Abstract
Because of miscellaneous pointing tasks, means and constraints, various attitude pointing scenarios for three-axis stabilized deep-space explorer were needed. Moreover, the reference attitude command must be imported from out of the control loop, considering the constraint to attitude sensors selection due to deep-space environment. The introduction of attitude guidance is then essential. Based on vector algebra and vectorial kinematics, this paper derived an onboard real-time desired attitude and rate computation method. The guidance algorithm was tested on multimode attitude control mathematical simulation and demo for small-body exploration. The derived attitude control command is generic, simple, and convenient for onboard implementation, and will fulfill the challenge brought by the variety of pointing scheme.
