Generation of Meteorological Parameters for Tropospheric Delay on GNSS Signal [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2008
The GNSS (Global Navigation Satellite System) signal is delayed by the neutral atmosphere at the troposphere, so that the delay is one of major error sources for GNSS precise positioning. The tropospheric delay is an integrated refractive index along the

Assessment of ZTD Derived from COSMIC Occultation Data with ECWMF, Radiosondes, and GNSS [PDF]

open access: yesSensors, 2022
Global Navigation Satellite System (GNSS) signals generate slant tropospheric delays when they pass through the atmosphere, which is recognized as the main source of error in many spatial geodetic applications. The zenith tropospheric delay (ZTD) derived

European GNSS troposphere monitoring for meteorological applications [PDF]

open access: yesIOP Conference Series: Earth and Environmental Science, 2021
Abstract Near real-time GNSS double-difference network processing is a traditional method still used within the EUMETNET EIG GNSS Water Vapour Programme (E-GVAP) for the atmosphere water vapour content monitoring in support of Numerical Weather Prediction. The standard production relies on estimating zenith tropospheric path delays (ZTDs)

Detection of Alpine Foehn in GNSS-ZWD time series: An innovative application of GNSS Meteorology [PDF]

open access: yes, 2021
<p>The atmospheric delay experienced by a signal of the Global Navigation Satellite System (GNSS) is proportional to the water vapour content along the signal path. This fact is typically exploited in GNSS Meteorology by introducing GNSS derived atmospheric parameters like the Zenith Wet Delay (ZWD) in data assimilation schemes.
