Utilization of Signal Global Navigation Satellite System (GNSS) for Meteorological [PDF]

open access: yesInternational Journal of Environment, Agriculture and Biotechnology, 2021
In this study, I show that microwave signals emitted from satellites and received by the GNSS system can be utilized for meteorological purposes, such as heavy rain in Indonesia, using open-source software goGPS. Comparison of the gradient of the North and East atmospheric delays between goGPS, IGS, and UNR. The correlation of the results of goGPS with

Applying Malawi Continuously Operating Reference Stations (CORS) in GNSS Meteorology

open access: yesSouth African Journal of Geomatics, 2022
Global Navigation Satellite System (GNSS) signals in the L-band are affected by the non-dispersive neutral atmosphere. Regardless of their center frequency, the L-band code and phase observations are affected by the same measure of delay. GNSS receivers play a significant role in quantifying the zenith tropospheric delay (ZTD) from satellite signals ...

GNSS Meteorology and Tropospheric Paramteres Investigation

open access: yesGeodetski glasnik, 2015
Troposphere plays crucial role for geodetic comunity, which can primarly be seen in its influence on GNSS observations. At the same time, troposhpere is the place where almost all hidrometeorological phenomena that effect our everyday life occure. Scientists have found a way to use systematic influence that troposphere has on GNSS signal and turn it ...

Research on the Meteorological Prediction Algorithm Based on the CNSS and Particle Swarm Optimization

open access: yesComplexity, 2021
Considering that the global navigation satellite system (GNSS) has the influence of positioning and atmospheric signals from time to time in meteorology, errors caused by moisture, and so on in the effect of the propagation path, these factors have led ...
