Modeling and control on fast fly around from any orientation in space and line of sight pointing is researched in this paper. Defining fly around reference and desired attitude coordinate system, the control problem is transformed to XY plane motion and attitude tracking of rotation around Y axis in desired attitude coordinate system. Through introducing desired relative position vector, the universal model of general relative motion and line of sight pointing is established. And the corresponding control law is designed. The case of noncoplanar fast circular fly around is simulated, and in the simulation, control commands are distributed dynamically by using the redundant thruster deployment pseudo inverse algorithm and introducing. The solution is validated through simulation.
