摘要
根据香港GPS永久跟踪站的长期GPS观测资料，估计出了香港地区电离层垂向电子含量，并分析了垂向电子含量的周日变化规律，对建立香港地区实用的电离层模型有重要的指导意义。
In this paper,an assessment of measured ionospheric vertical total electron content(VEC) in Hong Kong area based on dual GPS data which are from the Hong Kong DGPS universal reference station is presented. The variances of VEC on four seasons in one year aregiven, and the variant regularity of VEC in one day is also analyzed. It is favorable forbuilding a practical model of ionosphere in Hong Kong area.
