Abstract: CubeSats are miniature functional satellites The increasing interest in CubeSats has uncovered the potential for planetary missions Besides, CubeSats is an excellent educational platform. The preliminary attitude control system is designed and the corresponding hardware is built using commercial products for a lunar mission employing a CubeSat constellation to provide positioning service for landers/rovers on the far side of the moon At the same time, the basic frame and necessary subsystems including the structure, power and onboard computer subsystems, and the attitude experiment platform are constructed Based on the hardware platform, the control model is deeply understood through measuring damping coefficients by experiments A PD control method is designed to control the attitude The numerical and physical simulation results match well, and the CubeSat system achieves accurate attitude maneuver.

Key words: university CubeSats, CubeSats in deep space, system design, attitude control, CubeSats hardware system
