“…With the expansion of human space travel, rendezvous and docking technology in spacecraft have become indispensable for a variety of space activities [1,2]. When conducting docking activities in space, active and passive docking mechanisms must attain and maintain high levels of reliability and stability.…”

The design and analysis of a new type of three-jaw docking mechanism capable of space rendezvous and docking are presented. In addition, a composite docking test platform capable of both vertical and horizontal docking is created. On the basis of kinematics theory, a global coordinate system is built, and the attitude error is assessed based on the error angle. On the basis of dynamic theory, the multi-body dynamic differential equation of the composite docking platform is derived, and the impact-induced interaction state of the locking pawls is studied. The simulation software is then used to jointly simulate the test platform and the docking mechanism under the two conditions of frontal and oblique docking, and to analyze the attitude law caused by the change of docking impact force. This provides a solid foundation for future research into the application of space rendezvous theory to small spacecraft.

“…One way to improve the confidence level in the success of the docking phase is to adopt an effective strategy to control the relative distance between the Target and Chaser. In this sense, the problem related to the docking maneuvers is deeply investigated in literature for big satellites [15][16][17], and the docking of spacecraft with the ISS is almost a "routine" operation both for cargo and manned vehicles [18][19][20]. From the analysis of the solutions for a big spacecraft, it is possible to identify how the robustness of the control and the maneuver authority together with the execution time and, in case, the control effort are fundamental aspects that the controller must satisfy.…”

The release and retrieval of a CubeSat from a big spacecraft is useful for the external inspection and monitoring of the big spacecraft. However, docking maneuvers during the retrieval are challenging since safety constraints and high performance must be achieved, considering the small dimensions and the actual small satellites technology. The trajectory control is crucial to have a soft, accurate, quick, and propellant saving docking. The present paper deals with the design of a tracking model predictive controller (TMPC) tuned to achieve the stringent docking requirements for the retrieval of a CubeSat within the cargo bay of a large cooperative vehicle. The performance of the TMPC is verified using a complex model that includes non-linearities, uncertainties of the CubeSat parameters, and environmental disturbances. Moreover, 300 Monte Carlo runs demonstrate the robustness of the TMPC solution.
