DESIGN METHODS FOR LOW-ENERGY LOW-THRUST TRANSFER ORBIT BETWEEN PARKING ORBITS AROUND JOVIAN MOONS

propose a novel method for low-energy low-thrust transfer orbit between parking orbits around Jovian moons. Using a "halo-like section", the manifold is simply parameterized and patched by the multibody Lambert algorithm based on collocation method. Then by using the global optimization algorithm, a preliminary optimization result is obtained with minimal fuel consumption. The transfer orbits with lowthrust propulsion are optimized and designed by the homotopic method with multi-body environment and the multi-circle transfer orbit design method with fixed perigee height. The proposed method may be applied to transferring orbit design between other celestial bodies. In summary, we have proposed new design ideas and methods for low-energy low-thrust transfer orbit with multi-body environment.
