Abstract

Non-coplanar circular orbital transfers based on the invariability of descending nodical local time is studied in this paper. Based on minimum principle, both of the thrust direction and magnitude are optimized, regarding minimum total impulse and final position and velocity constraints as the performance index on the assumption of fixed transfer time and continuous thrust. The optimal transfer orbit is then obtained using conjugate gradient method. As transfer time is given, a special initial condition for orbital transfers is determined, which ensures the invariability of descending nodical local time. The validity of orbital transfer strategy adopted has been verified by simulation results.
