Evaluation of Spaceborne GPS Data Quality and Higher-order Ionospheric Delay Effects on SWARM Precise Orbit Determination in the Severe Geomagnetic Storm on April 23–24, 2023

Geomagnetic storms significantly enhance ionospheric electron density, thereby severely influencing ionospheric delay and degrading the quality of spaceborne GPS observations for low Earth orbit satellites. Traditional study rarely focuses on precise orbit determination (POD) during geomagnetic storms using reduced dyn...
