Abstract

Abstract

The separation and reconfiguration of stacked satellites in orbit is an effective technique for constructing large space structures. The natural coordinates formulation is used to establish the dynamic equations for stacked satellite systems, which has the advantage of facilitating the handling of fixed constraints between satellites. Suitable strategies for autonomous assembly separation and assembly are devised. A spin separation method is employed to achieve collision-free separation of satellites, while PD control and the potential function is utilized for satellite assembly. Additionally, an optimization algorithm is employed to calculate the minimum distance between satellites, enabling precise determination of the potential function's magnitude. By implementing these methods in simulations, the complete process from separation of stacked satellites to segmented assembly is realized, which confirming the effectiveness of the proposed separation and assembly strategies.
