Assimilation of GNSS Zenith Total Delay in NAVGEM

Journal of Geophysical Research: Atmospheres, 2023
AbstractA new data source from ground‐based stations that track global navigation satellite system (GNSS) transmitters has been implemented in the Navy Global Environmental Model (NAVGEM) with the NRL Atmospheric Variational Data Assimilation System‐Accelerated Representer.

Assessment of GNSS Zenith Total Delay Estimation Using Smart Devices

ION GNSS+, The International Technical Meeting of the Satellite Division of The Institute of Navigation, 2019
Global Navigation Satellite System (GNSS) have been routinely used in the last decades to estimate water vapor content in the lower part of the atmosphere. Water vapor measurements have been successfully integrated in Numerical Weather Prediction (NWP) models, showing a positive impact on the forecast of rain events.
