An Introduction To Libration Point Orbits
The “three-body problem”, which considers a system composed of three gravitating bodies rather than the two bodies of the classical Keplerian model, has been studied extensively for several hundred years. Investigations of the three-body problem have inspired many new developments in the mathematical theory of differential equations and dynamical systems. From a more practical standpoint, the s...
متن کاملDesign of transfers from Earth-Moon L 1/L2 libration point orbits to a destination object
Kakoi, Masaki Ph.D., Purdue University, May 2015. Design of Transfers from EarthMoon L1/L2 Libration Point Orbits to a Destination Object. Major Professor: Kathleen C. Howell. Within the context of both manned and robotic spaceflight activities, orbits near the Earth-Moon L1 and L2 libration points could support lunar surface operations and serve as staging areas for future missions to near-Ear...
متن کاملUsing Direct Transcription to Compute Optimal Low Thrust Transfers Between Libration Point Orbits
The direct transcription method has been used to solve many challenging optimal control problems. One such example involves the calculation of a low thrust orbit transfer between libration point orbits. The recent implementation of high order discretization techniques is first described and then illustrated by computing optimal low thrust trajectories between orbits about the L1 and L2 Earth-Mo...
متن کاملthe use of appropriate madm model for ranking the vendors of mci equipments using fuzzy approach
abstract nowadays, the science of decision making has been paid to more attention due to the complexity of the problems of suppliers selection. as known, one of the efficient tools in economic and human resources development is the extension of communication networks in developing countries. so, the proper selection of suppliers of tc equipments is of concern very much. in this study, a ...
15 صفحه اولProspects for the Use of Space Robots in the Neighbourhood of the Libration Points
This paper is devoted to the navigation tasks for space robots operating in the neighborhood of unstable libration points of the Earth-Sun system in the near-Earth space. The motion of robot in space is examined under a circular restricted three-body problem. The possibility of a space robot maneuvering in the near-Earth space with return to the neighborhood of a collinear libration point and s...
