Using Direct Transcription to Compute Optimal Low Thrust Transfers Between Libration Point Orbits
نویسنده
چکیده
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-Moon libration points. 1 The Optimal Control Problem The primary focus of this paper is the presentation of efficient numerical methods to solve the optimal control problem. The goal is to choose the control functions u(t) to minimize the objective

Low-Thrust Optimal Orbit Raising with Plane Change
A new guidance scheme for the problem of Low-thrust transfer between inclined orbits is developed within the framework of optimal control theory. The objective of the guidance scheme is to provide the appropriate thrust steering program that will transfer the vehicle from an inclined low earth orbits to the high earth orbits. The presented guidance scheme is determined using Pontryagin’s princi...

The L1 and L2 libration points have been proposed as gateways granting inexpensive access to interplanetary space. The lunar libration points, in conjunction with the collinear libration points in the Sun-Earth system, may also become primary hubs for future human activities in the Earth’s neighborhood. The associated manifold tubes have been introduced by a number of researchers as the basis f...
متن کاملAas 13-334 Leveraging Resonant Orbit Manifolds to Design Transfers between Libration Point Orbits in Multi-body Regimes
Resonant orbits have been widely employed in mission design for planetary flyby trajectories (JEO) and, more recently, as a source of long-term stability (IBEX). Yet, resonant orbits have not been explored extensively as transfer mechanisms between non-resonant orbits in multi-body systems. To highlight the benefit of employing resonant orbits for transfers and given the increased interest in e...
متن کاملLow Thrust Cis-lunar Transfers Using a 40 Kw-class Solar Electric Propulsion Spacecraft
This paper captures trajectory analysis of a representative low thrust, high power Solar Electric Propulsion (SEP) vehicle to move a mass around cislunar space in the range of 20 to 40 kW power to the Electric Propulsion (EP) system. These cislunar transfers depart from a selected Near Rectilinear Halo Orbit (NRHO) and target other cislunar orbits. The NRHO cannot be characterized in the classi...
متن کاملIdentification of Halo Orbits for Energy Efficient Formation Flying
This contribution is concerned with the numerical simulation of spacecraft formation dynamics on Halo orbits around the Sun-Earth libration points. The circular restricted three-body problem (CRTBP) in rotating coordinates serves as the analytical framework. The primary goal is to identify regions in phase space in which the uncontrolled dynamics induces only very small perturbations on satelli...
