Galileo卫星导航系统广播NeQuick模型及其参数拟合
Simulation of NeQuick Parameters of Galileo Satellite Navigation System
摘要
Abstract
The simulation model of Galileo ionospheric parameters based on IGRF is proposed to solve the problem that ionospheric parameters estimation is related to geomagnetic coordinates. Using IGRF, the geomagnetic elements of the geomagnetic field and the Electron Density can be computed at a given location and time, sequentially, the ionospheric parameters of Galileo can be calculated. The simulation results show that the ionospheric delay calculated by this model is consistent with the value observed by IGS, and the precision is higher than those by other models, which proves that the high precision simulation of the Galileo ionospheric parameters is realized.关键词
