Abstract
  In this research, the problem of optimal trajectory design of an upper stage is considered for satellite injection into Geostationary orbit in 3-Dimensional space. The optimal multi-burn trajectory is obtained based on Euler-Lagrange theory with minimum fuel consumption criteria. Instead of using switch ...  Read More

Volume 1, Issue 2 , December 2008, , Pages 43-50

Abstract
  In this study, optimal low-thrust spacecraft trajectories are obtained by time-domain finite element method. Equations of motion are expressed in state-space form. The performance index is considered as minimum time. The problem has been formulated through the variational approach. The time-domain finite ...  Read More
