Displaced Sun-Synchronous orbit control scheme for sailcraft

Displaced Sun-Synchronous orbit (DSSO) is names as the orbit with the same orbital parameters but the paralleled orbital plane with the Sun-synchronous orbit. Employing the solar pressure and the universal gravitation, the orbit could suspend. In this paper, the principle corresponding to orbit suspension is deduced, the orbit injection scheme is presented and the orbit keeping scheme is proposed. Simulation results indicate that the scheme is effective and the sailcraft could enter into the displaced Sun-synchronous orbit by employing the solar pressure and the universal gravitation.
