Abstract
  Design of launch vehicle (LV) trajectory is among the problems in which the use of optimization is of high significance. Implementing optimization using optimal control problem leads to a two point boundary value problem (TPBVS) that can be solved only numerically. On the other hand, development of optimal ...  Read More

Optimal Low Thrust Orbit Transfer Using Direct Collocation Method

R. Jamilnia; A. Naghash

Volume 1, Issue 2 , December 2008, , Pages 35-42

Abstract
  In this paper, a new approach is proposed for solving the problem of optimal low thrust orbit transfer. In this approach, the problem of trajectory optimization of optimal orbit transfer is defined by modified equinoctial orbital elements. For solving this problem, direct collocation method, that is ...  Read More
