    Rendezvous and Proximity Operations at the Earth-Moon L2 Lagrange Point: Navigation Analysis for Preliminary Trajectory Design
    (2014-02-20) Mand, Kuljit; Spanos, Pol D.; Meade, Andrew J; Dueñas-Osorio, Leonardo; Woffinden, David C
    The Earth-Moon L2 point has attracted attention for potential space exploration, and rendezvous is required for several critical operations. The relative dynamics at this location are vastly different from locations rendezvous are typically completed. Rendezvous trajectories must be revised or created anew and a crucial element to consider for any trajectory are the navigation requirements. Working within an LVLH frame, Linearized-Relative (LR) targeting is developed. LR targeting provides the means to create three preliminary trajectories: an L2 adaption of the Double Co-Elliptic, the Line-of-Sight Corridor, and the Line-of-Sight Glide. Through extending the capabilities of linear covariance analysis, the navigation requirements necessary for rendezvous and docking at L2 are derived. These navigation requirements are subsequently utilized for a sensor suite analysis, and an optimal sensor suite for each trajectory is determined.
