| 摘 要： | 利用单站GPS观测数据对GPS硬件系统延迟作出修正，得到较精确的电离层总电子含量。根据Chapman电离层理论，建立电离层模型，利用遗传算法优化选择电离层关键参量，反演得到接收机上空电子密度剖面，结果表明：该方法用于太阳活动高年白天电子密度剖面反演效果优于国际参考电离层。

| Abstract: | Vertical total electron content is obtained after GPS system hardware error being estimated using single ground-based GPS receiver observation data Based on Chapman theory of ionosphere and statistic results of observation data,a simple ionosphere electron density profile is proposed here,and the key ionosphere parameters are optimized by genetic algorithm.The retrieving results show that this method is better than IRI model during daytime in solar activity high year. |
