The optimal path planning of attitude maneuver for space station with complex geometry constraints using onlyControl Moment Gyroscopes (CMGs) is investigated. Attitude is described by Modified Rodrigues Parameter (MRP),and the dynamic model of space station and CMGs momentum is developed. The geometry constraints and CMGsperformance constraint need to be satisfied during the maneuver. Gauss pseudospectral method (GPM) is applied totransform the optimal control problem (OCP) into a nonlinear programming problem (NLP). A two-step solvingstrategy which combines different performance index is proposed the large-angle optimal attitude path whichsatisfies the complex geometry constrains is obtained using the proposed method, it is shown that the CMGsmomentum constraint satisfied for the planned path while the eigenaxis path maneuver violates it. Also, the plannedpath uses less energy than the eigenaxis maneuver. The numerical simulation results indicate that the method ispracticable and effective.
