A method for unpowered space robot safety rendezvous, with non-cooperative spacecraft

Aiming at rendezvous path planning of free floating space robot (the chaser satellite) in outer space, the path planning method to ensure safe approaching the non-cooperative space target based on the orbit mechanical equation is proposed. The whole rendezvous path planning strategy and safety principle of rendezvous path planning in ultimate approaching stage of free floating space robot are researched; Based on orbit mechanical equation, the moving ellipse locus of free floating space robot is generated using the safety principle to approach the non-cooperative space target in ultimate approaching stage. The method realizes that the space robot system approaches the spinning non-cooperative space target in free floating work mode, and the robot can escape safely when the subsequent work could not be normally completed.
