基于Bernese软件的局部电离层TEC模型参数估计

Local Ionospheric TEC Model Parameter Estimation Based Bernese Software

介绍了Bernese软件中采用的电离层模型,即多项式模型和球谐函数模型,利用其IONEST及GPSEST模块,采用双频GPS观测数据估计得到电离层TEC模型参数,实现了局部电离层电子含量建模。

As a high demand, high precision and high flexibility of GNSS data processing software, Bernese has been widely used in various agencies because of its accurate mathemat ical model, a detailed calculation process parameter control, powerful automated batch pro- cessing and other features. The article describes the ionospheric model used in Bernese soft ware, namely polynomial model and spherical harmonic function model, and use its IONEST and GPSEST module to estimate ionospheric TEC model parameters to achieve a local iono-spheric electron content modeling by using dual-frequency GPS observation data.
