abstract = "The goal of this study is to evaluate the influence of the
gravitational attraction of the Sun, and the Galilean moons,
during orbital maneuvers of a spacecraft orbiting Jupiter.
Initially ideal thrusters, capable of applying infinite magnitude
of the thrust, were used. Thus, impulsive optimal maneuvers were
obtained by scanning the solutions of the Two Point Boundary Value
Problem (TPBVP) for various values of transfer time in order to
select the impulsive maneuver of minimum necessary velocity
increment. Then, the selected maneuver was simulated considering a
more realistic model of the propulsion system. In fact is not
possible to accomplish an impulsive maneuver. Thus, the orbital
maneuver must be distributed in a propulsive arc around the
position of the impulse given by the solution of the TPBVP. In
this arc was used a continuous thrust, limited to the capacity of
the thrusters, with automatic correction of the trajectory.
However the effect of the propulsive arc is not exactly equivalent
to the application of an impulse. The evaluation of the difference
between these approaches is extremely relevant in the mission
analysis and spacecraft design of the trajectory control system.
Therefore, the influence of the capacity of thrusters in the
trajectory was evaluated for a more realistic model instead of the
ideal case represented by the impulsive approach.",
