Research on the Dynamic Configuration of Air-Based Pseudolite Network

摘要

To realize the adaptive adjustment of the air-based pseudo-lite (PL) navigation augmentation network, a dynamic configuration method for the airbased PL network deployment is proposed. By surveying and defining the indicators describing the performance of navigation augmentation network, based on the basic needs of navigation enhancement task, an objective function is designed for the optimization deployment of the air-based PLs. Using particle swarm optimization algorithm (PSO) for the fine search of the objective function of the airbased PL optimization deployment in multi-dimension, the dynamic optimal deployment is obtained. The simulation results show that, the proposed method could keep the navigation performance optimum, in the case of navigation enhancement service region changing or the local PL being interfered.
