This article presents a new method for accurately estimating the height and zonal drift velocity of ionospheric irregularities, based on crossed signal paths from two BeiDou geostationary satellites to two ground-based receivers. The ratio of distances between different signal paths varies with altitude, and irregularities’ height can be identified according to observed arrival times of ionospheri...Show More
In this study, we characterized the variations in ionospheric irregularities and medium-scale traveling ionospheric disturbances (MSTIDs) simultaneously at mid-latitudes over central China based on high-fidelity observations of the total electron content (TEC) from a Beidou geostationary satellite and explored their quantitative relationships during 2016–2017. Ionospheric irregularities generally ...Show More
The uncertainty of differential code bias (DCB) is one of the main error sources in the low Earth orbit (LEO) based total electron content (TEC) retrieval, whereas the derivation of the LEO DCB is not systematically studied. In this paper, we propose an improved DCB estimation method (ZERO method) based on the assumption that the LEO-based TEC can reach zero and also optimize the parameter configu...Show More
