Improving the quality of real-time GNSS zenith troposphere delay models
The troposphere is a major error source in Global Navigation Satellite System (GNSS) positioning and a limiting factor for interferometric synthetic aperture radar (InSAR) observations. However, the remote sensing of the troposphere with GNSS, called GNSS meteorology, provides information about the troposphere of spatial and temporal resolutions higher than any other troposphere sensing technique. The accuracy and timely provision of the main product of GNSS meteorology, the zenith troposphere delay (ZTD), is limited by the quality and latency of satellite orbit and clock products. The EU-funded ReS4ToM project aspires to develop a high-quality real-time GNSS model of the troposphere, by combining multiple recent advancements in GNSS. The project aims to support meteorological forecasting and geodetic techniques.
