Design of Ganymede-Synchronous Frozen Orbit around Europa

A Ganymede-synchronous frozen orbit around Europa provides a stable spatial geometry between probe and Ganymede lander, which facilitates the observation of data transmission probes. However, third-body gravitation perturbation continues to accumulate affect long-term evolution probe. In this paper, relative with respect is considered accurately capture potential. The orbital behaviors under non-spherical Jupiter are studied based on double-averaging framework. Then, initial conditions developed. station-keeping maneuver was performed maintain elements achieve behaviors. numerical simulation showed that consumption for maintenance acceptable.
