Abstract Without additional attitude and orbital control systems, such as thrusters, solar-sail trajectories are controlled by the orientation of the sailcraft. The sail attitude is employed to target the sailcraft to some future state along the reference trajectory. In a “turn-and-hold” strategy, the attitude profile consists of at least three orientations between an initial and future, target state along the trajectory. Because of orbit-knowledge, control, and turn-modeling errors, a look-ahead control strategy is generated, one in which only the first turn from the profile is performed, and then a new profile is constructed based on updated orbit knowledge. The initial hold intervals, along with the number of turns, used to generate an attitude profile is automatically adapted to improve convergence of the algorithm. This technique is generally successful when applied to reference trajectories generated in an Earth–Moon–Sun ephemeris regime.
