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

Kinematic ZTD Estimation from Train-Borne Single-Frequency GNSS: Validation and Assimilation
Remote Sensing, 2021 Water vapour is one of the most important parameters utilized for the description of state and evolution of the Earth’s atmosphere. It is the most effective greenhouse gas and shows high variability, both in space and time.
