Research on performance of BeiDou global broadcast ionospheric delay correction model (BDGIM) of BDS-3
Acta Geodaetica et Cartographica Sinica
On June 23, 2020, the last BDS-3 satellite was launched, which means that the China BDS finished its global system construction. The BDS-3 adopts a new generation global broadcast ionospheric delay correction model (BDGIM) for the single frequency ionospheric delay correction. This paper describes the performance of BDGIM during the period before and after the establishment of the BDS-3 system, in terms of the accuracy of ionospheric delay correction, BDS single-frequency pseudorangedoi:10.11947/j.agcs.2021.20200421 doaj:2c9a9c4766fd41bea3d0c6a9553a1dc4 fatcat:ewr3tjvqnbavxnr7rvilp7gbre
