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

New applications and opportunities of GNSS meteorology [PDF]
, 2020 Water vapor content of the atmospheric low layer, up to about 18 km, known as troposphere or neutral atmosphere, affects GNSS (Global Navigation Satellite System) signals by lowering their propagation velocities with respect to vacuum.

European GNSS troposphere monitoring for meteorological applications [PDF]
IOP 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)
