Abstract
Existing methods for calculation of ionospheric delay was analyzed:observation error was amplified distinctly, and the information of geomagnetism and ionosphere was not utilized in triple-frequency combination method; Integral computation was no rigorous enough in traditional direction method, and the applicable area was limited. A new method to calculate the ionospheric delay was proposed in this paper: revising the direct calculation with the results in multi-frequency combination method. The information of geomagnetism and ionosphere was well used in the new method. Furthermore, the consistency was ensured same with triple-frequency combination method. A new thinking was proposed for calculation of ionospheric delay.
