摘　　要：根据空基导航信号增强平台的工作原理设计了组网优化评价指标;然后简单介绍了遗传算法的基本原理,对空基增强平台的空间位置进行了二进制编码;最后采用通用的遗传算法对空基导航信号增强平台空间分布进行优化搜索。仿真实验结果证明该算法能够对空基导航信号增强平台进行有效布置,覆盖范围内导航服务误差分布合理,并且能够根据实际要求对空基平台进行优化调整。The paper study the optimization problem of formation flying navigation augmentation platforms. At first an evaluation criterion was set for the optimization based on the working principles of formation flying augmentations. The basic theory of genetic algorithm was introduced and the augmentation platform position was encoded with binary code. The optimum position of formation flying platforms was searched with general genetic algorithm. The simulation results show that the method pro- posed by this paper can dispose the formation flying platforms effiently. The position error distribution in the service area is valid and the position of formation flying platforms can adjust with the different requests.
