Analysis and validation of different global ionospheric maps (GIMs) over China
Y Xiang, Y Yuan, Z Li, N Wang - Advances in space research, 2015 - Elsevier
We assess four different global ionospheric maps (GIMs) over the area of China based on
internal consistency (Wrt GNSS-derived total electron content (TEC)) and external accuracy
(Wrt Topex/Poseidon-derived TEC). The results of relevance would serve as references for
single-frequency GNSS Positioning, Navigation and Timing (PNT) users to flexibly
determine which GIM is to be based on to get the more efficient ionospheric delay
corrections service. Performance of these four GIMs sources are validated during high level …
