Abstract: Missing or incorrect consideration of azimuthal asymmetry of troposphere delays is a considerable error source in space geodetic techniques such as Global Navigation Satellite Systems (GNSS) or Very Long Baseline Interferometry (VLBI). So-called horizontal troposphere… read more here.

DOI: 10.1109/tgrs.2022.3188336
Abstract: The ionospheric mapping function (IMF) is fundamental in retrieving total electron content (TEC) from observations onboard low earth orbiting (LEO) satellites, as well as the receiver differential code bias (DCB) estimation. Most IMFs apply the… read more here.
