顾及f~3项的电离层延迟模型

Ionospheric Delay Model Containing f~3 Term

    摘要
  • 摘要: 给出了顾及f3项时消除电离层延迟的两种方法:用三频观测值来消除电离层延迟,直接用地磁场模型来计算f3项。提出了一种用一个三次曲面来拟合30°×40°的区域内的场强H的简化算法。用两种方法求得的电离层延迟之差小于0.5 mm。

     

    Abstract: Two methods to eliminate the ionospheric delay containingf3term are given.The first method is to eliminate ionospheric delay with triple-frequency observations.The second method is directly calculate thef3term.A simplified method is proposed that a three order polynomials is used to fit the geomagnetic field intensity of a 30°×40°area,which can achieve a rather good result.By comparison,the difference of the ionospheric delay between the calculated results by the two methods is less than 0.5 mm.
