[297614] Real time tropospheric delay measurements for time and frequency transfer using GNSS
Autores: Luiz Paulo da Silva Damaceno, V. S. Tavares
Resumo: Time and frequency transfer using GNSS is affected by disturbances in the link between satellite and receiver. This degrades the time solution of the receiver, implying in erroneous local clock evaluation and in some cases, wrong clock calibration. In modern receivers it is possible to measure the ionospheric delay using dual frequency observations, but the tropospheric delay in the way is still being modelled by receiver altitude and satellite elevation. In this text an evaluation of the effect of updating the default model with real-time tropospheric delay measurement using Temperature, Humidity and Atmospheric pressure data.
