摘要
Abstract
The time-lapse network covering the whole world based on the links between navigation satellites,this paper studies the optimization of contact design plan of satellites.Firstly,the to-pology model of navigation satellite constellation which is dynamic is established,and the princi-ple that the information path and network node load are uniquely determined by the network to-pology,under the specific routing strategy,and the asymmetric characteristics of navigation sat-ellite network traffic are analyzed.Then,based on the navigation constellation model,a load bal-ancing network topology optimization method based on the obj ective evaluation function is pro-posed.The calculation steps of the chain constructing optimization method are formed.Finally, the network delay and access capacity are used as indicators to verify the performance of planning method for load balancing.The simulation results prove the feasibility of the optimization method based on load balancing,which is of reference value to the management and operation of constel-lation of global navigation system.关键词
