three-body model defined by two primaries and the spacecraft themselves. The main objective is5
to enable the capability of analysing dynamic and control issues during an automated rendezvous6
between a vehicle and a passive space station orbiting around the Earth - Moon L2 Lagrangian7
point on a near rectilinear halo orbit. The paper presents first a restricted three body model8
dynamics and a nominal approach trajectory, followed by an analysis of the influence of assumed9
actuators and sensors. Critical aspects such as selected failures are investigated, in order to10
ensure passive safety of the mission using impulsive maneuvers. An example of closed loop11
guidance in the near range is also presented and the overall performance are validated with an12
Ephemeris model available in the literature
