| With the scale of aerospace action expanding, it's necessary to build a full-functional and integrated computer system for spacecraft's motion analyzing, which has the characteristics of GUI and 3D scene simulating and validating. According to the system's requirements, the theory and technology of distributed object system is applied to design and develop this system in order to make the best of its natural advantage. To determine the design, the conception of the distributed object system is simply summarized, through discussing conception of distributed system, and comparing several kinds of architecture and technology of distributed object system. The route of designing based on object's form and content is then concluded.All of the analyzing and computing procedures are summarized based on the analyzing of spacecraft motion and processing of visualization. The pipeline and parallel architecture is deduced by refering current distributed visualization technology. In the view of that the distributed object in the distributed object system has same position as the process in the distributed system, this system is designed according to the requirements and utilizing the pipeline and parallel architecture, and is supplemented and completed by the .NET technology. It satisfies the needs of performance, system requirement and software system quality. |
