Stability of CubeSat Clocks and Their Impacts on GNSS Radio Occultation [PDF]

Remote Sensing, 2022
Global Navigation Satellite Systems’ radio occultation (GNSS-RO) provides the upper troposphere-lower stratosphere (UTLS) vertical atmospheric profiles that are complementing radiosonde and reanalysis data. Such data are employed in the numerical weather prediction (NWP) models used to forecast global weather as well as in climate change studies ...

The power of vertical geolocation of atmospheric profiles from GNSS radio occultation. [PDF]

J Geophys Res Atmos, 2017
AbstractHigh‐resolution measurements from Global Navigation Satellite System (GNSS) radio occultation (RO) provide atmospheric profiles with independent information on altitude and pressure. This unique property is of crucial advantage when analyzing atmospheric characteristics that require joint knowledge of altitude and pressure or other ...
