Penentuan Zenith Tropospheric Delay Menggunakan Data CORS GNSS [PDF]
, 2021 Signal propagation from the GNSS satellite in the form of electromagnetic waves to the receiver through the atmospheric medium causes atmospheric bias, both ionospheric and tropospheric bias caused by changes in the medium in the atmospheric layer, and ...

The effect of UNBabc mapping function modification to GPS tropospheric delay [PDF]
, 2008 Tropospheric delay refers to the refraction of the Global Positioning System (GPS) signal as it passes through the neutral atmosphere from the satellite to the earth, which causes longer distance traveled by the signal.

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.Abstract The zenith total delay (ZTD) retrieved from 5G communication base stations represents a novel observation source for numerical weather prediction (NWP), leveraging the extensive global deployment of 5G infrastructure. In this study, the direct assimilation of 5G‐ZTD observations into a high‐resolution NWP system was accomplished for the first ...

Assessing Co‐Located NISAR and Sentinel‐1 Observations for Atmospheric Characterization
Journal of Geophysical Research: Atmospheres, Volume 131, Issue 19, 16 October 2026.Abstract Tropospheric delay remains one of the largest sources of uncertainty in repeat‐pass Interferometric Synthetic Aperture Radar (InSAR) measurements, while accurate three‐dimensional deformation retrieval continues to be limited by the geometry of current spaceborne SAR systems.
