An online virtual maintenance path search method based on A* algorithm

With the increasing of spacecraft launch missions, the number of spacecraft module maintenance tasks also increases, so the path planning link plays a crucial role in the online virtual module maintenance task operation of spacecraft. Since A large amount of qualitative/quantitative method analysis is required in the process of writing the traditional maintenance report, the A* algorithm is adopted in this paper to search the path for the on-orbit module maintenance task of the spacecraft. Firstly, the abstract model of spacecraft in orbit cabin is built with unity 3D, and then the search point is controlled to move to the target point based on C#. Finally, in the process of gradually adjusting C# parameters, the optimal parameters are obtained and the path planned by A* algorithm is displayed. Simulation results show that this method can plan an efficient and safe maintenance path in virtual maintenance environment.
