Application of NeQuick2 in Space-Borne GPS Single-Frequency Real-Time Orbit Determination
Abstract In this paper, a three-dimensional ionosphere model-NeQuick2 is introduced. We firstly evaluate the precision of Klobuchar and NeQuick2 using global ionosphere maps and then perform the SADODS simulation experiments in different methods, using different ways to eliminate the influence of ionosphere. The results demonstrate that the orbital accuracies using NeQuick2 are improved by 0.2 m compared to the traditional method using modified Klobuchar.
Key words :
