The invention discloses navigation constellation optimization design platform and method based on a decomposition thought and a particle swarm fusion method, wherein the platform comprises a man-machine interaction module, a constellation configuration module, a constellation performance module, a constellation cost module, a multi-target integration module, a Combined algorithm module, a constellation performance analyzing module, a visualization module and a report generation module. The method comprises the following steps of: firstly putting forward a navigation constellation design scheme by a user; then setting a performance index and calculating by utilizing a multi-target improved method based on the decomposition thought and particle swarm fusion or multi-method combination; and finally analyzing and displaying a processing result. The method analyzes the characteristics of various constellation designs, overcomes the shortages of the traditional method, optimizes the constellations under the condition of virtual simulation and simultaneously and creatively adopts the decomposition based multi-target improved method to the navigation constellation optimization designs, thereby simplifying the design process, also avoiding the problems of overlong calculation time and partial optimization; in addition, the platform has expandability.
Description
technical field [0001] The invention belongs to the field of constellation optimization design, and in particular relates to a navigation constellation optimization design platform and method based on a decomposition idea and a particle swarm fusion method. Background technique [0002] At present, with the rapid development of navigation technology, all countries in the world are scrambling to study their own navigation and positioning systems, and China is also stepping up the establishment of its own "Beidou II" global positioning system. However, with the global coverage of the navigation and positioning system, the independent working mode of a single satellite can no longer meet the ground coverage requirements. The navigation satellites must work together in a constellation network to meet the coverage requirements. Therefore, designing a reasonable navigation constellation is the key to achieving global positioning. key. At the same time, with the continuous launch ...
