摘 要：This paper focuses on the optimal design of the near space navigation network configuration concerning a specific target area.Optimal design not only ensure navigation service for specific area with high accuracy and low cost;but also enable all users in the target area to obtain a controlled precision.In this design,a double-layer Y configuration is adopted as the optimal basic unit.Adaptive algorithm and genetic algorithm are selected to detect the boundary of the configuration to realize the synchronization optimization of cost and accuracy.Combining with the working principle of aerostat in the stratosphere airspace,we design a platform dynamic trajectory and provide an algorithm optimization of layout for the partial users’worse precision in dynamic scene.The simulation results show that the optimal design method proposed in this paper can meet the configuration design requirements of the dynamic navigation network based on near space with different size area and different precision requirement.
