The article presents a system design concept for the momentum management with double gimbaled solar arrays on nano-satellites, where the two functions momentum control and optimal power generation are integrated to save mass. Momentum unloading is proposed to be performed with a double gimbaled solar array by using the gravity gradient torque. It is demonstrated that the power generation can be significantly increased compared to single axis arrays although combining two functions on the solar array. Exploitation of this method can significantly reduce the system cost and complexity by abandoning redundant thruster systems and not depending on expendables. Adaptive structures are proposed for the realization of the gimballingmechanism to reduce mass and mechanism complexity. The momentum unloading is based on a time-optimal bang-bang control law. The feasibility of the concept is demonstrated by simulation results which have been derived for different satellite configurations and LEO parameters.
