Title: An Explicit Guidance Strategy in Halo-to-Halo Transfers
Abstract: An explicit guidance strategy is developed in order to compensate for the perturbations in a real model or a simulation model. The main idea is to add control at equally spaced time points according to the calculation of the required velocity,which is the key point of the method. The required velocity is computed by solving a three-body Lambert problem (3BLP). The presented method is applied to the Earth-Moon L1 Halo-to-Halo transfer problem where the nominal orbit is obtained from CR3BP,and the simulation is performed taking the bicircular model (BCM) as perturbation model including the solar gravity. It can be easily extended to other systems and transfer types,as well as various dynamics models. Results show that the approach can successfully maintain control of the vehicle and a small amount of propellant are required.
